Inuit Study Adds Twist to Omega-3 Fatty Acids' Health Story - The New York Times - 0 views

  • Today, at least 10 percent of Americans regularly take fish oil supplements. But recent trials have failed to confirm that the pills prevent heart attacks or stroke. And now the story has an intriguing new twist.
  • he journal Science reported that the ancestors of the Inuit evolved unique genetic adaptations for metabolizing omega-3s and other fatty acids. Those gene variants had drastic effects on Inuit’s bodies, reducing their heights and weights.
  • the discovery raised questions about whether omega-3 fats really were protective for everyone, despite decades of health advice. “The same diet may have different effects on different people,” he said.
  • ...10 more annotations...
  • The researchers found several genetic variants at different locations in the genome that were unusually common in the Inuit, compared with people in Europe or China. Several of these variations occurred within a cluster of genes that direct construction of enzymes called fatty acid desaturases. (The genes are called FADS, for short.)
  • This discovery was particularly tantalizing, because the scientists knew that these enzymes helped regulate the different fats in our bodies, including omega-3 fatty acids.
  • one of these gene variants was present in almost every Inuit in the study. It is much less common in other populations: About a quarter of Chinese people have it, compared with just 2 percent of Europeans.
  • Natural selection is the only known way this gene variant could have become so common in the Inuit. Dr. Nielsen said this adaptation might have arisen as long ago as 20,000 years, when the ancestors of the Inuit were living in the Beringia region, which straddles Alaska and Siberia
  • To uncover the effect of this variant gene, the scientists compared the Inuit in their study with others with more European ancestry. Some had inherited a European version of the variant. People with two copies of the Inuit gene had different blood levels of fatty acids than people without them, the researchers found.
  • The adaptation did more than just change blood levels of fatty acids, the scientists found. Inuit who carried two copies of the variant gene were on average an inch shorter and 10 pounds lighter than those without a copy.“That’s quite extreme,” said Dr. Nielsen.
  • Indeed, it’s rare to find a single gene that can influence height and weight so drastically. In recent years, scientists have run a number of large studies pinpointing hundreds of genes that affect height and weight, but each one played a minuscule role in the variation from person to person.
  • Those studies missed this influential gene variant because they focused mostly on people of European ancestry. So Dr. Nielsen and his colleagues also investigated how it affects Europeans. As it turns out, the gene variant is linked to a drastic drop in height and weight in that population, too.
  • natural selection might not have favored the FADS variant but a neighboring, as yet unknown piece of DNA that conferred evolutionary advantages.As that gene spread through the Inuit population, the FADS variant might simply have been passed down with it.
  • Dr. Nielsen and his colleagues are planning to investigate the long-term health effects of the gene variants they’ve found. They may help explain why some of us metabolize fats more effectively than others, and why omega-3s haven’t been the heart panacea once hoped.

genetic dna Iceland genome history

  • Scientists in Iceland have produced an unprecedented snapshot of a nation’s genetic makeup, discovering a host of previously unknown gene mutations that may play roles in ailments as diverse as Alzheimer’s disease, heart disease and gallstones.
  • Decode, an Icelandic genetics firm owned by Amgen, described sequencing the genomes — the complete DNA — of 2,636 Icelanders, the largest collection ever analyzed in a single human population.
  • With this trove of genetic information, the scientists were able to accurately infer the genomes of more than 100,000 other Icelanders, or almost a third of the entire country
  • ...10 more annotations...
  • While some diseases, like cystic fibrosis, are caused by a single genetic mutation, the most common ones are not. Instead, mutations to a number of different genes can each raise the risk of getting, say, heart disease or breast cancer. Discovering these mutations can shed light on these diseases and point to potential treatments. But many of them are rare, making it necessary to search large groups of people to find them.
  • The wealth of data created in Iceland may enable scientists to begin doing that
  • For example, they found eight people in Iceland who shared a mutation on a gene called MYL4. Medical records showed that they also have early onset atrial fibrillation, a type of irregular heartbeat.
  • they identified a gene called ABCA7 as a risk factor for Alzheimer’s disease.Previous studies had suggested a gene in the genetic neighborhood of ABCA7 was associated with the disease.But the Icelandic study pinpointed the gene itself — and even the specific mutation involved.
  • Since Dr. Stefansson and his colleagues submitted their initial results for publication, they have continued gathering DNA from Icelanders.The scientists now have full genomes from about 10,000 Icelanders and partial genetic information on 150,000 more.
  • Dr. Stefansson said that means that his firm could generate a report for genetic disease on every person in Iceland
  • Iceland is a particularly fertile country for doing genetics research. It was founded by a small number of settlers from Europe arriving about 1,100 years ago. Between 8,000 and 20,000 people came mainly from Scandinavia, Ireland and Scotland.
  • The country remained isolated for the next thousand years, and so living Icelanders have a relatively low level of genetic diversity. This makes it easier for scientists to detect genetic variants that raise the risk of disease, because there are fewer of them to examine.
  • celand also has impressive genealogical records. Through epic poems and historical documents, many Icelanders can trace their ancestry back to the nation’s earliest arrivals. Geneticists use national genealogy databases to look for diseases that are unusually common in relatives — a sign that they share a mutation.
  • the company is now investigating a gene, found by Decode, with a strong link to cardiovascular disease in Iceland. (He declined to name the gene.)

anti-malarial mosquitos genetic modification technology science the guardian health

shared by katyshannon on 24 Nov 15 - No Cached
  • Hundreds of genetically modified mosquitoes that are incapable of spreading the malaria parasite to humans have been created in a laboratory as part of a radical approach to combating the disease.
  • The move marks a major step towards the development of a powerful and controversial technology called a “gene drive” that aims to tackle the disease by forcing anti-malarial genes into swarms of wild mosquitoes.
  • The procedure can rapidly transform the genetic makeup of natural insect populations, making it a dramatic new tool in the fight against an infection that still claims over 400,000 lives a year. The same technology is being considered for other human diseases and infections that devastate crops.

  • They call on scientists to ensure that experimental organisms cannot escape from their labs, be released on purpose, or even find their way out accidentally in the event of a natural disaster. Researchers should also be open about the precautions they take to prevent an unintended release, they said.
  • But gene drive technology is so powerful that leading researchers have urged scientists in the field to be cautious. A warning published in August in the prestigious journal Science, by teams in the UK, US, Australia and Japan, said that while gene drives have the potential to save lives and bring other benefits, the accidental release of modified organisms “could have unpredictable ecological consequences.”
  • In the latest study, mosquitoes were engineered to carry genes for antibodies that target the human malaria parasite, Plasmodium falciparum. When released into the wild, researchers believe the modified insects will breed with normal mosquitoes and pass the anti-malarial genes on to their young, making an ever-increasing proportion of future generations resistant to the malaria parasite.
  • In lab tests, the modified mosquitoes passed on their anti-malarial genes to 99.5% of their offspring, suggesting that the procedure was incredibly effective and efficient. To track which insects inherited the antibody genes, the scientists added a tracer gene that gave carriers red fluorescent eyes.

      Keep in mind that this was a trial with only 10 patients. Yes, the results are promising, but there's still a long way to go. It's also imperative to remember how harmful CRISPR Cas 9 technology can be when used incorrectly and without regulation.
  • About a year after getting the treatment, it was working so well that Gray felt comfortable flying for the first time.
  • NPR has had exclusive access to follow Gray through her experience since she underwent the landmark treatment on July 2, 2019. Since the last time NPR checked in with Gray in June, she has continued to improve. Researchers have become increasingly confident that the approach is safe, working for her and will continue to work. Moreover, they are becoming far more encouraged that her case is far from a fluke.

  • Gray is the first person in the United States to be successfully treated for a genetic disorder with the help of CRISPR, a revolutionary gene-editing technique that makes it much easier to make very precise changes in DNA.
  • All the patients appear to have responded well. The only side effects have been from the intense chemotherapy they've had to undergo before getting the billions of edited cells infused into their bodies.
  • The New England Journal of Medicine published online this month the first peer-reviewed research paper from the study, focusing on Gray and the first beta thalassemia patient who was treated.
  • "I'm very excited to see these results," says Jennifer Doudna of the University of California, Berkeley, who shared the Nobel Prize this year for her role in the development of CRISPR
  • But the results from the first 10 patients "represent an important scientific and medical milestone," says Dr. David Altshuler, Vertex's chief scientific officer.

  • For the treatment, doctors remove stem cells from the patients' bone marrow and use CRISPR to edit a gene in the cells, activating the production of fetal hemoglobin. That protein is produced by fetuses in the womb but usually shuts off shortly after birth. The patients then undergo a grueling round of chemotherapy to destroy most of their bone marrow to make room for the gene-edited cells, billions of which are then infused into their bodies.
  • Doctors have already started trying to use CRISPR to treat cancer and to restore vision to people blinded by a genetic disease. They hope to try it for many other diseases as well, including heart disease and AIDS.

  • Unlike routine tests for diabetes or high cholesterol, however, the BRCA gene evaluation — performed by only one company in the United States, Myriad Genetics — is phenomenally expensive, with a “list price” close to $4,000
  • We’re paying this lofty price in large part because Myriad owns broad patents on these two BRCA genes, which it acquired in 1997 and 1998, respectively — and refuses to license the test to any other American company.
  • Without competition, Myriad can effectively charge whatever it wants. Later this year, the company said it would begin incorporating the BRCA test into a 25-gene cancer-risk evaluation and phase out the à la carte BRCA test by 2015. For that broader test, it projects a gross profit margin of 87 percent.

Nor should we let other preventive measures that can save thousands of lives be priced at levels far above what normal “market conditions” would suggest.

human evolution genetics research

shared by Javier E on 15 Feb 13 - No Cached
  • researchers have identified a mutation in a critical human gene as the source of several distinctive traits that make East Asians different from other races.
  • The traits — thicker hair shafts, more sweat glands, characteristically identified teeth and smaller breasts — are the result of a gene mutation that occurred about 35,000 years ago, the researchers have concluded.
  • When the mice grew up, the researchers found they did indeed have thicker hair shafts, confirming that the changed gene was the cause of East Asians’ thicker hair. But the gene had several other effects, they report in Thursday’s issue of the journal Cell. One was that the mice, to the researchers’ surprise, had extra sweat glands. A Chinese member of the team, Sijia Wang, then tested people in China and discovered that they, too, had more numerous sweat glands, evidently another effect of the gene. Another surprise was that the engineered mice had less breast tissue, meaning that EDAR could be the reason that East Asian women have generally smaller breasts.
  • ...4 more annotations...
  • The finding that the gene has so many effects raises the question of which one was the dominant trigger for natural selection. Dr. Sabeti said the extra sweat glands could have been the feature favored by natural selection, with all the other effects being dragged along in its train.
  • East Asians are sometimes assumed to have evolved in a cold environment because of their narrow nostrils, which conserve heat, and the extra eyelid fat that insulates the eye. But the Broad team calculates that the EDAR variant arose about 35,000 years ago in central China and that the region was then quite warm and humid. Extra sweat glands would have been advantageous to the hunter-gatherers who lived at that time.
  • But Joshua Akey, a geneticist at the University of Washington in Seattle, said he thought the more likely cause of the gene’s spread among East Asians was sexual selection. Thick hair and small breasts are visible sexual signals which, if preferred by men, could quickly become more common as the carriers had more children.
  • each of the effects of the EDAR variant may have been favored by natural selection at a different time. A series of selections on different traits thus made the variant version so common among East Asians. About 93 percent of Han Chinese carry the variant, as do about 70 percent of people in Japan and Thailand, and 60 to 90 percent of American Indians, a population descended from East Asians.

genes memes temes replicator evolution

shared by Javier E on 23 Aug 10 - Cached
  • I want to make three arguments here. Imitation is not just some new minor ability. It changes everything. It enables a new kind of evolution. The first is that humans are unique because they are so good at imitation. When our ancestors began to imitate they let loose a new evolutionary process based not on genes but on a second replicator, memes. Genes and memes then coevolved, transforming us into better and better meme machines. The second is that one kind of copying can piggy-back on another: that is, one replicator (the information that is copied) can build on the products (vehicles or interactors) of another. This multilayered evolution has produced the amazing complexity of design we see all around us. The third is that now, in the early 21st century, we are seeing the emergence of a third replicator. I call these temes (short for technological memes, though I have considered other names). They are digital information stored, copied, varied and selected by machines. We humans like to think we are the designers, creators and controllers of this newly emerging world but really we are stepping stones from one replicator to the next.
  • could any of our modern meme products take the step our hominid ancestors did long ago and begin a new kind of copying? Yes. They could and they are. Our computers, all linked up through the Internet, are beginning to carry out all three of the critical processes required for a new evolutionary process to take off.
  • This is a radically new kind of copying, varying and selecting, and means that a new evolutionary process is starting up. This copying is quite different from the way cells copy strands of DNA or humans copy memes. The information itself is also different, consisting of highly stable digital information stored and processed by machines rather than living cells. This, I submit, signals the emergence of temes and teme machines, the third replicator.
  • ...1 more annotation...
  • Just as human meme machines spread over the planet, using up its resources and altering its ecosystems to suit their own needs, so the new teme machines will do the same, only faster. Indeed we might see our current ecological troubles not as primarily our fault, but as the inevitable consequence of earth’s transition to being a three-replicator planet. We willingly provide ever more energy to power the Internet, and there is enormous scope for teme machines to grow, evolve and create ever more extraordinary digital worlds, some aided by humans and others independent of them. We are still needed, not least to run the power stations, but as the temes proliferate, using ever more energy and resources, our own role becomes ever less significant, even though we set the whole new evolutionary process in motion in the first place.

neanderthal human origins

shared by Javier E on 31 Jan 14 - No Cached
  • two new studies have traced the history of Neanderthal DNA, and have pinpointed a number of genes that may have medical importance today.
  • Among the findings, the studies have found clues to the evolution of skin and fertility, as well as susceptibility to diseases like diabetes. More broadly, they show how the legacy of Neanderthals has endured 30,000 years after their extinction.
  • Both studies suggest that Neanderthal genes involved in skin and hair were favored by natural selection in humans. Today, they are very common in living non-Africans.
  • ...3 more annotations...
  • It is possible, Dr. Akey speculated, that the genes developed to help Neanderthal skin adapt to the cold climate of Europe and Asia.
  • Both teams of scientists also found long stretches of the living human genomes where Neanderthal DNA was glaringly absent. This pattern could be produced if modern humans with certain Neanderthal genes could not have as many children on average as people without them. For example, living humans have very few genes from Neanderthals involved in making sperm. That suggests that male human-Neanderthal hybrids might have had lower fertility or were even sterile.
  • Overall, said Dr. Reich, “most of the Neanderthal genetic material was more bad than good.”

theory wilson

shared by Javier E on 15 Oct 11 - No Cached
  • Wilson told me the new proposed evolutionary model pulls the field “out of the fever swamp of kin selection,” and he confidently predicted a coming paradigm shift that would promote genetic research to identify the “trigger” genes that have enabled a tiny number of cases, such as the ant family, to achieve complex forms of cooperation.
  • In the book, he proposes a theory to answer what he calls “the great unsolved problem of biology,” namely how roughly two dozen known examples in the history of life—humans, wasps, termites, platypodid ambrosia beetles, bathyergid mole rats, gall-making aphids, one type of snapping shrimp, and others—made the breakthrough to life in highly social, complex societies. Eusocial species, Wilson noted, are by far “the most successful species in the history of life.”
  • Summarizing parts of it for me, Wilson was particularly unsparing of organized religion, likening the Book of Revelation, for example, to the ranting of “a paranoid schizophrenic who was allowed to write down everything that came to him.” Toward philosophy, he was only slightly kinder. Generation after generation of students have suffered trying to “puzzle out” what great thinkers like Socrates, Plato, and Descartes had to say on the great questions of man’s nature, Wilson said, but this was of little use, because philosophy has been based on “failed models of the brain.”
  • ...6 more annotations...
  • His theory draws upon many of the most prominent views of how humans emerged. These range from our evolution of the ability to run long distances to our development of the earliest weapons, which involved the improvement of hand-eye coordination. Dramatic climate change in Africa over the course of a few tens of thousands of years also may have forced Australopithecus and Homo to adapt rapidly. And over roughly the same span, humans became cooperative hunters and serious meat eaters, vastly enriching our diet and favoring the development of more-robust brains. By themselves, Wilson says, none of these theories is satisfying. Taken together, though, all of these factors pushed our immediate prehuman ancestors toward what he called a huge pre-adaptive step: the formation of the earliest communities around fixed camps.
  • “When humans started having a camp—and we know that Homo erectus had campsites—then we know they were heading somewhere,” he told me. “They were a group progressively provisioned, sending out some individuals to hunt and some individuals to stay back and guard the valuable campsite. They were no longer just wandering through territory, emitting calls. They were on long-term campsites, maybe changing from time to time, but they had come together. They began to read intentions in each other’s behavior, what each other are doing. They started to learn social connections more solidly.”
  • “The humans become consistent with all the others,” he said, and the evolutionary steps were likely similar—beginning with the formation of groups within a freely mixing population, followed by the accumulation of pre-adaptations that make eusociality more likely, such as the invention of campsites. Finally comes the rise to prevalence of eusocial alleles—one of two or more alternative forms of a gene that arise by mutation, and are found at the same place on a chromosome—which promote novel behaviors (like communal child care) or suppress old, asocial traits. Now it is up to geneticists, he adds, to “determine how many genes are involved in crossing the eusociality threshold, and to go find those genes.”
  • Wilson posits that two rival forces drive human behavior: group selection and what he calls “individual selection”—competition at the level of the individual to pass along one’s genes—with both operating simultaneously. “Group selection,” he said, “brings about virtue, and—this is an oversimplification, but—individual selection, which is competing with it, creates sin. That, in a nutshell, is an explanation of the human condition.
  • “Within groups, the selfish are more likely to succeed,” Wilson told me in a telephone conversation. “But in competition between groups, groups of altruists are more likely to succeed. In addition, it is clear that groups of humans proselytize other groups and accept them as allies, and that that tendency is much favored by group selection.” Taking in newcomers and forming alliances had become a fundamental human trait, he added, because “it is a good way to win.”
  • If Wilson is right, the human impulse toward racism and tribalism could come to be seen as a reflection of our genetic nature as much as anything else—but so could the human capacity for altruism, and for coalition- and alliance-building. These latter possibilities may help explain Wilson’s abiding optimism—about the environment and many other matters. If these traits are indeed deeply written into our genetic codes, we might hope that we can find ways to emphasize and reinforce them, to build problem-solving coalitions that can endure, and to identify with progressively larger and more-inclusive groups over time.

method human genome modification

shared by Javier E on 20 Mar 15 - No Cached
  • A group of leading biologists on Thursday called for a worldwide moratorium on use of a new genome-editing technique that would alter human DNA in a way that can be inherited.
  • The biologists fear that the new technique is so effective and easy to use that some physicians may push ahead before its safety can be assessed. They also want the public to understand the ethical issues surrounding the technique, which could be used to cure genetic diseases, but also to enhance qualities like beauty or intelligence. The latter is a path that many ethicists believe should never be taken.
  • a technique invented in 2012 makes it possible to edit the genome precisely and with much greater ease. The technique has already been used to edit the genomes of mice, rats and monkeys, and few doubt that it would work the same way in people.
  • ...8 more annotations...
  • The technique holds the power to repair or enhance any human gene. “It raises the most fundamental of issues about how we are going to view our humanity in the future and whether we are going to take the dramatic step of modifying our own germline and in a sense take control of our genetic destiny, which raises enormous peril for humanity,”
  • The paper’s authors, however, are concerned about countries that have less regulation in science. They urge that “scientists should avoid even attempting, in lax jurisdictions, germline genome modification for clinical application in humans” until the full implications “are discussed among scientific and governmental organizations.”
  • Though such a moratorium would not be legally enforceable and might seem unlikely to exert global influence, there is a precedent. In 1975, scientists worldwide were asked to refrain from using a method for manipulating genes, the recombinant DNA technique, until rules had been established.
  • Though highly efficient, the technique occasionally cuts the genome at unintended sites. The issue of how much mistargeting could be tolerated in a clinical setting is one that Dr. Doudna’s group wants to see thoroughly explored before any human genome is edited.
  • “We worry about people making changes without the knowledge of what those changes mean in terms of the overall genome,” Dr. Baltimore said. “I personally think we are just not smart enough — and won’t be for a very long time — to feel comfortable about the consequences of changing heredity, even in a single individual.”
  • Many ethicists have accepted the idea of gene therapy, changes that die with the patient, but draw a clear line at altering the germline, since these will extend to future generations. The British Parliament in February approved the transfer of mitochondria, small DNA-containing organelles, to human eggs whose own mitochondria are defective. But that technique is less far-reaching because no genes are edited.
  • There are two broad schools of thought on modifying the human germline, said R. Alta Charo, a bioethicist at the University of Wisconsin and a member of the Doudna group. One is pragmatic and seeks to balance benefit and risk. The other “sets up inherent limits on how much humankind should alter nature,” she said. Some Christian doctrines oppose the idea of playing God, whereas in Judaism and Islam there is the notion “that humankind is supposed to improve the world.” She described herself as more of a pragmatist, saying, “I would try to regulate such things rather than shut a new technology down at its beginning.
  • The Doudna group calls for public discussion, but is also working to develop some more formal process, such as an international meeting convened by the National Academy of Sciences, to establish guidelines for human use of the genome-editing technique.“We need some principled agreement that we want to enhance humans in this way or we don’t,” Dr. Jaenisch said. “You have to have this discussion because people are gearing up to do this.”

  • RULES? MORE RULES? REALLY? Isn’t life complicated enough, restricting enough, without abstract rules that don’t take our unique, individual situations into account? And given that our brains are plastic, and all develop differently based on our life experiences, why even expect that a few rules might be helpful to us all?
  • “I’ve got some good news…and I’ve got some bad news,” the lawgiver yells to them. “Which do you want first?” “The good news!” the hedonists reply. “I got Him from fifteen commandments down to ten!” “Hallelujah!” cries the unruly crowd. “And the bad?” “Adultery is still in.”
  • Maps of Meaning was sparked by Jordan’s agonized awareness, as a teenager growing up in the midst of the Cold War, that much of mankind seemed on the verge of blowing up the planet to defend their various identities. He felt he had to understand how it could be that people would sacrifice everything for an “identity,”
  • ...297 more annotations...
  • the story of the golden calf also reminds us that without rules we quickly become slaves to our passions—and there’s nothing freeing about that.
  • And the story suggests something more: unchaperoned, and left to our own untutored judgment, we are quick to aim low and worship qualities that are beneath us—in this case, an artificial animal that brings out our own animal instincts in a completely unregulated way.
  • Similarly, in this book Professor Peterson doesn’t just propose his twelve rules, he tells stories, too, bringing to bear his knowledge of many fields as he illustrates and explains why the best rules do not ultimately restrict us but instead facilitate our goals and make for fuller, freer lives.
  • Peterson wasn’t really an “eccentric”; he had sufficient conventional chops, had been a Harvard professor, was a gentleman (as cowboys can be) though he did say damn and bloody a lot, in a rural 1950s sort of way. But everyone listened, with fascination on their faces, because he was in fact addressing questions of concern to everyone at the table.
  • unlike many academics who take the floor and hold it, if someone challenged or corrected him he really seemed to like it. He didn’t rear up and neigh. He’d say, in a kind of folksy way, “Yeah,” and bow his head involuntarily, wag it if he had overlooked something, laughing at himself for overgeneralizing. He appreciated being shown another side of an issue, and it became clear that thinking through a problem was, for him, a dialogic process.
  • for an egghead Peterson was extremely practical. His examples were filled with applications to everyday life: business management, how to make furniture (he made much of his own), designing a simple house, making a room beautiful (now an internet meme) or in another, specific case related to education, creating an online writing project that kept minority students from dropping out of school by getting them to do a kind of psychoanalytic exercise on themselves,
  • These Westerners were different: self-made, unentitled, hands on, neighbourly and less precious than many of their big-city peers, who increasingly spend their lives indoors, manipulating symbols on computers. This cowboy psychologist seemed to care about a thought only if it might, in some way, be helpful to someone.
  • I was drawn to him because here was a clinician who also had given himself a great books education, and who not only loved soulful Russian novels, philosophy and ancient mythology, but who also seemed to treat them as his most treasured inheritance. But he also did illuminating statistical research on personality and temperament, and had studied neuroscience. Though trained as a behaviourist, he was powerfully drawn to psychoanalysis with its focus on dreams, archetypes, the persistence of childhood conflicts in the adult, and the role of defences and rationalization in everyday life. He was also an outlier in being the only member of the research-oriented Department of Psychology at the University of Toronto who also kept a clinical practice.
  • Maps of Meaning, published nearly two decades ago, shows Jordan’s wide-ranging approach to understanding how human beings and the human brain deal with the archetypal situation that arises whenever we, in our daily lives, must face something we do not understand.
  • The brilliance of the book is in his demonstration of how rooted this situation is in evolution, our DNA, our brains and our most ancient stories. And he shows that these stories have survived because they still provide guidance in dealing with uncertainty, and the unavoidable unknown.
  • this is why many of the rules in this book, being based on Maps of Meaning, have an element of universality to them.
  • We are ambivalent about rules, even when we know they are good for us. If we are spirited souls, if we have character, rules seem restrictive, an affront to our sense of agency and our pride in working out our own lives. Why should we be judged according to another’s rule?
  • And he felt he had to understand the ideologies that drove totalitarian regimes to a variant of that same behaviour: killing their own citizens.
  • Ideologies are simple ideas, disguised as science or philosophy, that purport to explain the complexity of the world and offer remedies that will perfect it.
  • Ideologues are people who pretend they know how to “make the world a better place” before they’ve taken care of their own chaos within.
  • Ideologies are substitutes for true knowledge, and ideologues are always dangerous when they come to power, because a simple-minded I-know-it-all approach is no match for the complexity of existence.
  • To understand ideology, Jordan read extensively about not only the Soviet gulag, but also the Holocaust and the rise of Nazism. I had never before met a person, born Christian and of my generation, who was so utterly tormented by what happened in Europe to the Jews, and who had worked so hard to understand how it could have occurred.
  • I saw what now millions have seen online: a brilliant, often dazzling public speaker who was at his best riffing like a jazz artist; at times he resembled an ardent Prairie preacher (not in evangelizing, but in his passion, in his ability to tell stories that convey the life-stakes that go with believing or disbelieving various ideas). Then he’d just as easily switch to do a breathtakingly systematic summary of a series of scientific studies. He was a master at helping students become more reflective, and take themselves and their futures seriously. He taught them to respect many of the greatest books ever written. He gave vivid examples from clinical practice, was (appropriately) self-revealing, even of his own vulnerabilities, and made fascinating links between evolution, the brain and religious stories.
  • Above all, he alerted his students to topics rarely discussed in university, such as the simple fact that all the ancients, from Buddha to the biblical authors, knew what every slightly worn-out adult knows, that life is suffering.
  • chances are, if you or someone you love is not suffering now, they will be within five years, unless you are freakishly lucky. Rearing kids is hard, work is hard, aging, sickness and death are hard, and Jordan emphasized that doing all that totally on your own, without the benefit of a loving relationship, or wisdom, or the psychological insights of the greatest psychologists, only makes it harder.
  • focused on triumphant heroes. In all these triumph stories, the hero has to go into the unknown, into an unexplored territory, and deal with a new great challenge and take great risks. In the process, something of himself has to die, or be given up, so he can be reborn and meet the challenge. This requires courage, something rarely discussed in a psychology class or textbook.

As we travelled the seas and explored the globe, we learned of far-flung tribes on different continents whose different moral codes made sense relative to, or within the framework of, their societies. Science played a role, too, by attacking the religious view of the world, and thus undermining the religious grounds for ethics and rules. Materialist social science implied that we could divide the world into facts (which all could observe, and were objective and “real”) and values (…

  • if it’s uncertain that our ideals are attainable, why do we bother reaching in the first place? Because if you don’t reach for them, it is certain you will never feel that your life has meaning.
  • And perhaps because, as unfamiliar and strange as it sounds, in the deepest part of our psyche, we all want to be judged.
  • Instead of despairing about these differences in moral codes, Aristotle argued that though specific rules, laws and customs differed from place to place, what does not differ is that in all places human beings, by their nature, have a proclivity to make rules, laws and customs.
  • Freud never argued (as do some who want all culture to become one huge group therapy session) that one can live one’s entire life without ever making judgments, or without morality. In fact, his point in Civilization and Its Discontents is that civilization only arises when some restraining rules and morality are in place.
  • Aleksandr Solzhenitsyn, the great documenter of the slave-labour-camp horrors of the latter, once wrote that the “pitiful ideology” holding that “human beings are created for happiness” was an ideology “done in by the first blow of the work assigner’s cudgel.”1 In a crisis, the inevitable suffering that life entails can rapidly make a mockery of the idea that happiness is the proper pursuit of the individual. On the radio show, I suggested, instead, that a deeper meaning was required. I noted that the nature of such meaning was constantly re-presented in the great stories of the past, and that it had more to do with developing character in the face of suffering than with happiness.
  • I proposed in Maps of Meaning that the great myths and religious stories of the past, particularly those derived from an earlier, oral tradition, were moral in their intent, rather than descriptive. Thus, they did not concern themselves with what the world was, as a scientist might have it, but with how a human being should act.
  • I suggested that our ancestors portrayed the world as a stage—a drama—instead of a place of objects. I described how I had come
  • to believe that the constituent elements of the world as drama were order and chaos, and not material things.
  • Order is where the people around you act according to well-understood social norms, and remain predictable and cooperative. It’s the world of social structure, explored territory, and familiarity. The state of Order is typically portrayed, symbolically—imaginatively—as masculine.
  • Chaos, by contrast, is where—or when—something unexpected happens.
  • As the antithesis of symbolically masculine order, it’s presented imaginatively as feminine. It’s the new and unpredictable suddenly emerging in the midst of the commonplace familiar. It’s Creation and Destruction,
  • Order is the white, masculine serpent; Chaos, its black, feminine counterpart. The black dot in the white—and the white in the black—indicate the possibility of transformation: just when things seem secure, the unknown can loom, unexpectedly and large. Conversely, just when everything seems lost, new order can emerge from catastrophe and chaos.
  • For the Taoists, meaning is to be found on the border between the ever-entwined pair. To walk that border is to stay on the path of life, the divine Way. And that’s much better than happiness.
  • trying to address a perplexing problem: the reason or reasons for the nuclear standoff of the Cold War. I couldn’t understand how belief systems could be so important to people that they were willing to risk the destruction of the world to protect them. I came to realize that shared belief systems made people intelligible to one another—and that the systems weren’t just about belief.
  • People who live by the same code are rendered mutually predictable to one another. They act in keeping with each other’s expectations and desires. They can cooperate. They can even compete peacefully, because everyone knows what to expect from everyone else.
  • Shared beliefs simplify the world, as well, because people who know what to expect from one another can act together to tame the world. There is perhaps nothing more important than the maintenance of this organization—this simplification. If it’s threatened, the great ship of state rocks.
  • It isn’t precisely that people will fight for what they believe. They will fight, instead, to maintain the match between what they believe, what they expect, and what they desire. They will fight to maintain the match between what they expect and how everyone is acting. It is precisely the maintenance of that match that enables everyone
  • There’s more to it, too. A shared cultural system stabilizes human interaction, but is also a system of value—a hierarchy of value, where some things are given priority and importance and others are not. In the absence of such a system of value, people simply cannot act. In fact, they can’t even perceive, because both action and perception require a goal, and a valid goal is, by necessity, something valued.
  • We experience much of our positive emotion in relation to goals. We are not happy, technically speaking, unless we see ourselves progressing—and the very idea of progression implies value.
  • Worse yet is the fact that the meaning of life without positive value is not simply neutral. Because we are vulnerable and mortal, pain and anxiety are an integral part of human existence. We must have something to set against the suffering that is intrinsic to Being.*2 We must have the meaning inherent in a profound system of value or the horror of existence rapidly becomes paramount. Then, nihilism beckons, with its hopelessness and despair.
  • So: no value, no meaning. Between value systems, however, there is the possibility of conflict. We are thus eternally caught between the most diamantine rock and the hardest of places:
  • loss of group-centred belief renders life chaotic, miserable, intolerable; presence of group-centred belief makes conflict with other groups inevitable.
  • In the West, we have been withdrawing from our tradition-, religion- and even nation-centred cultures, partly to decrease the danger of group conflict. But we are increasingly falling prey to the desperation of meaninglessness, and that is no improvement at all.
  • While writing Maps of Meaning, I was (also) driven by the realization that we can no longer afford conflict—certainly not on the scale of the world conflagrations of the twentieth century.
  • I came to a more complete, personal realization of what the great stories of the past continually insist upon: the centre is occupied by the individual.
  • It is possible to transcend slavish adherence to the group and its doctrines and, simultaneously, to avoid the pitfalls of its opposite extreme, nihilism. It is possible, instead, to find sufficient meaning in individual consciousness and experience.
  • How could the world be freed from the terrible dilemma of conflict, on the one hand, and psychological and social dissolution, on the other? The answer was this: through the elevation and development of the individual, and through the willingness of everyone to shoulder the burden of Being and to take the heroic path. We must each adopt as much responsibility as possible for individual life, society and the world.
  • We must each tell the truth and repair what is in disrepair and break down and recreate what is old and outdated. It is in this manner that we can and must reduce the suffering that poisons the world. It’s asking a lot. It’s asking for everything.
  • the alternative—the horror of authoritarian belief, the chaos of the collapsed state, the tragic catastrophe of the unbridled natural world, the existential angst and weakness of the purposeless
  • individual—is clearly worse.
  • a title: 12 Rules for Life: An Antidote to Chaos. Why did that one rise up above all others? First and foremost, because of its simplicity. It indicates clearly that people need ordering principles, and that chaos otherwise beckons.
  • We require rules, standards, values—alone and together. We’re pack animals, beasts of burden. We must bear a load, to justify our miserable existence. We require routine and tradition. That’s order. Order can become excessive, and that’s not good, but chaos can swamp us, so we drown—and that is also not good. We need to stay on the straight and narrow path.
  • I hope that these rules and their accompanying essays will help people understand what they already know: that the soul of the individual eternally hungers for the heroism of genuine Being, and that the willingness to take on that responsibility is identical to the decision to live a meaningful life.
  • RULE 1   STAND UP STRAIGHT WITH YOUR SHOULDERS BACK
  • Because territory matters, and because the best locales are always in short supply, territory-seeking among animals produces conflict. Conflict, in turn, produces another problem: how to win or lose without the disagreeing parties incurring too great a cost.
  • It’s winner-take-all in the lobster world, just as it is in human societies, where the top 1 percent have as much loot as the bottom 50 percent11—and where the richest eighty-five people have as much as the bottom three and a half billion.
  • This principle is sometimes known as Price’s law, after Derek J. de Solla Price,13 the researcher who discovered its application in science in 1963. It can be modelled using an approximately L-shaped graph, with number of people on the vertical axis, and productivity or resources on the horizontal.
  • Instead of undertaking the computationally difficult task of identifying the best man, the females outsource the problem to the machine-like calculations of the dominance hierarchy. They let the males fight it out and peel their paramours from the top.
  • The dominant male, with his upright and confident posture, not only gets the prime real estate and easiest access to the best hunting grounds. He also gets all the girls. It is exponentially more worthwhile to be successful, if you are a lobster, and male.
  • dominance hierarchies have been an essentially permanent feature of the environment to which all complex life has adapted. A third of a billion years ago, brains and nervous systems were comparatively simple. Nonetheless, they already had the structure and neurochemistry necessary to process information about status and society. The importance of this fact can hardly be overstated.
  • evolution works, in large part, through variation and natural selection. Variation exists for many reasons, including gene-shuffling (to put it simply) and random mutation. Individuals vary within a species for such reasons. Nature chooses from among them, across time. That theory, as stated, appears to account for the continual alteration of life-forms over the eons.
  • But there’s an additional question lurking under the surface: what exactly is the “nature” in “natural selection”? What exactly is “the environment” to which animals adapt?
  • Nature “selects.” The idea of selects contains implicitly nested within it the idea of fitness. It is “fitness” that is “selected.” Fitness, roughly speaking, is the probability that a given organism will leave offspring (will propagate its genes through time). The “fit” in “fitness” is therefore the matching of organismal attribute to environmental demand.
  • But nature, the selecting agent, is not a static selector—not in any simple sense.
  • As the environment supporting a species transforms and changes, the features that make a given individual successful in surviving and reproducing also transform and change. Thus, the theory of natural selection does not posit creatures matching themselves ever more precisely to a template specified by the world. It is more that creatures are in a dance with nature, albeit one that is deadly.
  • Nature is not simply dynamic, either. Some things change quickly, but they are nested within other things that change less quickly (music
  • It’s chaos, within order, within chaos, within higher order. The order that is most real is the order that is most unchanging—and that is not necessarily the order that is most easily seen. The leaf, when perceived, might blind the observer to the tree. The tree can blind him to the forest.
  • It is also a mistake to conceptualize nature romantically.
  • Unfortunately, “the environment” is also elephantiasis and guinea worms (don’t ask), anopheles mosquitoes and malaria, starvation-level droughts, AIDS and the Black Plague.
  • It is because of the existence of such things, of course, that we attempt to modify our surroundings, protecting our children, building cities and transportation systems and growing food and generating power.
  • this brings us to a third erroneous concept: that nature is something strictly segregated from the cultural constructs that have emerged within it.
  • It does not matter whether that feature is physical and biological, or social and cultural. All that matters, from a Darwinian perspective, is permanence—and the dominance hierarchy, however social or cultural it might appear, has been around for some half a billion years.
  • The dominance hierarchy is not capitalism. It’s not communism, either, for that matter. It’s not the military-industrial complex. It’s not the patriarchy—that disposable, malleable, arbitrary cultural artefact. It’s not even a human creation; not in the most profound sense. It is instead a near-eternal aspect of the environment, and much of what is blamed on these more ephemeral manifestations is a consequence of its unchanging existence.
  • We were struggling for position before we had skin, or hands, or lungs, or bones. There is little more natural than culture. Dominance hierarchies are older than trees.
  • The part of our brain that keeps track of our position in the dominance hierarchy is therefore exceptionally ancient and fundamental.17 It is a master control system, modulating our perceptions, values, emotions, thoughts and actions. It powerfully affects every aspect of our Being, conscious and unconscious alike.
  • The ancient part of your brain specialized for assessing dominance watches how you are treated by other people. On that evidence, it renders a determination of your value and assigns you a status. If you are judged by your peers as of little worth, the counter restricts serotonin availability. That makes you much more physically and psychologically reactive to any circumstance or event that might produce emotion, particularly if it is negative. You need that reactivity. Emergencies are common at the bottom, and you must be ready to survive. Unfortunately, that physical hyper-response, that constant alertness, burns up a lot of precious energy and physical resources.
  • It will leave you far more likely to live, or die, carelessly, for a rare opportunity at pleasure, when it manifests itself. The physical demands of emergency preparedness will wear you down in every way.21
  • If you have a high status, on the other hand, the counter’s cold, pre-reptilian mechanics assume that your niche is secure, productive
  • You can delay gratification, without forgoing it forever. You can afford to be a reliable and thoughtful citizen.
  • Sometimes, however, the counter mechanism can go wrong. Erratic habits of sleeping and eating can interfere with its function. Uncertainty can throw it for a loop. The body, with its various parts,
  • needs
  • to function like a well-rehearsed orchestra. Every system must play its role properly, and at exactly the right time, or noise and chaos ensue. It is for this reason that routine is so necessary. The acts of life we repeat every day need to be automatized. They must be turned into stable and reliable habits, so they lose their complexity and gain predictability and simplicity.
  • It is for such reasons that I always ask my clinical clients first about sleep. Do they wake up in the morning at approximately the time the typical person wakes up, and at the same time every day?
  • The next thing I ask about is breakfast. I counsel my clients to eat a fat and protein-heavy breakfast as soon as possible after they awaken (no simple carbohydrates, no sugars,
  • I have had many clients whose anxiety was reduced to subclinical levels merely because they started to sleep on a predictable schedule and eat breakfast.
  • Other bad habits can also interfere with the counter’s accuracy.
  • There are many systems of interaction between brain, body and social world that can get caught in positive feedback loops. Depressed people, for example, can start feeling useless and burdensome, as well as grief-stricken and pained. This makes them withdraw from contact with friends and family. Then the withdrawal makes them more lonesome and isolated, and more likely to feel useless and burdensome. Then they withdraw more. In this manner, depression spirals and amplifies.
  • If someone is badly hurt at some point in life—traumatized—the dominance counter can transform in a manner that makes additional hurt more rather than less likely. This often happens in the case of people, now adults, who were viciously bullied during childhood or adolescence. They become anxious and easily upset. They shield themselves with a defensive crouch, and avoid the direct eye contact interpretable as a dominance challenge.
  • With their capacity for aggression strait-jacketed within a too-narrow morality, those who are only or merely compassionate and self-sacrificing (and naïve and exploitable) cannot call forth the genuinely righteous and appropriately self-protective anger necessary to defend themselves. If you can bite, you generally don’t have to. When skillfully integrated, the ability to respond with aggression and violence decreases rather than increases the probability that actual aggression will become necessary.
  • Naive, harmless people usually guide their perceptions and actions with a few simple axioms: people are basically good; no one really wants to hurt anyone else; the threat (and, certainly, the use) of force, physical or otherwise, is wrong. These axioms collapse, or worse, in the presence of
  • individuals who are genuinely malevolent.27
  • I have had clients who were terrified into literally years of daily hysterical convulsions by the sheer look of malevolence on their attackers’ faces. Such individuals typically come from hyper-sheltered families, where nothing
  • terrible is allowed to exist, and everything is fairyland wonderful (or else).
  • When the wakening occurs—when once-naïve people recognize in themselves the seeds of evil and monstrosity, and see themselves as dangerous (at least potentially)— their fear decreases. They develop more self-respect. Then, perhaps, they begin to resist oppression. They see that they have the ability to withstand, because they are terrible too. They see they can and must stand up, because they begin to understand how genuinely monstrous they will become, otherwise,
  • There is very little difference between the capacity for mayhem and destruction, integrated, and strength of character. This is one of the most difficult lessons of life.
  • even if you came by your poor posture honestly—even if you were unpopular or bullied at home or in grade school28—it’s not necessarily appropriate now. Circumstances change. If you slump around, with the same bearing that characterizes a defeated lobster, people will assign you a lower status, and the old counter that you share with crustaceans, sitting at the very base of your brain, will assign you a low dominance number.
  • the other, far more optimistic lesson of Price’s law and the Pareto distribution: those who start to have will probably get more.
  • Some of these upwardly moving loops can occur in your own private, subjective space.
  • If you are asked to move the muscles one by one into a position that looks happy, you will report feeling happier. Emotion is partly bodily expression, and can be amplified (or dampened) by that expression.29
  • To stand up straight with your shoulders back is to accept the terrible responsibility of life, with eyes wide open.
  • It means deciding to voluntarily transform the chaos of potential into the realities of habitable order. It means adopting the burden of self-conscious vulnerability, and accepting the end of the unconscious paradise of childhood, where finitude and mortality are only dimly comprehended. It means willingly undertaking the sacrifices necessary to generate a productive and meaningful reality (it means acting to please God, in the ancient language).
  • So, attend carefully to your posture. Quit drooping and hunching around. Speak your mind. Put your desires forward, as if you had a right to them—at least the same right as others. Walk tall and gaze forthrightly ahead. Dare to be dangerous. Encourage the serotonin to flow plentifully through the neural pathways desperate for its calming influence.
  • Thus emboldened, you will embark on the voyage of your life, let your light shine, so to speak, on the heavenly hill, and pursue your rightful destiny. Then the meaning of your life may be sufficient to keep the corrupting influence of mortal despair at bay. Then you may be able to accept the terrible burden of the World, and find joy.
  • RULE 2   TREAT YOURSELF LIKE SOMEONE YOU ARE RESPONSIBLE FOR HELPING
  • People are better at filling and properly administering prescription medication to their pets than to themselves. That
  • It is difficult to conclude anything from this set of facts except that people appear to love their dogs, cats, ferrets and birds (and maybe even their lizards) more than themselves. How horrible is that? How much shame must exist, for something like that to be true? What could it be about people that makes them prefer their pets to themselves?
  • To understand Genesis 1, the Priestly story, with its insistence on speech as the fundamental creative force, it is first necessary to review a few fundamental, ancient assumptions (these are markedly different in type and intent from the assumptions of science, which are, historically speaking, quite novel).
  • those who existed during the distant time in which the foundational epics of our culture emerged were much more concerned with the actions that dictated survival (and with interpreting the world in a manner commensurate with that goal) than with anything approximating what we now understand as objective truth.
  • Before the dawn of the scientific worldview, reality was construed differently. Being was understood as a place of action, not a place of things.31 It was understood as something more akin to story or drama. That story or drama was lived, subjective experience, as it manifested itself moment to moment in the consciousness of every living person.
  • subjective pain. That’s something so real no argument can stand against it. Everyone acts as if their pain is real—ultimately, finally real. Pain matters, more than matter matters. It is for this reason, I believe, that so many of the world’s traditions regard the suffering attendant upon existence as the irreducible truth of Being.
  • In any case, that which we subjectively experience can be likened much more to a novel or a movie than to a scientific description of physical reality.
  • The Domain, Not of Matter, but of What Matters
  • the world of experience has primal constituents, as well. These are the necessary elements whose interactions define drama and fiction. One of these is chaos. Another is order. The third (as there are three) is the process that mediates between the two, which appears identical to what modern people call consciousness.
  • Chaos is the domain of ignorance itself. It’s unexplored territory. Chaos is what extends, eternally and without limit, beyond the boundaries of all states, all ideas, and all disciplines. It’s the foreigner, the stranger, the member of another gang, the rustle in the bushes in the night-time,
  • It is, in short, all those things and situations we neither know nor understand.
  • Chaos is also the formless potential from which the God of Genesis 1 called forth order using language at the beginning of time. It’s the same potential from which we, made in that Image, call forth the novel and ever-changing moments of our lives. And Chaos is freedom, dreadful freedom, too.
  • Order, by contrast, is explored territory. That’s the hundreds-of-millions-of-years-old hierarchy of place, position and authority. That’s the structure of society. It’s the structure provided by biology, too—particularly insofar as you are adapted, as you are, to the structure of society. Order is tribe, religion, hearth, home and country.
  • Order is the public façade we’re called upon to wear, the politeness of a gathering of civilized strangers, and the thin ice on which we all skate. Order is the place where the behavior of the world matches our expectations and our desires; the place where all things turn out the way we want them to.
  • But order is sometimes tyranny and stultification, as well, when the demand for certainty and uniformity and purity becomes too one-sided.
  • In order, we’re able to think about things in the long term. There, things work, and we’re stable, calm and competent. We seldom leave places we
  • understand—geographical or conceptual—for that reason, and we certainly do not like it when we are compelled to or when it happens accidentally.
  • When the same person betrays you, sells you out, you move from the daytime world of clarity and light to the dark underworld of chaos, confusion and despair. That’s the same move you make, and the same place you visit, when the company you work for starts to fail and your job is placed in doubt.
  • Before the Twin Towers fell—that was order. Chaos manifested itself afterward. Everyone felt it. The very air became uncertain. What exactly was it that fell? Wrong question. What exactly remained standing? That was the issue at hand.
  • Chaos is the deep ocean bottom to which Pinocchio voyaged to rescue his father from Monstro, whale and fire-breathing dragon. That journey into darkness and rescue is the most difficult thing a puppet must do, if he wants to be real; if he wants to extract himself from the temptations of deceit and acting and victimization and impulsive pleasure and totalitarian subjugation; if he wants to take his place as a genuine Being in the world.
  • Chaos is the new place and time that emerges when tragedy strikes suddenly, or malevolence reveals its paralyzing visage, even in the confines of your own home. Something unexpected or undesired can always make its appearance, when a plan is being laid out, regardless of how familiar the circumstances.
  • Our brains respond instantly when chaos appears, with simple, hyper-fast circuits maintained from the ancient days, when our ancestors dwelled in trees, and snakes struck in a flash.32 After that nigh-instantaneous, deeply reflexive bodily response comes the later-evolving, more complex but slower responses of emotions—and, after that, comes thinking, of the higher order, which can extend over seconds, minutes or years. All that response is instinctive, in some sense—but the faster the response, the more instinctive.
  • Things or objects are part of the objective world. They’re inanimate; spiritless. They’re dead. This is not true of chaos and order. Those are perceived, experienced and understood (to the degree that they are understood at all) as personalities—and that is just as true of the perceptions, experiences and understanding of modern people as their ancient forebears. It’s just that moderners don’t notice.
  • Perception of things as entities with personality also occurs before perception of things as things. This is particularly true of the action of others,34 living others, but we also see the non-living “objective world” as animated, with purpose and intent.
  • This is because of the operation of what psychologists have called “the hyperactive agency detector” within us.35 We evolved, over millennia, within intensely social circumstances. This means that the most significant elements of our environment of origin were personalities, not things, objects or situations.

It’s plenty long enough for male and female and parent and child to serve as vital and fundamental parts of the environment to which we have adapted. This means that male and female and parent and child are…

  • Order, the known, appears symbolically associated with masculinity (as illustrated in the aforementioned yang of the Taoist yin-yang symbol). This is perhaps because the primary…
  • Chaos—the unknown—is symbolically associated with the feminine. This is partly because all the things we have come to know were born, originally, of the unknown, just as all beings we encounter were born of mothers. Chaos is mater, origin, source, mother; materia, the substance from which all things are made.
  • In its positive guise, chaos is possibility itself, the source of ideas, the mysterious realm of gestation and birth. As a negative force, it’s the impenetrable darkness of a cave and the accident by the side of the road.
  • Chaos, the eternal feminine, is also the crushing force of sexual selection.
  • Most men do not meet female human standards. It is for this reason that women on dating sites rate 85 percent of men as below average in attractiveness.40
  • Women’s proclivity to say no, more than any other force, has shaped our evolution into the creative, industrious, upright, large-brained (competitive, aggressive, domineering) creatures that we are.42 It is Nature as Woman who says, “Well, bucko, you’re good enough for a friend, but my experience of you so far has not indicated the suitability of your genetic material for continued propagation.”
  • Many things begin to fall into place when you begin to consciously understand the world in this manner. It’s as if the knowledge of your body and soul falls into alignment with the knowledge of your intellect.
  • And there’s more: such knowledge is proscriptive, as well as descriptive. This is the kind of knowing what that helps you know how. This is the kind of is from which you can derive an ought. The Taoist juxtaposition of yin and yang, for example, doesn’t simply portray chaos and order as the fundamental elements of Being—it also tells you how to act.
  • The Way, the Taoist path of life, is represented by (or exists on) the border between the twin serpents. The Way is the path of proper Being. It’s the same Way as that referred to by Christ in John 14:6: I am the way, and the truth and the life. The same idea is expressed in Matthew 7:14: Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it.
  • We eternally inhabit order, surrounded by chaos. We eternally occupy known territory, surrounded by the unknown. We experience meaningful engagement when we mediate appropriately between them. We are adapted, in the deepest Darwinian sense, not to the world of objects, but to the meta-realities of order and chaos, yang and yin. Chaos and order make up the eternal, transcendent environment of the living.
  • To straddle that fundamental duality is to be balanced: to have one foot firmly planted in order and security, and the other in chaos, possibility, growth and adventure.
  • Chaos and order are fundamental elements because every lived situation (even every conceivable lived situation) is made up of both.
  • you need to place one foot in what you have mastered and understood and the other in what you are currently exploring and mastering. Then you have positioned yourself where the terror of existence is under control and you are secure, but where you are also alert and engaged. That is where there is something new to master and some way that you can be improved. That is where meaning is to be found.
  • The serpent in Eden therefore means the same thing as the black dot in the yin side of the Taoist yin/yang symbol of totality—that is, the possibility of the unknown and revolutionary suddenly manifesting itself where everything appears calm.
  • The outside, chaos, always sneaks into the inside, because nothing can be completely walled off from the rest of reality. So even the ultimate in safe spaces inevitably harbours a snake.
  • We have seen the enemy, after all, and he is us. The snake inhabits each of our souls.
  • The worst of all possible snakes is the eternal human proclivity for evil. The worst of all possible snakes is psychological, spiritual, personal, internal. No walls, however tall, will keep that out. Even if the fortress were thick enough, in principle, to keep everything bad whatsoever outside, it would immediately appear again within.
  • I have learned that these old stories contain nothing superfluous. Anything accidental—anything that does not serve the plot—has long been forgotten in the telling. As the Russian playwright Anton Chekhov advised, “If there is a rifle hanging on the wall in act one, it must be fired in the next act. Otherwise it has no
  • business being there.”50
  • Eve immediately shares the fruit with Adam. That makes him self-conscious. Little has changed. Women have been making men self-conscious since the beginning of time. They do this primarily by rejecting them—but they also do it by shaming them, if men do not take responsibility. Since women bear the primary burden of reproduction, it’s no wonder. It is very hard to see how it could be otherwise. But the capacity of women to shame men and render them self-conscious is still a primal force of nature.
  • What does it mean to know yourself naked
  • Naked means vulnerable and easily damaged. Naked means subject to judgment for beauty and health. Naked means unprotected and unarmed in the jungle of nature and man. This is why Adam and Eve became ashamed, immediately after their eyes were opened. They could see—and what they first saw was themselves.
  • In their vulnerability, now fully realized, they felt unworthy to stand before God.
  • Beauty shames the ugly. Strength shames the weak. Death shames the living—and the Ideal shames us all.
  • He tells the woman that she will now bring forth children in sorrow, and desire an unworthy, sometimes resentful man, who will in consequence lord her biological fate over her, permanently. What might this mean? It could just mean that God is a patriarchal tyrant, as politically motivated interpretations of the ancient story insist. I think it’s merely descriptive.
  • women pay a high price for pregnancy and child-rearing, particularly in the early stages, and that one of the inevitable consequences is increased dependence upon the sometimes unreliable and always problematic good graces of men.
  • then God banishes the first man and the first woman from Paradise, out of infancy, out of the unconscious animal world, into the horrors of history itself. And then He puts cherubim and a flaming sword at the gate of Eden, just to stop them from eating the Fruit of the Tree of Life.
  • Perhaps Heaven is something you must build, and immortality something you must earn.
  • so we return to our original query: Why would someone buy prescription medication for his dog, and then so carefully administer it, when he would not do the same for himself?
  • Why should anyone take care of anything as naked, ugly, ashamed, frightened, worthless, cowardly, resentful, defensive and accusatory as a descendant of Adam? Even if that thing, that being, is himself?
  • We know how we are naked, and how that nakedness can be exploited—and that means we know how others are naked, and how they can be exploited. We can terrify other people, consciously. We can hurt and humiliate them for faults we understand only too well. We can torture them—literally—slowly, artfully and terribly. That’s far more than predation. That’s a qualitative shift in understanding. That’s a cataclysm as large as the development of self-consciousness itself. That’s the entry of the knowledge of Good and Evil into the world.
  • Only man could conceive of the rack, the iron maiden and the thumbscrew. Only man will inflict suffering for the sake of suffering. That is the best definition of evil I have been able to formulate.
  • with this realization we have well-nigh full legitimization of the idea, very unpopular in modern intellectual circles, of Original Sin.
  • Human beings have a great capacity for wrongdoing. It’s an attribute that is unique in the world of life. We can and do make things worse, voluntarily, with full knowledge of what we are doing (as well as accidentally, and carelessly, and in a manner that is willfully blind). Given that terrible capacity, that proclivity for malevolent actions, is it any wonder we have a hard time taking care of ourselves, or others—or even that we doubt the value of the entire human enterprise?
  • The juxtaposition of Genesis 1 with Genesis 2 & 3 (the latter two chapters outlining the fall of man, describing why our lot is so tragedy-ridden and ethically torturous) produces a narrative sequence almost unbearable in its profundity. The moral of Genesis 1 is that Being brought into existence through true speech is Good.
  • The original Man and Woman, existing in unbroken unity with their Creator, did not appear conscious (and certainly not self-conscious). Their eyes were not open. But, in their perfection, they were also less, not more, than their post-Fall counterparts. Their goodness was something bestowed, rather than deserved or earned.
  • Maybe, even in some cosmic sense (assuming that consciousness itself is a phenomenon of cosmic significance), free choice matters.
  • here’s a proposition: perhaps it is not simply the emergence of self-consciousness and the rise of our moral knowledge of Death and the Fall that besets us and makes us doubt our own worth. Perhaps it is instead our unwillingness—reflected in Adam’s shamed hiding—to walk with God, despite our fragility and propensity for evil.
  • The entire Bible is structured so that everything after the Fall—the history of Israel, the prophets, the coming of Christ—is presented as a remedy for that Fall, a way out of evil. The beginning of conscious history, the rise of the state and all its pathologies of pride and rigidity, the emergence of great moral figures who try to set things right, culminating in the Messiah Himself—that is all part of humanity’s attempt, God willing, to set itself right. And what would that mean?
  • And this is an amazing thing: the answer is already implicit in Genesis 1: to embody the Image of God—to speak out of chaos the Being that is Good—but to do so consciously, of our own free choice.
  • Back is the way forward—as T. S. Eliot so rightly insisted
  • We shall not cease from exploration And the end of all our exploring Will be to arrive where we started And know the place for the first time.
  • If we wish to take care of ourselves properly, we would have to respect ourselves—but we don’t, because we are—not least in our own eyes—fallen creatures.
  • If we lived in Truth; if we spoke the Truth—then we could walk with God once again, and respect ourselves, and others, and the world. Then we might treat ourselves like people we cared for.
  • We might strive to set the world straight. We might orient it toward Heaven, where we would want people we cared for to dwell, instead of Hell, where our resentment and hatred would eternally sentence everyone.
  • Then, the primary moral issue confronting society was control of violent, impulsive selfishness and the mindless greed and brutality that accompanies it.
  • It is easy to believe that people are arrogant, and egotistical, and always looking out for themselves. The cynicism that makes that opinion a universal truism is widespread and fashionable.
  • But such an orientation to the world is not at all characteristic of many people. They have the opposite problem: they shoulder intolerable burdens of self-disgust, self-contempt, shame and self-consciousness. Thus, instead of narcissistically inflating their own importance, they don’t value themselves at all, and they don’t take care of themselves with attention and skill.
  • Christ’s archetypal death exists as an example of how to accept finitude, betrayal and tyranny heroically—how to walk with God despite the tragedy of self-conscious knowledge—and not as a directive to victimize ourselves in the service of others.
  • To sacrifice ourselves to God (to the highest good, if you like) does not mean to suffer silently and willingly when some person or organization demands more from us, consistently, than is offered in return. That means we are supporting tyranny, and allowing ourselves to be treated like slaves.
  • I learned two very important lessons from Carl Jung, the famous Swiss depth psychologist, about “doing unto others as you would have them do unto you” or “loving your neighbour as yourself.”
  • The first lesson was that neither of these statements has anything to do with being nice. The second was that both are equations, rather than injunctions.
  • If I am someone’s friend, family member, or lover, then I am morally obliged to bargain as hard on my own behalf as they are on theirs.
  • there is little difference between standing up and speaking for yourself, when you are being bullied or otherwise tormented and enslaved, and standing up and speaking for someone else.
  • you do not simply belong to yourself. You are not simply your own possession to torture and mistreat. This is partly because your Being is inexorably tied up with that of others, and your mistreatment of yourself can have catastrophic consequences for others.
  • metaphorically speaking, there is also this: you have a spark of the divine in you, which belongs not to you, but to God. We are, after all—according to Genesis—made in His image.
  • We can make order from chaos—and vice versa—in our way, with our words. So, we may not exactly be God, but we’re not exactly nothing, either.
  • In my own periods of darkness, in the underworld of the soul, I find myself frequently overcome and amazed by the ability of people to befriend each other, to love their intimate partners and parents and children, and to do what they must do to keep the machinery of the world running.
  • It is this sympathy that should be the proper medicament for self-conscious self-contempt, which has its justification, but is only half the full and proper story. Hatred for self and mankind must be balanced with gratefulness for tradition and the state and astonishment at what normal, everyday people accomplish
  • You have some vital role to play in the unfolding destiny of the world. You are, therefore, morally obliged to take care of yourself.
  • To treat yourself as if you were someone you are responsible for helping is, instead, to consider what would be truly good for you. This is not “what you want.” It is also not “what would make you happy.”
  • You must help a child become a virtuous, responsible, awake being, capable of full reciprocity—able to take care of himself and others, and to thrive while doing so. Why would you think it acceptable to do anything less for yourself?
  • You need to know who you are, so that you understand your armament and bolster yourself in respect to your limitations. You need to know where you are going, so that you can limit the extent of chaos in your life, restructure order, and bring the divine force of Hope to bear on the world.
  • You need to determine how to act toward yourself so that you are most likely to become and to stay a good person.
  • Don’t underestimate the power of vision and direction. These are irresistible forces, able to transform what might appear to be unconquerable obstacles into traversable pathways and expanding opportunities.
  • Once having understood Hell, researched it, so to speak—particularly your
  • own individual Hell—you could decide against going there or creating that.
  • You could, in fact, devote your life to this. That would give you a Meaning, with a capital M. That would justify your miserable existence.
  • That would atone for your sinful nature, and replace your shame and self-consciousness with the natural pride and forthright confidence of someone who has learned once again to walk with God in the Garden.
  • RULE 3   MAKE FRIENDS WITH PEOPLE WHO WANT THE BEST FOR YOU
  • It would be more romantic, I suppose, to suggest that we would have all jumped at the chance for something more productive, bored out of our skulls as we were. But it’s not true. We were all too prematurely cynical and world-weary and leery of responsibility to stick to the debating clubs and Air Cadets and school sports that the adults around us tried to organize. Doing anything wasn’t cool.
  • When you move, everything is up in the air, at least for a while. It’s stressful, but in the chaos there are new possibilities. People, including you, can’t hem you in with their old notions. You get shaken out of your ruts. You can make new, better ruts, with people aiming at better things. I thought this was just a natural development. I thought that every person who moved would have—and want—the same phoenix-like experience.
  • What was it that made Chris and Carl and Ed unable (or, worse, perhaps, unwilling) to move or to change their friendships and improve the circumstances of their lives? Was it inevitable—a consequence of their own limitations, nascent illnesses and traumas of the past?
  • Why did he—like his cousin, like my other friends—continually choose people who, and places that, were not good for him?
  • perhaps, they don’t want the trouble of better. Freud called this a “repetition compulsion.” He thought of it as an unconscious drive to repeat the horrors of the past
  • People create their worlds with the tools they have directly at hand. Faulty tools produce faulty results. Repeated use of the same faulty tools produces the same faulty results.
  • It is in this manner that those who fail to learn from the past doom themselves to repeat it. It’s partly fate. It’s partly inability. It’s partly…unwillingness to learn? Refusal to learn? Motivated refusal to learn?
  • People choose friends who aren’t good for them for other reasons, too. Sometimes it’s because they want to rescue someone.
  • it is not easy to distinguish between someone truly wanting and needing help and someone who is merely exploiting a willing helper. The distinction is difficult even for the person who is wanting and needing and possibly exploiting.
  • When it’s not just naïveté, the attempt to rescue someone is often fuelled by vanity and narcissism.
  • But Christ himself, you might object, befriended tax-collectors and prostitutes. How dare I cast aspersions on the motives of those who are trying to help? But Christ was the archetypal perfect man. And you’re you.
  • How do you know that your attempts to pull someone up won’t instead bring them—or you—further down?
  • The same thing happens when well-meaning counsellors place a delinquent teen among comparatively civilized peers. The delinquency spreads, not the stability.65 Down is a lot easier than up.
  • maybe you’re saving someone because you want to convince yourself that the strength of your character is more than just a side effect of your luck and birthplace. Or maybe it’s because it’s easier to look virtuous when standing alongside someone utterly irresponsible.
  • Or maybe you have no plan, genuine or otherwise, to rescue anybody. You’re associating with people who are bad for you not because it’s better for anyone, but because it’s easier.
  • You know it. Your friends know it. You’re all bound by an implicit contract—one aimed at nihilism, and failure, and suffering of the stupidest sort.
  • Before you help someone, you should find out why that person is in trouble. You shouldn’t merely assume that he or she is a noble victim of unjust circumstances and exploitation. It’s the most unlikely explanation, not the most probable.
  • Besides, if you buy the story that everything terrible just happened on its own, with no personal responsibility on the part of the victim, you deny that person all agency in the past (and, by implication, in the present and future, as well).
  • It is far more likely that a given individual has just decided to reject the path upward, because of its difficulty. Perhaps that should even be your default assumption, when faced with such a situation.
  • failure is easy to understand. No explanation for its existence is required. In the same manner, fear, hatred, addiction, promiscuity, betrayal and deception require no explanation. It’s not the existence of vice, or the indulgence in it, that requires explanation. Vice is easy.
  • Failure is easy, too. It’s easier not to shoulder a burden. It’s easier not to think, and not to do, and not to care. It’s easier to put off until tomorrow what needs to be done today,
  • Success: that’s the mystery. Virtue: that’s what’s inexplicable. To fail, you merely have to cultivate a few bad habits. You just have to bide your time. And once someone has spent enough time cultivating bad habits and biding their time, they are much diminished.
  • I am not saying that there is no hope of redemption. But it is much harder to extract someone
  • from a chasm than to lift him from a ditch. And some chasms are very deep. And there’s not much left of the body at the bottom.
  • Carl Rogers, the famous humanistic psychologist, believed it was impossible to start a therapeutic relationship if the person seeking help did not want to improve.67 Rogers believed it was impossible to convince someone to change for the better. The
  • none of this is a justification for abandoning those in real need to pursue your narrow, blind ambition, in case it has to be said.
  • Here’s something to consider: If you have a friend whose friendship you wouldn’t recommend to your sister, or your father, or your son, why would you have such a friend for yourself?
  • You are not morally obliged to support someone who is making the world a worse place. Quite the opposite. You should choose people who want things to be better, not worse. It’s a good thing, not a selfish thing, to choose people who are good for you.
  • It is for this reason that every good example is a fateful challenge, and every hero, a judge. Michelangelo’s great perfect marble David cries out to its observer: “You could be more than you are.”
  • Don’t think that it is easier to surround yourself with good healthy people than with bad unhealthy people. It’s not. A good, healthy person is an ideal. It requires strength and daring to stand up near such a person.
  • RULE 4   COMPARE YOURSELF TO WHO YOU WERE YESTERDAY, NOT TO WHO SOMEONE ELSE IS TODAY
  • IT WAS EASIER FOR PEOPLE to be good at something when more of us lived in small, rural communities. Someone could be homecoming queen. Someone else could be spelling-bee champ, math whiz or basketball star. There were only one or two mechanics and a couple of teachers. In each of their domains, these local heroes had the opportunity to enjoy the serotonin-fuelled confidence of the victor.
  • Our hierarchies of accomplishment are now dizzyingly vertical.
  • No matter how good you are at something, or how you rank your accomplishments, there is someone out there who makes you look incompetent.
  • We are not equal in ability or outcome, and never will be. A very small number of people produce very much of everything.
  • People are unhappy at the bottom. They get sick there, and remain unknown and unloved. They waste their lives there. They die there. In consequence, the self-denigrating voice in the minds of people weaves a devastating tale. Life is a zero-sum game. Worthlessness is the default condition.
  • It is for such reasons that a whole generation of social psychologists recommended “positive illusions” as the only reliable route to mental health.69 Their credo? Let a lie be your umbrella. A more dismal, wretched, pessimistic philosophy can hardly be imagined:
  • Here is an alternative approach (and one that requires no illusions). If the cards are always stacked against you, perhaps the game you are playing is somehow rigged (perhaps by you, unbeknownst to yourself). If the internal voice makes you doubt the value of your endeavours—or your life, or life itself—perhaps you should stop listening.
  • There will always be people better than you—that’s a cliché of nihilism, like the phrase, In a million years, who’s going to know the difference? The proper response to that statement is not, Well, then, everything is meaningless. It’s, Any idiot can choose a frame of time within which nothing matters.
  • Standards of better or worse are not illusory or unnecessary. If you hadn’t decided that what you are doing right now was better than the alternatives, you wouldn’t be doing it. The idea of a value-free choice is a contradiction in terms. Value judgments are a precondition for action.
  • Furthermore, every activity, once chosen, comes with its own internal standards of accomplishment. If something can be done at all, it can be done better or worse. To do anything at all is therefore to play a game with a defined and valued end, which can always be reached more or less efficiently and elegantly.
  • We might start by considering the all-too-black-and-white words themselves: “success” or “failure.” You are either a success, a comprehensive, singular, over-all good thing, or its opposite, a failure, a comprehensive, singular, irredeemably bad thing.
  • There are vital degrees and gradations of value obliterated by this binary system, and the consequences are not good.
  • there is not just one game at which to succeed or fail. There are many games and, more specifically, many good games—
  • if changing games does not work, you can invent a new one. I
  • and athletic pursuits. You might consider judging your success across all the games you play.
  • When we are very young we are neither individual nor informed. We have not had the time nor gained the wisdom to develop our own standards. In consequence, we must compare ourselves to others, because standards are necessary.
  • As we mature we become, by contrast, increasingly individual and unique. The conditions of our lives become more and more personal and less and less comparable with those of others. Symbolically speaking, this means we must leave the house ruled by our father, and confront the chaos of our individual Being.
  • We must then rediscover the values of our culture—veiled from us by our ignorance, hidden in the dusty treasure-trove of the past—rescue them, and integrate them into our own lives. This is what gives existence its full and necessary meaning.
  • What is it that you actually love? What is it that you genuinely want? Before you can articulate your own standards of value, you must see yourself as a stranger—and then you must get to know yourself. What
  • Dare to be truthful. Dare to articulate yourself, and express (or at least become aware of) what would really justify your life.
  • Consult your resentment. It’s a revelatory emotion, for all its pathology. It’s part of an evil triad: arrogance, deceit, and resentment. Nothing causes more harm than this underworld Trinity. But resentment always means one of two things. Either the resentful person is immature, in which case he or she should shut up, quit whining, and get on with it, or there is tyranny afoot—in which case the person subjugated has a moral obligation to speak up.
  • Be cautious when you’re comparing yourself to others. You’re a singular being, once you’re an adult. You have your own particular, specific problems—financial, intimate, psychological, and otherwise.
  • Those are embedded in the unique broader context of your existence. Your career or job works for you in a personal manner, or it does not, and it does so in a unique interplay with the other specifics of your life.
  • We must see, but to see, we must aim, so we are always aiming. Our minds are built on the hunting-and-gathering platforms of our bodies. To hunt is to specify a target, track it, and throw at it.
  • We live within a framework that defines the present as eternally lacking and the future as eternally better. If we did not see things this way, we would not act at all. We wouldn’t even be able to see, because to see we must focus, and to focus we must pick one thing above all else on which to focus.
  • The disadvantage to all this foresight and creativity is chronic unease and discomfort. Because we always contrast what is with what could be, we have to aim at what could be.
  • The present is eternally flawed. But where you start might not be as important as the direction you are heading. Perhaps happiness is always to be found in the journey uphill, and not in the fleeting sense of satisfaction awaiting at the next peak.
  • Called upon properly, the internal critic will suggest something to set in order, which you could set in order, which you would set in order—voluntarily, without resentment, even with pleasure.
  • “Excuse me,” you might say to yourself, without irony or sarcasm. “I’m trying to reduce some of the unnecessary suffering around here. I could use some help.” Keep the derision at bay. “I’m wondering if there is anything that you would be willing to do? I’d be very grateful for your service.” Ask honestly and with humility. That’s no simple matter.

  • Myth 2: ‘Being overweight isn’t that bad for you’
  • Analysis from 2013 investigated the long-term consequences of obesity with the specific aim of examining so-called “healthily obese” people. A comparison between healthy people of normal weight and healthy but obese subjects showed the latter group had a significantly higher risk of dying or developing cardiovascular disease. The scientists who carried out the study therefore came to the conclusion that the belief you can be “fat but fit” is just a myth.
  • A 2015 study confirmed those results. It followed supposedly healthily obese subjects over 20 years and found that more than half became unhealthily obese during that time. Their risk of becoming ill was eight times higher than that of the healthy group with normal weight. The risks include, but are not limited to: diabetes, cardiovascular disease, cancer, sleep apnoea, arthritis/joint problems, fertility problems, asthma, back pain, incontinence, gout and stroke.

  • Myth 3: ‘Being overweight doesn’t impede me’
  • Myth 4: ‘My family and friends don’t think I need to lose weight’
  • Myth 5: ‘Obesity is largely due to your genes’
  • Genes create a basic situation, but they don’t oblige anyone to be fat. Things that can genuinely be explained by genetics are appetite, preferences for certain flavours (such as sweet or fatty) and the natural urge to be physically active.
  • Several studies have shown that carriers of so-called obesity genes consume on average 125-280 kcal a day more and have no differences in their metabolic rates. To say that some children have a genetic propensity towards obesity means only that they have an inherently larger appetite than naturally slim children, who feel hungry less often.
  • But the deciding factor in whether children have a tendency towards being fat is the set of conditions created by their parents and the rest of their environment (such as school meals), which can serve either to encourage or discourage obesity.
  • Living in a household where high-calorie food is constantly available won’t necessarily make children fat if their genetics mean they have a naturally small appetite. Children with naturally large appetites, by contrast, will pounce on the proffered fare.
  • However, studies have shown that food preferences are not an inescapable fate
  • In the end, our genes just set out the path we will follow if we don’t actively strive to change its direction (which can take great effort). However, those efforts are only temporary: once we have become habituated to new behaviours, we no longer have to struggle to maintain them.

  • Last year, some 41,354 Americans received a transplanted organ, more than half of them receiving kidneys,
  • But there is an acute shortage of organs, and about a dozen people on the lists die each day. Some 3,817 Americans received human donor hearts last year as replacements, more than ever before, but the potential demand is still higher.
  • Researchers hope procedures like this will usher in a new era in medicine in the future when replacement organs are no longer in short supply for the more than half a million Americans who are waiting for kidneys and other organs.
  • He is also being monitored for infections, including porcine retrovirus, a pig virus that may be transmitted to humans, although the risk is considered low.
  • But he added that there were many hurdles to overcome before such a procedure could be broadly applied, noting that rejection of organs occurs even when a well-matched human donor kidney is transplanted.

  • Mr. Bennett decided to gamble on the experimental treatment because he would have died without a new heart, had exhausted other treatments and was too sick to qualify for a human donor heart, family members and doctors said.
  • Mr. Bennett is still connected to a heart-lung bypass machine, which was keeping him alive before the operation, but that is not unusual for a new heart transplant recipient, experts said.
  • The new heart is functioning and already doing most of the work, and his doctors said he could be taken off the machine on Tuesday. Mr. Bennett is being closely monitored for signs that his body is rejecting the new organ, but the first 48 hours, which are critical, passed without incident.

  • Xenotransplantation, the process of grafting or transplanting organs or tissues from animals to humans, has a long history. Efforts to use the blood and skin of animals go back hundreds of years.
  • In the 1960s, chimpanzee kidneys were transplanted into some human patients, but the longest a recipient lived was nine months.
  • In 1983, a baboon heart was transplanted into an infant known as Baby Fae, but she died 20 days later.
  • Two newer technologies — gene editing and cloning — have yielded genetically altered pig organs less likely to be rejected by humans.

  • The heart transplanted into Mr. Bennett came from a genetically altered pig provided by Revivicor, a regenerative medicine company based in Blacksburg, Va.
  • The pig had 10 genetic modifications. Four genes were knocked out, or inactivated, including one that encodes a molecule that causes an aggressive human rejection response.
  • A growth gene was also inactivated to prevent the pig’s heart from continuing to grow after it was implanted,
  • In addition, six human genes were inserted into the genome of the donor pig — modifications designed to make the porcine organs more tolerable to the human immune system.
  • The team used a new experimental drug developed in part by Dr. Mohiuddin and made by Kiniksa Pharmaceuticals to suppress the immune system and prevent rejection.
  • “The anatomy was a little squirrelly, and we had a few moments of ‘uh-oh’ and had to do some clever plastic surgery to make everything fit,”
  • “the heart fired right up” and “the animal heart began to squeeze.”
  • He said his father had had a pig’s valve inserted about a decade ago, and he thought his father might be confused. But after a while, Mr. Bennett said, “I realized, ‘Man, he is telling the truth and not going crazy. And he could be the first ever.’”

  • t's seems the height of arrogance for any paleoanthropologist to assume that the bones they have in hand represent all knowledge. That what is certainly the vast majority of still-existing bones and materials still hidden in earth doesn't represent anything they they don't already know from the relative scraps they have found.
  • On the other hand, the geneticists don't have "evidence", they have hints or suggestions. Sure, they can see existing genes in a modern DNA sampling that have similarities to genes from an older sampling dug from the earth, but how those genes came to be in the modern specimen is completely assumptive guesswork. The geneticists are looking at two end points and are 1. assuming they are of the same linear history and then 2. are assuming all the points in between. Rather grand assumptions.

  • The real problem is in how information is obtained. Anthropologists study bones and are forced to draw conclusions based on ancient, fragmentary evidence, and geneticists can obtain complete DNA samples, but not of very ancient organisms. Both are forced to make assumptions based on different sources of evidence. With regard to the accepted tree of life (much as a bridge lacking most of the cables or roadway) it's very much a work in progress!

  • researchers have determined virtually the entire genome of a fetus using only a blood sample from the pregnant woman and a saliva specimen from the father
  • That would allow thousands of genetic diseases to be detected prenatally. But the ability to know so much about an unborn child is likely to raise serious ethical considerations as well. It could increase abortions for reasons that have little to do with medical issues and more to do with parental preferences for traits in children.
  • The process is not practical, affordable or accurate enough for use now, experts said. The University of Washington researchers estimated that it would cost $20,000 to $50,000 to do one fetal genome today. But the cost of DNA sequencing is falling at a blistering pace, and accuracy is improving as well. The researchers estimated that the procedure could be widely available in three to five years. Others said it would take somewhat longer.

  • U.S. health regulators on Thursday cleared the way for a type of genetically engineered Atlantic salmon to be farmed for human consumption - the first such approval for an animal whose DNA has been scientifically modified.
  • Five years ago, the U.S. Food and Drug Administration first declared the product, made by Massachusetts-based AquaBounty Technologies, to be as safe as conventional farm-raised Atlantic salmon.
  • AquaBounty's product will not require special labeling because it is nutritionally equivalent to conventional farm-raised Atlantic salmon, the FDA said on Thursday.

  • AquaBounty developed the salmon by altering its genes so that it would grow faster than farmed salmon, and expects it will take about two more years to reach consumers' plates as it works out distribution.
  • AquaBounty says its salmon can grow to market size in half the time of conventional salmon, saving time and resources. The fish is essentially Atlantic salmon with a Pacific salmon gene for faster growth and a gene from the eel-like ocean pout that promotes year-round growth.
  • Activist groups have expressed concerns that genetically modified foods may pose risks to the environment or public health.
  • Kroger Co, the nation’s largest traditional grocery chain, has “no intention of sourcing or selling genetically engineered salmon,” spokesman Keith Dailey said. Trader Joe's and Whole Foods Market Inc also confirmed that they do not intend to carry the product.
  • Target Corp eliminated farm-raised salmon in favor of wild-caught salmon in 2010, which spokeswoman Molly Snyder said was the first step in a long-term commitment to improving the sustainability of our seafood assortment. "

History genomics evolution demographics archaeology molecular

  • Who Killed the Men of England? The written record of history meets genomics, evolution, demography, and molecular archaeology.
  • more than a million men vanished without a trace. They left no descendants. Historians know that something dramatic happened in England just as the Roman empire was collapsing. When the Anglo-Saxons first arrived in that northern outpost in the fourth century a.d.--whether as immigrants or invaders is debated--they encountered an existing Romano-Celtic population estimated at between 2 million and 3.7 million people. Latin and Celtic were the dominant languages.
  • Yet the ensuing cultural transformation was so complete, says Goelet professor of medieval history Michael McCormick, that by the eighth century, English civilization considered itself completely Anglo-Saxon, spoke only Anglo-Saxon, and thought that everyone had “come over on the Mayflower, as it were.”
  • ...23 more annotations...
  • Working along an east-west transect through central England and Wales, the scientists discovered that the mix of Y-chromosomes characteristic of men in the English towns was very different from that of men in the Welsh towns: Wales was the primary Celtic holdout in Western Britannia during the ascendance of the Anglo-Saxons. Using computer analysis, the researchers explored how such a pattern could have arisen and concluded that a massive replacement of the native fourth-century male Britons had taken place. Between 50 percent and 100 percent of indigenous English men today, the researchers estimate, are descended from Anglo-Saxons who arrived on England’s eastern coast 16 centuries ago.
  • So what happened? Mass killing, or “population replacement,” is one possible explanation. Mass migration of Anglo-Saxons, so that they swamped the native gene pool, is another.
  • Yet no archaeological or historical evidence from the fifth and sixth centuries hints at the immense scale of violence or migration that would be necessary to explain this genetic legacy. The science hinted at an untold story.
  • across entire fields of inquiry, the traditional boundaries between history and prehistory have been melting away as the study of the human past based on the written record increasingly incorporates the material record of the natural and physical sciences.
  • The study of the human past, in other words, has entered a new phase in which science has begun to tell stories that were once the sole domain of humanists.
  • Thomas had found that genetically, not one of the English towns he sampled was significantly different from the others. Welsh towns, on the other hand, were significantly different from each other and from the English towns.
  • Most importantly, he found that inhabitants of  the Dutch province of Friesland were indistinguishable genetically from the English town-dwellers. Friesland is one of the known embarkation points of the Angl0-Saxons--and the language spoken there is the closest living relative to English.
  • The implications are profound: “Suddenly, we have all these genuine historical observations that need to be taken on board by historians and archaeologists and they raise a whole series of new questions, focusing particularly on…what is going on at the intimate level of this new civilization that is being born in the ruins of the Roman empire. The history of Europe will never be the same.”
  • But most archaeologists and historians who understand the economic capacity of the era, he noted, “find such massive contributions to the English gene pool to be completely unacceptable.
  • “But still, the genetic data are quite robust,” Thomas pointed out. “This is where the idea of an apartheid-like social structure comes in.” He has advanced a theory that a sexually biased, ethnically driven reproductive pattern, in which Anglo-Saxon males fathered children with Anglo-Saxon females and possibly Celtic females, while the reproductive activities of Romano-Celtic males were more restricted, is the most plausible explanation for the demographic, archaeological, and genetic patterns seen today. 
  • In an attempt to explain the remarkable similarity between Frisian and English towns, Thomas and colleagues constructed a population simulation model on a computer. He tested many theories: common ancestry dating back to the Neolithic age; background migration over centuries and even millennia; and a mass-migration event that, he calculated, would have had to involve at least 50 percent replacement--the movement, in other words, of a million people.
  • Simulating such an advantage, and choosing an arbitrary figure of 10 percent migration, Thomas found that the Y chromosomes of native Britons could have been replaced in the general population in as few as five generations. 
  • by the 1970s, he continues, scholars began to realize there never was a homogenous “nation” of Germans in northern Europe, just small tribes that coalesced along the Roman frontier in what were political and cultural, rather than biological, federations, as their very names suggest: Alemanni, meaning “all men”; Goths, meaning “good guys.”
  • The Romans, scholars believed, provided a common enemy, and that unified the disparate Germanic tribes. This line of reasoning led historians to a further thought: maybe the Anglo-Saxon identity was similarly socially constructed, and not biological after all
  • More recent historical scholarship, therefore, has increasingly emphasized discovering the extent to which the barbarian migrations were really a process of ethnogenesis--the creation of new ethnic identities, as the merchant’s story illustrates.
  • “There is lots of evidence for it,” McCormick says. “But now you have Mark Thomas telling us that you could actually study mating patterns. That is utterly unanticipated.” The work raises a host of new questions: What was women’s role in the barbarian settlements? Were Anglo-Saxon men mating with Celtic women? Or were there women in those invading boats, and if so, how many? What happened to the Romano-Celtic men? Were they killed? 
  • There is some support for this in ancient English laws, which indicate that Britons and Anglo-Saxons were legally and economically different even in the seventh century, long after the initial migration. Thomas cited wergild (blood money) payments as one example: “Killing an Anglo-Saxon was a costly business, but killing a native Briton was quite cheap.” This points to differences in economic status. And differences in wealth “almost always result in differences in reproductive output,” he said. “Sometimes two- and three-fold differences.” To the extent Anglo-Saxons were able to have and support more children, this could lead to a gradual replacement of the indigenous Y-chromosome over many generations
  • The Y-chromosome can be a particularly revealing signature of the past when compared to other kinds of genetic data. Among African Americans in the United States, for example, Y-chromosomes are about 33 percent European, he says, though the proportion varies from city to city. But those same African Americans’ mitochondrial DNA, which comes from the female line, is only about 6 percent European. And that, says Reich, “tells you about the history of this country, in which men contributed about three-fourths of the European ancestry that is present in the African-American population data. The data speak to a history in which white male slaveowners exploited women of African descent--a fact that is well documented in the historical record. That there is evidence of this in genetic data should be no surprise.”
  • Most Americans associate Medellín with the drug cartels of that isolated region. But the remoteness has also preserved a genetic legacy that can be traced to the conquistadores. As described in a paper by Andrés Ruiz-Linares of University College London, the Y-chromosomes of men in Medellín are 95 percent European, while the mitochondrial DNA of the women is 95 percent Native American. Spanish men and Native American women created a new population--confirming the recorded history of the region.
  • The pattern of sexual exploitation by a dominant group seen in the preceding examples is not at all unusual in the human genetic record, says Reich’s frequent collaborator, Nick Patterson, a senior research scientist at the Broad Institute of MIT and Harvard. The Icelandic sagas record that the exiles who settled that island raided Scotland and Ireland, kidnapping Celtic women. And the genes corroborate this account. The mitochondrial DNA of the women is Celtic, the Y-chromosomes are Nordic
  • Fortunately, the science of the human past has progressed in these other areas no less than in the field of genetics. Innovations in archaeological analysis have had a profound impact
  • After the fall of the Roman empire, “you get this layer called ‘dark earth’” in the archaeological stratigraphy, he says. “People thought the empire fell and the cities turned into garden [plots]. That is how dark earth was understood up until about five years ago,
  • “In the Roman excavations,” says McCormick, “there were pots and stone buildings and columns.” But then suddenly you get a layer of nothing but dark, humus-looking soil. What actually happened, Galinié and others have found, is that people shifted to organic building materials. “They had thatched roofs and wooden houses, they didn’t have Roman garbage removal, and they just dumped the ashes and charcoal from their hearths out in the road and all of that compacted. It is extremely rich, extremely dense,

  • Arun Durvasula and Sankararaman obtained 405 genomes from four west African populations and used statistical techniques to work out whether an influx of genes from interbreeding was likely to have happened in the distant past. The analysis suggested that it had in every case.
  • The scientists went on to scour the African genomes for chunks of DNA that looked different to modern human genes. This allowed them to pull out sequences that most probably came from an ancient relative. By comparing these with genes from Neanderthals and Denisovans, they concluded that the DNA had to come from an unknown group of archaic humans.
  • “They seem to have made a pretty substantial impact on the genomes of the present day individuals we studied,” Sankararaman said. “They account for 2% to 19% of their genetic ancestry.” The four populations studied came from three countries: two from Nigeria, and one each from Sierra Leone and the Gambia.
