The Invention of Childhood, or Why It Hurts to Have a Baby [Excerpt] - 0 views

  • It’s impossible to overstate the colossal impact this turn of events had on our evolution, but it requires some context to fully appreciate what it means. Our habit of being born early is part of a larger, stranger phenomenon that scientists call neoteny, a term that covers a lot of evolutionary sins at the same time it explains so much of what makes us the unique, even bizarre creatures we are.
  • you might think that neoteny is simply a matter of a species holding on to as many youthful traits of an ancestor as long into adulthood as possible
  • And our brain development is anything but arrested. In fact, just the opposite. As I said, complicated.
  • ...19 more annotations...
  • The different ways some parts of us seem to accelerate and mature while others bide their time or halt altogether has generated a flock of terms related to neoteny—paedomorphosis, heterochrony, progenesis, hypermorphosis, and recapitulation.
  • In the end, however, it comes down to this—each represents an evolution of evolution itself, an exceptional and rare combination of adaptations that changed our ancestors so fundamentally that it led to an ape (us) capable of changing the very planet that brought it into existence.5 Put another way, it changed everything.
  • Mostly we think of Darwin’s “descent by natural selection” as a chance transformation of newly arrived mutations—usually physical—into an asset rather than a liability, which is then passed along to the next generation.
  • But what neoteny (and paedomorphosis and all the rest) illustrate is that the forces of evolution don’t simply play with physical attributes, they play with time, too, or more accurately they can shift the times when genes are expressed and hormones flow, which not only alters looks but behavior, with fascinating results.
  • By being born “early,” our youth is amplified and elongated, and it continues to stretch out across our lives into the extended childhood that makes us so different from the other primates that preceded us.
  • All of the evidence emphatically points to our direct, gracile ape ancestors steadily extending their youth. They were inventing childhood.
  • Exactly how all of this unfolded on the wild and sprawling plains of Africa isn’t clear precisely, but there can be no doubt that it did. We stand as the indisputable proof.
  • The clustered neurons that together compose the brains of all primates grow at a rate before birth that even the most objective laboratory researcher could only call exuberant, maybe even scary.
  • Within a month of gestation primate brain cells are blooming by the thousands per second.
  • But for most species that growth slows markedly after birth. The brain of a monkey fetus, for example, arrives on its birthday with 70 percent of its cerebral development already behind it, and the remaining 30 percent is finished off in the next six months. A chimpanzee completes all of its brain growth within twelve months of birth.
  • You and I, however, came into the world with a brain that weighed a mere 23 percent of what it would become in adulthood.
  • even arriving in our early, fetal state, with less than a quarter of our brain development under our belts, we are still born with remarkably large brains.
  • this approach to brain development is so extraordinarily strange and rare that it is unique in nature.
  • evolution doesn’t plan. It simply modifies randomly and moves forward. And in this case, remember, remaining in the womb full term was out of the question. For us it was be born early, or don’t be born.
  • we simply haven’t yet gathered enough clues to know precisely when an early birth became unavoidable. There are, however, a few theories.
  • Some scientists believe earlier births would have begun when the adult brain of some predecessor or another reached 850 cc.
  • The lake, the streams and the rivers that fed it, and the variability of the weather made the area a kind of smorgasbord of biomes—grasslands, desert, verdant shorelines, clusters of forest and thick scrub. The bones of the extinct beasts that lie by the millions in the layers of volcanic ash beyond the shores of Lake Turkana today attest to its ancient popularity.
  • In fact it was so well liked that Homo ergaster, Homo habilis, and Homo rudolfensis were all ranging among its eastern and northern shores 1.8 million years ago
  • Viewed from either end of the spectrum, none of the clues about his age have made much sense to the teams of scientists who have labored over them. Each was out of sync with the other. Some life events were happening too soon, some too late, none strictly adhering to the growth schedules of either modern humans or forest apes. Still, the skeleton’s desynchronized features strongly suggested that the relatives of this denizen of Lake Turkana were almost certainly being born “younger,” elongating their childhoods and postponing their adolescence. Apes may be adolescents at age seven and humans at age eleven, but this creature fell somewhere in between.

Gut Microbes May Drive Evolution - 0 views

  • A 2010 experiment led by Eugene Rosenberg of Tel Aviv University found that raising Drosophila pseudoobscura fruit flies on different diets altered their mate selection: the flies would mate only with other flies on the same diet. A dose of antibiotics abolished these preferences—the flies went back to mating without regard to diet—suggesting that it was changes in gut microbes brought about by diet, and not diet alone, that drove the change.
  • These studies are part of a growing consensus among evolutionary biologists that one can no longer separate an organism's genes from those of its symbiotic bacteria. They are all part of a single "hologenome."
  • Researchers believe that the microbiome is essential to human evolution as well. "Given the importance of the microbiome in human adaptations such as digestion, smell and the immune system, it would appear very likely that the human microbiome has had an effect on speciation," Bordenstein says. "Arguably, the microbiota are as important as genes."
  •  
    "The human body harbors at least 10 times more bacterial cells than human cells. Collectively known as the microbiome, this community may play a role in regulating one's risk of obesity, asthma and allergies. Now some researchers are wondering if the microbiome may have a part in an even more crucial process: mate selection and, ultimately, evolution."

Evolution, Big Bang Polls Omitted From NSF Report - 0 views

  • In an unusual last-minute edit that has drawn flak from the White House and science educators, a federal advisory committee omitted data on Americans' knowledge of evolution and the big bang from a key report.
  • "Discussing American science literacy without mentioning evolution is intellectual malpractice" that "downplays the controversy" over teaching evolution in schools, says Joshua Rosenau of the National Center for Science Education, a nonprofit that has fought to keep creationism out of the science classroom. The story appears in this week's issue of Science.
  • Miller, the scientific literacy researcher, believes that removing the entire section was a clumsy attempt to hide a national embarrassment. "Nobody likes our infant death rate," he says by way of comparison, "but it doesn't go away if you quit talking about it."
  • ...2 more annotations...
  • The section, which was part of the unedited chapter on public attitudes toward science and technology, notes that 45% of Americans in 2008 answered true to the statement, "Human beings, as we know them today, developed from earlier species of animals."
  • The same gap exists for the response to a second statement, "The universe began with a big explosion," with which only 33% of Americans agreed.

A Brief History of the Corporation: 1600 to 2100 - 1 views

  • In its 400+ year history, the corporation has achieved extraordinary things, cutting around-the-world travel time from years to less than a day, putting a computer on every desk, a toilet in every home (nearly) and a cellphone within reach of every human.  It even put a man on the Moon and kinda-sorta cured AIDS.
  • The Age of Corporations is coming to an end. The traditional corporation won’t vanish, but it will cease to be the center of gravity of economic life in another generation or two.  They will live on as religious institutions do today, as weakened ghosts of more vital institutions from centuries ago.
  • this post is mostly woven around ideas drawn from five books that provide appropriate fuel for this business-first frame. I will be citing, quoting and otherwise indirectly using these books over several future posts
  • ...73 more annotations...
  • For a long time, I was misled by the fact that 90% of the available books frame globalization and the emergence of modernity in terms of the nation-state as the fundamental unit of analysis, with politics as the fundamental area of human activity that shapes things.
  • But the more I’ve thought about it, the more I’ve been pulled towards a business-first perspective on modernity and globalization.
  • The human world, like physics, can be reduced to four fundamental forces: culture, politics, war and business.
  • Culture is the most mysterious, illegible and powerful force.
  • But one quality makes gravity dominate at large space-time scales: gravity affects all masses and is always attractive, never repulsive.  So despite its weakness, it dominates things at sufficiently large scales. I don’t want to stretch the metaphor too far, but something similar holds true of business.
  • On the scale of days or weeks, culture, politics and war matter a lot more in shaping our daily lives.
  • Business though, as an expression of the force of unidirectional technological evolution, has a destabilizing unidirectional effect. It is technology, acting through business and Schumpeterian creative-destruction, that drives monotonic, historicist change, for good or bad. Business is the locus where the non-human force of technological change sneaks into the human sphere.
  • Culture is suspicious of technology. Politics is mostly indifferent to and above it. War-making uses it, but maintains an arms-length separation.
  • Business? It gets into bed with it. It is sort of vaguely plausible that you could switch artists, politicians and generals around with their peers from another age and still expect them to function. But there is no meaningful way for a businessman from (say) 2000 BC to comprehend what Mark Zuckerberg does, let alone take over for him. Too much magical technological water has flowed under the bridge.
  • It is business that creates the world of magic, not technology itself. And the story of business in the last 400 years is the story of the corporate form.
  • There are some who treat corporate forms as yet another technology (in this case a technology of people-management), but despite the trappings of scientific foundations (usually in psychology) and engineering synthesis (we speak of organizational “design”), the corporate form is not a technology.  It is the consequence of a social contract like the one that anchors nationhood. It is a codified bundle of quasi-religious beliefs externalized into an animate form that seeks to preserve itself like any other living creature.
  • What was new was the idea of a publicly traded joint-stock corporation, an entity with rights similar to those of states and individuals, with limited liability and significant autonomy
  • two important points about this evolution of corporations.
  • The first point is that the corporate form was born in the era of Mercantilism, the economic ideology that (zero-sum) control of land is the foundation of all economic power.
  • In politics, Mercantilism led to balance-of-power models.
  • In business, once the Age of Exploration (the 16th century) opened up the world, it led to mercantilist corporations focused on trade
  • The forces of radical technological change — the Industrial Revolution — did not seriously kick until after nearly 200 years of corporate evolution (1600-1800) in a mercantilist mold.
  • Smith was both the prophet of doom for the Mercantilist corporation, and the herald of what came to replace it: the Scumpeterian corporation.
  • The corporate form therefore spent almost 200 years — nearly half of its life to date — being shaped by Mercantilist thinking, a fundamentally zero-sum way of viewing the world.
  • It was not until after the American Civil War and the Gilded Age that businesses fundamentally reorganized around (as we will see) time instead of space, which led, as we will see, to a central role for ideas and therefore the innovation function.
  • The Black Hills Gold Rush of the 1870s, the focus of the Deadwood saga, was in a way the last hurrah of Mercantilist thinking. William Randolph Hearst, the son of gold mining mogul George Hearst who took over Deadwood in the 1870s, made his name with newspapers. The baton had formally been passed from mercantilists to schumpeterians.
    • anonymous
       
      So, Mercantilism was about colonizing space. Corporatism is about colonizing time. This is a pretty useful (though arguably too-reductionist) way to latch on to the underpinning of later thoughts.
  • This divide between the two models can be placed at around 1800, the nominal start date of the Industrial Revolution, as the ideas of Renaissance Science met the energy of coal to create a cocktail that would allow corporations to colonize time.
  • The second thing to understand about the evolution of the corporation is that the apogee of power did not coincide with the apogee of reach.
  • for America, corporations employed less than 20% of the population in 1780, and over 80% in 1980, and have been declining since
  • Certainly corporations today seem far more powerful than those of the 1700s, but the point is that the form is much weaker today, even though it has organized more of our lives. This is roughly the same as the distinction between fertility of women and population growth: the peak in fertility (a per-capita number) and peak in population growth rates (an aggregate) behave differently.
  • a useful 3-phase model of the history of the corporation: the Mercantilist/Smithian era from 1600-1800, the Industrial/Schumpeterian era from 1800 – 2000 and finally, the era we are entering, which I will dub the Information/Coasean era
    • anonymous
       
      I think it would be useful to map these eras against the backdrop of my previously established Generational timeline (as well as the StratFor 50-year cycle breakdown) in order to see if there are any self-supporting model elements.
  • By a happy accident, there is a major economist whose ideas help fingerprint the economic contours of our world: Ronald Coase.
  • To a large extent, the history of the first 200 years of corporate evolution is the history of the East India Company. And despite its name and nation of origin, to think of it as a corporation that helped Britain rule India is to entirely misunderstand the nature of the beast.
  • Two images hint at its actual globe-straddling, 10x-Walmart influence: the image of the Boston Tea Partiers dumping crates of tea into the sea during the American struggle for independence, and the image of smoky opium dens in China. One image symbolizes the rise of a new empire. The other marks the decline of an old one.
  • At a broader level, the EIC managed to balance an unbalanced trade equation between Europe and Asia whose solution had eluded even the Roman empire.
  • For this scheme to work, three foreground things and one background thing had to happen: the corporation had to effectively take over Bengal (and eventually all of India), Hong Kong (and eventually, all of China, indirectly) and England.
  • The background development was simpler. England had to take over the oceans and ensure the safe operations of the EIC.
  • eventually, as the threat from the Dutch was tamed, it became clear that the company actually had more firepower at its disposal than most of the nation-states it was dealing with. The realization led to the first big domino falling, in the corporate colonization of India, at the battle of Plassey.
  • The EIC was the original too-big-to-fail corporation. The EIC was the beneficiary of the original Big Bailout. Before there was TARP, there was the Tea Act of 1773 and the Pitt India Act of 1783. The former was a failed attempt to rein in the EIC, which cost Britain the American Colonies.  The latter created the British Raj as Britain doubled down in the east to recover from its losses in the west. An invisible thread connects the histories of India and America at this point. Lord Cornwallis, the loser at the Siege of Yorktown in 1781 during the revolutionary war, became the second Governor General of India in 1786.
  • But these events were set in motion over 30 years earlier, in the 1750s. There was no need for backroom subterfuge.  It was all out in the open because the corporation was such a new beast, nobody really understood the dangers it represented.
  • there was nothing preventing its officers like Clive from simultaneously holding political appointments that legitimized conflicts of interest. If you thought it was bad enough that Dick Cheney used to work for Halliburton before he took office, imagine if he’d worked there while in office, with legitimate authority to use his government power to favor his corporate employer and make as much money on the side as he wanted, and call in the Army and Navy to enforce his will. That picture gives you an idea of the position Robert Clive found himself in, in 1757.
  • The East India bubble was a turning point.
  • Over the next 70 years, political, military and economic power were gradually separated and modern checks and balances against corporate excess came into being.
  • It is not too much of a stretch to say that for at least a century and a half, England’s foreign policy was a dance in Europe in service of the EIC’s needs on the oceans.
  • Mahan’s book is the essential lens you need to understand the peculiar military conditions in the 17th and 18th centuries that made the birth of the corporation possible.)
  • The 16th century makes a vague sort of sense as the “Age of Exploration,” but it really makes a lot more sense as the startup/first-mover/early-adopter phase of the corporate mercantilism. The period was dominated by the daring pioneer spirit of Spain and Portugal, which together served as the Silicon Valley of Mercantilism. But the maritime business operations of Spain and Portugal turned out to be the MySpace and Friendster of Mercantilism: pioneers who could not capitalize on their early lead.
  • Conventionally, it is understood that the British and the Dutch were the ones who truly took over. But in reality, it was two corporations that took over: the EIC and the VOC (the Dutch East India Company,  Vereenigde Oost-Indische Compagnie, founded one year after the EIC) the Facebook and LinkedIn of Mercantile economics respectively. Both were fundamentally more independent of the nation states that had given birth to them than any business entities in history. The EIC more so than the VOC.  Both eventually became complex multi-national beasts.
  • arguably, the doings of the EIC and VOC on the water were more important than the pageantry on land.  Today the invisible web of container shipping serves as the bloodstream of the world. Its foundations were laid by the EIC.
    • anonymous
       
      There was an excellent episode of the original Connections series that pointed this out, specifically focusing on the Dutch boats and the direct line to container ships and 747 cargo planes.
  • A new idea began to take its place in the early 19th century: the Schumpeterian corporation that controlled, not trade routes, but time. It added the second of the two essential Druckerian functions to the corporation: innovation.
  • I call this the “most misleading table in the world.”
  • corporations and nations may have been running on Mercantilist logic, but the undercurrent of Schumpeterian growth was taking off in Europe as early as 1500 in the less organized sectors like agriculture. It was only formally recognized and tamed in the early 1800s, but the technology genie had escaped.
  • The action shifted to two huge wildcards in world affairs of the 1800s: the newly-born nation of America and the awakening giant in the east, Russia. Per capita productivity is about efficient use of human time. But time, unlike space, is not a collective and objective dimension of human experience. It is a private and subjective one. Two people cannot own the same piece of land, but they can own the same piece of time.  To own space, you control it by force of arms. To own time is to own attention. To own attention, it must first be freed up, one individual stream of consciousness at a time.
  • The Schumpeterian corporation was about colonizing individual minds. Ideas powered by essentially limitless fossil-fuel energy allowed it to actually pull it off.
  • it is probably reaosonably safe to treat the story of Schumpeterian growth as an essentially American story.
  • In many ways the railroads solved a vastly speeded up version of the problem solved by the EIC: complex coordination across a large area.  Unlike the EIC though, the railroads were built around the telegraph, rather than postal mail, as the communication system. The difference was like the difference between the nervous systems of invertebrates and vertebrates.
  • If the ship sailing the Indian Ocean ferrying tea, textiles, opium and spices was the star of the mercantilist era, the steam engine and steamboat opening up America were the stars of the Schumpeterian era.
  • The primary effect of steam was not that it helped colonize a new land, but that it started the colonization of time. First, social time was colonized. The anarchy of time zones across the vast expanse of America was first tamed by the railroads for the narrow purpose of maintaining train schedules, but ultimately, the tools that served to coordinate train schedules: the mechanical clock and time zones, served to colonize human minds.  An exhibit I saw recently at the Union Pacific Railroad Museum in Omaha clearly illustrates this crucial fragment of history:
  • For all its sophistication, the technology of sail was mostly a very-refined craft, not an engineering discipline based on science.
  • Steam power though was a scientific and engineering invention.
  • Scientific principles about gases, heat, thermodynamics and energy applied to practical ends, resulting in new artifacts. The disempowerment of craftsmen would continue through the Schumpeterian age, until Fredrick Taylor found ways to completely strip mine all craft out of the minds of craftsmen, and put it into machines and the minds of managers.
  • It sounds awful when I put it that way, and it was, in human terms, but there is no denying that the process was mostly inevitable and that the result was vastly better products.
  • The Schumpeterian corporation did to business what the doctrine of Blitzkrieg would do to warfare in 1939: move humans at the speed of technology instead of moving technology at the speed of humans.
  • Blitzeconomics allowed the global economy to roar ahead at 8% annual growth rates instead of the theoretical 0% average across the world for Mercantilist zero-sum economics. “Progress” had begun.
  • Two phrases were invented to name the phenomenon: productivity meant shrinking autonomously-owned time. Increased standard of living through time-saving devices became code for the fact that the “freed up” time through “labor saving” devices was actually the de facto property of corporations. It was a Faustian bargain.
  • Many people misunderstood the fundamental nature of Schumpeterian growth as being fueled by ideas rather than time. Ideas fueled by energy can free up time which can then partly be used to create more ideas to free up more time. It is a positive feedback cycle,  but with a limit. The fundamental scarce resource is time. There is only one Earth worth of space to colonize. Only one fossil-fuel store of energy to dig out. Only 24 hours per person per day to turn into capitive attention.
  • Then the Internet happened, and we discovered the ability to mine time as fast as it could be discovered in hidden pockets of attention. And we discovered limits. And suddenly a new peak started to loom: Peak Attention.
  • There is certainly plenty of energy all around (the Sun and the wind, to name two sources), but oil represents a particularly high-value kind. Attention behaves the same way.
  • Take an average housewife, the target of much time mining early in the 20th century. It was clear where her attention was directed. Laundry, cooking, walking to the well for water, cleaning, were all obvious attention sinks. Washing machines, kitchen appliances, plumbing and vacuum cleaners helped free up a lot of that attention, which was then immediately directed (as corporate-captive attention) to magazines and television.
  • The point isn’t that we are running out of attention. We are running out of the equivalent of oil: high-energy-concentration pockets of easily mined fuel.
  • There is a lot more money to be made in replacing hand-washing time with washing-machine plus magazine time, than there is to be found in replacing one hour of TV with a different hour of TV.
  • . To get to Clay Shirky’s hypothetical notion of cognitive surplus, we need Alternative Attention sources. To put it in terms of per-capita productivity gains, we hit a plateau.
  • When Asia hits Peak Attention (America is already past it, I believe), absolute size, rather than big productivity differentials, will again define the game, and the center of gravity of economic activity will shift to Asia.
  • Once again, it is the oceans, rather than land, that will become the theater for the next act of the human drama. While American lifestyle designers are fleeing to Bali, much bigger things are afoot in the region. And when that shift happens, the Schumpeterian corporation, the oil rig of human attention, will start to decline at an accelerating rate. Lifestyle businesses and other oddball contraptions — the solar panels and wind farms of attention economics — will start to take over.
  • It will be the dawn of the age of Coasean growth.
  • Coasean growth is not measured in terms of national GDP growth. That’s a Smithian/Mercantilist measure of growth. It is also not measured in terms of 8% returns on the global stock market.  That is a Schumpeterian growth measure. For that model of growth to continue would be a case of civilizational cancer (“growth for the sake of growth is the ideology of the cancer cell” as Edward Abbey put it).
  • Coasean growth is fundamentally not measured in aggregate terms at all. It is measured in individual terms. An individual’s income and productivity may both actually decline, with net growth in a Coasean sense.
  • How do we measure Coasean growth? I have no idea. I am open to suggestions. All I know is that the metric will need to be hyper-personalized and relative to individuals rather than countries, corporations or the global economy. There will be a meaningful notion of Venkat’s rate of Coasean growth, but no equivalent for larger entities.
  • The fundamental scarce resource that Coasean growth discovers and colonizes is neither space, nor time. It is perspective.
  •  
    This is a lay friendly, amateur, mental exploration of the Corporation. It's also utterly absorbing and comes with the usual collection of caveats that we amateurs are accustomed to rattling off when we dunk ourselves into issues much bigger than ourselves. Thanks to BoingBoing, via Futurismic, for the pointer: http://www.boingboing.net/2011/06/23/a-brief-history-of-t.html http://futurismic.com/2011/06/22/a-brief-history-of-the-corporation-1600-to-2100/ "The year was 1772, exactly 239 years ago today, the apogee of power for the corporation as a business construct. The company was the British East India company (EIC). The bubble that burst was the East India Bubble. Between the founding of the EIC in 1600 and the post-subprime world of 2011, the idea of the corporation was born, matured, over-extended, reined-in, refined, patched, updated, over-extended again, propped-up and finally widely declared to be obsolete. Between 2011 and 2100, it will decline - hopefully gracefully - into a well-behaved retiree on the economic scene."

Science-Based Medicine » It's a part of my paleo fantasy, it's a part of my p... - 0 views

  • If I had to pick one fallacy that rules above all among proponents of CAM/IM, it would have to be either the naturalistic fallacy (i.e., that if it’s natural—whatever that means—it must be better) or the fallacy of antiquity (i.e., that if it’s really old, it must be better).
  • Basically, it’s a rejection of modernity, and from it flow the interest in herbalism, various religious practices rebranded as treatments
  • there is a definite belief underlying much of CAM that technology and pharmaceuticals are automatically bad and that “natural” must be better.
  • ...33 more annotations...
  • it’s hard not to note that cancer and heart disease are primarily diseases of aging, and life expectancy was so much lower back in the day that a much smaller percentage of the population lived to advanced ages than is the case today.
  • Even so, an implicit assumption among many CAM advocates is that cardiovascular disease is largely a disease of modern lifestyle and diet and that, if modern humans could somehow mimic preindustrial or, according to some, even preagricultural, lifestyles, that cardiovascular disease could be avoided.
  • Over the last decade, Cordain has become the most prominent promoter of the so-called “Paleo diet,” having written The Paleo Diet: Lose Weight and Get Healthy by Eating the Foods You Were Designed to Eat and multiple other books advocating a paleolithic-mimetic diet as the cure for what ails modern humans.
  • But how does one determine what the prevalence of cardiovascular disease was in the ancient past?
  • there have been indications that the idea that ancient humans didn’t suffer from atherosclerosis is a comforting myth, the most recent of which is a study published a week ago online in The Lancet by Prof. Randall C. Thompson of Saint Luke’s Mid America Heart Institute and an international team of investigators entitled Atherosclerosis across 4000 years of human history: the Horus study of four ancient populations.
  • Basically, it was a study of 137 different mummies from four different geographic locations spanning 4,000 years.
  • So, although there was a fair amount of evidence from studies of Egyptian mummies that atherosclerosis was not uncommon, in Egypt it was mainly the wealthy and powerful who were mummified after their deaths. Conceivably, they could have lived a very different lifestyle and consumed a very different diet than the average Egyptian living around that time.
  • So the authors obtained whole-body CT scans of the 137 mummies, either pre-existing scans or scans prospectively done, and analyzed them for calcifications.
  • The mummies to be included in the study were chosen primarily based on two factors, being in a good state of preservation with identifiable vascular tissue, and being adults.
  • The authors obtained identifying information from an extensive search of museum and other databases by a team of archeologists and experts in mummy restoration, and sex was determined by either analysis of the genitals and reproductive organs when present and by pelvic morphology when they were not present.
  • Age was estimated by standard analysis of architectural changes in the clavicle, femur, and humerus.
  • Finally, multiple anthropological and archeological sources were used in an attempt to estimate likely risk factors for the mummies.
  • Figure 2 summarizes the findings nicely: There’s also this video featured in a Nature report on the study showing the reconstructed scan of one of the mummies with atherosclerotic plaques in the coronary arteries.
  • As expected, more atherosclerosis correlates with advanced age, and the amount of atherosclerosis in the young and middle-aged (although the times in which the people who became these mummies after death lived age 50 was old) was less.
  • Although the sample number was far too small to draw definitive conclusions (as is often the case in archeological research), the prevalence of atherosclerotic disease in these mummies did not appear to correlate with the cultures in which the mummies lived.
  • As is noted in Thompson’s article, ancient Egyptians and Peruvians were agricultural cultures with farms and domesticated animals, Ancestral Puebloans were forager-farmers, and the Unangans were hunter-gatherers without agriculture. Indeed, the Peruvians and Ancestral Puebloans predated the written word and were thus prehistoric cultures.
  • One notes that no one, including the authors of this study, is saying that lifestyle and diet are not important factors for the development of atherosclerotic heart disease.
  • What they are saying is that atherosclerosis appears to be associated with aging and that the claims that mimicking paleolithic diets (which, one notes, were definitely not vegan) are overblown. In other words, there is a certain inherent risk of atherosclerosis that is related to aging that is likely not possible to lower further
  • I actually think that the authors probably went too far with that last statement in that, while they might be correct that atherosclerosis is an inherent component of human aging, it is quite well established that this inherent component of aging can at least be worsened by sedentary lifestyle and probably certain diets.
  • One notes that, although the Paleo Diet is not, strictly speaking, always sold as CAM/IM, the ideas behind it are popular among CAM advocates, and the diet is frequently included as part of “integrative medicine,” for example, here at the University of Connecticut website, where it’s under integrative nutrition.
  • In particular, the appeal to ancient wisdom and ancient civilizations as yet untouched by the evil of modernity is the same sort of arguments that are made in favor of various CAM modalities ranging from herbalism to vegan diets rebranded as being somehow CAM to the appeal to “natural” cures.
  • Indeed, the fetish for the “natural” in CAM is such that even a treatment like Stanislaw Burzynski’s antineoplaston therapy is represented as “natural” when in fact, if it were ever shown to work against cancer, it would be chemotherapy and has toxicities greater than that of some of our current chemotherapy drugs.
  • The book is by Marlene Zuk and entitled Paleofantasy: What Evolution Really Tells Us About Sex, Diet, and How We Live. Zuk is an evolutionary biologist, and in particular she points out how the evolutionary arguments favored by advocates of the Paleo diet don’t stand up to scrutiny.
  • The interview begins with Zuk confronting Cordain at a conference on evolution and diseases of modern environments. At his lecture, Cordain pronounced several foods to be the cause of fatal conditions in people carrying certain genes.
  • These foods included, predictably, cultivated foods such as bread (made from grain), rice, and potatoes. Zuk couldn’t resist asking a question, namely why the inability to digest so many common foods would persist in the population, observing, “Surely it would have been selected out of the population.” Cordain’s response? That humans had not had time to adapt to these foods, to which Zuk retorted, “Plenty of time.” Apparently, in her book, Zuk produces numerous examples of evolution in humans occurring in a time frame of less than 10,000 years, including:
  • Blue eyes arose 6,000 to 10,000 years ago
  • Rapid selection for the CCR5-D gene variant that makes some people immune to HIV
  • Lactase persistence (production past the age of weening of the lactase enzyme that digests lactose in milk) probably dates back only around 7,500 to 10,000 years, around the time that cattle were domesticated
  • there is no one diet or climate that predominated among our Paleolithic ancestors:
  • Zuk detects an unspoken, barely formed assumption that humanity essentially stopped evolving in the Stone Age and that our bodies are “stuck” in a state that was perfectly adapted to survive in the paleolithic environment. Sometimes you hear that the intervention of “culture” has halted the process of natural selection. This, “Paleofantasy” points out, flies in the face of facts. Living things are always and continuously in the process of adapting to the changing conditions of their environment, and the emergence of lactase persistence indicates that culture (in this case, the practice of keeping livestock for meat and hides) simply becomes another one of those conditions.
  • For this reason, generalizations about the typical hunter-gatherer lifestyle are spurious; it doesn’t exist. With respect to what people ate (especially how much meat), the only safe assumption was “whatever they could get,” something that to this day varies greatly depending on where they live. Recently, researchers discovered evidence that people in Europe were grinding and cooking grain (a paleo-diet bugaboo) as far back as 30,000 years ago, even if they weren’t actually cultivating it. “A strong body of evidence,” Zuk writes, “points to many changes in our genome since humans spread across the planet and developed agriculture, making it difficult at best to point to a single way of eating to which we were, and remain, best suited.”
  • Oh, and, as Zuk tells us, paleolithic people got cancer, too.
  • we humans have long been known to abuse and despoil our environment, even back in those “paleo” days. Indeed, when I took a prehistoric archeology course, which was largely dedicated to the period of time of the hunter-gatherers, one thing I remember my professor pointing out, and that was that what he did was largely the study of prehistoric garbage and that humans have always produced a lot of it.

A New Thermodynamics Theory of the Origin of Life - 1 views

  • From the standpoint of physics, there is one essential difference between living things and inanimate clumps of carbon atoms: The former tend to be much better at capturing energy from their environment and dissipating that energy as heat.
  • Jeremy England, a 31-year-old assistant professor at the Massachusetts Institute of Technology, has derived a mathematical formula that he believes explains this capacity.
  • “You start with a random clump of atoms, and if you shine light on it for long enough, it should not be so surprising that you get a plant,” England said.
  • ...19 more annotations...
  • “I am certainly not saying that Darwinian ideas are wrong,” he explained. “On the contrary, I am just saying that from the perspective of the physics, you might call Darwinian evolution a special case of a more general phenomenon.”
  • The formula, based on established physics, indicates that when a group of atoms is driven by an external source of energy (like the sun or chemical fuel) and surrounded by a heat bath (like the ocean or atmosphere), it will often gradually restructure itself in order to dissipate increasingly more energy. This could mean that under certain conditions, matter inexorably acquires the key physical attribute associated with life.
  • His idea, detailed in a recent paper and further elaborated in a talk he is delivering at universities around the world, has sparked controversy among his colleagues, who see it as either tenuous or a potential breakthrough, or both.
  • Eugene Shakhnovich, a professor of chemistry, chemical biology and biophysics at Harvard University, are not convinced. “Jeremy’s ideas are interesting and potentially promising, but at this point are extremely speculative, especially as applied to life phenomena,” Shakhnovich said.
  • England’s theoretical results are generally considered valid. It is his interpretation — that his formula represents the driving force behind a class of phenomena in nature that includes life — that remains unproven. But already, there are ideas about how to test that interpretation in the lab.
  • “He’s trying something radically different,” said Mara Prentiss, a professor of physics at Harvard who is contemplating such an experiment after learning about England’s work. “As an organizing lens, I think he has a fabulous idea. Right or wrong, it’s going to be very much worth the investigation.”
  • At the heart of England’s idea is the second law of thermodynamics, also known as the law of increasing entropy or the “arrow of time.”
  • Hot things cool down, gas diffuses through air, eggs scramble but never spontaneously unscramble; in short, energy tends to disperse or spread out as time progresses.
  • It increases as a simple matter of probability: There are more ways for energy to be spread out than for it to be concentrated.
  • cup of coffee and the room it sits in become the same temperature, for example. As long as the cup and the room are left alone, this process is irreversible. The coffee never spontaneously heats up again because the odds are overwhelmingly stacked against so much of the room’s energy randomly concentrating in its atoms.
  • A plant, for example, absorbs extremely energetic sunlight, uses it to build sugars, and ejects infrared light, a much less concentrated form of energy. The overall entropy of the universe increases during photosynthesis as the sunlight dissipates, even as the plant prevents itself from decaying by maintaining an orderly internal structure.
  • Life does not violate the second law of thermodynamics, but until recently, physicists were unable to use thermodynamics to explain why it should arise in the first place.
  • In Schrödinger’s day, they could solve the equations of thermodynamics only for closed systems in equilibrium.
  • Jarzynski and Crooks showed that the entropy produced by a thermodynamic process, such as the cooling of a cup of coffee, corresponds to a simple ratio: the probability that the atoms will undergo that process divided by their probability of undergoing the reverse process (that is, spontaneously interacting in such a way that the coffee warms up).
  • Using Jarzynski and Crooks’ formulation, he derived a generalization of the second law of thermodynamics that holds for systems of particles with certain characteristics: The systems are strongly driven by an external energy source such as an electromagnetic wave, and they can dump heat into a surrounding bath.
  • This class of systems includes all living things.
  • Having an overarching principle of life and evolution would give researchers a broader perspective on the emergence of structure and function in living things, many of the researchers said. “Natural selection doesn’t explain certain characteristics,” said Ard Louis, a biophysicist at Oxford University, in an email. These characteristics include a heritable change to gene expression called methylation, increases in complexity in the absence of natural selection, and certain molecular changes Louis has recently studied.
  • If England’s approach stands up to more testing, it could further liberate biologists from seeking a Darwinian explanation for every adaptation and allow them to think more generally in terms of dissipation-driven organization.
  • They might find, for example, that “the reason that an organism shows characteristic X rather than Y may not be because X is more fit than Y, but because physical constraints make it easier for X to evolve than for Y to evolve,” Louis said.
  •  
    Why does life exist? Popular hypotheses credit a primordial soup, a bolt of lightning and a colossal stroke of luck. But if a provocative new theory is correct, luck may have little to do with it. Instead, according to the physicist proposing the idea, the origin and subsequent evolution of life follow from the fundamental laws of nature and "should be as unsurprising as rocks rolling downhill."

Evolution and Economics as Different Paradigms XI: Market Fundamentalism - 0 views

  • Of course, the fundamentalist beliefs of Rand and the Hutterites differ vastly in what they impel the believer to do.

Is ID Blasphemous? - 0 views

  • Modern evolutionary theory puts natural selection front and center, of course. It is precisely what those nineteenth century theologians most feared. On this point they were far closer in their thinking to modern creationists than they are to modern theistic evolutionists.
  • What are the central theological failings of intelligent design? First, it is blasphemous. Intelligent design constrains God to work within the limits of what its adherents can understand about nature. In so doing it reduces God from the status of creator to that of mere designer, and not a very competent one at that
  • It is not that they cannot allow that evolution is the process of creation chosen by God, it is that they have considered evolution and find it wanting.
  • ...6 more annotations...
  • Insisting on God as a cosmic designer -- who intervenes periodically to propel evolution in propitious directions -- inevitably lays the responsibility for the concomitant suffering squarely at the feet of the designer.
  • If intelligent design theory is correct, it is understandable why Richard Dawkins should describe God as being (among other things) a “sadomasochistic, capriciously malevolent bully.” To a theist, of course, such a description of God constitutes blasphemy, but this is the logical descriptor of the God of ``intelligent design,'' who ultimately is directly responsible for all the suffering built into a universe with which God interminably tinkers.
  • If you set in motion a process that inevitably leads to a bad outcome, you are as responsible for that outcome as if you caused it directly. If I drop an anvil from a balcony and it hits someone on the head I do not get to say, “I didn't do anything! It was a natural process, gravity, that did that.”
  • omehow, “evolution is exciting” does not seem like an adequate response to the billions of years of suffering, death and extinction entailed by the evolutionary process.
  • Hess is kidding himself if he thinks ID is a specifically evangelical Protestant phenomenon. If the public opinion polls are to be believed ID has widespread support among Catholics, Muslims and even orthodox Jews.
  • The Bible itself tells us that in contemplating nature people are “without excuse” for rejecting the existence of God. From the perspective of the Biblical writers, that God existed was regarded as something so obvious as to hardly be the sort of thing that needed proof.

Right by Accident: Science and Rational Ignorance - 0 views

  • That is because most Americans are not scientists or specialists in evolution, climatology, or any other scientific field. And if we treat scientific knowledge like any other area of specialized knowledge (politics, for example), then we know that the average person is likely to be rationally ignorant of science. As in politics, the average person will use ideology and rules-of-thumb, rather than the expert knowledge that they do not possess, to guide their behavior.

    "Conservatives have a bad reputation when it comes to science. Their case was not helped when Paul Broun, a Georgia Republican and member of the House Committee on Science, Space, and Technology, told a church group that he believes that, "evolution and embryology and the big bang theory, all that is lies straight from the pit of Hell." And then there was the news that educated conservatives have lost trust in science over the last 40 years. However, the debate on whether conservatives are better or worse than liberals on science obscures the fact that most people, liberal or conservative, tend to believe the science that suits their ideology. This means that either side being right or wrong on questions of science has more to do with chance than with actual scientific knowledge."

How Mitochondrial Eve connected all humanity and rewrote human evolution - 0 views

  • So how did Mitochondrial Eve manage to rewrite the entire story of human evolution? For that matter, what exactly is Mitochondrial Eve? Unlike her biblical namesake, she wasn't the only woman on Earth. In a sense, she's just a quirk of statistics. But if that's the case, then she's easily the most important quirk of statistics who ever lived.
  • In order to find a common ancestor whose genetics have passed on, we need to look for things that are passed down from generation to generation with little or no alteration. Both genders pass along one thing that is unchanged during sexual reproduction. For women, this is the mitochondrial DNA, which is a distinct subset of genetic material found not in the cell nucleus but rather in the mitochondria, the power plants of the cell.
  • By tracing the subtle mutations to mitochondrial DNA that have accumulated over the millennia, we can figure out which groups are most closely related, and ultimately fix the existence of Mitochondrial Eve to a fairly specific time in the past, which is currently estimated at about 200,000 years ago. That pretty much rules out the idea of multiple origins for humanity — otherwise Mitochondrial Eve would have to date back a couple million years, and mitochondrial analysis shows that that simply isn't the case.
  • ...1 more annotation...
  • While we don't really have 500 billion different ancestors, we can still look at the reverse of that idea: is there a single common ancestor that every person on Earth shares? As we know with Mitochondrial Eve, that answer is a resounding "yes" - but let's now take a look at the Most Recent Common Ancestor, or MRCA. The name says it all, really - this is simply the most recent person who, through any and all genetic lines, can be connected to every single person alive today.

Quitting the hominid fight club: The evidence is flimsy for innate chimpanzee--let alon... - 0 views

  • He asserts that both male humans and chimpanzees, our closest genetic relatives, are "natural warriors" with an innate predisposition toward "coalitionary killing," which dates back to our common ancestor.
  • "Chimpicide," Pinker wrote in his 2002 bestseller The Blank Slate the Modern Denial of Human Nature, "raises the possibility that the forces of evolution, not just the idiosyncrasies of a particular culture, prepared us for violence."
  • I've been reading and talking to anthropologists about the demonic-males theory for years, and I've turned from a believer to a skeptic. Here are some reasons why:
  • ...15 more annotations...
  • Mitani, for example, estimates the mortality rate from coalitionary attacks in Kibale to be as high as "2,790 per 100,000 individuals per year." But the researchers witnessed only 18 coalitionary killings. All told, since Jane Goodall began observing chimpanzees in Tanzania's Gombe National Park in 1960, researchers have directly observed 31 intergroup killings, of which 17 were infants.
  • In other words, researchers at a typical site directly observe one killing every seven years.
  • But that raises another question: Could unusual environmental conditions be triggering intergroup chimpanzee killing?
  • When we first offered the chimps bananas the males seldom fought over their food; …now…there was a great deal more fighting than ever before." (This quote appears in Sussman and Marshack's paper.)
  • Ian Tattersall, an anthropologist at the American Museum of Natural History, told me that chimpanzee violence is "plausibly related to population stress occasioned by human encroachment."
  • Researchers have never observed coalitionary killing among bonobos. Noting that bonobos are just as genetically related to us as chimpanzees, Frans de Waal, a primatologist at Emory University, suggested last year in The Wall Street Journal that bonobos may be "more representative of our primate background" than are chimpanzees.
  • One author, anthropologist Owen Lovejoy of Kent State University, told me that Ardi has triggered a "tectonic shift" in views of human evolution.
  • There is also no fossil or archaeological evidence that our ancestors fought millions or even hundreds of thousands of years ago. Yes, archaeological digs and modern ethnography have established that warfare was common among pre-state societies, notably hunter–gatherers; our ancestors are thought to have lived as hunter–gatherers since the emergence of the Homo genus two million years ago.
  • Advocates of the demonic-males thesis suggest that if hunter–gatherers ever engaged in warfare, they must have always done so.
  • But as the anthropologist Douglas Fry of Åbo Akademi University in Finland pointed out in his book Beyond War: The Human Potential for Peace (Oxford University Press, 2009), the oldest clear-cut relic of group violence is a 13,000-year-old grave along the Nile River in the Jebel Sahaba region of Sudan.
  • Evidence of earlier lethal human violence is ambiguous, at best.
  • But most Paleolithic injuries probably resulted from "hunting large animals who object to being speared," Trinkaus told me. "You find a lot of evidence of bumps and bruises and broken bones" among Neandertals and other early humans. "There is absolutely no evidence," Trinkaus says, that "war is continuous back to the common ancestor with chimps."
  • Advocates of the demonic-males thesis insist that absence of evidence of warfare does not equal evidence of absence, especially given the paucity of ancient human and prehuman remains.
  • These relics indicate that warfare arose as humans began shifting from "a nomadic existence to a sedentary one, commonly although not necessarily tied to agriculture," Ferguson says.
  • War's recent emergence, and its sporadic pattern, contradict the assertion of Wrangham and others that war springs from innate male tendencies, he argues. "If war is deeply rooted in our biology, then it's going to be there all the time. And it's just not," he says. War is certainly not as innate as language, a trait possessed by all known human societies at all times.

The Top Ten Daily Consequences of Having Evolved | Science & Nature | Smithsonian Magazine - 0 views

  • Perhaps a billion years ago, a single-celled organism arose that would ultimately give rise to all of the plants and animals on Earth, including us. This ancestor was the result of a merging: one cell swallowed, imperfectly, another cell.
  • Hiccups no longer serve a function, but they persist without causing us harm—aside from frustration and occasional embarrassment. One of the reasons it is so difficult to stop hiccupping is that the entire process is controlled by a part of our brain that evolved long before consciousness, and so try as you might, you cannot think hiccups away.

Five Billion Years of Solitude: Lee Billings on the Science of Reaching the Stars - 0 views

  • The question of habitability is a second-order consideration when it comes to Gliese 581g, and that fact in itself reveals where so much of this uncertainty comes from. As of right now, the most interesting thing about the "discovery" of Gliese 581g is that not everyone is convinced the planet actually exists. That's basically because this particular detection is very much indirect - the planet's existence is being inferred from periodic meter-per-second shifts in the position of its host star.
  • So it's very difficult to just detect these things, and actually determining whether they are much like Earth is a task orders of magnitude more difficult still. Notice how I'm being anthropocentric here: "much like Earth." Astrobiology has been derisively called a science without a subject. But, of course, it does have at least one subject: our own living planet and its containing solar system.
  • This is really a chicken-and-egg problem: To know the limits of life in planetary systems, we need to find life beyond the Earth. To find life beyond Earth, it would be very helpful to know the limits of life in planetary systems. Several independent groups are trying to circumvent this problem by studying abiogenesis in the lab - trying to in effect create life, alien or otherwise, in a test tube.
  • ...10 more annotations...
  • I do think humans are motivated to daydream about extraterrestrial intelligence, and, to put a finer point on it, extraterrestrial "people." They are motivated to dream about beings very much like them, things tantalizingly exotic but not so alien as to be totally incomprehensible and discomforting. Maybe those imagined beings have more appendages or sense organs, different body plans and surface coverings, but they typically possess qualities we recognize within ourselves: They are sentient, they have language, they use tools, they are curious explorers, they are biological, they are mortal - just like humans. Perhaps that's a collective failure of imagination, because it's certainly not very easy to envision intelligent aliens that are entirely divergent from our own anthropocentric preconceptions. Or perhaps it's more diagnostic of the human need for context, affirmation, and familiarity. Why are people fascinated by their distorted reflections in funhouse mirrors? Maybe it's because when they recognize their warped image, at a subconscious level that recognition reinforces their actual true appearance and identity.
  • More broadly, speculating about extraterrestrial intelligence is an extension of three timeless existential questions: What are we, where do we come from, and where are we going?
  • The first pessimistic take is that the differences between independently emerging and evolving biospheres would be so great as to prevent much meaningful communication occurring between them if any intelligent beings they generated somehow came into contact.
  • The second pessimistic take is that intelligent aliens, far from being incomprehensible and ineffable, would be in fact very much like us, due to trends of convergent evolution, the tendency of biology to shape species to fit into established environmental niches.
  • It stands to reason that any alien species that managed to embark on interstellar voyages to explore and colonize other planetary systems could, like us, be a product of competitive evolution that had effectively conquered its native biosphere. Their intentions would not necessarily be benevolent if they ever chose to visit our solar system.
  • The third pessimistic scenario is an extension of the second, and postulates that if we did encounter a vastly superior alien civilization, even if they were benevolent they could still do us harm through the simple stifling of human tendencies toward curiosity, ingenuity, and exploration.
  • Right now reaching low-Earth orbit generally comes at a cost somewhere between $5,000 to $10,000 per kilogram, depending on which launch vehicle is used. This creates an enormous barrier to making profitable ventures in space or building major space-based infrastructure. It also engenders further high costs in the design, fabrication, and testing of most spaceflight hardware, which due to the high cost to orbit must be made as lightweight and reliable as possible.
  • If launch costs fall well below $1,000 per kilogram, a host of economic activities that were previously prohibitively expensive should at a stroke become cheap enough to be readily profitable.
  • I'm an American citizen, so I will focus my comments on the American space program and the American political system. I'm sad to say that in this country, the most powerful nation presently on the planet, space science, exploration, and development are treated as fringe issues at best. Too many politicians, if they consider these issues at all, treat them in one of two ways: Dismissively, as things to be joked about, or cynically, as little more than pork-barrel job programs for their districts, things to be defended purely for the status quo and only given token lip-service when absolutely necessary.
  • And who can blame them? Look at what happens to politicians when they try to talk seriously and ambitiously about space today. They are lampooned and ridiculed by the media and by their political opponents as starry-eyed idealists who are disconnected from everyday realities.

Quantifying the consensus on anthropogenic global warming in the scientific literature - 0 views

  •  
    "We analyze the evolution of the scientific consensus on anthropogenic global warming (AGW) in the peer-reviewed scientific literature, examining 11 944 climate abstracts from 1991-2011 matching the topics 'global climate change' or 'global warming'. We find that 66.4% of abstracts expressed no position on AGW, 32.6% endorsed AGW, 0.7% rejected AGW and 0.3% were uncertain about the cause of global warming. Among abstracts expressing a position on AGW, 97.1% endorsed the consensus position that humans are causing global warming. In a second phase of this study, we invited authors to rate their own papers. Compared to abstract ratings, a smaller percentage of self-rated papers expressed no position on AGW (35.5%). Among self-rated papers expressing a position on AGW, 97.2% endorsed the consensus. For both abstract ratings and authors' self-ratings, the percentage of endorsements among papers expressing a position on AGW marginally increased over time. Our analysis indicates that the number of papers rejecting the consensus on AGW is a vanishingly small proportion of the published research."

  • The second feature — the Mediterranean Sea — plays a similar role to the continent’s south
  • Mix the geographic features that inhibit unification with the features that facilitate trade and communication and Europe becomes a very rich, very violent place.
  • three places on the Continent where this pattern of fragmentation does not hold
  • The first are the Seine and Loire river valleys
  • The second and third places where the fragmentation pattern does not hold are the Garonne and Rhone river valleys
  • The one thing these three geographic exceptions have in common is that they all have long resided in the political entity known as France.
  • France is nearly always engaged but is only rarely ascendant.
  • Mountain chains, rivers and seas therefore enclose France at all points save for one: the North European Plain.
  • Internally, aside from the Massif Central in the southeast, France is a country of relatively low-lying terrain with occasional hills.
  • The Beauce region is therefore the French core.
  • Paris is also close enough to the Atlantic — connected by the Seine — to benefit from oceanic trade routes but far enough away to be insulated somewhat from a direct naval invasion.
  • In comparison with its continental neighbors, France has almost always been at an economic advantage because of its geography.
  • Phase I: Centralization (843-1453)
  • The Beauce region of France has always been the core of the French state because of its fertile land and strategic location on the North European Plain.
  • Early France faced two problems, both rooted in geography.
  • The first dealt with the plains.
  • The solution to this military reality was feudalism.
  • French, one of the Langue d’oil, did not become the official tongue until the 1500s, and linguistic unification was not completed until the 1800s.
  • England considered continental France their playpen for much of the Middle Ages. In fact, the Norman leaders of England did not distinguish much between their French and English possessions
  • As in the conflict with the Muslims, it was a technological innovation that forced France’s political system to evolve, and this time the shift was toward centralization rather than decentralization.
  • The combination of the political disasters of the feudal period and the success of consolidation in the battles with the English served as the formative period of the French psyche.
  • Phase II: The Hapsburg Challenge and Balance of Power (1506-1700)
  • Europe’s Hapsburg era was a dangerous time for the French.
  • In three major wars — the War of the Spanish Succession (1701-1714), the War of the Austrian Succession (1740-1748) and the Seven Years’ War (1754-1763, against Britain in North America) — France expended great financial resources in efforts to dominate one region or another, only to emerge at each war’s end with little to show for its efforts.
  • Phase III: Nationalism and the Rise of Germany (1789-1945)
  • two equally damning results
  • First, the depleted treasury led to a general breakdown in internal order, contributing to the French Revolution of 1789.
  • Second, Paris’ distraction with England and Spain led it to miss the emergence of Prussia as a serious European power that began to first rival and ultimately superseded Hapsburg Austria for leadership among the cacophony of German kingdoms.
  • One of the many unintended side effects of the French Revolution was the concept of nationalism,
  • From nationalism grew the nation-state, a political entity that harnesses all people sharing a similar ethnicity into a single governing unit.
  • The result was the one near-unipolar moment in European history.
  • Not only was France the only state to have embraced the concept of nationalism, but it also grafted the concept onto an already centralized system, allowing French power to pour forth across Europe and North Africa.
  • From 1803 to 1815, France nearly overwhelmed the rest of Europe before a coalition of nearly every major and minor power on the Continent combined forces to defeat her.
  • The lesson was a simple one, again rooted in geography. Even when France is united and whole, even when she is not under siege, even when her foes are internally distracted and off balance, even when she is led by one of the greatest organizational and military minds in human history, even when she holds the advantage of nationalism — she still lacks the resources and manpower to rule Europe.
  • But most of all the advantage of nationalism spread. Over the next few decades the political innovation of the nation-state spread throughout Europe and in time became a global phenomenon.
  • The culmination of this dichotomy was the events of May-June 1940, when the French military crumbled in less than six weeks. The defeat was by no means solely the result of geopolitical forces, but it sprang from the fundamental imbalance of power between France and a unified Germany.
  • Phase IV: Managing Germany
  • as France is concerned, however, STRATFOR views the entire post-World War II era as a single chapter in French history that has yet to come to a conclusion. In this phase, France is attempting to find a means to live with Germany, a task greatly complicated by recent shifts in the global political geography.
  • And far from being exposed and vulnerable, France found itself facing the most congenial constellation of forces in its history.
  • The stated gains of the EEC/EU have always been economic and political, but the deeper truth is that the European project has always been about French geopolitical fear and ambition.
  • Eventually the Cold War ended, and the Soviet collapse was perceived very differently in France. While most of the free world celebrated, the French fretted.
  • the Soviet collapse led to the reunification of Germany — and that was a top-tier issue.
  • Twenty years on, Germany cannot abandon the European Union without triggering massive internal economic dislocations because of the economic evolutions Maastricht has wrought.
  • that leaves the French with two long-term concerns.
  • First, the cage breaks, Germany goes its own way and attempts to remake Europe to suit its purposes.
  • Second, the cage holds, but it constrains France more than Germany.
  • Geopolitical Imperatives
  • Secure a Larger Hinterland
  • France is the only country on the North European Plain that has an option for expansion into useful territories beyond its core without directly clashing with another major power.
  • Always Look East
  • Being situated at the western end of the North European Plain makes France the only country on the plain that has only one land approach to defend against.
  • Maintain Influence in Regions Beyond Western Europe
  • Unlike the United Kingdom, whose expansion into empire was a natural step in its evolution as a naval power, France’s overseas empire was almost wholly artificial.
  • These colonial assets served one more critical role for Paris: They were disposable.
  • Louisiana was sold for loose change in order to fund the Napoleonic wars, while Algeria was ultimately abandoned — despite being home to some 1 million ethnic French — so that Charles de Gaulle could focus attention on more important matters at home and in the rest of Europe.
  • Be Flexible
  • Geopolitics is not ideological or personal, although few countries have the discipline to understand that.

The Power Law in a Free Society - 0 views

  • If an individual's success in getting their practice adopted more widely increases the probability of getting another practice of theirs widely adopted "by even a fractional amount", this will result in a power law distribution in which a tiny minority of individuals account for the vast majority of the practices that end up gaining wider adoption.

Mass Extinction Easier to Trigger Than Thought - 0 views

  • The cataclysmic extinctions that scoured Earth 200 million years ago might have been easier to trigger than expected, with potentially troubling contemporary implications.
  • Rather than 600,000 years of volcanic activity choking Earth’s atmosphere with carbon dioxide, just a few thousand years apparently sufficed to raise ocean temperatures so potent greenhouse gases trapped in seafloor mud came bubbling up.
  • “It could happen again. It’s only the boundary conditions that we don’t know.”
  • ...5 more annotations...
  • In what scientists call the end-Triassic mass extinction, at least half of all living species simply disappear from the fossil record. The die-off didn’t merely cause ecological disruption. It was so sudden and profound that planetary chemical cycles went haywire for the next several million years.
  • The leading explanation for the extinction invokes extended, climate-altering volcanic activity caused by splitting continental plates, but earlier research by Ruhl suggested a more nuanced and jarring narrative.
  • “A small release of CO2 from volcanoes triggered a small change in the global climate, raising land and ocean temperatures. That led to the release of methane from the seafloor,” said Ruhl.
  • Scientists have raised the possibility that rising global temperatures could release trapped methane into the atmosphere, further raising temperatures and releasing more methane in a feedback loop of warming and planetary disruption. That’s apparently what happened during the end-Triassic extinction.
  • Exactly how much warming would be needed to start the loop anew, and how much methane would flow forth, are open questions. “We could potentially trigger a small increase in ocean temperatures, which triggers methane release,” said Ruhl. “But it’s difficult to quantify how much methane is in the ocean these days. Maybe we have less methane in seafloors now. Maybe we have more.”

    What a lovely headline! Anyway, humans could have an easier time doing stuff that could obliterate us. Viva evolution!

Why Americans Are the Weirdest People in the World - 0 views

  • For instance, the different ways people perceive the Müller-Lyer illusion likely reflects lifetimes spent in different physical environments. American children, for the most part, grow up in box-shaped rooms of varying dimensions. Surrounded by carpentered corners, visual perception adapts to this strange new environment (strange and new in terms of human history, that is) by learning to perceive converging lines in three dimensions.
  • As the three continued their work, they noticed something else that was remarkable: again and again one group of people appeared to be particularly unusual when compared to other populations—with perceptions, behaviors, and motivations that were almost always sliding down one end of the human bell curve.
  • In the end they titled their paper “The Weirdest People in the World?” (pdf) By “weird” they meant both unusual and Western, Educated, Industrialized, Rich, and Democratic. It is not just our Western habits and cultural preferences that are different from the rest of the world, it appears. The very way we think about ourselves and others—and even the way we perceive reality—makes us distinct from other humans on the planet, not to mention from the vast majority of our ancestors. Among Westerners, the data showed that Americans were often the most unusual, leading the researchers to conclude that “American participants are exceptional even within the unusual population of Westerners—outliers among outliers.”

  • The trio of researchers are young—as professors go—good-humored family men. They recalled that they were nervous as the publication time approached. The paper basically suggested that much of what social scientists thought they knew about fundamental aspects of human cognition was likely only true of one small slice of humanity. They were making such a broadside challenge to whole libraries of research that they steeled themselves to the possibility of becoming outcasts in their own fields.
  • “We were scared,” admitted Henrich. “We were warned that a lot of people were going to be upset.” “We were told we were going to get spit on,” interjected Norenzayan. “Yes,” Henrich said. “That we’d go to conferences and no one was going to sit next to us at lunchtime.”
  • Still, I had to wonder whether describing the Western mind, and the American mind in particular, as weird suggested that our cognition is not just different but somehow malformed or twisted. In their paper the trio pointed out cross-cultural studies that suggest that the “weird” Western mind is the most self-aggrandizing and egotistical on the planet: we are more likely to promote ourselves as individuals versus advancing as a group. WEIRD minds are also more analytic, possessing the tendency to telescope in on an object of interest rather than understanding that object in the context of what is around it.
  • The WEIRD mind also appears to be unique in terms of how it comes to understand and interact with the natural world. Studies show that Western urban children grow up so closed off in man-made environments that their brains never form a deep or complex connection to the natural world.
  • Children who grow up constantly interacting with the natural world are much less likely to anthropomorphize other living things into late childhood.
    • anonymous
       
      I did a shit ton of this. I was very internal, didn't have many friends, and came to identify with 'things' as though they were people.
  • Given that people living in WEIRD societies don’t routinely encounter or interact with animals other than humans or pets, it’s not surprising that they end up with a rather cartoonish understanding of the natural world. “Indeed,” the report concluded, “studying the cognitive development of folkbiology in urban children would seem the equivalent of studying ‘normal’ physical growth in malnourished children.”
  • The three insisted that their goal was not to say that one culturally shaped psychology was better or worse than another—only that we’ll never truly understand human behavior and cognition until we expand the sample pool beyond its current small slice of humanity.
  • Despite these assurances, however, I found it hard not to read a message between the lines of their research. When they write, for example, that weird children develop their understanding of the natural world in a “culturally and experientially impoverished environment” and that they are in this way the equivalent of “malnourished children,” it’s difficult to see this as a good thing.
  • THE TURN THAT HENRICH, Heine, and Norenzayan are asking social scientists to make is not an easy one: accounting for the influence of culture on cognition will be a herculean task. Cultures are not monolithic; they can be endlessly parsed. Ethnic backgrounds, religious beliefs, economic status, parenting styles, rural upbringing versus urban or suburban—there are hundreds of cultural differences that individually and in endless combinations influence our conceptions of fairness, how we categorize things, our method of judging and decision making, and our deeply held beliefs about the nature of the self, among other aspects of our psychological makeup.

      This is another place where my love of long-term thinking rears its head. So modern as we imagine ourselves, with all our fancy machines, we are still bareinfants when it comes to reckoning about ourselves.
  • Recent research has shown that people in “tight” cultures, those with strong norms and low tolerance for deviant behavior (think India, Malaysia, and Pakistan), develop higher impulse control and more self-monitoring abilities than those from other places.
  • Men raised in the honor culture of the American South have been shown to experience much larger surges of testosterone after insults than do Northerners.
  • As Norenzayan sees it, the last few generations of psychologists have suffered from “physics envy,” and they need to get over it.
  • The job, experimental psychologists often assumed, was to push past the content of people’s thoughts and see the underlying universal hardware at work. “This is a deeply flawed way of studying human nature,” Norenzayan told me, “because the content of our thoughts and their process are intertwined.” In other words, if human cognition is shaped by cultural ideas and behavior, it can’t be studied without taking into account what those ideas and behaviors are and how they are different from place to place.
  • This new approach suggests the possibility of reverse-engineering psychological research: look at cultural content first; cognition and behavior second. Norenzayan’s recent work on religious belief is perhaps the best example of the intellectual landscape that is now open for study.
  • “I remember opening textbook after textbook and turning to the index and looking for the word ‘religion,’ ” he told me, “Again and again the very word wouldn’t be listed. This was shocking. How could psychology be the science of human behavior and have nothing to say about religion? Where I grew up you’d have to be in a coma not to notice the importance of religion on how people perceive themselves and the world around them.”
  • He has suggested that there may be a connection between the growth of religions that believe in “morally concerned deities”—that is, a god or gods who care if people are good or bad—and the evolution of large cities and nations.
  • If religion was necessary in the development of large-scale societies, can large-scale societies survive without religion? Norenzayan points to parts of Scandinavia with atheist majorities that seem to be doing just fine. They may have climbed the ladder of religion and effectively kicked it away. Or perhaps, after a thousand years of religious belief, the idea of an unseen entity always watching your behavior remains in our culturally shaped thinking even after the belief in God dissipates or disappears.
  • almost every major theorist on human behavior in the last 100 years predicted that it was just a matter of time before religion was a vestige of the past. But the world persists in being a very religious place.
  • HENRICH, HEINE, AND NORENZAYAN’S FEAR of being ostracized after the publication of the WEIRD paper turned out to be misplaced. Response to the paper, both published and otherwise, has been nearly universally positive, with more than a few of their colleagues suggesting that the work will spark fundamental changes. “I have no doubt that this paper is going to change the social sciences,” said Richard Nisbett, an eminent psychologist at the University of Michigan. “It just puts it all in one place and makes such a bold statement.”
  • At its heart, the challenge of the WEIRD paper is not simply to the field of experimental human research (do more cross-cultural studies!); it is a challenge to our Western conception of human nature. For some time now, the most widely accepted answer to the question of why humans, among all animals, have so successfully adapted to environments across the globe is that we have big brains with the ability to learn, improvise, and problem-solve.
  • Henrich has challenged this “cognitive niche” hypothesis with the “cultural niche” hypothesis. He notes that the amount of knowledge in any culture is far greater than the capacity of individuals to learn or figure it all out on their own.
  • He suggests that individuals tap that cultural storehouse of knowledge simply by mimicking (often unconsciously) the behavior and ways of thinking of those around them. We shape a tool in a certain manner, adhere to a food taboo, or think about fairness in a particular way, not because we individually have figured out that behavior’s adaptive value, but because we instinctively trust our culture to show us the way.

      Goodness, though! I'm in TOTAL control of everything! :P
  • The unique trick of human psychology, these researchers suggest, might be this: our big brains are evolved to let local culture lead us in life’s dance.
  • People are not “plug and play,” as he puts it, and you cannot expect to drop a Western court system or form of government into another culture and expect it to work as it does back home.
  • Because of our peculiarly Western way of thinking of ourselves as independent of others, this idea of the culturally shaped mind doesn’t go down very easily.
  • That we in the West develop brains that are wired to see ourselves as separate from others may also be connected to differences in how we reason, Heine argues. Unlike the vast majority of the world, Westerners (and Americans in particular) tend to reason analytically as opposed to holistically.
  • That is, the American mind strives to figure out the world by taking it apart and examining its pieces.
  • Shown another way, in a different test analytic Americans will do better on something called the “rod and frame” task, where one has to judge whether a line is vertical even though the frame around it is skewed. Americans see the line as apart from the frame, just as they see themselves as apart from the group.
  • Heine and others suggest that such differences may be the echoes of cultural activities and trends going back thousands of years. Whether you think of yourself as interdependent or independent may depend on whether your distant ancestors farmed rice (which required a great deal of shared labor and group cooperation) or herded animals (which rewarded individualism and aggression).
  • These psychological trends and tendencies may echo down generations, hundreds of years after the activity or situation that brought them into existence has disappeared or fundamentally changed.
  • And here is the rub: the culturally shaped analytic/individualistic mind-sets may partly explain why Western researchers have so dramatically failed to take into account the interplay between culture and cognition. In the end, the goal of boiling down human psychology to hardwiring is not surprising given the type of mind that has been designing the studies. Taking an object (in this case the human mind) out of its context is, after all, what distinguishes the analytic reasoning style prevalent in the West. Similarly, we may have underestimated the impact of culture because the very ideas of being subject to the will of larger historical currents and of unconsciously mimicking the cognition of those around us challenges our Western conception of the self as independent and self-determined. The historical missteps of Western researchers, in other words, have been the predictable consequences of the WEIRD mind doing the thinking.
  •  
    "The growing body of cross-cultural research that the three researchers were compiling suggested that the mind's capacity to mold itself to cultural and environmental settings was far greater than had been assumed. The most interesting thing about cultures may not be in the observable things they do-the rituals, eating preferences, codes of behavior, and the like-but in the way they mold our most fundamental conscious and unconscious thinking and perception."

A New Reality in U.S.-Israeli Relations - 0 views

  • In the United States, the political crisis over the federal budget and the struggle to grow the economy and reduce unemployment has dominated the president's and the country's attention.
  • The Israeli elections turned on domestic issues, ranging from whether the ultra-Orthodox would be required to serve in Israel Defense Forces, as other citizens are, to a growing controversy over economic inequality in Israel. 
  • What is interesting is at this point, while Israelis continue to express concern about foreign policy, they are most passionate on divisive internal social issues. Similarly, although there continues to be a war in Afghanistan, the American public is heavily focused on economic issues. Under these circumstances the interesting question is not what Obama and Netanyahu will talk about but whether what they discuss will matter much.

  • After more than a decade of being focused on the Islamic world and moving aggressively to try to control threats in the region militarily, the United States is moving toward a different stance. The bar for military intervention has been raised.
  • Therefore, the United States has, in spite of recent statements, not militarily committed itself to the Syrian crisis, and when the French intervened in Mali the United States played a supporting role. The intervention in Libya, where France and the United Kingdom drew the United States into the action, was the first manifestation of Washington's strategic re-evaluation.
  • That desire was there from the U.S. experience in Iraq and was the realization that the disposal of an unsavory regime does not necessarily -- or even very often -- result in a better regime.
  • The United States' new stance ought to frighten the Israelis. In Israel's grand strategy, the United States is the ultimate guarantor of its national security and underwrites a portion of its national defense. If the United States becomes less inclined to involve itself in regional adventures, the question is whether the guarantees implicit in the relationship still stand.
  • The issue is not whether the United States would intervene to protect Israel's existence; save from a nuclear-armed Iran, there is no existential threat to Israel's national interest. Rather, the question is whether the United States is prepared to continue shaping the dynamics of the region in areas where Israel lacks political influence and is not able to exert military control.
  • To put it differently, the Israelis' understanding of the American role is to control events that endanger Israel and American interests under the assumption that Israeli and American interests are identical. The idea that they are always identical has never been as true as politicians on both sides have claimed, but more important, the difficulties of controlling the environment have increased dramatically for both sides.
  • The problem for Israel at this point is that it is not able to do very much in the area that is its responsibility.
  • But the most shocking thing to Israel was how little control it actually had over events in Egypt and the future of its ties to Egypt.
  • But the power of the military will not be the sole factor in the long-term sustainability of the treaty. Whether it survives or not ultimately is not a matter that Israel has much control over.
  • The Israelis have always assumed that the United States can control areas where they lack control. And some Israelis have condemned the United States for not doing more to manage events in Egypt. But the fact is that the United States also has few tools to control the evolution of Egypt, apart from some aid to Egypt and its own relationship with the Egyptian military.
  • It may or may not be in the American interest to do something in any particular case, but the problem in this case is that although a hostile Egypt is not in the Americans' interest, there is actually little the United States can do to control events in Egypt.
  • Syrian President Bashar al Assad is a known quantity to Israel. He is by no means a friend, but his actions and his father's have always been in the pursuit of their own interest and therefore have been predictable. The opposition is an amorphous entity whose ability to govern is questionable and that is shot through with Islamists who are at least organized and know what they want.
  • Indeed, the hints of American weapons shipments to the rebels at some point concern Israel as much as no weapons shipments.
  • The Iranian situation is equally complex. It is clear that the Israelis, despite rhetoric to the contrary, will not act unilaterally against Iran's nuclear weapons. The risks of failure are too high, and the consequences of Iranian retaliation against fundamental American interests, such as the flow of oil through the Strait of Hormuz, are too substantial.
  • The American view is that an Iranian nuclear weapon is not imminent and Iran's ultimate ability to build a deliverable weapon is questionable. Therefore, regardless of what Israel wants, and given the American doctrine of military involvement as a last resort when it significantly affects U.S. interests, the Israelis will not be able to move the United States to play its traditional role of assuming military burdens to shape the region.
  • There has therefore been a very real if somewhat subtle shift in the U.S.-Israeli relationship. Israel has lost the ability, if it ever had it, to shape the behavior of countries on its frontier. Egypt and Syria will do what they will do. At the same time, the United States has lost the inclination to intervene militarily in the broader regional conflict and has limited political tools. Countries like Saudi Arabia, which might be inclined to align with U.S. strategy, find themselves in a position of creating their own strategy and assuming the risks. 
  • For the United States, there are now more important issues than the Middle East, such as the domestic economy.
  • It will continue to get aid that it no longer needs and will continue to have military relations with the United States, particularly in developing military technology. But for reasons having little to do with Israel, Washington's attention is not focused on the region or at least not as obsessively as it had been since 2001. 
  • Like Israel, the United States has realized the limits and costs of such a strategy, and Israel will not talk the United States out of it, as the case of Iran shows. In addition, there is no immediate threat to Israel that it must respond to. It is, by default, in a position of watching and waiting without being clear as to what it wants to see. Therefore it should be no surprise that Israel, like the United States, is focused on domestic affairs.
  • It also puts Israel in a reactive position. The question of the Palestinians is always there. Israel's policy, like most of its strategic policy, is to watch and wait. It has no inclination to find a political solution because it cannot predict what the consequences of either a solution or an attempt to find one would be.
  •  Israel has lost the initiative and, more important, it now knows it has lost the initiative. It has looked to the United States to take the initiative, but on a much broader scale Washington faces the same reality as Israel with less at stake and therefore less urgency.
  • This is not a strain in the U.S.-Israeli relationship in the sense of anger and resentment, although those exist on both sides. Rather it is like a marriage that continues out of habit but whose foundation has withered.
  • In private I expect a sullen courtesy and in public an enthusiastic friendship, much as an old, bored married couple, not near a divorce, but far from where they were when they were young. Neither party is what it once was; each suspects that it is the other's fault. In the end, each has its own fate, linked by history to each other but no longer united.
    • anonymous
       
      What a hell of a closer.
  •  
    "Normally, summits between Israel and the United States are filled with foreign policy issues on both sides, and there will be many discussed at this meeting, including Iran, Syria and Egypt. But this summit takes place in an interesting climate, because both the Americans and Israelis are less interested in foreign and security matters than they are in their respective domestic issues."
