If Evolution Has Implications for Religion, Can We Justify Teaching It in Public School... - 0 views

  • Evolutionary biology is a science, so it can be legally taught in public schools when it's treated as a science and isn't promoted as a support for atheism or materialism.
  • few would deny that Darwinian evolution has larger implications that aren't friendly to theism
  • the conversation focuses strictly on the science, the implications are still there.

  • Do the larger religious (or anti-religious) implications of a scientific theory make it inadmissible for instruction in public schools? They shouldn't.
  • just because we're declaring the teaching of evolution to be constitutional doesn't mean we that it has no connections to religion
  • while it may sound odd to hear that we can (sometimes) declare something constitutional to teach in public schools even though it touches upon religion, there's good legal precedent for such a finding.
  • a government policy establishes religion if its "principal or primary effect" is one that "advances or inhibits" religion.
  • the statute must have a secular legislative purpose; second, its principal or primary effect must be one that neither advances nor inhibits religion; finally, the statute must not foster an excessive government entanglement with religion
  • a government policy is unconstitutional if it has a "primary" or "principal" effect that advances (or inhibits) religion. However, in light of this second part, the Supreme Court has also developed a legal doctrine called the "incidental effects" or "secondary effects" doctrine which says that government law or policy may have "secondary" or "incidental" effects that touch upon religion and not violate the Establishment Clause.
  • Secondary effects that touch upon religion are not constitutionally fatal.
  • the Court held in Lynch v. Donnelly that "not every law that confers an indirect, remote, or incidental benefit upon [religion] is, for that reason alone, constitutionally invalid"
  • if government aid "is allocated on the basis of neutral, secular criteria that neither favor nor disfavor religion, and is made available to both religious and secular beneficiaries on a nondiscriminatory basis," then any effects upon religion are merely incidental.
  • evolutionary biology is based upon science, when we teach it as a science, the primary effect is to advance scientific knowledge.
  • a scientific theory like evolution does speak to ultimate questions about origins, which are also addressed by religion
  • it certainly touches upon religious questions. But when we discuss Darwinian evolution strictly on a scientific level, any effects upon religion are "secondary" or "incidental" compared to their primary effect of advancing scientific knowledge.
  • if creation science were a scientific theory, it could have been taught because any its touching upon religion would have been a secondary effect
  • approach was also followed in Crowley v. Smithsonian Institution, where a federal judge rejected arguments that Smithsonian exhibits on evolution established "secular humanism" because the "impact [on religion] is at most incidental to the primary effect of presenting a body of scientific knowledge"
  • Because evolution is based upon science, any effects upon religion would not bar its teaching.
  • [I]f a theory has scientific value and evidence to support it, its primary effect would be to advance knowledge of the natural world, not to advance religion
  • ultimate goal of schools is to educate students. Where a theory has scientific value and supporting evidence, it provides a basis for knowledge. Whether it coincidentally advances religion should not matter.
  • one can legally justify teaching evolution while being sensitive to the fact that it has larger implications that touch upon the religious beliefs of many Americans.
  • best of both worlds. It allows science to be taught in the science classroom while respecting the beliefs of people who have religious objections to evolution.

Bacteria Have a Social Contract, and Unnamed Natural Laws | Big Think - 1 views

  • the evolutionary logic of relationships beyond rivalry
  • ~98% of bacterial species don’t thrive outside mixed-species colonies.

  • You’re in a collective extended “survival vehicle” relationship.
  • In a kind of no-brainer biochemical “social contract,” bacterial colonies, like human communities, have to handle the “common good” (suppressing cheating, free-riding, the “tragedy of the commons,” etc).
  • We dominate because we’re the best cooperators (Yuval Harari).
  • Evolution is itself a free-floating logic pattern (for discovering other, ever more effective logic patterns, and enacting “competence without comprehension").
  • Evolution’s logic is like geometry’s: in both relevant patterns and results arise from the intrinsic logic of the elements involved. In geometry, it’s lines, planes, etc. In evolution it’s kinetic functions like survival, varying replication, and adaptation.
  •  
    I found this article very interesting. Evolution does not happen physically. There is also evolution in the social behavior and relationship in a specie. Even simple organisms like single-celled bacteria have certain behaviors that suggest evolution in "social behavior" even though they don't have brain or intelligence. I feel like it is just like the hydrogen bonds in chemistry that it forms naturally without a doubt. Common good is the ultimate goal of the nature. I think the logic is evolution is very amazing as all the results are because of mindless discovery. --Sissi (3/30/2017)

How Did Consciousness Evolve? - The Atlantic - 0 views

  • Theories of consciousness come from religion, from philosophy, from cognitive science, but not so much from evolutionary biology. Maybe that’s why so few theories have been able to tackle basic questions such as: What is the adaptive value of consciousness? When did it evolve and what animals have it?
  • The Attention Schema Theory (AST), developed over the past five years, may be able to answer those questions.
  • The theory suggests that consciousness arises as a solution to one of the most fundamental problems facing any nervous system: Too much information constantly flows in to be fully processed. The brain evolved increasingly sophisticated mechanisms for deeply processing a few select signals at the expense of others, and in the AST, consciousness is the ultimate result of that evolutionary sequence
  • ...23 more annotations...
  • Even before the evolution of a central brain, nervous systems took advantage of a simple computing trick: competition.
  • It coordinates something called overt attention – aiming the satellite dishes of the eyes, ears, and nose toward anything important.
  • Selective enhancement therefore probably evolved sometime between hydras and arthropods—between about 700 and 600 million years ago, close to the beginning of complex, multicellular life
  • The next evolutionary advance was a centralized controller for attention that could coordinate among all senses. In many animals, that central controller is a brain area called the tectum
  • At any moment only a few neurons win that intense competition, their signals rising up above the noise and impacting the animal’s behavior. This process is called selective signal enhancement, and without it, a nervous system can do almost nothing.
  • With the evolution of reptiles around 350 to 300 million years ago, a new brain structure began to emerge – the wulst. Birds inherited a wulst from their reptile ancestors. Mammals did too, but our version is usually called the cerebral cortex and has expanded enormously
  • According to fossil and genetic evidence, vertebrates evolved around 520 million years ago. The tectum and the central control of attention probably evolved around then, during the so-called Cambrian Explosion when vertebrates were tiny wriggling creatures competing with a vast range of invertebrates in the sea.
  • The tectum is a beautiful piece of engineering. To control the head and the eyes efficiently, it constructs something called an internal model, a feature well known to engineers. An internal model is a simulation that keeps track of whatever is being controlled and allows for predictions and planning.
  • The tectum’s internal model is a set of information encoded in the complex pattern of activity of the neurons. That information simulates the current state of the eyes, head, and other major body parts, making predictions about how these body parts will move next and about the consequences of their movement
  • In fish and amphibians, the tectum is the pinnacle of sophistication and the largest part of the brain. A frog has a pretty good simulation of itself.
  • All vertebrates—fish, reptiles, birds, and mammals—have a tectum. Even lampreys have one, and they appeared so early in evolution that they don’t even have a lower jaw. But as far as anyone knows, the tectum is absent from all invertebrates
  • The cortex also takes in sensory signals and coordinates movement, but it has a more flexible repertoire. Depending on context, you might look toward, look away, make a sound, do a dance, or simply store the sensory event in memory in case the information is useful for the future.
  • The most important difference between the cortex and the tectum may be the kind of attention they control. The tectum is the master of overt attention—pointing the sensory apparatus toward anything important. The cortex ups the ante with something called covert attention. You don’t need to look directly at something to covertly attend to it. Even if you’ve turned your back on an object, your cortex can still focus its processing resources on it
  • The cortex needs to control that virtual movement, and therefore like any efficient controller it needs an internal model. Unlike the tectum, which models concrete objects like the eyes and the head, the cortex must model something much more abstract. According to the AST, it does so by constructing an attention schema—a constantly updated set of information that describes what covert attention is doing moment-by-moment and what its consequences are
  • Covert attention isn’t intangible. It has a physical basis, but that physical basis lies in the microscopic details of neurons, synapses, and signals. The brain has no need to know those details. The attention schema is therefore strategically vague. It depicts covert attention in a physically incoherent way, as a non-physical essence
  • this, according to the theory, is the origin of consciousness. We say we have consciousness because deep in the brain, something quite primitive is computing that semi-magical self-description.
  • I’m reminded of Teddy Roosevelt’s famous quote, “Do what you can with what you have where you are.” Evolution is the master of that kind of opportunism. Fins become feet. Gill arches become jaws. And self-models become models of others. In the AST, the attention schema first evolved as a model of one’s own covert attention. But once the basic mechanism was in place, according to the theory, it was further adapted to model the attentional states of others, to allow for social prediction. Not only could the brain attribute consciousness to itself, it began to attribute consciousness to others.
  • In the AST’s evolutionary story, social cognition begins to ramp up shortly after the reptilian wulst evolved. Crocodiles may not be the most socially complex creatures on earth, but they live in large communities, care for their young, and can make loyal if somewhat dangerous pets.
  • If AST is correct, 300 million years of reptilian, avian, and mammalian evolution have allowed the self-model and the social model to evolve in tandem, each influencing the other. We understand other people by projecting ourselves onto them. But we also understand ourselves by considering the way other people might see us.
  • t the cortical networks in the human brain that allow us to attribute consciousness to others overlap extensively with the networks that construct our own sense of consciousness.
  • Language is perhaps the most recent big leap in the evolution of consciousness. Nobody knows when human language first evolved. Certainly we had it by 70 thousand years ago when people began to disperse around the world, since all dispersed groups have a sophisticated language. The relationship between language and consciousness is often debated, but we can be sure of at least this much: once we developed language, we could talk about consciousness and compare notes
  • Maybe partly because of language and culture, humans have a hair-trigger tendency to attribute consciousness to everything around us. We attribute consciousness to characters in a story, puppets and dolls, storms, rivers, empty spaces, ghosts and gods. Justin Barrett called it the Hyperactive Agency Detection Device, or HADD
  • the HADD goes way beyond detecting predators. It’s a consequence of our hyper-social nature. Evolution turned up the amplitude on our tendency to model others and now we’re supremely attuned to each other’s mind states. It gives us our adaptive edge. The inevitable side effect is the detection of false positives, or ghosts.

National - Robert Wright - Creationists vs. Evolutionists: An American Story - The Atla... - 0 views

  • About half of Americans--46 percent, in the latest Gallup Poll--believe human beings weren't created by evolution. Over at the Daily Dish, Andrew Sullivan says this is a grave problem. "I simply do not know how you construct a civil discourse indispensable to a functioning democracy with this vast a gulf between citizens in their basic understanding of the world." Over at Mother Jones, Kevin Drum says Andrew should calm down. "This 46% number has barely budged over the past three decades

  • Over the past two years, the portion of respondents who don't believe in evolution has grown by six percentage points. Where did those people come from? The graph suggests they're people who had previously believed in an evolution guided by God--a group whose size dropped by a corresponding six percentage points. It's as if people who had previously seen evolution and religion as compatible were told by the new militant Darwinians, "No, you must choose: Which is it, evolution or religion?"--and pretty much all of them chose religion.

Book Review: 'A New History of Life' by Peter Ward and Joe Kirschvink - WSJ - 0 views

  • I imagine that physicists are similarly deluged with revelations about how to build a perpetual-motion machine or about the hitherto secret truth behind relativity. And so I didn’t view the arrival of “A New History of Life” with great enthusiasm.
  • subtitle breathlessly promises “radical new discoveries about the origins and evolution of life on earth,” while the jacket copy avers that “our current paradigm for understanding the history of life on Earth dates back to Charles Darwin’s time, yet scientific advances of the last few decades have radically reshaped that aging picture.”
  • authors Peter Ward and Joe Kirschvink are genuine scientists—paleontologists, to be exact. And they can write.
  • ...16 more annotations...
  • even genuine scientists are human and as such susceptible to the allure of offering up new paradigms (as the historian of science Thomas Kuhn put it)
  • paleontologist Stephen Jay Gould insisted that his conception of “punctuated equilibria” (a kind of Marxist biology that blurred the lines between evolution and revolution), which he developed along with fellow paleontologist Niles Eldredge, upended the traditional Darwinian understanding of how natural selection works.
  • This notion doesn’t constitute a fundamental departure from plain old evolution by natural selection; it simply italicizes that sometimes the process is comparatively rapid, other times slower.
  • In addition, they have long had a peculiar perspective on evolution, because of the limitations of the fossil record
  • Darwin was a pioneering geologist as well as the greatest of all biologists, and his insights were backgrounded by the key concept of uniformitarianism, as advocated by Charles Lyell, his friend and mentor
  • previously regnant paradigm among geologists had been “catastrophism
  • fossil record was therefore seen as reflecting the creation and extinction of new species by an array of dramatic and “unnatural” dei ex machina.
  • Of late, however, uniformitarianism has been on a losing streak. Catastrophism is back, with a bang . . . or a flood, or a burst of extraterrestrial radiation, or an onslaught of unpleasant, previously submerged chemicals
  • This emphasis on catastrophes is the first of a triad of novelties on which “A New History of Life” is based. The second involves an enhanced role for some common but insufficiently appreciated inorganic molecules, notably carbon dioxide, oxygen and hydrogen sulfide.
  • Life didn’t so much unfold smoothly over hundreds of millions of years as lurch chaotically in response to diverse crises and opportunities: too much oxygen, too little carbon dioxide, too little oxygen, too much carbon dioxide, too hot, too cold
  • So far, so good, except that in their eagerness to emphasize what is new and different, the authors teeter on the verge of the same trap as Gould: exaggerating the novelty of their own ideas.
  • Things begin to unravel when it comes to the third leg of Messrs. Ward and Kirschvink’s purported paradigmatic novelty: a supposed role for ecosystems—rain forests, deserts, rivers, coral reefs, deep-sea vents—as units of evolutionary change
  • “While the history of life may be populated by species,” they write, “it has been the evolution of ecosystems that has been the most influential factor in arriving at the modern-day assemblage of life. . . . [W]e know that on occasion in the deep past entirely new ecosystems appear, populated by new kinds of life.” True enough, but it is those “new kinds of life,” not whole ecosystems, upon which natural selection acts.
  • One of the most common popular misconceptions about evolution is that it proceeds “for the good of the species.”
  • The problem is that smaller, nimbler units are far more likely to reproduce differentially than are larger, clumsier, more heterogeneous ones. Insofar as ecosystems are consequential for evolution—and doubtless they are—it is because, like occasional catastrophes, they provide the immediate environment within which something not-so-new is acted out.
  • This is natural selection doing its same-old, same-old thing: acting by a statistically potent process of variation combined with selective retention and differential reproduction, a process that necessarily operates within the particular ecosystem that a given lineage occupies.

Adam Kirsch: Art Over Biology | The New Republic - 1 views

  • Nietzsche, who wrote in Human, All Too Human, under the rubric “Art dangerous for the artist,” about the particular ill-suitedness of the artist to flourishing in a modern scientific age: When art seizes an individual powerfully, it draws him back to the views of those times when art flowered most vigorously.... The artist comes more and more to revere sudden excitements, believes in gods and demons, imbues nature with a soul, hates science, becomes unchangeable in his moods like the men of antiquity, and desires the overthrow of all conditions that are not favorable to art.... Thus between him and the other men of his period who are the same age a vehement antagonism is finally generated, and a sad end
  • What is modern is the sense of the superiority of the artist’s inferiority, which is only possible when the artist and the intellectual come to see the values of ordinary life—prosperity, family, worldly success, and happiness—as inherently contemptible.
  • Art, according to a modern understanding that has not wholly vanished today, is meant to be a criticism of life, especially of life in a materialist, positivist civilization such as our own. If this means the artist does not share in civilization’s boons, then his suffering will be a badge of honor.
  • ...18 more annotations...
  • The iron law of Darwinian evolution is that everything that exists strives with all its power to reproduce, to extend life into the future, and that every feature of every creature can be explained as an adaptation toward this end. For the artist to deny any connection with the enterprise of life, then, is to assert his freedom from this universal imperative; to reclaim negatively the autonomy that evolution seems to deny to human beings. It is only because we can freely choose our own ends that we can decide not to live for life, but for some other value that we posit. The artist’s decision to produce spiritual offspring rather than physical ones is thus allied to the monk’s celibacy and the warrior’s death for his country, as gestures that deny the empire of mere life.
  • Animals produce beauty on their bodies; humans can also produce it in their artifacts. The natural inference, then, would be that art is a human form of sexual display, a way for males to impress females with spectacularly redundant creations.
  • For Darwin, the human sense of beauty was not different in kind from the bird’s.
  • Still, Darwin recognized that the human sense of beauty was mediated by “complex ideas and trains of thought,” which make it impossible to explain in terms as straightforward as a bird’s:
  • with the rise of evolutionary psychology, it was only a matter of time before the attempt was made to explain art in Darwinian terms. After all, if ethics and politics can be explained by game theory and reciprocal altruism, there is no reason why aesthetics should be different: in each case, what appears to be a realm of human autonomy can be reduced to the covert expression of biological imperatives
  • Put more positively, one might say that any given work of art can be discussed critically and historically, but not deduced from the laws of evolution.
  • Still, there is an unmistakable sense in discussions of Darwinian aesthetics that by linking art to fitness, we can secure it against charges of irrelevance or frivolousness—that mattering to reproduction is what makes art, or anything, really matter.
  • In particular, Darwin suggests that it is impossible to explain the history or the conventions of any art by the general imperatives of evolution
  • Dutton’s Darwinism was aesthetically conservative: “Darwinian aesthetics,” he wrote, “can restore the vital place of beauty, skill, and pleasure as high artistic values.” Dutton’s argument has recently been reiterated and refined by a number of new books,
  • “The universality of art and artistic behaviors, their spontaneous appearance everywhere across the globe ... and the fact that in most cases they can be easily recognized as artistic across cultures suggest that they derive from a natural, innate source: a universal human psychology.”
  • Again like language, art is universal in the sense that any local expression of it can be “learned” by anyone.
  • Yet earlier theorists of evolution were reluctant to say that art was an evolutionary adaptation like language, for the simple reason that it does not appear to be evolutionarily adaptive.
  • Stephen Jay Gould suggested that art was not an evolutionary adaptation but what he called a “spandrel”—that is, a showy but accidental by-product of other adaptations that were truly functiona
  • the very words “success” and “failure,” despite themselves, bring an emotive and ethical dimension into the discussion, so impossible is it for human beings to inhabit a valueless world. In the nineteenth century, the idea that fitness for survival was a positive good motivated social Darwinism and eugenics. Proponents of these ideas thought that in some way they were serving progress by promoting the flourishing of the human race, when the basic premise of Darwinism is that there is no such thing as progress or regress, only differential rates of reproduction
  • The first popular effort in this direction was the late Denis Dutton’s much-discussed book The Art Instinct, which appeared in 2009.
  • Boyd begins with the premise that human beings are pattern-seeking animals: both our physical perceptions and our social interactions are determined by our brain’s innate need to find and to
  • Art, then, can be defined as the calisthenics of pattern-finding. “Just as animal physical play refines performance, flexibility, and efficiency in key behaviors,” Boyd writes, “so human art refines our performance in our key perceptual and cognitive modes, in sight (the visual arts), sound (music), and social cognition (story). These three modes of art, I propose, are adaptations ... they show evidence of special design in humans, design that offers survival and especially reproductive advantages.”

Creationists on Texas Panel for Biology Textbooks - NYTimes.com - 0 views

  • As Texas gears up to select biology textbooks for use by high school students over the next decade, the panel responsible for reviewing submissions from publishers has stirred controversy because a number of its members do not accept evolution and climate change as scientific truth.
  • Some Texans worry that ideologically driven review panel members and state school board members are slowly eroding science education in the state.

  • ...6 more annotations...
  • By questioning the science — often getting down to very technical details — the evolution challengers in Texas are following a strategy increasingly deployed by others around the country. There is little open talk of creationism. Instead they borrow buzzwords common in education, “critical thinking,” saying there is simply not enough evidence to prove evolution.
  • If textbooks do not present alternative viewpoints or explain what they describe as “the controversy,” they say students will be deprived of a core concept of education — learning how to make up their own minds.
  • Historically, given the state’s size, Texas’ textbook selections have had an outsize impact on what ended up in classrooms throughout the country. That influence is waning somewhat because publishers can customize digital editions and many states are moving to adopt new science standards with evolution firmly at their center.
  • Jessica Womack, who traveled from near Houston this month to participate in a rally before a public hearing on the books, recounted how her daughter, now 14, had been shamed by a third-grade teacher for raising her hand when the class was asked who believed in evolution.
  • educators note that standards and textbooks can be overridden by teachers who themselves question evolution.
  • In a survey of more than 900 high school biology teachers conducted by Michael Berkman and Eric Plutzer, political scientists at Penn State University, one in eight said they taught creationism or its cousin, intelligent design, as valid scientific alternatives to Darwinian evolutionary theory.

Evolution and the American Myth of the Individual - NYTimes.com - 0 views

  • the country’s two main political parties have “fundamental philosophical differences.” But what exactly does that mean?
  • In a broad sense, Democrats, particularly the more liberal among them, are more likely to embrace the communal nature of individual lives and to strive for policies that emphasize that understanding.
  • Republicans, especially libertarians and Tea Party members on the ideological fringe, however, often trace their ideas about freedom and liberty back to Enlightenment thinkers of the 17th and 18th centuries, who argued that the individual is the true measure of human value, and each of us is naturally entitled to act in our own best interests free of interference by others. Self-described libertarians generally also pride themselves on their high valuation of logic and reasoning over emotion.
  • ...13 more annotations...
  • Philosophers from Aristotle to Hegel have emphasized that human beings are essentially social creatures, that the idea of an isolated individual is a misleading abstraction. So it is not just ironic but instructive that modern evolutionary research, anthropology, cognitive psychology and neuroscience have come down on the side of the philosophers who have argued that the basic unit of human social life is not and never has been the selfish, self-serving individual.
  • Contrary to libertarian and Tea Party rhetoric, evolution has made us a powerfully social species, so much so that the essential precondition of human survival is and always has been the individual plus his or her relationships with others.
  • in the eyes of many conservative Americans today, religion and evolution do not mix. You either accept what the Bible tells us or what Charles Darwin wrote, but not both
  • The irony here is that when it comes to our responsibilities to one another as human beings, religion and evolution nowadays are not necessarily on opposite sides of the fence.
  • as Matthew D. Lieberman, a social neuroscience researcher at the University of California, Los Angeles, has written: “we think people are built to maximize their own pleasure and minimize their own pain. In reality, we are actually built to overcome our own pleasure and increase our own pain in the service of following society’s norms.”
  • Jean-Jacques Rousseau famously declared in “The Social Contract” (1762) that each of us is born free and yet everywhere we are in chains. He did not mean physical chains. He meant social ones. We now know he was dead wrong. Human evolution has made us obligate social creatures. Even if some of us may choose sooner or later to disappear into the woods or sit on a mountaintop in deep meditation, we humans are able to do so only if before such individualistic anti-social resolve we have first been socially nurtured and socially taught survival arts by others. The distinction Rousseau and others tried to draw between “natural liberty, which is bounded only by the strength of the individual” and “civil liberty, which is limited by the general will” is fanciful, not factual.
  • Why then did Rousseau and others make up stories about human history if they didn’t really believe them? The simple answer, at least during the Enlightenment, was that they wanted people to accept their claim that civilized life is based on social conventions, or contracts, drawn up at least figuratively speaking by free, sane and equal human beings — contracts that could and should be extended to cover the moral and working relationships that ought to pertain between rulers and the ruled.
  • In short, their aims were political, not historical, scientific or religious.
  • what Rousseau and others crafted as arguments in favor of their ideas all had the earmarks of primitive mythology
  • Bronislaw Malinowski argued almost a century ago: “Myth fulfills in primitive culture an indispensable function: it expresses, enhances, and codifies belief, it safeguards and enforces morality, it vouches for the efficiency of ritual and contains practical rules for the guidance of man.”
  • Myths achieve this social function, he observed, by serving as guides, or charters, for moral values, social order and magical belief.
  • not all myths make good charters for faith and wisdom. The sanctification of the rights of individuals and their liberties today by libertarians and Tea Party conservatives is contrary to our evolved human nature as social animals. There was never a time in history before civil society when we were each totally free to do whatever we elected to do. We have always been social and caring creatures. The thought that it is both rational and natural for each of us to care only for ourselves, our own preservation, and our own achievements is a treacherous fabrication. This is not how we got to be the kind of species we are today.
  • Nor is this what the world’s religions would ask us to believe.

The Selfish Gene turns 40 | Science | The Guardian - 0 views

  • The idea was this: genes strive for immortality, and individuals, families, and species are merely vehicles in that quest. The behaviour of all living things is in service of their genes hence, metaphorically, they are selfish.
  • Before this, it had been proposed that natural selection was honing the behaviour of living things to promote the continuance through time of the individual creature, or family, or group or species. But in fact, Dawkins said, it was the gene itself that was trying to survive, and it just so happened that the best way for it to survive was in concert with other genes in the impermanent husk of an individual
  • This gene-centric view of evolution also began to explain one of the oddities of life on Earth – the behaviour of social insects. What is the point of a drone bee, doomed to remain childless and in the service of a totalitarian queen? Suddenly it made sense that, with the gene itself steering evolution, the fact that the drone shared its DNA with the queen meant that its servitude guarantees not the individual’s survival, but the endurance of the genes they shar

  • his true legacy is The Selfish Gene and its profound effect on multiple generations of scientists and lay readers. In a sense, The Selfish Gene and Dawkins himself are bridges, both intellectually and chronologically, between the titans of mid-century biology – Ronald Fisher, Trivers, Hamilton, Maynard Smith and Williams – and our era of the genome, in which the interrogation of DNA dominates the study of evolution.
  • Since 1976, our understanding of why life is the way it is has blossomed and changed. Once the gene became the dominant idea in biology in the 1990s there followed a technological goldrush – the Human Genome Project – to find them all.
  • Genes aren’t what they used to be either. In 1976 they were simply stretches of DNA that encoded proteins. We now know about genes made of DNA’s cousin, RNA; we’ve discovered genes that hop from genome to genome
  • None of the complications of modern genomes erodes the central premise of the selfish gene.
  • Much of the enmity stems from people misunderstanding that selfishness is being used as a metaphor. The irony of these attacks is that the selfish gene metaphor actually explains altruism. We help others who are not directly related to us because we share similar versions of genes with them.
  • In the scientific community, the chief objection maintains that natural selection can operate at the level of a group of animals, not solely on genes or even individuals
  • To my mind, and that of the majority of evolutionary biologists, the gene-centric view of evolution always emerges intact.
  • the premise remains exciting that a gene’s only desire is to reproduce itself, and that the complexity of genomes makes that reproduction more efficient.

Hawaii: Where Evolution Can Be Surprisingly Predictable - The Atlantic - 0 views

  • Situated around 2,400 miles from the nearest continent, the Hawaiian Islands are about as remote as it’s possible for islands to be. In the last 5 million years, they’ve been repeatedly colonized by far-traveling animals, which then diversified into dozens of new species. Honeycreeper birds, fruit flies, carnivorous caterpillars ... all of these creatures reached Hawaii, and evolved into wondrous arrays of unique forms.
  • The most spectacular of these spider dynasties, Gillespie says, are the stick spiders. They’re so-named because some of them have long, distended abdomens that make them look like twigs. “You only see them at night, walking around the understory very slowly,” Gillespie says. “They’re kind of like sloths.” Murderous sloths, though: Their sluggish movements allow them to sneak up on other spiders and kill them.
  • Gillespie has shown that the gold spiders on Oahu belong to a different species from those on Kauai or Molokai. In fact, they’re more closely related to their brown and white neighbors from Oahu. Time and again, these spiders have arrived on new islands and evolved into new species—but always in one of three basic ways. A gold spider arrives on Oahu, and diversified into gold, brown, and white species. Another gold spider hops across to Maui and again diversified into gold, brown, and white species. “They repeatedly evolve the same forms,” says Gillespie.
  • ...3 more annotations...
  • Gillespie has seen this same pattern before, among Hawaii’s long-jawed goblin spiders. Each island has its own representatives of the four basic types: green, maroon, small brown, and large brown. At first, Gillespie assumed that all the green species were related to each other. But the spiders’ DNA revealed that the ones that live on the same islands are most closely related, regardless of their colors. They too have hopped from one island to another, radiating into the same four varieties wherever they land.
  • One of the most common misunderstandings about evolution is that it is a random process. Mutations are random, yes, but those mutations then rise and fall in ways that are anything but random. That’s why stick spiders, when they invade a new island, don’t diversify into red species, or zebra-striped ones. The environment of Hawaii sculpts their bodies in a limited number of ways.
  • Gillespie adds that there’s an urgency to this work. For millions of years, islands like Hawaii have acted as crucibles of evolution, allowing living things to replay evolution’s tape in the way that Gould envisaged. But in a much shorter time span, humans have threatened the results of those natural experiments. “The Hawaiian islands are in dire trouble from invasive species, and environmental modifications,” says Gillespie. “And you have all these unknown groups of spiders—entire lineages of really beautiful, charismatic animals, most of which are undescribed.”

Studying Recent Human Evolution at the Genetic Level - NYTimes.com - 1 views

  •  
    This article provided some interesting insight on how/why different races look the way they do. On one hand, genetic mutations are propagated because of distinct advantages; on the other hand, the more "attractive" traits are propagated, no necessarily because they make people survive longer, but because they increase the rate of mating. Like we discussed in the human sciences, the process of human evolution has multiple causation.

  • Theo and Robin have a nightly ritual where they say a prayer that Alyssa, the deceased wife and mother, taught them: May all sentient beings be free from needless suffering. That prayer itself comes from the four immeasurables in the Buddhist tradition.
  • When we enter into or recover this sense of kinship that was absolutely fundamental to so many indigenous cultures everywhere around the world at many, many different points in history, that there is no radical break between us and our kin, that even consciousness is shared, to some degree and to a large degree, with a lot of other creatures, then death stops seeming like the enemy and it starts seeming like one of the most ingenious kinds of design for keeping evolution circulating and keeping the experiment running and recombining.
  • Look, I’m 64 years old. I can remember sitting in psychology class as an undergraduate and having my professor declare that no, of course animals don’t have emotions because they don’t have an internal life. They don’t have conscious awareness. And so what looks to you like your dog being extremely happy or being extremely guilty, which dogs do so beautifully, is just your projection, your anthropomorphizing of those other creatures. And this prohibition against anthropomorphism created an artificial gulf between even those animals that are ridiculously near of kin to us, genetically.
  • ...62 more annotations...
  • I don’t know if that sounds too complicated. But the point is, it’s not just giving up domination. It’s giving up this sense of separateness in favor of a sense of kinship. And those people who do often wonder how they failed to see how much continuity there is in the more-than-human world with the human world.
  • to go from terror into being and into that sense that the experiment is sacred, not this one outcome of the experiment, is to immediately transform the way that you think even about very fundamental social and economic and cultural things. If the experiment is sacred, how can we possibly justify our food systems, for instance?
  • when I first went to the Smokies and hiked up into the old growth in the Southern Appalachians, it was like somebody threw a switch. There was some odd filter that had just been removed, and the world sounded different and smelled different.
  • richard powersYeah. In human exceptionalism, we may be completely aware of evolutionary continuity. We may understand that we have a literal kinship with the rest of creation, that all life on Earth employs the same genetic code, that there is a very small core of core genes and core proteins that is shared across all the kingdoms and phyla of life. But conceptually, we still have this demented idea that somehow consciousness creates a sanctity and a separation that almost nullifies the continuous elements of evolution and biology that we’ve come to understand.
  • if we want to begin this process of rehabilitation and transformation of consciousness that we are going to need in order to become part of the living Earth, it is going to be other kinds of minds that give us that clarity and strength and diversity and alternative way of thinking that could free us from this stranglehold of thought that looks only to the maximizing return on investment in very leverageable ways.
  • richard powersIt amazed me to get to the end of the first draft of “Bewilderment” and to realize how much Buddhism was in the book, from the simplest things.
  • I think there is nothing more science inflected than being out in the living world and the more-than-human world and trying to understand what’s happening.
  • And of course, we can combine this with what we were talking about earlier with death. If we see all of evolution as somehow leading up to us, all of human, cultural evolution leading up to neoliberalism and here we are just busily trying to accumulate and make meaning for ourselves, death becomes the enemy.
  • And you’re making the point in different ways throughout the book that it is the minds we think of as unusual, that we would diagnose as having some kind of problem or dysfunction that are, in some cases, are the only ones responding to the moment in the most common sense way it deserves. It is almost everybody else’s brain that has been broken.
  • it isn’t surprising. If you think of the characteristics of this dominant culture that we’ve been talking about — the fixation on control, the fixation on mastery, the fixation on management and accumulation and the resistance of decay — it isn’t surprising that that culture is also threatened by difference and divergence. It seeks out old, stable hierarchies — clear hierarchies — of control, and anything that’s not quite exploitable or leverageable in the way that the normal is terrifying and threatening.
  • And the more I looked for it, the more it pervaded the book.
  • ezra kleinI’ve heard you say that it has changed the way you measure a good day. Can you tell me about that?richard powersThat’s true.I suppose when I was still enthralled to commodity-mediated individualist market-driven human exceptionalism — we need a single word for this
  • And since moving to the Smokies and since publishing “The Overstory,” my days have been entirely inverted. I wake up, I go to the window, and I look outside. Or I step out onto the deck — if I haven’t been sleeping on the deck, which I try to do as much as I can in the course of the year — and see what’s in the air, gauge the temperature and the humidity and the wind and see what season it is and ask myself, you know, what’s happening out there now at 1,700 feet or 4,000 feet or 5,000 feet.
  • let me talk specifically about the work of a scientist who has herself just recently published a book. It’s Dr. Suzanne Simard, and the book is “Finding the Mother Tree.” Simard has been instrumental in a revolution in our way of thinking about what’s happening underground at the root level in a forest.
  • it was a moving moment for me, as an easterner, to stand up there and to say, this is what an eastern forest looks like. This is what a healthy, fully-functioning forest looks like. And I’m 56 years old, and I’d never seen it.
  • the other topics of that culture tend to circle back around these sorts of trends, human fascinations, ways of magnifying our throw weight and our ability and removing the last constraints to our desires and, in particular, to eliminate the single greatest enemy of meaning in the culture of the technological sublime that is, itself, such a strong instance of the culture of human separatism and commodity-mediated individualist capitalism— that is to say, the removal of death.
  • Why is it that we have known about the crisis of species extinction for at least half a century and longer? And I mean the lay public, not just scientists. But why has this been general knowledge for a long time without public will demanding some kind of action or change
  • And when you make kinship beyond yourself, your sense of meaning gravitates outwards into that reciprocal relationship, into that interdependence. And you know, it’s a little bit like scales falling off your eyes. When you do turn that corner, all of the sources of anxiety that are so present and so deeply internalized become much more identifiable. And my own sense of hope and fear gets a much larger frame of reference to operate in.
  • I think, for most of my life, until I did kind of wake up to forests and to trees, I shared — without really understanding this as a kind of concession or a kind of subscription — I did share this cultural consensus that meaning is a private thing that we do for ourselves and by ourselves and that our kind of general sense of the discoveries of the 19th and 20th century have left us feeling a bit unsponsored and adrift beyond the accident of human existence.
  • The largest single influence on any human being’s mode of thought is other human beings. So if you are surrounded by lots of terrified but wishful-thinking people who want to believe that somehow the cavalry is going to come at the last minute and that we don’t really have to look inwards and change our belief in where meaning comes from, that we will somehow be able to get over the finish line with all our stuff and that we’ll avert this disaster, as we have other kinds of disasters in the past.
  • I think what was happening to me at that time, as I was turning outward and starting to take the non-human world seriously, is my sense of meaning was shifting from something that was entirely about me and authored by me outward into this more collaborative, reciprocal, interdependent, exterior place that involved not just me but all of these other ways of being that I could make kinship with.
  • And I think I was right along with that sense that somehow we are a thing apart. We can make purpose and make meaning completely arbitrarily. It consists mostly of trying to be more in yourself, of accumulating in one form or another.
  • I can’t really be out for more than two or three miles before my head just fills with associations and ideas and scenes and character sketches. And I usually have to rush back home to keep it all in my head long enough to get it down on paper.
  • for my journey, the way to characterize this transition is from being fascinated with technologies of mastery and control and what they’re doing to us as human beings, how they’re changing what the capacities and affordances of humanity are and how we narrate ourselves, to being fascinated with technologies and sciences of interdependence and cooperation, of those sciences that increase our sense of kinship and being one of many, many neighbors.
  • And that’s an almost impossible persuasion to rouse yourself from if you don’t have allies. And I think the one hopeful thing about the present is the number of people trying to challenge that consensual understanding and break away into a new way of looking at human standing is growing.
  • And when you do subscribe to a culture like that and you are confronted with the reality of your own mortality, as I was when I was living in Stanford, that sense of stockpiling personal meaning starts to feel a little bit pointless.
  • And I just head out. I head out based on what the day has to offer. And to have that come first has really changed not only how I write, but what I’ve been writing. And I think it really shows in “Bewilderment.” It’s a totally different kind of book from my previous 12.
  • the marvelous thing about the work, which continues to get more sophisticated and continues to turn up newer and newer astonishments, is that there was odd kind of reciprocal interdependence and cooperation across the species barrier, that Douglas firs and birches were actually involved in these sharing back and forth of essential nutrients. And that’s a whole new way of looking at forest.
  • she began to see that the forests were actually wired up in very complex and identifiable ways and that there was an enormous system of resource sharing going on underground, that trees were sharing not only sugars and the hydrocarbons necessary for survival, but also secondary metabolites. And these were being passed back and forth, both symbiotically between the trees and the fungi, but also across the network to other trees so that there were actually trees in wired up, fungally-connected forests where large, dominant, healthy trees were subsidizing, as it were, trees that were injured or not in favorable positions or damaged in some way or just failing to thrive.
  • so when I was still pretty much a card-carrying member of that culture, I had this sense that to become a better person and to get ahead and to really make more of myself, I had to be as productive as possible. And that meant waking up every morning and getting 1,000 words that I was proud of. And it’s interesting that I would even settle on a quantitative target. That’s very typical for that kind of mindset that I’m talking about — 1,000 words and then you’re free, and then you can do what you want with the day.
  • there will be a threshold, as there have been for these other great social transformations that we’ve witnessed in the last couple of decades where somehow it goes from an outsider position to absolutely mainstream and common sense.
  • I am persuaded by those scholars who have showed the degree to which the concept of nature is itself an artificial construction that’s born of cultures of human separatism. I believe that everything that life does is part of the living enterprise, and that includes the construction of cities. And there is no question at all the warning that you just gave about nostalgia creating a false binary between the built world and the true natural world is itself a form of cultural isolation.
  • Religion is a technology to discipline, to discipline certain parts of the human impulse. A lot of the book revolves around the decoded neurofeedback machine, which is a very real literalization of a technology, of changing the way we think
  • one of the things I think that we have to take seriously is that we have created technologies to supercharge some parts of our natural impulse, the capitalism I think should be understood as a technology to supercharge the growth impulse, and it creates some wonders out of that and some horrors out of that.
  • richard powersSure. I base my machine on existing technology. Decoded neurofeedback is a kind of nascent field of exploration. You can read about it; it’s been publishing results for a decade. I first came across it in 2013. It involves using fMRI to record the brain activity of a human being who is learning a process, interacting with an object or engaged in a certain emotional state. That neural activity is recorded and stored as a data structure. A second subsequent human being is then also scanned in real time and fed kinds of feedback based on their own internal neural activity as determined by a kind of software analysis of their fMRI data structures.
  • And they are queued little by little to approximate, to learn how to approximate, the recorded states of the original subject. When I first read about this, I did get a little bit of a revelation. I did feel my skin pucker and think, if pushed far enough, this would be something like a telepathy conduit. It would be a first big step in answering that age-old question of what does it feel like to be something other than we are
  • in the book I simply take that basic concept and extend it, juke it up a little bit, blur the line between what the reader might think is possible right now and what they might wonder about, and maybe even introduce possibilities for this empathetic transference
  • ezra kleinOne thing I loved about the role this played in the book is that it’s highlighting its inverse. So a reader might look at this and say, wow, wouldn’t that be cool if we had a machine that could in real time change how we think and change our neural pathways and change our mental state in a particular direction? But of course, all of society is that machine,
  • Robin and Theo are in an airport. And you’ve got TVs everywhere playing the news which is to say playing a constant loop of outrage, and disaster, and calamity. And Robbie, who’s going through these neural feedback sessions during this period, turns to his dad and says, “Dad, you know how the training’s rewiring my brain? This is what is rewiring everybody else.”
  • ezra kleinI think Marshall McLuhan knew it all. I really do. Not exactly what it would look like, but his view and Postman’s view that we are creating a digital global nervous system is a way they put it, it was exactly right. A nervous system, it was such the exact right metaphor.
  • the great insight of McLuhan, to me, what now gets called the medium is the message is this idea that the way media acts upon us is not in the content it delivers. The point of Twitter is not the link that you click or even the tweet that you read; it is that the nature and structure of the Twitter system itself begins to act on your system, and you become more like it.If you watch a lot of TV, you become more like TV. If you watch a lot of Twitter, you become more like Twitter, Facebook more like Facebook. Your identities become more important to you — that the content is distraction from the medium, and the medium changes you
  • it is happening to all of us in ways that at least we are not engaging in intentionally, not at that level of how do we want to be transformed.
  • richard powersI believe that the digital neural system is now so comprehensive that the idea that you could escape it somewhere, certainly not in the Smokies, even more remotely, I think, becomes more and more laughable. Yeah, and to build on this idea of the medium being the message, not the way in which we become more like the forms and affordances of the medium is that we begin to expect that those affordances, the method in which those media are used, the physiological dependencies and castes of behavior and thought that are required to operate them and interact with them are actual — that they’re real somehow, and that we just take them into human nature and say no, this is what we’ve always wanted and we’ve simply been able to become more like our true selves.
  • Well, the warpage in our sense of time, the warpage in our sense of place, are profound. The ways in which digital feedback and the affordances of social media and all the rest have changed our expectations with regard to what we need to concentrate on, what we need to learn for ourselves, are changing profoundly.
  • If you look far enough back, you can find Socrates expressing great anxiety and suspicion about the ways in which writing is going to transform the human brain and human expectation. He was worried that somehow it was going to ruin our memories. Well, it did up to a point — nothing like the way the digital technologies have ruined our memories.
  • my tradition is Jewish, the Sabbath is a technology, is a technology to create a different relationship between the human being, and time, and growth, and productive society than you would have without the Sabbath which is framed in terms of godliness but is also a way of creating separation from the other impulses of the weak.
  • Governments are a technology, monogamy is a technology, a religiously driven technology, but now one that is culturally driven. And these things do good and they do bad. I’m not making an argument for any one of them in particular. But the idea that we would need to invent something wholly new to come up with a way to change the way human beings act is ridiculous
  • My view of the story of this era is that capitalism was one of many forces, and it has become, in many societies, functionally the only one that it was in relationship with religion, it was in relationship with more rooted communities.
  • it has become not just an economic system but a belief system, and it’s a little bit untrammeled. I’m not an anti-capitalist person, but I believe it needs countervailing forces. And my basic view is that it doesn’t have them anymore.
  • the book does introduce this kind of fable, this kind of thought experiment about the way the affordances that a new and slightly stronger technology of empathy might deflect. First of all, the story of a little boy and then the story of his father who’s scrambling to be a responsible single parent. And then, beyond that, the community of people who hear about this boy and become fascinated with him as a narrative, which again ripples outward through these digital technologies in ways that can’t be controlled or whose consequences can be foreseen.
  • I’ve talked about it before is something I’ve said is that I think a push against, functionally, materialism and want is an important weight in our society that we need. And when people say it is the way we’ll deal with climate change in the three to five year time frame, I become much more skeptical because to the point of things like the technology you have in the book with neural feedback, I do think one of the questions you have to ask is, socially and culturally, how do you move people’s minds so you can then move their politics?
  • You’re going to need something, it seems to me, outside of politics, that changes humans’ sense of themselves more fundamentally. And that takes a minute at the scale of billions.
  • richard powersWell, you are correct. And I don’t think it’s giving away any great reveal in the book to say that a reader who gets far enough into the story probably has this moment of recursive awareness where they, he or she comes to understand that what Robin is doing in this gradual training on the cast of mind of some other person is precisely what they’re doing in the act of reading the novel “Bewilderment” — by living this act of active empathy for these two characters, they are undergoing their own kind of neurofeedback.
  • The more we understand about the complexities of living systems, of organisms and the evolution of organisms, the more capable it is to feel a kind of spiritual awe. And that certainly makes it easier to have reverence for the experiment beyond me and beyond my species. I don’t think those are incommensurable or incompatible ways of knowing the world. In fact, I think to invoke one last time that Buddhist precept of interbeing, I think there is a kind of interbeing between the desire, the true selfless desire to understand the world out there through presence, care, measurement, attention, reproduction of experiment and the desire to have a spiritual affinity and shared fate with the world out there. They’re really the same project.
  • richard powersWell, sure. If we turn back to the new forestry again and researchers like Suzanne Simard who were showing the literal interconnectivity across species boundaries and the cooperation of resource sharing between different species in a forest, that is rigorous science, rigorous reproducible science. And it does participate in that central principle of practice, or collection of practices, which always requires the renunciation of personal wish and ego and prior belief in favor of empirical reproduction.
  • I’ve begun to see people beginning to build out of the humbling sciences a worldview that seems quite spiritual. And as you’re somebody who seems to me to have done that and it has changed your life, would you reflect on that a bit?
  • So much of the book is about the possibility of life beyond Earth. Tell me a bit about the role that’s playing. Why did you make the possibility of alien life in the way it might look and feel and evolve and act so central in a book about protecting and cherishing life here?
  • richard powersI’m glad that we’re slipping this in at the end because yes this framing of the book around this question of are we alone or does the universe want life it’s really important. Theo, Robin’s father, is an astrobiologist.
  • Imagine that everything happens just right so that every square inch of this place is colonized by new forms of experiments, new kinds of life. And the father trying to entertain his son with the story of this remarkable place in the sun just stopping him and saying, Dad, come on, that’s asking too much. Get real, that’s science fiction. That’s the vision that I had when I finished the book, an absolutely limitless sense of just how lucky we’ve had it here.
  • one thing I kept thinking about that didn’t make it into the final book but exists as a kind of parallel story in my own head is the father and son on some very distant planet in some very distant star, many light years from here, playing that same game. And the father saying, OK, now imagine a world that’s just the right size, and it has plate tectonics, and it has water, and it has a nearby moon to stabilize its rotation, and it has incredible security and safety from asteroids because of other large planets in the solar system.
  • they make this journey across the universe through all kinds of incubators, all kinds of petri dishes for life and the possibilities of life. And rather than answer the question — so where is everybody? — it keeps deferring the question, it keeps making that question more subtle and stranger
  • For the purposes of the book, Robin, who desperately believes in the sanctity of life beyond himself, begs his father for these nighttime, bedtime stories, and Theo gives him easy travel to other planets. Father and son going to a new planet based on the kinds of planets that Theo’s science is turning up and asking this question, what would life look like if it was able to get started here?

God, Darwin and My College Biology Class - NYTimes.com - 0 views

  • There are a few ways to talk about evolution and religion, I begin. The least controversial is to suggest that they are in fact compatible. Stephen Jay Gould called them “nonoverlapping magisteria,” noma for short, with the former concerned with values and the latter with facts.
  • Noma is the received wisdom in the scientific establishment, including institutions like the National Center for Science Education, which has done much heavy lifting when it comes to promoting public understanding and acceptance of evolution. According to this expansive view, God might well have used evolution by natural selection to produce his creation.
  • This is undeniable. If God exists, then he could have employed anything under the sun — or beyond it — to work his will. Hence, there is nothing in evolutionary biology that necessarily precludes religion, save for most religious fundamentalisms
  • ...4 more annotations...
  • here’s the turn: These magisteria are not nearly as nonoverlapping as some of them might wish.
  • As evolutionary science has progressed, the available space for religious faith has narrowed: It has demolished two previously potent pillars of religious faith and undermined belief in an omnipotent and omni-benevolent God.
  • The more we know of evolution, the more unavoidable is the conclusion that living things, including human beings, are produced by a natural, totally amoral process, with no indication of a benevolent, controlling creator.
  • I CONCLUDE The Talk by saying that, although they don’t have to discard their religion in order to inform themselves about biology (or even to pass my course), if they insist on retaining and respecting both, they will have to undertake some challenging mental gymnastic routines.

  • The study found that conservatives tend to distrust science on issues such as climate change and evolution. For liberals, it is fracking and nuclear power.

An Extinct, Head-Butting Animal May Help Explain Giraffes' Long Necks | Smart News| Smi... - 0 views

  • Charles Darwin held up giraffes as a prime example of natural selection, his theory that’s often summarized as “survival of the fittest.” Giraffes with comparably longer necks could reach food high up in trees, which gave them an advantage over other animals and members of their own species with shorter necks. These longer-necked individuals thrived and reproduced more, leading to generations of giraffes with their signature lengthened anatomy.
  • Yes, giraffes may have evolved to be able to reach food at higher elevations, but their long necks may also be the result of fierce competition for mates
  • For many years, researchers simply called the mysterious animal “guài shòu,” or “strange beast.” Now, scientists have given the mammal a name—Discokeryx xiezhi—and they’ve pieced together a rough outline of how the animal may have lived some 16.9 million years ago.

  • Discokeryx xiezhi was an early relative of today’s giraffes, but more like a cousin and not a direct ancestor.
  • “To the best of our knowledge, D. xiezhi exhibits the most optimized head-butting adaptation in vertebrate evolution,” the researchers write in the paper.
  • The discovery of Discokeryx xiezhi suggests this fighting style and competition for mates may be a contributing factor in their long-neck evolution.
  • “In reality, it was likely a combination of natural selection ... for a particular dietary preference and sexual selection in that lineage that drove the evolution of modern giraffe necks and limbs,” Advait Jukar, a paleobiologist at Yale University who was not involved in the study tells Scientific American’s Rachel Nuwer.

The "missing law" of nature was here all along | Salon.com - 0 views

  • recently published scientific article proposes a sweeping new law of nature, approaching the matter with dry, clinical efficiency that still reads like poetry.
  • “Evolving systems are asymmetrical with respect to time; they display temporal increases in diversity, distribution, and/or patterned behavior,” they continue, mounting their case from the shoulders of Charles Darwin, extending it toward all things living and not. 
  • To join the known physics laws of thermodynamics, electromagnetism and Newton’s laws of motion and gravity, the nine scientists and philosophers behind the paper propose their “law of increasing functional information.”
  • ...27 more annotations...
  • In short, a complex and evolving system — whether that’s a flock of gold finches or a nebula or the English language — will produce ever more diverse and intricately detailed states and configurations of itself.
  • Some of these more diverse and intricate configurations, the scientists write, are shed and forgotten over time. The configurations that persist are ones that find some utility or novel function in a process akin to natural selection, but a selection process driven by the passing-on of information rather than just the sowing of biological genes
  • Have they finally glimpsed, I wonder, the connectedness and symbiotic co-evolution of their own scientific ideas with those of the world’s writers
  • Have they learned to describe in their own quantifying language that cradle from which both our disciplines have emerged and the firmament on which they both stand — the hearing and telling of stories in order to exist?
  • Have they quantified the quality of all existent matter, living and not: that all things inherit a story in data to tell, and that our stories are told by the very forms we take to tell them? 
  • “Is there a universal basis for selection? Is there a more quantitative formalism underlying this conjectured conceptual equivalence—a formalism rooted in the transfer of information?,” they ask of the world’s disparate phenomena. “The answer to both questions is yes.”
  • In her Pulitzer-winning “Pilgrim at Tinker Creek,” nature writer Annie Dillard explains plainly that evolution is the vehicle of such intricacy in the natural world, as much as it is in our own thoughts and actions. 
  • The principle of complexity evolving at its own pace when left to its own devices, independent of time but certainly in a dance with it, is nothing new. Not in science, nor in its closest humanities kin, science and nature writing. Give things time and nourishing environs, protect them from your own intrusions and — living organisms or not — they will produce abundant enlacement of forms.
  • This is how poetry was born from the same larynxes and phalanges that tendered nuclear equations: We featherless bipeds gave language our time and delighted attendance until its forms were so multivariate that they overflowed with inevitable utility.
  • Yes. They’ve glimpsed it, whether they know it or not. Sing to me, O Muse, of functional information and its complex diversity.
  • “The stability of simple forms is the sturdy base from which more complex, stable forms might arise, forming in turn more complex forms,” she explains, drawing on the undercap frills of mushrooms and filament-fine filtering tubes inside human kidneys to illustrate her point. 
  • “Utility to the creature is evolution’s only aesthetic consideration. Form follows function in the created world, so far as I know, and the creature that functions, however bizarre, survives to perpetuate its form,” writes Dillard.
  • Or, as the Mishna would have it, “the creations were all made in generic form, and they gradually expanded.” 
  • She notes that, of all forms of life we’ve ever known to exist, only about 10% are still alive. What extravagant multiplicity. 
  • “Intricacy is that which is given from the beginning, the birthright, and in the intricacy is the hardiness of complexity that ensures against the failures of all life,” Dillard writes. “The wonder is — given the errant nature of freedom and the burgeoning texture of time — the wonder is that all the forms are not monsters, that there is beauty at all, grace gratuitous.”
  • “This paper, and the reason why I'm so proud of it, is because it really represents a connection between science and the philosophy of science that perhaps offers a new lens into why we see everything that we see in the universe,” lead scientist Michael Wong told Motherboard in a recent interview. 
  • Wong is an astrobiologist and planetary scientist at the Carnegie Institute for Science. In his team’s paper, that bridge toward scientific philosophy is not only preceded by a long history of literary creativity but directly theorizes about the creative act itself.  
  • “The creation of art and music may seem to have very little to do with the maintenance of society, but their origins may stem from the need to transmit information and create bonds among communities, and to this day, they enrich life in innumerable ways,” Wong’s team writes.  
  • “Perhaps, like eddies swirling off of a primary flow field, selection pressures for ancillary functions can become so distant from the core functions of their host systems that they can effectively be treated as independently evolving systems,” the authors add, pointing toward the elaborate mating dance culture observed in birds of paradise.
  • “Perhaps it will be humanity’s ability to learn, invent, and adopt new collective modes of being that will lead to its long-term persistence as a planetary phenomenon. In light of these considerations, we suspect that the general principles of selection and function discussed here may also apply to the evolution of symbolic and social systems.”
  • The Mekhilta teaches that all Ten Commandments were pronounced in a single utterance. Similarly, the Maharsha says the Torah’s 613 mitzvoth are only perceived as a plurality because we’re time-bound humans, even though they together form a singular truth which is indivisible from He who expressed it. 
  • “Of the multiplicity of forms, I know nothing. Except that, apparently, anything goes. This holds for forms of behavior as well as design — the mantis munching her mate, the frog wintering in mud.” 
  • Like swirling eddies off of a primary flow field.
  • “O Lord, how manifold are thy works!,” cried out David in his psalm. “In wisdom hast thou made them all: the earth is full of thy riches. So is this great and wide sea, wherein are things creeping innumerable, both small and great beasts.” 
  • Because, whether wittingly or not, science is singing the tune of the humanities. And whether expressed in algebraic logic or ancient Greek hymn, its chorus is the same throughout the universe: Be fruitful and multiply. 
  • In all things, then — from poetic inventions, to rare biodiverse ecosystems, to the charted history of our interstellar equations — it is best if we conserve our world’s intellectual and physical diversity, for both the study and testimony of its immeasurable multiplicity.
  • Both intricate configurations of art and matter arise and fade according to their shared characteristic, long-known by students of the humanities: each have been graced with enough time to attend to the necessary affairs of their most enduring pleasures.
