"A curious aspect of the theory of evolution," said Jacques Monod, "is that everybody thinks he understands it."

    A human being, looking at the natural world, sees a thousand times purpose. A rabbit's legs, built and articulated for running; a fox's jaws, built and articulated for tearing. But what you see is not exactly what is there...

    In the days before Darwin, the cause of all this apparent purposefulness was a very great puzzle unto science. The Goddists said "God did it", because you get 50 bonus points each time you use the word "God" in a sentence. Yet perhaps I'm being unfair. In the days before Darwin, it seemed like a much more reasonable hypothesis. Find a watch in the desert, said William Paley, and you can infer the existence of a watchmaker.

    But when you look at all the apparent purposefulness in Nature, rather than picking and choosing your examples, you start to notice things that don't fit the Judeo-Christian concept of one benevolent God. Foxes seem well-designed to catch rabbits. Rabbits seem well-designed to evade foxes. Was the Creator having trouble making up Its mind?

    When I design a toaster oven, I don't design one part that tries to get electricity to the coils and a second part that tries to prevent electricity from getting to the coils. It would be a waste of effort. Who designed the ecosystem, with its predators and prey, viruses and bacteria? Even the cactus plant, which you might think well-designed to provide water fruit to desert animals, is covered with inconvenient spines.

    The ecosystem would make much more sense if it wasn't designed by a unitary Who, but, rather, created by a horde of deities—say from the Hindu or Shinto religions. This handily explains both the ubiquitous purposefulnesses, and the ubiquitous conflicts: More than one deity acted, often at cross-purposes. The fox and rabbit were both designed, but by distinct competing deities. I wonder if anyone ever remarked on the seemingly excellent evidence thus provided for Hinduism over Christianity. Probably not.

    Similarly, the Judeo-Christian God is alleged to be benevolent—well, sort of. And yet much of nature's purposefulness seems downright cruel. Darwin suspected a non-standard Creator for studying Ichneumon wasps, whose paralyzing stings preserve its prey to be eaten alive by its larvae: "I cannot persuade myself," wrote Darwin, "that a beneficent and omnipotent God would have designedly created the Ichneumonidae with the express intention of their feeding within the living bodies of Caterpillars, or that a cat should play with mice." I wonder if any earlier thinker remarked on the excellent evidence thus provided for Manichaen religions over monotheistic ones.

    By now we all know the punchline: You just say "evolution".

    I worry that's how some people are absorbing the "scientific" explanation, as a magical purposefulness factory in Nature. I've previously discussed the case of Storm from the movie X-Men, who in one mutation gets the ability to throw lightning bolts. Why? Well, there's this thing called "evolution" that somehow pumps a lot of purposefulness into Nature, and the changes happen through "mutations". So if Storm gets a really large mutation, she can be redesigned to throw lightning bolts. Radioactivity is a popular super origin: radiation causes mutations, so more powerful radiation causes more powerful mutations. That's logic.

    But evolution doesn't allow just any kind of purposefulness to leak into Nature. That's what makes evolution a success as an empirical hypothesis. If evolutionary biology could explain a toaster oven, not just a tree, it would be worthless. There's a lot more to evolutionary theory than pointing at Nature and saying, "Now purpose is allowed," or "Evolution did it!" The strength of a theory is not what it allows, but what it prohibits; if you can invent an equally persuasive explanation for any outcome, you have zero knowledge.

    "Many non-biologists," observed George Williams, "think that it is for their benefit that rattles grow on rattlesnake tails." Bzzzt! This kind of purposefulness is not allowed. Evolution doesn't work by letting flashes of purposefulness creep in at random—reshaping one species for the benefit of a random recipient.

    Evolution is powered by a systematic correlation between the different ways that different genes construct organisms, and how many copies of those genes make it into the next generation. For rattles to grow on rattlesnake tails, rattle-growing genes must become more and more frequent in each successive generation. (Actually genes for incrementally more complex rattles, but if I start describing all the fillips and caveats to evolutionary biology, we really will be here all day.)

    There isn't an Evolution Fairy that looks over the current state of Nature, decides what would be a "good idea", and chooses to increase the frequency of rattle-constructing genes.

    I suspect this is where a lot of people get stuck, in evolutionary biology. They understand that "helpful" genes become more common, but "helpful" lets any sort of purpose leak in. They don't think there's an Evolution Fairy, yet they ask which genes will be "helpful" as if a rattlesnake gene could "help" non-rattlesnakes.

    The key realization is that there is no Evolution Fairy. There's no outside force deciding which genes ought to be promoted. Whatever happens, happens because of the genes themselves.

    Genes for constructing (incrementally better) rattles, must have somehow ended up more frequent in the rattlesnake gene pool, because of the rattle. In this case it's probably because rattlesnakes with better rattles survive more often—rather than mating more successfully, or having brothers that reproduce more successfully, etc.

    Maybe predators are wary of rattles and don't step on the snake. Or maybe the rattle diverts attention from the snake's head. (As George Williams suggests, "The outcome of a fight between a dog and a viper would depend very much on whether the dog initially seized the reptile by the head or by the tail.")

    But that's just a snake's rattle. There are much more complicated ways that a gene can cause copies of itself to become more frequent in the next generation. Your brother or sister shares half your genes. A gene that sacrifices one unit of resources to bestow three units of resource on a brother, may promote some copies of itself by sacrificing one of its constructed organisms. (If you really want to know all the details and caveats, buy a book on evolutionary biology; there is no royal road.)

    The main point is that the gene's effect must cause copies of that gene to become more frequent in the next generation. There's no Evolution Fairy that reaches in from outside. There's nothing which decides that some genes are "helpful" and should, therefore, increase in frequency. It's just cause and effect, starting from the genes themselves.

    This explains the strange conflicting purposefulness of Nature, and its frequent cruelty. It explains even better than a horde of Shinto deities.

    Why is so much of Nature at war with other parts of Nature? Because there isn't one Evolution directing the whole process. There's as many different "evolutions" as reproducing populations. Rabbit genes are becoming more or less frequent in rabbit populations. Fox genes are becoming more or less frequent in fox populations. Fox genes which construct foxes that catch rabbits, insert more copies of themselves in the next generation. Rabbit genes which construct rabbits that evade foxes are naturally more common in the next generation of rabbits. Hence the phrase "natural selection".

    Why is Nature cruel? You, a human, can look at an Ichneumon wasp, and decide that it's cruel to eat your prey alive. You can decide that if you're going to eat your prey alive, you can at least have the decency to stop it from hurting. It would scarcely cost the wasp anything to anesthetize its prey as well as paralyze it. Or what about old elephants, who die of starvation when their last set of teeth fall out? These elephants aren't going to reproduce anyway. What would it cost evolution—the evolution of elephants, rather—to ensure that the elephant dies right away, instead of slowly and in agony? What would it cost evolution to anesthetize the elephant, or give it pleasant dreams before it dies? Nothing; that elephant won't reproduce more or less either way.

    If you were talking to a fellow human, trying to resolve a conflict of interest, you would be in a good negotiating position—would have an easy job of persuasion. It would cost so little to anesthetize the prey, to let the elephant die without agony! Oh please, won't you do it, kindly... um...

    There's no one to argue with.

    Human beings fake their justifications, figure out what they want using one method, and then justify it using another method. There's no Evolution of Elephants Fairy that's trying to (a) figure out what's best for elephants, and then (b) figure out how to justify it to the Evolutionary Overseer, who (c) doesn't want to see reproductive fitness decreased, but is (d) willing to go along with the painless-death idea, so long as it doesn't actually harm any genes.

    There's no advocate for the elephants anywhere in the system.

    Humans, who are often deeply concerned for the well-being of animals, can be very persuasive in arguing how various kindnesses wouldn't harm reproductive fitness at all. Sadly, the evolution of elephants doesn't use a similar algorithm; it doesn't select nice genes that can plausibly be argued to help reproductive fitness. Simply: genes that replicate more often become more frequent in the next generation. Like water flowing downhill, and equally benevolent.

    A human, looking over Nature, starts thinking of all the ways we would design organisms. And then we tend to start rationalizing reasons why our design improvements would increase reproductive fitness—a political instinct, trying to sell your own preferred option as matching the boss's favored justification.

    And so, amateur evolutionary biologists end up making all sorts of wonderful and completely mistaken predictions. Because the amateur biologists are drawing their bottom line—and more importantly, locating their prediction in hypothesis-space—using a different algorithm than evolutions use to draw their bottom lines.

    A human engineer would have designed human taste buds to measure how much of each nutrient we had, and how much we needed. When fat was scarce, almonds or cheeseburgers would taste delicious. But if you started to become obese, or if vitamins were lacking, lettuce would taste delicious. But there is no Evolution of Humans Fairy, which intelligently planned ahead and designed a general system for every contingency. It was a reliable invariant of humans' ancestral environment that calories were scarce. So genes whose organisms loved calories, became more frequent. Like water flowing downhill.

    We are simply the embodied history of which organisms did in fact survive and reproduce, not which organisms ought prudentially to have survived and reproduced.

    The human retina is constructed backward: The light-sensitive cells are at the back, and the nerves emerge from the front and go back through the retina into the brain. Hence the blind spot. To a human engineer, this looks simply stupid—and other organisms have independently evolved retinas the right way around. Why not redesign the retina?

    The problem is that no single mutation will reroute the whole retina simultaneously. A human engineer can redesign multiple parts simultaneously, or plan ahead for future changes. But if a single mutation breaks some vital part of the organism, it doesn't matter what wonderful things a Fairy could build on top of it—the organism dies and the genes decreases in frequency.

    If you turn around the retina's cells without also reprogramming the nerves and optic cable, the system as a whole won't work. It doesn't matter that, to a Fairy or a human engineer, this is one step forward in redesigning the retina. The organism is blind. Evolution has no foresight, it is simply the frozen history of which organisms did in fact reproduce. Evolution is as blind as a halfway-redesigned retina.

    Find a watch in a desert, said William Paley, and you can infer the watchmaker. There were once those who denied this, who thought that life "just happened" without need of an optimization process, mice being spontaneously generated from straw and dirty shirts.

    If we ask who was more correct—the theologians who argued for a Creator-God, or the intellectually unfulfilled atheists who argued that mice spontaneously generated—then the theologians must be declared the victors: evolution is not God, but it is closer to God than it is to pure random entropy. Mutation is random, but selection is non-random. This doesn't mean an intelligent Fairy is reaching in and selecting. It means there's a non-zero statistical correlation between the gene and how often the organism reproduces. Over a few million years, that non-zero statistical correlation adds up to something very powerful. It's not a god, but it's more closely akin to a god than it is to snow on a television screen.

    In a lot of ways, evolution is like unto theology. "Gods are ontologically distinct from creatures," said Damien Broderick, "or they're not worth the paper they're written on." And indeed, the Shaper of Life is not itself a creature. Evolution is bodiless, like the Judeo-Christian deity. Omnipresent in Nature, immanent in the fall of every leaf. Vast as a planet's surface. Billions of years old. Itself unmade, arising naturally from the structure of physics. Doesn't that all sound like something that might have been said about God?

    And yet the Maker has no mind, as well as no body. In some ways, its handiwork is incredibly poor design by human standards. It is internally divided. Most of all, it isn't nice.

    In a way, Darwin discovered God—a God that failed to match the preconceptions of theology, and so passed unheralded. If Darwin had discovered that life was created by an intelligent agent—a bodiless mind that loves us, and will smite us with lightning if we dare say otherwise—people would have said "My gosh! That's God!"

    But instead Darwin discovered a strange alien God—not comfortably "ineffable", but really genuinely different from us. Evolution is not a God, but if it were, it wouldn't be Jehovah. It would be H. P. Lovecraft's Azathoth, the blind idiot God burbling chaotically at the center of everything, surrounded by the thin monotonous piping of flutes.

    Which you might have predicted, if you had really looked at Nature.

    So much for the claim some religionists make, that they believe in a vague deity with a correspondingly high probability. Anyone who really believed in a vague deity, would have recognized their strange inhuman creator when Darwin said "Aha!"

    So much for the claim some religionists make, that they are waiting innocently curious for Science to discover God. Science has already discovered the sort-of-godlike maker of humans—but it wasn't what the religionists wanted to hear. They were waiting for the discovery of their God, the highly specific God they want to be there. They shall wait forever, for the great discovery has already taken place, and the winner is Azathoth.

    Well, more power to us humans. I like having a Creator I can outwit. Beats being a pet. I'm glad it was Azathoth and not Odin.

    I wonder if anyone ever remarked on the seemingly excellent evidence thus provided for Hinduism over Christianity. Probably not.

    Well, David Hume did. In the Dialogues Concerning Natural Religion. Although not with a totally straight face.

    The best book-long treatise about your points is probably Dawkins' The Selfish Gene. But you probably know that.

    7Delta12y
    I started on The Selfish Gene recently and it is a real revelation. It's going to take a lot of getting used to to think of myself as a "mere" machine to ensure the continuation of my genes. Once humans cease to be special, somehow above and apart from the world that built them you have to start rethinking a lot of your assumptions.

    Maybe predators are wary of rattles and don't step on the snake. Or maybe the rattle diverts attention from the snake's head.

    The point of a rattle, as I understand it, is that it's metabolically expensive, and time consuming, to produce poison. A snake that can chase off a dozen threats a day by wagging its tail is much better off probability-of-producing-offspring-wise than one that can only bite and poison three threats before being left defenseless for a few days.

    It does leave me wondering what benefits the intermediate mutations provide though, since going from a normal snake tail to a rattle seems like it would take more than one step.

    I have observed that more ordinary snakes that have not developed a rattle often vibrate their tail in a similar manner, which often makes a warning buzz that is merely somewhat quieter than a rattlesnake's rattle. So incremental improvements to this rattling mechanism, which started with a regular tail, would just slowly increase the loudness, and thus warning ability, of a snake's tail.

    1Larks14y
    Alternatively, maybe the buzz attracts attention away from the head of the snake, making it easier to attack.
    1puls14y
    Yes, and it would sustain less critical damage. I'm sure that both benefits contribute to the preservation of tail-rattling traits.

    All of these sound like a posteriori justifications than a priori predictions. Good ones. But still.

    That's kind of the point of this article. Evolution doesn't "choose" something, it just has changes happen, and if, like a rattle happening to scare off threats or reduce lethal damage, it aids survival, then it increases in the population.

    4sboo10y
    even if poison were cheap, every fight has a risk. better to neither fight nor flee.
    1tlhonmey2y
    Intermediate mutations don't necessarily need to provide any benefit at all, they just need to not have any detrimental effects. As I recall, a rattlesnake's rattles are formed more-or-less by its skin failing to shed perfectly cleanly.  That costs practically nothing and is exactly the kind of weird mutation that can crop up in an isolated segment of the population where it doesn't take long for genes to stabilize. Then the isolation ends, and it turns out that the weird new trait has some amount of benefit over the population at large, so it spreads.

    I'm not convinced that evolution is closer to "god" than to pure entropy. Really, the Tegmark big universe seems much closer to both "god" and pure entropy than evolution does, and may be a necessary creator for life as well, though it's still possible the evolution can do the whole job itself. Evolution has this whole "embedded in time" schtick going on that definitely makes it more like "gods" than like "god", as you observed.

    Eliezer,

    You say: "if you can invent an equally persuasive explanation for any outcome, you have zero knowledge."

    You'll want to read Quine on this. Quine thought that for nearly any sufficiently large data set there were an infinite number of theories that could accurately explain it. Now, granted, some theories are better than others, but many theories are harder to compare with others. Here are some examples:

    Suppose you have three theoretical values: simplicity, coherence, and accommodation of the data. Different parts of a given scientific comm... (read more)

    3SilasBarta14y
    A lot of people, including me, seem to have been brought to this old discussion recently, and I think it's an interesting coincidence that I just today made this comment, which doubles as a response to selfreferencing here. I would add that "simplicity, coherence, and accommodation of the data" are not independent -- they can all fit into one metric, that of the shortness of the message needed to reproduce the data. Coherence is accounted for by how you have list any contradictions as exceptions to posited rules. Accommodation of the data is accounted for in that you have to reproduce all of the data, via generating algorithm or by restating it. Simplicity, of course, is inherent in the requirement of minimal length.

    Jannia, the poison-delivery-method is pretty complex, too. It's amazing they didn't develop a stinger, or legs, as well. They had to have a gland to produce the poison, a sac to store it, and the hypodermic needle-like teeth to inject it.

    I can't imagine any of them serving a function alone.

    Perhaps the rattles started appearing, and snakes started shaking them. Or perhaps they started using a shaking tail to distract predators and prey, and then those wierd mutant rattles came in handy.

    We still see genetic mutations, and should one of them prove more useful... (read more)

    The poisons are variations on digestive enzymes, only turned up to 11 potency-wise.  Lots of enzyme producing organs have bladders to store their output until needed, so that likely would have copy-pasted in at the same time, and there are several species of reptiles which are venomous, but don't have fangs.  There seems to be a progression of teeth near the venom entry point becoming longer and grooved, eventually culminating in fangs. Digestion first, then pre-digestive saliva (your saliva has digestive enzymes too for that matter) then more potent saliva, then teeth to stuff it into the prey more effectively once it was strong enough to help with incapacitation and not just chewing, then more specialized saliva, then more specialized teeth.  Pretty easy to see how it would have developed a piece at a time.

    "This leads me to assume that each organelle in every living cell had to have an intelligent designer."

    but each organ within an organism didn't? What's the difference?

    Gotta love that watchmaker analogy. Turns out the human circadian (sleep-wake) rhythm is a little bit over 24 hours long - more like 24:11, so your body is always pushing you to go to sleep 11 minutes later every day. (Thankfully it tends to synchronize with light and darkness, so it doesn't get too far off schedule.) That's some nice watchmaking there, God.

    6snowfarthing13y
    Is that 24:11 a literal figure for every single person, or is it just an average, over a a group of individuals? Since the day/night cycles vary all around the planet, it would make far more sense, from a design standpoint, to worry more about the synchronization mechanism, than to get the exact sleep-wake rhythm correct.
    1TitaniumDragon9y
    It isn't literally that for every single person, but assuming you don't have a mutation in your chronobiological genes it is pretty close to that. People with mutations in various regulatory genes end up with significantly different sleep-wake cycles. The reason that our bodies reset ourselves under sunlight is probably to help correct for our clocks being "off" by a bit; indeed, it is probably very difficult to hit exactly 24 hours via evolution. But 24:11 plus correction lets it be off by a bit without causing a problem. Good enough is probably better than perfect in this case, both because it means that mutations to the clock are less deleterious (thus those who have mutated clock genes are more likely to survive if they have said adjustment capability, meaning that the adjustment gene is even more strongly selected for) and because it means that we can travel and adjust to new time zones. For most creatures, this doesn't matter, but for creatures which travel long distances, this is a real advantage for staying on the proper day/night cycle.

    Eliezer...

    It really bothers you that a mindless, unthinking process is smarter than you, doesn't it.

    I wouldn't go that far! But I do think you bias towards Faith in Flawlessness and against anything that involves randomness.

    Foxes seem well-designed to catch rabbits. Rabbits seem well-designed to evade foxes... When I design a toaster oven, I don't design one part that tries to get electricity to the coils and a second part that tries to prevent electricity from getting to the coils.

    Toasters are designed for simpler problems. When you need to survive overwhelming complexity/unknown unknowns/fog of war, designs relying on Feedback/Checks and Balances often survive where designs without it fail spectacularly. Examples: US founding father's design for a government; various engineering control systems; successful economic systems; protocol about feedback in science.

    Human beings fake their justifications, figure out what they want using one method, and then justify it using another method.

    Hmm...

    When I design a toaster oven, I don't design one part that tries to get electricity to the coils and a second part that tries to prevent electricity from getting to the coils.

    Er, yes you do. There is a latch to hold the contact closed, there is a thermostatic switch to dislodge the latch. It is such with many designed control mechanisms.

    If you look at the ecosystem as a designed work of art rather than a designed mechanism to accomplish a purpose, rabbits and foxes competing isn't so much of a problem. Still, it's not very plausible; while there is beauty (as humans see beauty) in nature, as a whole there's not much of a consistent aesthetic.

    Selfreferencing, I'm a Bayesian. I assign probabilities, not "believe". I penalize hypotheses by their unshared complexity and update based on evidence. If probabilities come out even, then I don't "suspend judgment", I judge that the probabilities are even, and plan accordingly. It's just as much a belief as anything else, and just as mandatory or prohibited based on a given body of evidence.

    Celeriac: Sigh. Gating the flow of electricity and the function of the toaster, is not the same as having two parts at flow with each other. When I open the latch, the power circuits don't try to reroute electricity to the coils, or fuse the latch...

    Recovering: Don't know where you're getting the "faith in flawlessness" part. Did you read the part about the retina?

    Eliezer_Yudkowsky: Did you see the recent "What's the most important[or whatever] idea?" thing on edge.org? Richard_Dawkins's answer was Darwin's theory of natural selection, and he justified that on the grounds that the metric for a good theory is:

    "what it explains, over what it needs to explain"

    and then pointed out how it "explains" billions of species.

    Now, he may just be using different labels for the same point you made in your post, even so, that's a remarkably confusing way of describing the appropriate way to judge a theory. That would suggest that you can't blame popular confusion on errant usenet Darwinists, that the confusion comes from the most credible biologists.

    0TitaniumDragon9y
    The idea of natural selection is remarkably awesome and has applications even outside of biology, which is part of what makes it such a great idea.

    To actually explain an outcome, you must only be able to make-up-a-plausible-sounding-explanation-for that outcome, and not make-up-a-plausible-sounding-explanation-for zillions of other possible outcomes. Evolution does this, successfully, for millions of species, which is good.

    The more actual outcomes a scientific theory explains, the better; the more potential outcomes it could have explained just as plausibly, the worse.

    Sorry if this wasn't clear.

    Shameless nitpick: There's nothing wrong with the logic that "radiation causes mutations, so more powerful radiation causes more powerful mutations." If you expose yourself to a thousand rads, you will get a heck of a lot of mutations. The logic breaks down when you expect these mutations to give you super powers, rather than a big mess. It sounds like you've got the superhero logic backwards: people did not look at evolutionary theory, understand it incorrectly, and then hypothesize that superheroes should be an expected outcome. They first made up the superheroes, and then looked for anything which might plausibly explain them.

    Eliezer, I grasp the obvious utility of probability -- I pay for a variety of insurance policies, after all. But there are many claims (many of which you share with us on a daily basis) that you treat as having a probability of 1. About those claims, I find your assertion that you do not "believe" them to be a purely verbal distinction.

    Well, in a lot of senses I treat them as having a probability of ~1. But not literally 1, because when you assign a probability of 1 to something, you can't change your mind about it, ever.

    There's also the whole distinction of viewing "belief" as a primitive, rather than viewing it as a derived behavior of a system that happens to be assigning probabilities close to 1.

    But then my brain doesn't actually work by Bayesian probabilities, so, yes, I believe gravity, and that if I don't eat I'll die of starvation, and many similar things whose opposites I don't bother to consider.

    tggp-1) google--tuberculosis strain w evolution of 2) down the page go to the amazon book review of "Quantum Evolution" by Johnjoe Mcfadden. This will call up a page that includes the most relevent info. I realize that the info on this is not well advertised. Of course when a theory that is promoted for so long as the explanation of everything (See Dennett's "Darwin's Dangerous Idea") predicts a cure and produces an incureable disease with an ever increasing pile of dead bodies-- This is a real life example of the problem and dangers of bias.

    I was nodding in agreement up until the end there. "Evolution is bodiless"? "Evolution" describes certain features of a physical process, a chemical process specifically, stretching from the beginning of life until the present day. The entire ecosystem of the Earth is, at any given moment, a time slice of this single chemical process. It isn't abstract in the least. Various sorts of selection are abstract but only in the sense that they describe aspects of this chemical process at a high level.

    Well, bodiless does not necessarily mean abstract, here it's more about omnipresence and lacking defined boundaries. You can't run a stake through evolution's heart or poke out its eye as every cell uses it.

    Douglas, you've said more than once now that evolutionary biology, when applied to tuberculosis, "predicts a cure and produces an incurable disease". Maybe I'm being dim, but this seems to me to be absolute rubbish.

    1. Antibiotics did and do cure a whole lot of TB, and have saved an enormous number of lives by doing so.

    2. Evolutionary biology, so far as I know, didn't have anything to do with the development of antibiotics as TB treatments nor with the way in which they were used.

    3. So far as I'm aware, orthodox evolutionary biology doesn't make any

    Great stuff, Eliezer. I'm really looking forward to you compiling your writings in a book.

    douglas, I googled tuberculosis strain w evolution of and it didn't give me the result you were thinking of for quite a number of pages, so then I just searched amazon for "Quantum Evolution", which revealed a number of titles other than the one by Johnjoe McFadden. There still wasn't that much information there, so please give a web address (you did not in fact give me one before, I should be able to click on it or copy-paste it into the url bar of my browser). To me right now "quantum" is just serving as a magic word, I'd like a (likely simplified) explanation as to how quantum mechanics patches a hole in evolutionary theory and what that hole is in the first place.

    "In microbiology, genetics, cell biology and molecular biology, competence is the ability of a cell to take up extracellular ("naked") DNA from its environment."

    I don't see what problem this causes for evolution.

    Douglas:

    1. You have not explained how anything to do with tuberculosis poses any difficulties for orthodox evolutionary biology. Gesticulating vaguely at a book that, on the face of it, looks mildly crankish is not an explanation. Repeatedly saying "Google for tuberculosis strain w" is not an explanation. I may quite possibly be being dim, but you aren't showing any sign of actual willingness to help correct my dimness.

    Well, I'd rather name it after Galileo, but otherwise I'm happy with that. Galileo invented the field of endeavour that we know today as ‘physics’ (a term which Aristoteles used for something rather different), and Newton brought his ideas to fruition, even though they have subsequently been improved upon. ‘Newtonian physics’ is one thing, but ‘Newtonism’ is another; all modern physicists are Galileo's and Newton's disciples.

    Snow in a tv screen is not random, but in fact a fractal image made up of multiple intruding signals, the strongest ones having the most to do with the seemingly random image. So that seems a lot like evolution to me.

    Fell free to correct me if I'm wrong, just throwing out my two cents.

    The evolutionary process is poorly characterised as being blind or idiotic:

    Human beings are the product of choices by intelligent agents, capable of predicting the consquences of their actions, and are not - in any reasonable sense - solely the product of "blind" selective forces.

    Taken into effect that the "blind watchmaker" has been working on every organism on earth for billions of years, the complexity and diversity of the same environment, it is no surprise that humans would want to take the quick and easy path. The outcome will probably be disastrous which is kind of amusing.

    So basically you're saying that evolution follows the idea of "a million chimps in a room will eventually write Shakespeare"?

    You'd think this would be uncontroversial, but I often have great difficulty explaining what it means for evolution to not have a purpose. "But if it's just random, then how does it work?"

    "The main point is that the gene's effect must cause copies of that gene to become more frequent in the next generation. " Pah! I disagree. The gene's effect must not cause copies of that gene to become less frequent in the next generation is the very best you can hope for. More accurate still is that in conflict and cooperation with other genes in the organism the genes effect must not afford less of a chance of being given a free ride.

    Isn't the vast majority of DNA just genes that don't do any harm? Evolution is not the thrusting, carving, shaping force depicted so often, it is (as usual) the work of a small (say 20% (a guess)) of genes and the rest just don't compete so get a free ride.

    I'm not sure you can assume that Odin isn't around. He was relatively hands off in the legends, so no evidence for him is not proof that he doesn't exist. It could be a fitting end to a life struggling against blindly cruel Nature where upon death, you go to Valhalla if you die in battle; otherwise you go to hell.

    0gwern14y
    Odin messed around with humans all the time; certainly his offspring did. Leaving aside Siegfried the dragonslayer (and the whole Volsung cycle) and Odin's general interference in wars, he is depicted as wandering the human world checking up on humans (usually rulers), as in the Grímnismál where he executes a king for violating hospitality. (Arguments about Norse myth are hard to do in general, though, as there isn't very much to go on.)
    -2jafl14y
    Fair enough. I only picked Odin since the article mentioned him. My point was that lack of evidence doesn't prove non-existence. It's certainly true that there is plenty of evidence against a God who constantly meddles and makes everybody's life perfect, but there is no evidence for or against a hands-off God, e.g., http://www.fullmoon.nu/articles/art.php?id=tal -- admittedly pretty much by definition :) For that matter, there are enough crackpots among us that a weak signal will be lost in the noise. That applies equally well to acts of God and the existence of UFOs. To be clear, my only claim is that we don't actually know for sure one way or the other, regardless of how many claims for their existence have been disproved. Enough dearly held beliefs about the physical world have been overturned in the past century, e.g., Einstein on quantum physics, that we shouldn't assume we know everything now, either.

    New user, folks. Be nice with the karma Hey, welcome to Less Wrong. Introduce yourself here if you like. In the same way you might say that there is no evidence against a silent and invisible dragon in my driveway. But none of us believe in invisible dragons in our driveways because they're so unlikely we would require a lot of evidence to convince us they are there. The same goes for God. God, as it is usually described, is such an extraordinarily complex entity that the chances of one happening to exist are so small as to be irrelevant until we have a lot more evidence in favor of it's (His) existence. See this and the articles listed as prequels at the top of it for deeper discussion.

    "I'm not sure you can assume that Odin isn't around." It's an inference, not an assumption. "no evidence for him is not proof that he doesn't exist" Who said anything about proof? We should teach epistemology in kindergarten.

    The human retina is constructed backward: The light-sensitive cells are at the back, and the nerves emerge from the front and go back through the retina into the brain. Hence the blind spot. To a human engineer, this looks simply stupid - and other organisms have independently evolved retinas the right way around. Why not redesign the retina?

    Some of the biggest jaw dropping comments I hear have to do with taking something that is an obvious flaw and bending over backwards to come up with a reason that it isn't flawed. Instead of saying that old elephants starving is cruel and a flaw* they say that there is a deeper purpose or design that can explain away the cruelty.

    Instead of calling out a nasty thing for being a nasty thing they try to claim that our understanding is flawed. and the nasty really isn't all that nasty. This is fuzzy enough on topics like retinas and dying elephants to trick people who don't know much about retinas or dying elephants.

    I wouldn't get so worked up about it. The point of these demos is not to claim that evolution explains mousetraps - it doesn't - but to undermine the irreducible complexity argument. It's quite capable of accomplishing that. Almost anything could have a plausible evolutionary route in the presence of an arbitrary selecting force. But evolution by natural selection does not provide arbitrary selecting forces. Natural selection doesn't build better mousetraps and clocks and such because those aren't capable of providing the machinery (i.e. being alive) that makes natural selection work.
    4JoshuaZ12y
    I agree almost completely. Just note that being alive isn't the relevant criterion for natural selection. It is being an imperfect replicator. An imperfectly replicating machine could just as well be subject to natural selection. This brings up issues of what we mean as alive but I think that most people would not consider for example computer viruses as alive, but in the very long run they should be subject to natural selection.

    Your brother or sister shares half your genes.

    This is rarely true, you share 50% of your genes with your mother an father each, but you can theoretically share anything from 0%-100% (Probably normal distribution curve), since your mother/father has 46 (23 pairs) chromosomes and you receive a single random chromosome from each pair (total 23 singles), that are then paired with 23 singles from your father/mother.

    Note that I have not taken Chromosomal crossover into account.

    For a given rare genetic difference from the population at large, you have roughly 50% chance of sharing it with your sibling, a child of yours, or a given parent of yours. Absent some sort of green-beard effect, the effect of selection on each will be approximately the same and thus (getting poetic) similarly guide the hand of the Alien God.

    Yes I agree and that was not something I was disputing. From one gene's point of view there is a 50-50 probability that your sibling carries that exact same gene.

To a human engineer, this looks simply stupid—and other organisms have independently evolved retinas the right way around.

    This isn't entirely accurate - there are advantages to having the retina at the back, because the nerve improves visual precision. I don't recall exactly how this works, but I read about it in Life Ascending by Nick Lane if anyone wants to verify it.

    2chkno11y
    Life Ascending claims that the neurons out in front may act as a "'waveguide'" to funnel photons more efficiently to the light-sensitive bits. This topic is treated in much more depth in Live Cells as Optical Fibers in the Vertebrate Retina, which I read as marveling at how the darn thing works at all.
    1Kawoomba11y
    There are advantages to dying at age 30, too. The Achilles' heel of such thinking is that you can find arguments for or against anything. Despite some workarounds that got selected for to make the "darn thing work at all", the general failure mode is quite evident from a phylogenetic trace, from an engineering standpoint and from the way that evolution on average only selects for neutral or greedily beneficial mutations. After a certain point there was just no stochastical way for the retina to invert itself back to "sane architecture", it would have necessitated too many mutations at the same time. Same time, because otherwise the intermediate steps would be at a clear disadvantage and thus would not propagate. chkno linked an excellent paper in the other response.

    TLDR: We describe evolution as the collective pressures that cause creation of new species, similar to gravity and water carving out various canyons. It is incorrect to react to canyons in the following way: "Canyons are they way they are for no reason?! ha! I know that they are the way they are because the goddess Erosia likes them in that shape."

    So basically the bottom line I'm getting from this a kind of variant of Occam's Razor: Evolution is unlikely to produce solutions that include complexity or considerations it doesn't need.

    Or more specifically, and with an example, there are probably a lot more ways to get to taste buds that give good results in environments and contexts the organism is likely to encounter than ways to get to taste buds that give good results in both environments and contexts that the organism is likely and unlikely to encounter.

    To strongman a counter to the fox-rabbit-toaster argument: when you make a toaster, you do make a part to prevent electricity from getting to the coils. In fact, you make several of them. First, you make a timer to shut the toaster off when it's done. You also make a fuse, an some over-heating shut-off switch. These prevent a run-away situation that would cause the toaster to burn down your house. So an advocate of a god who makes both rabbits and foxes could point out that foxes and rabbits make a self-regulating population control system, and that would follow the same sort of engineering logic as putting a fuse on a toaster.

God created evidence to prove that the universe, earth, and life came into existence and developed slowly by natural processes, without any apparent divine intervention. He left this evidence everywhere for us to discover — in the rocks, in fossils, in the DNA of all living things, and in outer space. Since God chose to hide his divine creative powers by using only natural processes that make him redundant, we can conclude he wants to remain invisible and not be acknowledged or worshipped. What do you think about it?

    "What do you think about it?" It's wrong.

    “Whatever happens, happens because of the genes themselves.”

    I agree, but isn't there much more to it than that?

    In other words, the behavior of genes themselves will dominate, until and unless a meteor crashes into the planet, thereby introducing massive evolutionary chaos and entropy due to a cocktail of forces that destroy some species while placing immense evolutionary pressure on all. This would be accompanied by immense radiation that acts as both an accelerant and randomizer that injects both leapfrogging and gaps in otherwise linear genetic evolution... (read more)
