    Great video! One critique: I think a substantial number of biologist would disagree with referring to DNA that doesn't code for protein as "non-functional". That DNA impacts the cell whether it is the energy used for the frequent replication and transcription that DNA, or the interaction that DNA (and it's RNA) has with other molecules in the cell, or cis-regulatory elements within that DNA etc. The function of that DNA is typically more robust to point mutations, but that doesn't make that DNA non-functional

    I think accepting the assumption that a majority of DNA "has no function" is a fraught position to take. We thought a lot *more* of it was "junk" just a few years ago. There's a certain amount of hubris in the ideas here. as they make the almost manifestly wrong assumption that we now do understand what *all* DNA does, whereas we have a history of just ignoring the parts we don't understand now.

      Ditto. But the point is not that it has no function but that it is variability that doesn't significantly alters fitness, that's what "neutral" means. Like people having slightly bigger or slightly smaller noses, slightly thicker or thinner eyebrows, etc. (mind you that skin color is not neutral, it was driven by dramatic selective pressures: solar protection first, vitamin D urgency later).

    Darwin lived in an era in which natural theology was still popularly used to explain the existence of biological function (that is, god created organisms to live in certain ways), and introducing the idea that function could be created and maintained naturally (by natural selection) was revolutionary. But more than a century later we find the possibility of natural selection obvious and intuitive, so now we are free to investigate all of the traits of organisms that are non-functional, or at least non-optimal. Darwin himself discussed this in terms of sexual selection, of course.
    A similar debate happened in the history of geology. Initially geologists believed that Earth was largely shaped by catastrophic events, including the biblical flood. In response, other geologists argued that given enough time even gradual, uniform forces could change the face of the planet, and we don't need to use religious myths to explain things. Now we understand that the Earth does change slowly over long periods, but it also suffers periodic catastrophes, like erupting volcanoes, ice ages, and asteroid impacts.

      ​@@The0ldg0atI think that it's partly an issue with the fluidity of semantic meaning. Something being fit for purpose just means it's features don't cause unnecessary frictions when applied to a specific purpose. When that purpose is survival, then it should just mean those with features that better help them survive, will survive. The catchphrase is not wrong but the question of what fitness looks like depends entirely on the situation. On its own It's an empty phrase that people read with a colloquial understanding and missed the entire point of the statement.

His theories regarding naturalism bled into creating a world understood solely by nature and nature alone exempt from the influence of God. So "survival of the fittest" was his mantra which driven partly by Darwins book "On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life".

      An environment is not defined plainly as the physical space organisms inhabit, but as the conglomerate of space and resources relevant to the organism you're studying. Bacteria and mammals might share a physical space, but their environments are differently defined cause you would highlight the relevant aspects of it for each group to define their environments. And because organisms change those relevant aspects to fit them better, there's no environment without organisms.

    Drift is very real but only shuffling in the end. If your people randomly gets a bad hand, it will still lose in the end.

    2:07 - Your illustrative experiment does not include mutations. Without them we would have homogeneous populations and no evolution at all. The only prerequisite for a mutation not to be eliminated by selection is that it is not overly detrimental.
    Geneticists and other biologists would be well advised to use more mathematics and less hand-waving. Then there would be no "debates" about gene selection vs. kin selection vs. species selection etc. Mechanisms are the same, simple and few. The rest are just emergent effects stemming from statistics.
    With all due (umm, due?) respect for all these quarreling evolutionary biologists, all what you said in this video is a no brainer, and subject to pretty elementary mathematical analysis. People, evolution is not a religion with different sects, but scientific discipline which should employ quantitative methods.

    While random mutation can influence evolution, it's important to note that natural selection is still by far the most important factor. Mutations that may seem neutral may actually have very slight positive or negative effects on a species. Over a long enough period of time, mutations that have slight negative effects would be weeded out and vice versa for positive traits. You can see this in traits such as not having wisdom teeth, this has only a slight benefit but is still naturally selected on.

      If only there were a way to prove that baseless assertion. Two hundred years of the theory and there isn’t one because that would mean having access to information that is simple not available. Of course environment exerts an evolutionary pressure. But it’s not a sufficient explanation for most things in complex organisms because there’s so much that’s simply superfluous to a given environment so it isn’t the environment that’s determinative. A “better” adapted species can go extinct while a nearly useless organism survives, even over millions of years. All of your so-called explanations are “just-so” post hoc reasoning and it’s very unconvincing.

    • @gatuarhin

      @sgttomas Species only go extinct when their environment changes faster than the species can adapt. For example, if a new species comes to compete for the same resources. There are no "better" species that go extinct randomly, and there are no "useless" species that simply survive. Keep in mind that most beneficial mutations only give a slight advantage to an individual. If luck leading to individual outcomes was stronger than this, then evolution wouldn't exist.

      Natural selection is when the organisms carrying a mutation
      a) can reproduce sufficiently more that those without, and eventually supplant them (adapting to evolutionary niche) or
      B) are the only ones capable of living to reproductive age after a major change in the environment or
      c) after a major extinction, there seem to have been explosions of diversity among a category of organism, presumably because the environment temporarily increases the rate of mutation and/or allow for easier survival of mutations in a depopulated and less competitive period.
      As per the video, mutations happen all the time, at a fairly predictable rate, and most either don't allow the mutated organism to live to reproductive age, or they don't influence the organism's chances of survival either way.
      My Dad had three kidneys and one testicle.
      Those mutations didn't prevent him from reproducing, but neither I nor my sisters inherited either mutation.
      TLDR: Without mutations, no species could adapt to better suit its environment, there'd be nothing for natural selection to select for.

    Amazing video. The niche construction thought is simply beautiful. It is probably very common thing to occur. We as humans took this to another level by adapting our environment to us (spanning from building cities to occupying space on the ISS).
    An interesting example came to my mind. It has been shown, that as we are using our smartphones, the number of connections between out thumb and the brain is increasing. Moreover, in some cases, the thigh is more responsive to touch (vibrations) as we carry our phones in a pocket. This isn't really a matter of evolution though. It simply isn't that fast. It's more like an adaptation of our nervous system to a new part of the enviroment. But we made this environment possible in the first place...

    As an example: The Chin (by raw chance) is sexually dimorphic, and is, as a result, small chins are strongly selected against in men, but not in women.

All it’s really doing is describing the fact that if something doesn’t replicate genes over the course of long time spans than that thing ceases to exist. So by definition, all things that exist are good enough at existing that they still exist. And if they aren’t good enough the go away (or get selected against by NS if you want to put it that way).

Hitting the chin with your larger knuckles is the safest spot to hit for a clean punch to the head and hitting the head is the only effective way of incapacitating someone when weapons and grappling is not an option. Wrestling/grappling is way more important than boxing though and what fights reduce to if unarmed and not as rulebound. Wrestling is much more common as a sport for competition and play in the past and present since injury is much less likely. And elbows, feet, knees, and forehead are good for striking as well.

    When you consider the hundreds of millions of years that can span between species, it’s easy to imagine that any specific trait may be a snapshot during a process that takes eons. Consider an animated drawing. Different key frames define the overall movement, but inbetween frames may or may not be intelligible, but they are necessary to get from one key frame to the other over time. Now imagine it takes millions of years to get form one key frame to the other instead of 24 frames. You’re not going to be able to tell if that weird squishing motion or that motion blur is a defined or useful state, but it’s a process. Mutations are random by definition. Who’s to say a mutation is useful or not ? If it doesn’t hurt the species in any way, it’s just propagated until it disappears naturally over eons. Language go through the same changes over time. Their particularities may or may not be useful to communicate anything, but we gain or lose spelling, grammar or even whole words by usage, code transfer, assimilation, erosion or obsolescence.
    Whatever the species’ trait looks like now may or may not be useful, but it’s just a snapshot from an extremely slow motion movie.

    Great video! One minor complaint is that chins are an odd example to use, given that people with weak chins are typically far less attractive than other people. I don’t know how universal that viewpoint is, so I don’t know if attractiveness is a plausible explanation for modern chins, but most of your audience probably do view chins as more attractive than lacking them (even though super strong chins are far more polarizing), and may decide natural selection to be a more favorable interpretation of that particular trait than random chance.
    Also, quick question, isn’t it possible for new genes to occasionally arise out of non-coding DNA. Obviously not often given the low probabilities involved, and even more rarely positive, but isn’t it a possibility, or does something prevent noncoding DNA from ever being recognized as coding DNA again, and new genes have to always arise from duplicates of existing ones?

    there is a dynamic hidden in the gene and physical interaction of chemicals and cell behavior, against an environment, evolution is not as random as it may seem, families of species could be sharing a common evolution program that guides them through a subset of possibilities way faster and directed than we can prove right now. This program is life itself and it's extremely expensive to model accurately. Life is not only species and specimens, it's also a system that generates them, this is what we don't understand clearly, we can only point at some small aspects participating in the system. The high level understanding isn't there yet. Take nutrition for instance, we don't even have a clear picture of all the gut bacteria species and how they interact and help or work against us. We can't heal someone that has the wrong ones, it's still a science in its infancy, but it's critical to health and it's the most important aspect of any animal life. We can't read someone's epi-genetics, we can't read someone's immune system state (all memory gathered, all cells activation state, all produced antibody) we can't fix hormonal issues at the root (only compensate with huge side effects), mental health is still hard to improve. We seem to improve our way of life but disease rate skyrockets All of this is about only one species and we don't have a clue or we need all the science strength to diagnose one individual as a study only partially at huge costs. We're sill far from fully simulating an animal lineage to prove any theory. I suspect that individuals control their descendant evolution in a limited way but in a directed way, only a few generation exposed to big changes will evolve drastically. Then there is a superseding system in which descendant must belong, this system belongs to the species family, this system evolves slower and you do not need to evolve it a lot to produce seemingly completely different species. For instance cats, apes, dogs, horses have many variants but they share most of this framework within their group, what we need to learn is how signals go to living experience to evolution, what are the variable that are controlled when producing offspring. Could we live better lives by improving the evolution quality to our descendants ?

For example human's (and relatives) loss of ability to synthesize vitamin C, though its loss could also have been beneficial. Another is cats losing the ability to synthesize Taurine, which is only found in meat, which is all cats eat. These changes could severely harm the emergence of some herbivore cat or humans ability to travel the seas eating nothing but dried jerky and hardtack. Even if these examples turn out to be advantageous, it seems clear that genetic drift COULD destroy significant, but neutral genes, which hurt the long-term adaptability of a species.

      Genetic drift can destroy important genes that are currently beneficial if they're held by a small enough percentage of the population. It is pure randomness, even if your population has better odds of surviving that doesn't guarantee anything.
      Another part of the neutral theory which wasn't touched on in this video is that not only are beneficial mutations rare, they're made even rarer by the fact that genetic drift destroys a significant amount of them. Within the first few generations of a gene's existence it is very vulnerable to simply having the entire population carrying that gene be wiped out completely. It doesn't matter how beneficial the gene is, there's always a chance that every member of the species with that gene is killed by a predator when we're talking about a gene that less than ten individuals may have.

    I'd think that when a mutation for a new trait occurs though, the large the current population the less likely it would be to spread... but, that said, in a larger population you'd have more random mutations occuring, so the overall chance of one of them spreading would remain fairly high. So, if the gene for chins appeared in humans (or one of our ancestors) it's chance of going from one individual to dominant would largely depend on it being a survival trait, or at the very least that individual having a good set of other genes.
    If it's spandrels, then I'd argue that the chin is not the adaptation... the smaller jaw do to smaller teeth would be the adaptation. The chin would just be an artifact of that adaptation.
    In addition to deleterious, neutral, and advantageous mutations I'd think a lot of mutations are situational. A mutation that makes you taller is great for a creature that eats leaves off of trees, but maybe not so good for a creature that lives tight caves.

    Simply regarding the title and thumbnail text, it’s important to understand that at the end of the day what natural selection is really doing is weeding out reproductively non-viable traits.
    It doesn’t matter if something is the best or most optimal for a given task. All that matters is that it works well enough to continue to exist.
    So if something randomly evolves and it works then it stays. If it doesn’t work then it goes away. In this way things that don’t negatively effect reproductive success can stick around.
    The point isn’t to believe that natural selection is choosing a bunch of things that work. It’s just eliminating what doesn’t. What we’re left with is traits that are beneficial and traits that don’t matter. Or traits that are harmful but still work enough to not go extinct.
    I don’t think natural selection is over hyped. I think people get confused when we personify it. But those nerds who actually study it don’t make the mistakes that lay people do.

    It's not random...but it's also not really selective.
    At the quantum level, still nothing is random...but it's "uncertain" There is a difference.
    But after that, everything is consequential. It's not deterministic, because the whole pile is quite expansive and dynamic, but it's not random because everything does follow linearly. It's just that there are more lines than you could ever possibly account for.
    What ends up happening is that any given factor...some chemical or compound, radiation, improper DNA recombination, any of a trillion different things...screws up a molecule somewhere. That causes the associated gene to express differently, or even not at all (and this is all without even touching epigenetics, which...holy fuck, is that a rabbit hole...). The biological consequences of that change of expression manifest in some way in the organism, and either it negatively impacts the creature in some way, or it doesn't (almost never is it actually advantageous).
    Over time, through similar events that additionally screw up various bits, that trait might correct itself, or become exacerbated by other circumstances, or the creature or its descendants might've just met an unrelated unlucky end, and that trait permanently died with it. At some point, it begins to impact other traits, and further changes happen, generation after generation. Eventually, either one or more given traits is impacted so thoroughly that they become functionally different from before, or a completely new trait has "finished" forming anew, or various otherwise unrelated traits combine in some odd new way. When it goes far enough, speciation happens and that's how we wind up with everything in the ecosystem.
    Nature or evolution doesn't have a goal, or a purpose. It's just common chemistry in particular conditions, with consequences related to the rules of chemistry. A molecule that can reproduce itself isn't going to "seek" to do so. Depending on the circumstances, it either will or it won't. If it does, then that matters. If it doesn't do so, then it doesn't matter. If it does, then there's a chance the follow-ups might do so as well. Or they might not. Life as we know it today, is just the unbroken chains of the precursor molecules that happened to kick off that streak.
    When life first began, it was just an assortment of unremarkable and mostly simple organic molecules floating in rich (super dirty, really) water. The conditions at the time were sufficient to cause various reactions, and certain molecules started to "eat" others they'd float next to as a result...attaching together to become larger and more complex (loosely speaking). Eventually, they'd become so large, that they'd break apart if they weren't stable enough. Some that got too big just became big, inert hunks...too big to be consumed, but unable to react and attach to anything anymore. Most of those that fractured would've lost the capacity to "consume" others because of their new structure, being consumed instead by those still proceeding. But some broke apart in ways that allowed them to continue on, but changed. Some of those developed chemistry that gave them a capacity to bond in new ways and become far, far larger than their predecessors. And it all kept growing until eventually structures similar to viruses formed, then those changed and eventually some amalgamated into prokaryotes, then eukaryotes, and on and on...
    'Til...here we are. No intent. No plan. Just blind stinking luck across a field of circumstance. Not random, but not "selected" either.

    What you determine as the main drive of genetic variation depends on what you are focusing on. If you are focusing on the morphological changes, those selfish genes, or every individual transcription error. All those meaningless transcription errors that do nothing positive for the organism pile up in the gene pool. Passing from generation to generation doing nothing. Might do nothing for a million or more years, but they are in those genes for all that time just sitting there doing nothing. Then another transcription error (in another gene or maybe even in the same codon) does a thing, and that junk portion of the earlier gene isn't so junk anymore. This is where natural selection first starts to do anything at all. But it is also where the transcription error first makes any effect at all as well.
    So what is of more important then? The process itself. Focusing on the natural selection side of things or the transcription errors misses the boat completely. It is the process itself that is has all the hidden gems waiting to be found. Selecting for morphological change is easy. We have done it with everything from bananas to dogs. Increasing transcription errors is pretty easy as well. We are pretty good at giving things cancer and using CRISPR. Understanding all of those moving parts and deliberately manipulating them is what is really important.

Gould was a bit of a contrarian, and liked to turn things on their head, but he was a committed Darwinist, and defended Darwin against all comers. His biggest argument was against slow and steady evolution. He proposed the idea of "punctuated equilibrium", that is, long periods of relatvie stasis, interspersed wth shorter periods of rapid evolution. Most famously he argued with Richard Dawkins on this point. Personally, I think Dawkins was more correct, but I also think Gould had a point. There could very well be relatively rapid episodes of evolution amongst the more stately propcess of evolution. I also think they more or less resolved their differences before Gould passed away in 2002. Nothing in nature is really all that cut and dried, but Darwinian evolution still rules the roost. Natural selection is a very powerful force, and is responsible for most of what we see in organisms today.

So while there _is_ an environment without organisms, the vast _majority_ of the environment truly is because of organisms, and the independent part keeps shrinking as us humans continue to push technology to it's limits. I mean, we've arguably been the first ones to finally crack open the lithosphere and extract stuff. That has probably not been done by a life form before.

    I cannot tell you how often I refer to this video when explaining the adaptionist assumption in fields like behavioral evolution and so on. That is may be just an assumption and we should probably treat it as such until proven otherwise.

    A while ago, I made my own extremely basic life simulator where each organism had a set of instructions it would follow, sort of like DNA. These instructions would randomly mutate upon reproduction. What I found was that the organisms would gradually accumulate hundreds of instructions, with most of them being completely useless except for a select few. I was originally kinda confused by this and came up with wild theories, but after watching this video, everything makes sense. There was no reason, it was just random chance.

      @@samuelthecamel did you make it possible for them to select for variability of mutation regions? the idea for this means that the organism can compartmentalize and only expose parts of the genome to mutation as opposed to all at once... though not sure how to get this to evolve naturally, but mutatability needs to be able to mutate.

    This has an interesting implication for machine learning. Natural selection was a basis for hope for genetic algorithms to create incredible effects as our computers become more and more powerful (quantum computing was especially promising for this). But if the evolution itself, far more powerful than any computer we can dream of creating, gets stuck in its way and never changes, because positive changes in the functional element of DNA by random chance are extremely rare, this dampen the enthusiasm for self-improving programs, who will improve themself by the process of replication and evolution.

    This is pretty interesting in the context of genetic evolution - individual genes compete to reproduce most effectively within a genome, but a common end result of that competition is complex multicellular life, due to the emergent patterns of those genes cooperating for increased fitness. A trait that is a spandrel in a macroscopic perspective can easily be the result of a gene or genes that's reliant on other genes with more overtly beneficial traits at that level, or even be the product of a gene that's successful at the genetic level and merely neutral to the organism as a whole.

    nature doesn't care if choice is optimal or accurately analysing environment
    it just cares to not promote really bad elements and better shortcuts to goal get promoted naturally with time less often replaced but still can be replaced by chance lol
