    I honestly don't think that we are really going to evolve much in the future. Since our population size is so large and people from all around the world are connected I just think that we will become more and more similar to each other due to gene flow between previously isolated populations, resulting in a loss in geographical variation. This will not shift our phenotypic mean, but it will result in a decrease in variation between individuals. natural selection and genetic drift will still result in changes in allelic frquencies, however these will be diluted in the large gene pool so that even successful alleles will not be able to reach fixation, this will prevent changes from accumulating over successive generations. We will enter evolutionary stasis and only "wobble" about our phenotypic mean without changing much over
    a long period of time. I think only the iscolation of small populations (somehow) or a catastrophic event that reduces population size and destroys our interconnected civilisation will be the only way we can evolve further.

    The shrinking brain for efficiency idea actually makes a lot of sense in the genus homo
    Humans have one physical advantage over other animals: extreme endurance
    Bipedalism gives us an extremely efficient gate, meaning that although our prey can run faster, we can run further
    Currently 20% of the bodies energy is used by the brain, yet it only makes up 2% of its total mass, so a more efficient, yet equally as capable brain should be a welcome addition.

    So who is more evolved? Is there a race that is more evolved than on other? Who will break out and become the next evolutionary super being and what will that being be called? Will dogs pass us? Will we evolve far enough to create intelligent life? Will that life form reject us as creators and accept evolution as fact

    How would domesticating cattle turn on the gene for digesting dairy? Do we just assume this to be a coincidence? If so, it seems like a big one -- and an extremely lucky coincident at that.

    • renge9909
      renge9909 Month ago

      I believe it's more that there is a disposition for a mutation of that gene which controls dairy tolerance. For a long time, there was no big deal whether the gene was on OR off, because it had no effect on survival. Both types of people were weaned off breast milk, carried on with their lives, and reproduced at roughly the same rate, thus carrying on both on and off genes. With the domestication of cattle, and thus a more steady source of nutrition dense milk, the ON gene became more and more favored because more ONs were surviving to reproduce.

    I thought that there was a type of bacteria that allows us to digest milk. I've read that if lactose intolerant people drink small amounts of milk over time the bacteria will populate their gut and they will become lactose tolerant. I didn't think it was about a gene being turned "on" or "off"

    Lol, *idiots everywhere in the comment section* sorry.. never been a sucker for comedic excuses and lying to oneself..

    Humanity is just against the truth, that's all, people saying we evolve.. or just generally getting better in any sense is lying to themselves.. we have never had as many diseases as we have now, or inequality in food supply.. or diverse and confusing sexual orientation.. even though it feels like ya won't experience any of the diseases and suffering because ya are delluded to think we have it better now than back then just because of some advances? And that evolution says we shed our fur to protect us against parasites or whatever? We have so many deadly diseases now, Ebola and aids is an "least" concern.. the next thing in our evolution would probably be complete baldness, no follicles and I don't know if that have any significant change.. but it's definitely a minus for us.. most of us woulds freeze in a few higher degrees and so on.. and girls would look weird as fuck.. we'll have baldness activists first lawl.. not even kidding.. humanity becomes more of a joke by the decade.. it's going fast now..

  • Maria Prado

    I think about this video all the time and It makes me super worried. I really dislike the idea that humans biologically speaking are likely to become dumber with evolution. I mean I get the brain size isn't 100% perfect in correlation with what we consider "intelligence" (it's is kind of an arbitrary concept) for example dolphins have a larger brain than humans and we generally consider humans to be smarter than dolphins. But still the idea that humans are as a species going to be come less "smart" over time and less fit to survive in nature as individuals makes me extremely uncomfortable and honestly a little pessimistic. In conclusion I like this video and find it very informational but also I hate it a lot and it gives me anxiety.

  • Afrodisiac
    Afrodisiac 6 months ago

    Bio major here. Usually I'm fine with the facts that you present in your videos, but the part about the shrinking brain can be misleading. For one a bigger brain doesn't equal a smarter brain, even in proportion to body size. If that was the case then men would be smarter than women, something that might be funny during a standup routine, but complete nonsense in terms of science. Human brains are getting smaller because their getting more efficient and using up less energy (like you implied); however this discrepancy in brain size really doesn't affect intelligence in a major way that we can conclusively see. Our ancestors were just as smart, but ultimately used up more energy to do so. Becoming dumber over time would have been stupid since humans had to survive in the wilderness for hundreds of thousands of years. No way in the last 10,000 years has natural selection favoured stupider people, but when more humans compete for more resources saving energy becomes very important. Hence, the energy guzzling brain needs to be made more efficient to reduce its energy consumption. I don't have the citations on me now, but I also read a paper a few months ago regarding brain size in hominids which stated that Denisovans and Neanderthals both had larger brain mass than modern humans. However, the overall trend for the shrinking brain seems to be asymptotic i.e it's eventually going to plateau at an equilibrium where our physical brain has reached max efficiency.

The earth is about 4.5 billion years old and Im told evolution takes 1 million years, that would mean it took about 4500 years to get were we are today. In that time frame no other species can rival our possibilities ? Also what bc stands for again? its used in science teams I think.

  • István Sipos

    I tried and tried but I simply could not find any useful material on this, so I ask you:
    Why are skin- hair- and eye colour, facial and body features, hair type and many other things so diverse by caucasians, and less or much less diverse by all the other races? I don't say that all the Far Eastern people look alike, but they f.e. have the same hair colour, and they never have blue, gray or green eyes. What is the evolutionary benefit of this similarity (if any) or what is the reason for it? I am just asking, because the Far East is huge, with all kinds of different climates. If we compare the northern part of Japan to the southern part of Vietnam f.e, we find totally different weather and climate, yet people in these regions are far less different from each other than a Norvegian dude is different from a Spanish dude, f.e

College is set up by the same people who worship higher powers behind locked doors, they tricked you in to it with the basic promise of money. they don't want you to believe in God and they want you to focus on money, think about it for a second. For the love of money be the root of all evil, WORDS FROM THE BIBLE, THAT THEY SWEAR IN ON.... evolution is such a dumb thought that you have to believe in just like the concept of God to an evolutionist you have to belive in it. PROVE ME WRONG!!!

    Why is it that so often in the context of human evolution larger brains are almost always assumed to = higher intelligence, but in pretty much any other context scientific consensus remembers that this assumption had been disproven a long time ago? People who have bigger brains aren't necessarily any more or less smarter than people with smaller brains - we've known this for over a hundred years or so by this point. Animals that are smaller tend to have smaller brains, but this doesn't have much to do with relative intelligence - for instance, corvids are on par with primates in terms of intelligence, regardless of brain size. And yet in conversations about the evolution of human intelligence, it seems the size of the brain is always just assumed to be an indicator of intelligence. I can understand if there just isn't a whole lot to go on besides corpses and stone tools, but frankly I think this brain size thing just isn't what it's often made out to be.
