    One thing that is important...but seems absent from most Naledi presentations...
    Is how Naledi's brain... while much smaller....seems to be organized much the same as ours. Just smaller.

    • @dukeon
      @dukeon Рік тому

      Almost seems like it might be a case like that of Floresiensis, where the cranium and brain presumably shrunk once they had settled on an island (they probably retained the same brain organization as H. erectus, but the neurons and dura became physically smaller and more compact.
      That’s been known to happen in dinosaurs and birds, for example. But if naledi really did have a similar brain to sapiens, except 1/3 the volume… what caused it to shrink? Must it have been an offshoot of the sapiens line? Since it appears a bit earlier in the fossil record, is it possible that sapiens’ brains started out like naledi’s and then grew very large?
      I highly doubt the latter… actually I doubt a lot of aspects claimed for this species. Just a gut feeling, as they seem a mishmash of 300k year old and 3 million year old features. It reminds me of Piltdown Man all over again, except I don’t think paleoanthropologists in this day and age would fall for something like that. There are too many ways to date the bones.
      I have no clue how naledi came to exist as it doesn’t seem to have a very advantageous combination of traits to survive. Unless it was primarily a cave dweller and had grown smaller for that reason, but I’m not sure there is any non-island precedent for that.
      Bottom line, it’s quite a mystery and the brain similarity begs for answers. I hope they are obtaining full genomes from as many individuals as possible. That seems like the best way to get at the truth. About a lot of things.

  • @voidisyinyangvoidisyinyang885
    @voidisyinyangvoidisyinyang885 Рік тому +3

    So, if H. naledi lived 300,000 to 200,000 years ago that’s a remarkable discovery.
    It means that a species of human with some surprisingly primitive features - including a tiny skull and brain - survived into the relatively recent past. Conceivably, H. naledi might even have met early members of our species, H. sapiens. One could even speculate we had something to do with it going extinct.

He made a comment about going through every little bit of the area for dna but why didn't he show us a list of the dna charts.

    One thing that may have been overlooked with language in a cave system is that bats use clicking.. tribes in Africa today still apply this form of communication. Has this click language been tested as to how far it would travel and maybe even furthermore the scratches may be a form of length to waypoints in conjunction with clicking to gain a distance from a wall as in echolocation.

    What a great video! You seem rather open minded for scientists of today, which is so refreshing. I have contended for a long time that perhaps man did not JUST come out of Africa, or that humoids left Africa millions of years ago and progressed 'out of Africa'. With this comment, I want to comment on your video in detail:
    1) You stated that the geology was the same back in you South Africa 'dig', but I see that the openings are so small, even for small people, that it really makes little sense that the geology was the same back then as it is now. I would ask WHY would anyone go down into such depths when it would take so much effort and be so dangerous? Also, how could they do that with no light? That would mean that they would have to have a torch in their hand to get down in the depths. So, I would conclude that the geology WAS very different back then, and that getting in and out back 200,000-300,000 years ago was a lot easier. I would also question that if it was the same back then, then going to the bathroom would have been a big problem for them as well.
    2) You implied that the current scientific understanding today is that it is the brain that gives us emotions, such as remorse, grief, sadness, etc., and then showed us a baby gorilla showing grief over his mom. But I contend that the brain, and its size does not relate to emotions, including grief, sorrow, happiness, etc. I raised dogs while my kids were growing up, and I have first hand experience of them having all these feelings, and that they show them as well. In addition, I have watched many, many animal documentaries, and it it VERY clear that just about all of animals (at least mammals) experience sorrow and happiness and show it as well, even birds with pea sized brains. So, all of these emotions are NOT human only, and it does not take brain size or brain power to have these.
    3) One of the big holes in modern science today is that the obvious, and some empirical data is often ignored or downplayed, especially in astronomy. But this is, or should I say, was the case with human history also. So, your dissertation here was very refreshing, since you really seem to be questioning previous notions and are really trying to look at the empirical data, and then make a theory. I look and see what mankind looks like today, with basically three distinct races, and with the European 'race' being so very unique and obviously so different from all other humanity. And that the Asian race is so different from Africans as well. So, the theory that all of mankind came from Africa makes no sense at all. So, it was very enlightening to me to find out that there are some humanoid remains in Southeast Asia that are over 2 millions years old. While the very first humanoid my have come from Africa with its great climate and environment, humanity probably developed all over the world.

    I honestly wish that Dr. Hawks hadn't gone down the Naledi rabbit hole. I was a lot more interested in his work before he started working on Naledi. Just as Bernard Wood questions the genus of Habilis, due to the chimp-sized brain, I don't see any compelling evidence why it should be considered "Homo Naledi."

      Lee Berger has hinted that they have some DNA that was able to be samples. Research has already documented signature admixture into all Eurasian populations with Neanderthals (this would include North Africans). In addition, Denisovan admixture as been documented in all populations from Asia with up to 4-6% in some populations in the Philippines, Papua New Guinea, Australian Aboriginals. Native American populations also harbor both Neanderthal and Denisovan admixture. There is some suggestion of 2 Ghosts in Asia, that could reflect a divergence of Denisovans in that region. Given all this admixture among genus Homo members outside of sub-Saharan Africa (Sapiens, Neanderthals and Denisovans), would it not be a surprise if such admixture occurred in sub-Saharan Africa among populations there. At least 2 distinct members of genus Homo overlapped early Homo Sapiens in Southern Africa. 1 is Homo Rhodesiensis, and Homo Naledi. A large body of research has been noting "ghost admixture" into modern sub-Saharan African populations that is not either Neanderthal or Denisovan. So the only possible candidates or Homo Rhodesienses and Homo Naledi
      Chris Stringer in a recent article "The Paradigm Shift in Our Understanding of Human Evolution: an Interview With Chris Stringer" is on record saying that he views Neanderthals, Rhodesiensis and Erectus as all Human.

    Hold on a minute here. So these hominins were typically smaller than modern humans and could therefore slip through those tight spots more easily. So, access kinda explained. But how the heck did they see to not get lost?!? Is it understood that homo naledi had mastered fire at this point and could have brought it down there with them in order to navigate? If not, had they the spoken language capabilities in order to relay to their brethren the way down? And what were their motivations for going down there anyway? I’d be fascinated to hear some of the working theories.

    Near the end someone suggests there is a gap between Homo erectus and later hominins, based on the chart which is on the screen before and after 1:24:00. I think the chart is a bit misleading, because the dots representing discoveries are bunched together. There are plenty of remains spread out between 1.5 Million years ago and the later bunch even just in Spain at Atapuerca - 1.4-1.2 Mya Sima de Elefante, 0.8 Mya Gran Dolina, 0.43 Mya Sima de los Huesos - let alone the rest of the world.

    How could prof. John Hawks be sure that the depth and difficulty of passage of the cave system has not changed ever since homo naledis had been using the cave system? We know for a fact that speleothems are formed inside the cave overtime. For all we know, the access to the Dinaledi chamber was not that difficult at all, 250,000 to 350,000 years ago . .

    • @dukeon
      @dukeon Рік тому +1

      Good question. I assume he and Lee Berger have consulted extensively with geologists familiar with that specific area. They would be able to tell by the type and amount of warping of the original horizontal stratification, the forces that acted on the rock containing the cave.
      Lee said in another video that there were actually 2.5 billion year old stromatolites exposed on some of the cave walls, so the rock is incredibly old there (it’s in South Africa, so not a surprise). But how much geologists can actually deduce about the specific structure of the cave as it formed, when it was being used by H. naledi, and from their extinction to the present - I have no idea.
      It would be very interesting to hear that explained. Maybe the area is located on a craton (the oldest bits of continents), which rarely experience any seismic activity or deformation like buckling, since they are made of very hard rock (other cratons are found in Australia, Eastern Canada, and a handful of other places).
      How exactly it can be determined what happened during the last 300,000 years, again I don’t know. Maybe one of Berger & Hawks books or published papers sheds light on that.

    You found many bones in the cave. These are bones from individuals of different ages. At the same time, in apparent contrast to this, there seem to be no signs of social and cultural life (artifacts, leftover food, etc.). Would it be reasonable to speculate that they had taken refuge in the cave, fleeing from some persistent aggressor (the sapiens?), who, on duty, kept them cornered in the depths until they perished from starvation?

    Very interesting presentation. However, some of your remarks about Darwin were inaccurate. For a start, the theory of natural selection was jointly published with Alfred Russel Wallace. And yes, people HAD thought about the "tree of relation of species" before Darwin. For example, Wallace wrote the following in his famous 1855 "Sarawak Law" paper on evolution "We are also made aware of the difficulty of arriving at a true classification, even in a small and perfect group;--in the actual state of nature it is almost impossible, the species being so numerous and the modifications of form and structure so varied, arising probably from the immense number of species which have served as antitypes for the existing species, and thus produced a complicated branching of the lines of affinity, as intricate as the twigs of a gnarled oak or the vascular system of the human body. Again, if we consider that we have only fragments of this vast system, the stem and main branches being represented by extinct species of which we have no knowledge, while a vast mass of limbs and boughs and minute twigs and scattered leaves is what we have to place in order, and determine the true position each originally occupied with regard to the others, the whole difficulty of the true Natural System of classification becomes apparent to us."

    I'd like it if these started being posted with that initial dead air (in this case over 10 minutes) having been clipped out. Also ( 41:14 ) the idea that a tree of relation was a unique idea of Darwin is inaccurate. Carolus Linnaeus, whose published works proceeded Darwin's by over 100 years teetered on the cusp of what Darwin would later actually tack down and well describe. He thought of the relatedness of life being on a sort of tree (there are illustrations and allusions to such in his works). Relatedness was clear to him. He simply couldn't break through his Christain creationist indoctrination in order to discern the mechanism by which obvious relatedness came about.

    It reminds me of the public lectures by thinkers and scientists in the Victorian days and through to the beginning of the 20th century, and how in many parts of the world the normal everyday civilian would crowd into the halls to hear them talk. Darwin faced a crowd like that.
    I find myself feeling sort of down on contemporary culture because the only speakers we crowd in for are like self help gurus and pickup artists. But then I remember that it’s all here, and the numbers of viewers are often, especially over time, far greater than could ever fit in a university hall.
