When We Met Other Human Species

  • Published on: 09 July 2019
  • We all belong to the only group of hominins on the planet today. But we weren’t always alone. 100,000 years ago, Eurasia was home to other hominin species, some of which we know our ancestors met, and spent some quality time with.

    Some commenters have pointed out that calling Neanderthals and Denisovans “other hominin species” in this episode breaks the rules of the biological species concept (BSC), which says if two things can interbreed, then they’re the same species. Some paleoanthropologists would agree. They consider both Neanderthals and Denisovans to be subspecies of Homo sapiens, rather than separate species. Other experts would say that Neanderthals have a set of features that make them clearly distinguishable from Homo sapiens, putting them outside the range of variation we include in our species. And we hardly know the Denisovans - like we said in the video, they don’t even have a scientific name yet.The incredible thing about this is that we can even think about applying the BSC to fossils at all. The BSC is a species concept based on living organisms, and it’s only been within the last two decades or so that we’ve had the ancient DNA and the technology to test hypotheses about interbreeding in extinct groups. And it’s not the only way to define a species, either, so it will likely be a while (if ever) before anthropologists decide whether we’re a different species, subspecies, or population from the Neanderthals and Denisovans.(Darcy Shapiro, PhD, script editor)

    Neanderthals didn't just go extinct but was genocide off by the Cro-magnum. The evil side of our human nature.

    Resistance is futile! We will absorb your technology and DNA into that of our own! Yes, we used to think that we hunted you all down and killed you all to extinction, but now we think that we were your friends and relatives and you all died out own your own and we alone are left to carry on your legacy!!

    Actually, there exist many archeological sites with findings of bones of mass-murdered people of all sexes and ages, who were clearly killed with a use of human-made weapon, so I believe that if Homo Sapiens Sapiens were able to do that to each other (even long after the Neanderthals went extinct), than I supposed they would be just as able to do that to any other hominids.

    Despite all evidence of human behavior throughout history, we're asked to consider the proposal that humans who would've been in direct competition with (other tribes of humans as well as) Neanderthals and Denisovans DIDN'T actively wipe out those less adapted species.It's a cute flight-of-fancy but very contrary to all historical precedent.

    Thanks! Although I know there's no evidence for it - or against it, I can't help but seriously wonder if there was some bit of nastiness that led to us being the dominant hominin. I certainly wouldn't put it past us, knowing modern history. 𝓡𝓲𝓴𝓴𝓲 𝓣𝓲𝓴𝓴𝓲.

    If people from eurasia have such a different DNA content and origin from sub Sahara africans, would not that mean that they are a different species? Or variations of sub species?

    If the purpose of life is to pass on genes to the next generation all the other hominids were successful.

    So we don't know what sub species of hominid sub Saharan Africans had dalliances with? But Europeans were oh look, the lady has some fine thick brow ridges. Imma get me a piece of that... Sounds about right.

    It makes sense the Neanderthal genes are still in many people, I have actually met people that have features similar such as big brow ridges.....
