When We Met Other Human Species

  • Published: 10 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.

        Science always expects belief, even though they have no problem tossing their former "facts" into the trash bin...:-)

          So subsaharan people are close to 100% pure while the rest of us have our ancestors mating with Neanderthals? I wonder if we can freak out some KKK members.

            Imagine if there was another continent FULL of Neanderthals. What would you do?

            When modern humans met Neanderthals, of course they fought each other. This is the case today and into the future.

              Did the Neanderthals have different races? Ditto Homo sapiens of the time.

                It's crazy to keep saying "we" and "they"; we're both part part of human evolution. It should be looked at as a merging continuum instead of compartmentalized. Neanderthals didn't go "extinct." They were simply merged into the evolving modern human, and because the product was superior, Neanderthals faded away. I'm sure Homo heidelbergensis from around 500K years ago and Homo antecessor 1 mill. years ago will be proved as our descendants as well.

                    Why are you ignoring substantial evidence of earlier traces of human in the americas, people have been disregarding this for years now I don’t understand why

                      So very interesting. I think hominin divergence is still taking place up to now, now, and in the future. Phenotype follows genotype up until the point where interbreeding results in no viable offspring. Observe the cultures around you and think.

                          Guys just imagine if other homonin species have reached to AUSTRALIA, did you know that the fisrt people on Austrlia get there like 40000-50000 years ago?, years before the other hominin species died!

                              There's only one human species, one biological human race. The world view of "multiple human races/species" is one of the reasons why racism, racial supremacism, and prejudice still thrives.

                                So.... racism is stupid as there's only one human race. But Eurasians have Neanderthal DNA and others don't?

                                Scientifically if homo sapiens which are a separate species from homo neanderthalensis, went back and crossbred how are the progeny of this mating still considered homo sapiens when it is a half breed of both species. Would that not mean those offspring are a completely different species......

                                A Leopon is a cross between a male leopard and a female lion, however, the offspring is a species of combined origin but it is not classified as a lion or leopard.

                                    There's been a recent discovery that's the gist that Neanderthals couldn't obtain as much nutrition from tubers

                                      Thanks for the video I think these facts mean something really cool :-)

                                      I still do not get the notion of extinction here xD
                                      The homo sapiens was more numerous so it is logical who "absorbs" whom^^...

                                      As you said - they live still within us ;-) would not quite fit my notion of extinct only because there is no "pure" version left :-P

                                        I would love to see what a Neanderthal-Homo Sapien hybrid would have looked like from the first generation onward.

                                          Maybe in one-hundred years or so scientists will discover that we are immortal souls that simply move from body to body over time.....or NOT!

                                            Just one small comment: you talk about a gene EPAS1 then show a protein on screen with the label EPAS1 but never make clear that the gene is not the protein. Genes are used to create proteins.

                                                Denisovans and Neanderthals aren't different species from homo sapiens - They are simply subspecies. What happened is that they simply joined in. Initially it was like 10% neanderthal, 90% sapiens as the flood of immigrants from Africa came in. Eventually the huge quantity of Homo Sapiens marginalized the former lords of the continent to around 1%-2% in the genetic record. They didn't go extinct, they simply merged with the rest of us. They lived with us, hunted with us, loved with us and that's all. I know it's not as "romantic" as a tale of a huge war between the Neanderthals and the Homo Sapiens - but we have absolutely no proof of such war. We do have proof of making love, not war. A bit more romantic.

                                                      Could this possibly be the basis for our cultural creation of Dwarfs, Faries, Elves? All Human Cultures have these "other human creatures" in our myths, stories, and oral traditions. Could this be the way that modern humans attempted to explain to their descendants that there were "other human creatures" like us long ago?
