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.

    A note on "Species"
    Species differentiation as a scientific truth is quite grey now, with all that we've learned even in the last decade. We have found hundreds of examples of species that can interbreed and create fertile offspring once geographical (ie, different side of the mountain range or ocean) or temporal (ie, different flowering times, times of mammal's heat/fertility cycle) barriers are overcome, which is quite easy to do in laboratory settings. Climate change has broken down some these natural barriers to reproduction cross-species, so that it happens in the wild. Temperate-climate bears like the Grizzly and tundra-climate bears like the Polar now have overlapping population distributions, and have interbred. Its possible that some of these more-subtle (ie, noticeable over millions of years, not over decades like in modern history) changes in climate resulted in our interbreeding with Neanderthals.

      The other interesting thought is the FOXP2 gene in Neanderthals, which affects linguistic abilities. While this is a hypothesis, I have a feeling that they may have had an influence on our languages. We'll never know for certain, though.

        isn't the concept of a "Tree" as analogy becoming a poor metaphor to represent life?

            Are you saying there are genetic differences between the races? I thought race was a social construct

              I mean, there are genetic differences _within_ races too.

                Can we all just agree humans didn't out compete them to their demise. They were killed off by a catastrophe. Probably a astroid raised tsunamis and killed a lot of them off. Especially when you think about how benefitial it is to live by the water.

                        Interesting how a lot of these Neanderthal remains were found in the Balkans... you should do a video on the ancient Vinčan culture, located in modern day Serbia. These were some of the first European settlers.

                                    The concluding lines "They live on in our genes, reminding us of a time when we weren't alone", kinda makes me sad for the Neanderthals ...

                                        By definition, if we interbred, then produced viable offspring, then we're the same species.

                                                In essense he is saying so, you share the absolute vast majority of your genes with these groups, the differences being in how these genes are being presented physiologically. An aboriginal may have a bigger brow ridge, darker skin and shorter build than a caucasian, but they still have vastly more similarities in function of organs, psychology and physiology than say you and a chimpanzee, our closest (known to science) living relative that is a separate species.

                                                So yes, you're by definition the same species as an aboriginal australian, a subsaharan african, a han asian, a caucasian, a native-american, a sami, really any living human(that is known to science).

Also, you said the reason we know the stat2 comes from neanderTHALS because it isn't found in that specific area of Africa. Wasn't it recently found out that we didn't originate from Africa as we used to believe?
