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.

          If they mate then they are from the same species, that is one way to define what a species is...

            Awesome video! Also, I've heard of another hypothesis about why the neanderthals were not as successful was due to lacking vocal abilities. While they could speak, they were nowhere near the capabilities of Homo Sapiens and this would have affected their ability to resolve group conflict, hunt, and fight/defend together. Over thousands of years that could chip away at a population. Not saying this is the SOLE reason, their demise was indisputably caused by many issues, just my two cents!

                It's probably most likely all the things you listed are the reasons the neanderthals. They were on their way out because of the ice age, and whenever homo sapiens migrated north they out commpeated them in many areas, they then started inter breeding and because of their low numbers they were interbred into the homosapiens gen pools. The remaining were probably out compeated whenever dogs were domesicated and homo sapiens sphear technology.

                    It's very reassuring to know that homo sapiens bred with neanderthals, now we know that the hybrid is Sasquatch. The tradeoff? We got dwarfism, sasquatch got giantism.

                              The most recent evolutionary split among hominids is to be found in the USA. an odd collection of humans that deny scientific facts in favor of "alternative facts". Truly bizarre.

                                Wait, if they were a different species how did they were able to reproduce with homo sapiens?

                                  Could someone explain me why they were a different species if they could interbreed with us? Isn't that against the definition of species?

                                    If today the neanderthal lived, the homo sapiens would have used them as slaves .

                                    We as humans cant even tolerate other races of our same species. Imagine if the species were different

                                    We are less evolved than our ancestors. We are more divided than our ancestors were.

                                    Our ancestors survived because they learned to coexist. We will die cos we forgot to co exist

                                      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.

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

                                                                            However there are also definitions which only take into account the physical characteristics which are present in the two individuals, many tree-species are defined as such, mostly because one can cross-breed many tree species and produce viable offspring.

                                                                            I agree that PBS-eons should have probably clarified which definition of species they used, however one can surely, from context, ascertain that they are not using the typical well-known definition that you're describing.
