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.

    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.

      PBS Eons they need to be looking at the specific blood types. People should consider that we are the product of other types of beings. Rh- folks for example have an extra vertebra as well they have more copper streaming in their blood, making them far more conductive! These things are important to consider when looking at our ancient ancestors or root races. Then we must always remember that the truth is right inside all of us, safely stored in our DNA. Time to start researching inwardly💚💫

      @pauldh62 That's essentially true, as far as I can tell! So resonably, dogs could be considered a subspecies of wolves. But dogs can interbreed with coyotes and jackals as well, which are also considered to be separate species.

      @Warner Losh My limited understanding is that a dog and a wolf are actually one and the same in terms of species. The former, however, has been subject to generations upon generations of selective breeding. The only problem one would have with trying to mate a dog and a wolf out of the laboratory would be preventing the wolf eating the dog -they do.

      There are interspecies hybrids in nature. Look at Cuora seratta for example that comes from two separate turtle species within two separate genera. The hybrids are fertile too!

      We are the neandarthals. They did not get extinct. This nonsense theory called out of africa has no basis. Africa has no civilization , all traces of greatest Human civilizations are around mediterranian sea and fertile crescent. Yet the fools insist on something ridiculous because of politics.

                              So, Native Africans, who never migrated and met others, are the only "true" Homo Sapiens. There is more diversity of DNA in Africa than anywhere else in the world...the more diverse, the genetics, the healthier the body.
                              The combination of inbreeding and interbreeding, by western man, has diluted the bloodline of "true" humans.

Maybe Darwin was right about evolution.. Just not talking about Africa or its descendants.. Neanderthals are cavemen. Very similar to primates. T

                                                      If DNA attributes are derived from longevity of one's life (more intercourse) spreading the DNA. Then are modern humans destined to fail if we only pass along DNA through what monetary means we derive in life presently. In short... if a bunch of rich idiots have greater means in life than genius poor population are we destined for failure as a species?

                                                                                I would like to point out that Neanderthals and certain other hominins probably did not go extinct.  Their much smaller populations merely got absorbed into the larger Homo sapiens population.  This fits in with the small bits and pieces of their DNA found in our genome.  And how do we know they are in fact hominin DNA sequences in our genome?  Perhaps its our DNA sequences that scientists found in their genome.   I personally think too many scientists jump to conclusions without thinking logically through the evidence.  How do we really know which group gave their DNA to the other.  Most likely there was a lot more DNA swapping going on throughout our prehistory that we do not know about.
