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.

      Sometimes I wonder. If a paleontologist found fossils in different parts of the world would they classify Pygmies (about 4 ft tall( as the same species as Zulus (about 7 ft tall.) What about Bushmen of the Kalahari, or Asians, say Japanese. or Australian Aborigines. Or Mayans? Would these all be classified as the same "species"? Again, remember, I talking about dead fossils.
      I recently saw an Tyrannosaur exhibit at the American Museum of Natural, where they've recently identified that small T-Rex-like "species" are actually the same species of Tyrannosaurus Rex, but at different ages: baby, adolescent, young adult, adult.

      @Flightrisk When we have thoroughly aired this one 50 to 100 years from now I reckon there will be several more brothers or sister human species discovered, all assimilated with Sapiens Sapiens.

      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.

        Maybe they didn't die out, maybe we all just made love and there were more homo sapiens than Neanderthals or Denisovans so more of our DNA ended up in the batter.

                  Florensis - Hobbits
                  Neanderthals - basically dwarfs

                  So basically some of the most prominent species from the Fantasy genre are based on ancient relatives?

                          Personally I think what have Homo sapiens Sapiens (modern humans) an advantage is our ability to adapt rapidly. Wether that’s through more advanced technology or through interbreeding with species adapted to those locations

                              Basically, they were ALL HUMANS of SOME kind. Why be so species-ist. They were all conscious hominids. We were just the trickiest, luckiest and probably the most aggressive, lets face it.

There is more diversity of DNA in Africa than anywhere else in the world...the more diverse, the genetics, the healthier the body.
