When We Met Other Human Species

    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.

    It seems illogical that our species could successfully breed with a different biped species. Of course there are several variations of our species but we are all of the same species.

    They weren't different species. I'm a reptile handler enthusiast in Australia and there's perfect examples of one species looking so radically different, with vastly different hunting strategies, egg-clutching behaviour, and general size and appearance ... and yet they're the same species. The common carpet python and the diamond python. Both of them morelia spilota... Their personalities, colouration, hunting strategies, and even their average clutch sizes are wildly divergent. Both of them interbreed and produce fertile young. Both of them produce hybrids. That being said, in the wild they had become geographically locked into different environments with the Holocene epoch, and over thousands of generations have become very different looking and behaviourally incongruent subspecies of the whole. And these differences are worlds apart on their own, just not enough to create two distinct species. Another common example? Dogs. All of them have been carefully bred and undertaken significant animal husbandry that you can have dogs the size of your hand, to dogs that weigh as much as a person. Still the same species.

    @Olav big cats can breed even hybrid ones male or female.theyre are more likely to be sterile.thats all. and species is a word used to describe compatible breeders. if 2 things can breed they are the same species

    If we can interbreed with them, are they even a different species? Or: Are Europeans and Asians even the same species as subsaharean Africans if they differ in particular genes and are mixed with neanderthals?

    Why are the different races of humans not treated as separate sub species? They’re obviously distinct and evolved and adapted in their own different environment, I mean humans change and evolve just like every other animal

    How much modern human DNA has been found in non modern human specimens. I have a theory that modern humans screwed and out screw our ancestors and cousins into extinction. Climate change a factor an well. But the fact that mitochondrial DNA was found suggest that we were sticking it to everything we could and population estimates suggest that the other humans weren't spreading their seed as prolifically. Therefore unable to keep up with our reproductive rates and falling victim to humanoid lust eventually were absorbed into the modern human species. One can also argue that were a subclass of the same species since we could successfully reproduce without producing sterile offspring. Hmmm, one to grow on.

Scientist A no but there are so many easily deceived people who are willfully ignorant and ready to believe anything that they will accept this knowledge as fact! "Scientist B" oh yeah those democrats will believe anything, maybe you can convince them to sell their soul, kill their babies, worship idols, pedophiles, actors, pop singers, athletes, money, themselves, and maybe even Bernie Sanders?

    So question since the Neanderthals headlong gated skulls and they were not from Africa then why did the Egyptians worship this elongated skull. Why did wrap their infants heads to make them elongated?

    Just to add: the narrative about the lack of Neanderthals genomes in sub Sahara Africa is not correct, because of many back migrations from Eurasia to Africa. It's obviously with the people in Eritrea and some Ethiopian folks, but also in Nigeria, South Africa etc are tribes with Eurasian ancestry DNA from breeding, especially in the last 6000 years.
