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.
Thanks to Julio Lacerda and Fabrizio de Rossi from Studio 252mya for their wonderful hominin illustrations. You can find more of their work here: 252mya.com/

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.

At what point do we separate 'species' in the genus? The point of the video is when did this all occur? There are lots of examples of interbreeding. For example male lion (Panthera leo) and a female tiger (Panthera tigris) creating the liger. So that definition of 'species' is not necessarily related to procreation. Apply 'non-breeding capable' to genus and that might stick. But not species. We have to be very careful to differentiate 'human' from 'hominin'. Such that when we carelessly discuss 'human ancestors' this is not accurate. We H.sapiens are the ONLY humans by definition. We and neanderthals had a COMMON ancestor but they are not our ancestor. Another conundrum: Defining genus. Is pan closely enough related to homo that they could be classified as human? They share a huge part of DNA with us. Never mind the breeding part. I know plenty of humans who for idiopathic reasons can not breed.

PBS Eons I think that Homo Sapiens, Denisovans and Neanderthals are different species. Look at the very stocky / robust skeletal structure and the very differently shaped skulls of the Neanderthal and compare that with ours!!!! I think that the definition of what defines a species needs to be changed. They have discovered that maybe ~2% of modern day Africans contain some kind of 'ghost dna'. No/one knows where it came from. It is most likely comes from Homo-Erectus which is even further back in our lineage than Neanderthals and Denisovans!!! So - does that make us the same species as Homo-Erectus?? Of course not!! If we evolved from them, then of course we can interbreed with them! But to me they are still a different species!

This seems kind of obvious to me... We have Caucasian, African, Oriental, Amazonian, Arabian, Aubergine, Eskimos, Pacific Islanders, etc..... We have multiple deviations of all of these. Seems to me the "missing links" are all around us to include us . Why would it be farfetched to believe that earliest humans spread all over the planet. Some sort of mass extinction destroyed the people that existed in between the connections meaning that humans evolved depending on the environmental needs and eventually reconnected as very different humans We know that we were all able to reproduce so that literally means we all are the same species. Moden humans are just mixed variations. Any thoughts

@EZboyrocks Like many things which we once tried to put into neat catagorical boxes, we are learning that all life exists on a spectrum. Take Bonobos and Chimpanzees, are they two different species, or two societies of the same species as most of the differences are behavioural and dietary rather than genetic. Dogs and wolves can and do interbreed, as do wolves and Coyotes, are Coyotes simply a small wolf? Life is messy, and looks more like a net of interweaving threads then the ever branching "tree" which we used to describe it as.

Yes, there is me: another human species and the video guy, another human species: two different human species gauranteed sir. I discovered why the DNA sequence is most positively accurate without an doubt.

So if we make the assumption that Neanderthal and Denisovan genes have been beneficial, does that suggest that the populations which don't carry their genes (Sub-Saharans) are at a disadvantage?

Neanderthals died out because too many of them believed in Neatherthal-male-privilege and so they stopped making babies.

Awesome info, and great presentation. This is one of my favorite periods in time to study. As a historian, I'm limited to the "high life" of primate existence in the last few thousands years since writing and farming became big news.

Neural symmetry of experiences, (since baby) mimicry~. I don't think that's what genes are nor do. Like that old saying "the apple doesn't fall very far from the tree." Either love them or hate them, still turns out like them unless learn their life's lessons. Photoelectromagnetism, gateways to the soul~. Memories are probably like learned entanglement if overthinking in relation to the sensations recalled. Although, mind over matter, thermodynamics~ I'm referring in a poetic, easy to understand and interpret way or manner. Life adapts to move muscles and efficiently for effectively in relation to usually.

Africans have no other cousin species in them making them truly pure human. And if East Asian and Caucasians ALL have trace amounts, that suggests all of their ancestors resulted from hybridization. I believe that plays a major factor in “race” somehow but 🤷🏽‍♂️

denisovans and neanderthals are not other human species, They are closer to races/ breed. you can not breed with another species.

The narrator in the shirt that's tucked out needs to look more professional. You don't need to wear a suit and tie but you can tuck you shirt in. That way you look less than somebody who's doing this in his garage without the backing of large organizations.
