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:

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. (Darcy Shapiro, PhD, script editor)

The only suitable definition of "we", as used in this video, should be the population of all humans alive at the present. It seems to me that saying "we interbred with Neanderthals and Denisovans" makes no sense. In others words, non-africans are descendants of many interbreeding events between very different people who [all of them, early or late,] descended from africans... Now yes, WE can dive in the fascinating part without getting stuck with categories or dangerous assumptions. (sorry for my bad english)

So if subsaharan africans don't have that gene they must have another for that immune response?

@Olav Well said! Think also of Horses, Donkeys & Zebras. SIMILAR, but different. What are bloodtype for? My hypothesis: A way for our Star Ancestors to keep track of their experimental Genetic Breeding Program to Interbreed Species, as proven from stages of embryonic growth in human fertilized eggs.

1960-1990: human species were depicted with long hair. 1990-2015: early humans were given dreadlocks. 2015-2025: early humans are depicted with man buns or short hair. you guys need to get your hair styles in order.dreads are unlikely because lice can breed and hide in dreads. man buns are unlike because rubber bands were not invented until the 20th century. long hair also makes less sense than short hair because of the problem with lice. short hair styles make the most sense for at least 90% of early humans.

So if a people is a crossbreed between two species they are a new subspecies. So central Africans are true surviving Homo Sapiens, Europians and Asians are Homo Sapien Neanderlis and Aboriginalpeople of Oceana are Homo Sapien Denisiva. It's aslo a bit stupid that Homo Sapiens are called so for being capable of thought when its clear so did many ancient hominims. They should be reclassified as Homo Homo to say the same as us or Homo Africanis

I still only accept the original pronunciation of denisovans (first that i heard many times). This is English, we can make anything sound however we want. Em-phas-iss on a different syl-obb-le. We do as we please. 2nd most spoken language on earth backs that up. Denis-ovans. I will never call it anything else. Im 76% german and can only speak english...i am living evidence that this plan works.

So the reason why some people are taller or shorter is because the ancestors of homosapiens mated with other hominin species like the neanderthal or denisovans?

I think there there was some sort of human genetic engineering going on to get what we have as modern humans today from some unknown source... I think it's interesting that we're the only human species left that survived and evolved to what we are today.

I wish we had a kind of telescope that rather than looking through space, can look back in time. It would be so awesome to know for a fact what did and didn't happen to bring us to the point we are at now!! Not knowing exactly what happened in the distant past has always been a source of deep frustration for me (and many others as well I'm sure!) :)

"Modern" humans might be the common ancestor of 2 or 3 completely different hominin species in the distant future. Despite being a global community now, I still see a few scenarios where that could happen. If the Sentinelese remain permanently isolated (and survive long-term), our genes would inevitably drift apart. This, to me, seems like the most likely way. Additionally, a Martian colony could lead to genetic isolation. Although futuristic technology might make the huge distance between Earth and Mars irrelevant. Maybe an extinction event and the resulting technological "reset" would lead to genetic isolation as well, but we'd probably find ourselves dominating the planet again eventually (if we aren't wiped out completely).

What would be interesting is to obtain a genetic layout of WHICH specific genes Europeans share with Neanderthals. We may be slightly different Neanderthals than our Neanderthal ancestors but Neanderthals nonetheless. Humans share 98/99% of genes with Bonobos so the 2% Europeans share with Neanderthals may be VERY important raciation genes which would be sufficiently prevalent to maybe allow us to say that Europeans and particularly northern Europeans are indeed primarily Neanderthals....since they were fair skinned, blond and red haired, blue eyes "people".

Well, by our modern definition of subspecies, we can say that different human ethnic groups are subspecies. But people will accuse you of racism if you bring it up

I though this was going to be more morbid. I personally have read articles about dehumanizing other species of human, especially during circus freak shows or native human exhibits. The majority is particularly, the survival of the fittest but imagine a world with more peaceful cousins.

Can they really be considered "other human" species when those other human species are our ancestors? It seems modern humans are more a mixture/hybrid of multiple hominid species rather than the lone branch that survived. It is a result of interbreeding between different hominids and that's why we have modern humans that can trace their genetic ancestry to neanderthals, denisovans and others. I would like to think that they didn't really die out, they just became a part of modern humans and their legacy lives on with us.

Is it only me that became kinda sad that we don't have different hominin species around? It is as sad as killing off the cultures of South and North America. Those people today could have totally different culture than the rest of the world, imagine the architecture, language and science focuses differences we would have. Similar to how for example European and Asian and Arabic architecture is completely different, and all equally interesting. Even the most modern buildings are different from continent to continent with distinct features. Wish we could come back in time.

Help me help you to understand we as a species have always been evolving. Still today there are many different breads of humans, open your eyes. In the future more will meld together to make the next best thing (melting pot). I wonder if racism existed 10K years ago. The answer is yes. Life was hard then and history repeats itself.
