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)

No offense but how can touchy "anti-racists" in bio or anthropology possibly deal with the fact these boundries are clearly waaay more fluid than we ever thought, and the obvious implications

I know that species differentiation can be a little tricky especially in the case of things which can interbreed but do not due to never interacting with other populations or never breeding with a certain individuals (which is the case with some animals like cichlids who are choosy as Hell over mates) though what I am talking about is more relevant to plants, not animals. Plants don't play by animal rules so they may have separate species criteria than animals.

The other species of humans were able to mate with Homo Sapiens because they weren’t at the end of the speciation process. (The process of becoming a distinct species.) Just to add some insight from what I learned in a biological anthropology class.

"[That we are the only hominids left] doesn't mean that Homo sapiens was somehow more fit for survival. The fact is our species became better adapted to local conditions precisely because we interbred with other hominids." There's an argument against racism if I ever heard one.

All Eurasians share a common lineage distinct from the SEVEN haplo lineages only found in Africa, meaning theres literally more genetic diversity within africa than between Scotland and the Phillipines

Well what really happened was Homosapien was scared to venture north for quite some time. Neanderthal and ancient human lived approximately 200000 year together but separately if you know what I mean. They were scared to venture north because the Neanderthal was stronger and actually smarter. They bested the southerners approximately 50000 years on everything especially the creation of glue. Neanderthal discovered that 300000 years ago as where the southern humans were clueless. This completely makes sense because if you see where all the investions came from the last 2000 years they were all from Europe and Asia.

They didn't disappear they became family. Makes more sense because of all the inter breeding between the 3 types. Produced todays humans. So the other ones didn't die off they just joined the population and over years their traits got over taken by other ones. Its all about where the home erectus lived which crafted its appearance and ability. It happend world wide, it wasnt just happening in Africa. So one could say they were all the same "thing" Neanderthals deniso etc. Nature made the DNA differences because of diet.

So if we coyld interbeed and not produce sterile offspring. That meens we were closer than horses and donkeys and zebras and such. Whats the technical difference that makes us not of the same species. One of your other videos stated that house flies from different parts of the world had trouble reproducing with each other and scientists were wondering if they were different species now. Whats up with that?

So you're saying that diversity makes us stronger?
CityCreek Il y a 14 jours
If you mean Genetically speaking yeah! Diversity makes us all around more physically healthy as it promotes widening of the gene pool, recessive traits are more likely to come forward the more closely related two people are (eg. recessive gene for blue eyes) and this also applies to disabilities or inherited diseases. This is why deformaties/illnesses are so common with inbreeding. By widening genetic diversity and the gene pool, a lot of these potentially dangerous genes are on average less likely to appear, though it's always possible. :)

Jammie! Il y a 15 jours
@Widowmaker Technically the burden of proof is on you to prove your claims. Humans are genetically and morphologically less diverse than dogs. All modern humans are the same species, Homo sapiens. Different 'races' do not meet the necessary criteria to be classed as new species. As far as you are concerned doesn't matter, you are wrong and practically all biologists would disagree with you. You are the one making an extraordinary claim that goes against years of established and evidenced science and consensus. Prove that they are different species, release your findings for peer review, change the currently established science and claim your Noble prize.
Widowmaker Il y a 15 jours
@Jammie! Rather sure thats a yes. There are different kinds of poeple out here. We maybe able to breed together, but our offspring sure wouldnt look like either parent. As for as I'm concerned, different species of human. Prove me wrong.
