    I think some people have more Neanderthal DNA in them than others?

    Lol all just humans , have you ever seen a Australian Aboriginal skull and bone structure to Caucasian or even Latino , completely different , still human .

    It’s so interesting to see people thousands and thousands of years ago , especially what they looked like and what thousands of years of reproducing does.

    These interbreedings are more likely the results of raping than ... hanging out. Stop glorifying the history please.

    Gonna be honest, I thought that neanderthals were just part of the evolution of humans. I literally had no idea that there were ever multiple species of humans living at the same time. This video was super informative and introduced my nerdy ass to a really cool new topic for me to aggressively research. Thanks!

    I would like to see a video that explain why Aborigines look so different then other people, like how they got the skin color of Africans and other dark skinned people, like Indians from India and others of southeast Asia, but yet looks so different...

    Pronunciations aren't vital to the discussion, and they seem to change so often that I don't reserve any brain power or space to trying to re-memorize the way to say a term, as when I apparently "mispronounce" a name, the listener still understands what I'm speaking about.

    We assimilated them, we added their biological and technological distinctiveness to our own, their culture adapted to service us, resistance was futile

    I don't buy that they couldn't adapt to environmental changes, because they were around for nearly 500,000 years, and lived through at least four ice ages. More likely to be either natural selection due to their low population, or modern humans brought all kinds of diseases which killed them, as the Europeans did to the Americans 150 years ago.

    I've heard one theory of the reason we beat out the Neanderthals was because we had a much higher ability of communication and also a better ability to use abstract thought which let us adapt to things easier and also allowed us to have larger and more prosperous communities.

    I sometimes feel a strong longing to NOT be alone. To have other groups of humans around us. I know the world would probably be even more racist and ableist if we had more human species, but on the other hand there would be even more diversity, and I'd just love to know how we would all fit in together in modern society. What would these other species bring that we haven't come up with? Maybe in a few hundred years we will bring them back by cloning them with old DNA.

    According to the definition of species, if all those hominids could have had common descendants, they belonged to the same species. Or sub species are implied?

    Honestly I wasn’t expecting him to say we met them and interbred with. I was expecting him to say we met them, and then we killed them.

    If they mate then they are from the same species, that is one way to define what a species is...

    Dingus - Games, vlogs, and more?Day ago

    Awesome video! Also, I've heard of another hypothesis about why the neanderthals were not as successful was due to lacking vocal abilities. While they could speak, they were nowhere near the capabilities of Homo Sapiens and this would have affected their ability to resolve group conflict, hunt, and fight/defend together. Over thousands of years that could chip away at a population. Not saying this is the SOLE reason, their demise was indisputably caused by many issues, just my two cents!

    It's probably most likely all the things you listed are the reasons the neanderthals. They were on their way out because of the ice age, and whenever homo sapiens migrated north they out commpeated them in many areas, they then started inter breeding and because of their low numbers they were interbred into the homosapiens gen pools. The remaining were probably out compeated whenever dogs were domesicated and homo sapiens sphear technology.

    It's very reassuring to know that homo sapiens bred with neanderthals, now we know that the hybrid is Sasquatch. The tradeoff? We got dwarfism, sasquatch got giantism.

    The most recent evolutionary split among hominids is to be found in the USA. an odd collection of humans that deny scientific facts in favor of "alternative facts". Truly bizarre.

    If today the neanderthal lived, the homo sapiens would have used them as slaves . We as humans cant even tolerate other races of our same species. Imagine if the species were different We are less evolved than our ancestors. We are more divided than our ancestors were. Our ancestors survived because they learned to coexist. We will die cos we forgot to co exist

    A note on "Species" Species differentiation as a scientific truth is quite grey now, with all that we've learned even in the last decade. We have found hundreds of examples of species that can interbreed and create fertile offspring once geographical (ie, different side of the mountain range or ocean) or temporal (ie, different flowering times, times of mammal's heat/fertility cycle) barriers are overcome, which is quite easy to do in laboratory settings. Climate change has broken down some these natural barriers to reproduction cross-species, so that it happens in the wild. Temperate-climate bears like the Grizzly and tundra-climate bears like the Polar now have overlapping population distributions, and have interbred. Its possible that some of these more-subtle (ie, noticeable over millions of years, not over decades like in modern history) changes in climate resulted in our interbreeding with Neanderthals.

    The other interesting thought is the FOXP2 gene in Neanderthals, which affects linguistic abilities. While this is a hypothesis, I have a feeling that they may have had an influence on our languages. We'll never know for certain, though.

    Can we all just agree humans didn't out compete them to their demise. They were killed off by a catastrophe. Probably a astroid raised tsunamis and killed a lot of them off. Especially when you think about how benefitial it is to live by the water.
