Neanderthal DNA in Native Americas

[Xenomorph]

Have you people seen the 'denisovan tooth'. It is extremely large compared to any modern or ancient hominins. So far what we have from denisovans is a finger bone and that tooth. But from that tooth alone there's a good reason to speculate that at least the skull must have been enormous.

That may be evidence that denisovans aren't just another race of neanderthals but a separate species, as neanderthals were relatively short and squat.

You are indeed right that they are separate from neanderthals, but they are still closer to neanderthal than to homo sapiens. The first branching starts from the line which leads to modern humans, and then the other that leads to neanders/denisovans, which again later branch from each other. It's difficult to speculate on height, but at least the skull must have been bigger to that of the already impressive neander skull.

I don't know much about native americans but I've noticed some northern native americans have the most unreduced neanderthal features I've seen. Ever.

This guy really looks like a purebred neanderthal.

Notice his very short sloping forehead, very long lower face, long protruding nose, wide mouth and very thin lips.
They're very intresting people, too bad pretty much all individuals who look like the man above are dead.



South american amerindians, however, show pretty much the opposite of neanderthal features. This guy below doesn't even look like he's the same race as the guy above, their facial structure look pretty much as different as that of a Kongolese and a Frenchman. I think we know very, very little about the different ancestral groups of native americans.

I think it's clear they were diverse and not as similar to each other as once though. They might have had less genetic diversity than let's say Africa or Europe but I think it was significant enough . The ones in PR for example were a mix of North Amerindian more recent South Amerindian. The groups had very isolated peoples then more admixed groups as well.

All non-Africans have Neanderthal genes to some degree.

North africans I heard has some too

Well three of my four mixed blood native grandparents had type two diabetes... And the one that is still living and doesn't have it is only 1/4 native.. The rest had much higher percentages.. So at least with my family the Native American genetic propensity for diabetes holds true. If it's from Neanderthals I don't know. I think it would be kind of cool..

North africans I heard has some too

that might be due to the contact of europeans and also middle easterns with north africans, i think he refereed to Sub Saharan populations

Natives don't have neanderthal admixture nor modern Humans. First they only match on some segments of Y chromosomes. And even then theres a huge Chunk of Neanderthal DNA missing on Y chromosomes. They only share from common ancestor before human and neanderthal. If they mixed with neanderthal then Haplogroup Q is neanderthal but its obviously not

Previous estimates based on mitochondrial DNA put the divergence of the human and Neanderthal lineages at between 400,000 and 800,000 years ago. The last common ancestor of Neanderthals and humans — based on the Y chromosome DNA sequenced in the study — is about 550,000 years ago. Scientists believe Neanderthals died out about 40,000 years ago.

I think youre mistaken, the article talks about the Y chromosome not being passed and most likely being extinct, but this doesnt mean modern humans do not have Neandethal dna...

Think like this, i dont have my maternal grandpa Y chromosome, but this doesnt mean i am not his descendant.

You need to start citing me for my work, this information was borrowed from me and consists of my 25 years of work in archaeology and genetics, that is all I ask please

interesting also blood type distribution of certain groups. Vast majority of nearly "pure" to "pure" natives are type O+, but there are seemingly 'random' (not so much) instances of populations with exception- such as the Blackfoot indians of the southwest U.S who have a lot of "A". "B", however, was utterly 100% absent from Native Americans.

Most latinos to this day are still O+.

what is relevance blood type between race,nationality? is O related african,american,natives?i m O but not relation with this
