Kind of difficult, that, seeing how native Americans carry DIFFERENT
Neanderthals DNA. Also Neanderthals & Denisovans interbred, which
means they had to pick up Neanderthal DNA from the Denisovans...
The problem is that modern DNA is NOT I repeat NOT a map of paleo
interbreeding. We know for a fact that the models they are trying
to enforce here are false. We know it. It's just plain WRONG.
HINT: It is generally estimated that, even with descendants, it
would only take about a thousand years to erase you from the gene
pool. Couldn't change the fact that he had lived, or that you had
surviving descendants, but genetically you'd be gone.
You require scenarios where descendants are interbreeding with
other descendants in order to keep any DNA going...
Best example: A man has two children, both daughters. There. In
a single generation his mtDNA and y-chromosome are erased. After
two generations three quarters of his DNA remaining AFTER the mtDNA
and y-chromosome is also gone...
there is pretty good evidence that multiple interbreeding events in different parts of the world occurred between modern humans and Denisovans.
Actually, there's pretty strong evidence for multiple Denisovan
populations about as distantly related to each other as they are
Neanderthals. So, again, the model sucks.
They identify 4 distinct populations of Denisovans that may have interbred with modern humans.
"Modern humans" is a misnomer anyways. It's a cultural distinction,
a "Let's all feel good about ourselves" social program.
