Scientists Sequence Y Chromosome DNA of Denisovans and Neanderthals
sci-news ^ | 09/25/2020

A growing number of ancient DNA studies on Neanderthals, Denisovans and Homo sapiens suggest intertwined evolutionary and population histories, including several admixture events between early modern and archaic humans.

However, ancient nuclear and mtDNA sequences revealed phylogenetic discrepancies between the three groups that are hard to explain.

For example, autosomal genomes show that Neanderthals and Denisovans are sister groups that split from modern humans more than 550,000 years ago.

However, all but the earliest Neanderthal mtDNA samples are far more similar to those of modern humans than to those from Denisovans.

These studies suggest that Neanderthals originally carried a Denisovan-like mtDNA, which was later replaced through early admixture with early modern humans, likely between 350,000 and 150,000 years ago.

While genomic data for the paternally inherited Y chromosome would help resolve puzzling gene flows, virtually none of the male Neanderthal and Denisovan remains studied to date contain well-preserved Y chromosome DNA.

The researchers found that, like maternally inherited mtDNA, modern human and Neanderthal Y chromosomes were more related to each other than to the Denisovan Y, supporting the suggestion that interbreeding between early humans and Neanderthals and subsequent selection led to the total replacement of more ancient Denisovan-like genetic material in late Neanderthals.

How did the modern humans mate with Neanderthals, that was before beer was invented?

They were travelling on the road for work, staying at low end hotels. And very lonely.

Because they’re cousins. Identical cousins, through and through...

including several admixture events between early modern and archaic humans. >>>>>>>>>>>>>>

I don’t know about you, but I have always felt archaic, that I was not born into the proper time. This science explains it, LOL.

I don't know about you either, but the maternal side of my family comes from Salzburg, where there is a statue in a fountain known as Wilder Mann and legends have it that the Wilder Mann lives in the forest throughout the region. He's bound to be a relative...
