Moreover, the researchers determined that the common ancestor to Neanderthals and modern Homo sapiens lived as long as 500,000 years ago, well before the most recent common mtDNA ancestor of modern humans. This suggests (though it does not prove) that Neanderthals went extinct without contributing to the gene pool of any modern humans. Final note
The first humans with proto-Neanderthal traits are believed to have existed in Eurasia as early as 350,000â600,000 years ago with the first true Neanderthals appearing between 200,000 and 250,000 years ago.The exact date of their extinction had been disputed.he finding is that about 1 to 4 percent of the genes of the non-Africans came from Neanderthals, compared to the baseline defined by the two Africans. This indicates a gene flow from Neanderthals to modern humans, i.e., interbreeding between the two populations.
