The team of European scientists led by Pääbo Sventa (Svante Paabo) held at Stanford University (Stanford University) study, which proved a high probability — the mixing of early humans and Neanderthals did not happen.
For many years, scientists have debated: could it be that when early humans spread to the north (to Europe from Africa), 30 000 years ago, they interbred with Neanderthals, who already lived there, said anthropologist Richard Klein (Richard Klein).
Earlier this testimony were looking for, mainly by examining the fossils.
Now, isolating mitochondrial DNA from four Neanderthals and modern five people named European scientists have found no evidence of a significant genetic transition.
This should not mean that there was no mixing at all. But this could be only a few cases, did not influence how much or whether, on the genetic development of the "sapiens".
However, for more precise conclusions need to spend even more comparisons — too few samples.
Klein suspects that early humans and Neanderthals were very different in appearance and behavior to find in each other's romantic interest. "It's not that they could, maybe, but they're probably just not interested in it" — said the scientist.
