Last year a team of researchers managed to decode two-thirds of the Neanderthal genome. They also found that  contemporary non-Africans share more genetic markers with Neanderthals than contemporary Africans do. Their conclusion was that early modern humans interbred with Neanderthals, and that a few percent of the genes of all non-Africans come from Neanderthal ancestors.

A new, independent study, looking at one particular X-chromosome marker, confirms that finding. You can read the full story here.
