EXCERPT: . . . 1 to 2 percent of the DNA in non-African people comes from Neanderthals. That genetic legacy is the result of interbreeding roughly 50,000 years ago between Neanderthals and the common ancestors of Europeans and Asians. Recent studies suggest that Neanderthal genes even influence human health today, contributing to conditions from allergies to depression. Now scientists have found that the genes flowed both ways. [...] Based on this gene shuffling, the scientists estimated that humans and the ancestors of the Altai Neanderthals interbred about 100,000 years ago — long before people were thought to have left Africa. “This observation throws a wrench in the works,” said Dr. Siepel....
