The genetic similarities between certain human populations and Neanderthals are striking. Indeed, many researchers think the Europeans and Asians inherited between 1 and 4 percent of their DNA from Neanderthals, yet scientists have struggled to demonstrate with a high degree of certainty that these genetic similarities are the result of interbreeding between these two species. Now, a pair of European scientists say that they have confirmed the human-Neanderthal reproduction hypothesis using statistical modeling — and these results, the researchers add, should go a long way to change the way we think of other human-like species.
