For instance, an ancient human who lived in what is today Romania had 9% Neanderthal DNA. Today, most Europeans and Asians have between 1 to 4 percent Neanderthal DNA.

That was until last year, however, when anthropologists convened that the two related species did indeed mate, but the genes passed down from Neanderthals were inactive.
