Neanderthals, Denisovans and us: A Paleolithic ménage à trois Geneticists studying bones from a Siberian cave recently made a startling discovery: A half-Neanderthal, half-Denisovan girl. It's direct evidence — "almost caught in the act, so to say" — of something scientists already had some proof of: that the two hominid species had interbred. We know from our own genomes that both species interbred with our ancestral Homo sapiens, as well. |
