Turns out our human ancestors and Neanderthals were mixing it up 100,000 years earlier than anyone thought! Scientists just found a 140,000-year-old child’s skull in Israel with features from both species—proof that the two groups were getting together way before the previous record. Basically, if you’ve got a little Neanderthal in you, it goes way deeper than we realized. Wild, right? #Science #Neanderthal #HumanEvolution
