But just as interesting, perhaps, is what the researchers did n’t find.
Researchers found very little Neanderthal DNA on humans’ X and Y chromosomes, suggesting that interbreeding among modern humans and Neanderthals happened near the end of our divergence.
“This suggests that when ancient humans met and mixed with Neanderthals, the two species were at the edge of biological incompatibility," Reich said.

Die Forscher fanden sehr wenig der Neandertaler-DNA auf den X und Y Chromosomen der Menschen, was darauf hindeutet, dass die Kreuzung zwischen modernen Menschen und Neandertalern gen Ende unserer Divergenz stattgefunden haben muss.
„Dies legt nahe, dass, als antike Menschen sich mit Neandertalern mischten, sich beide Arten am Rande ihrer biologischen Unverträglichkeiten waren,“ sagte Reich.
