Neanderthal DNA is not distributed evenly throughout the human genome. Scientists say the explanation may be mating behavior.

Humans and Neanderthals cozied up from time to time when they lived in the same areas tens of thousands of years ago. A new ...

A genetic analysis reveals that ancient pairings between humans and Neanderthals favored female humans mating with male Neanderthals, shedding light on their interactions.

Since 2010, scientists have known that Neanderthals and our ancestors had offspring together, and those hybrid babies passed down their genes to many present-day people. But the idea of “archaic ...

Geneticists have a better understanding of how prehistoric pairings unfolded, with new research suggesting they were mostly ...
