Humans don’t have a defined mating season like deer or wolves. Here’s how evolution blended biology, culture and social life into year-round intimacy.

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

Most people alive today carry fragments of Neanderthal DNA in their genome. Now scientists are gaining a more intimate ...

Long ago, Neanderthals and modern humans interbred. But among Neanderthals, their modern human blood came mostly from their ...

Perhaps human females found Neanderthal males to be high-status providers. Or perhaps Neanderthal society was “patrilocal” — meaning women moved to join the man’s family — while human society was the ...

Geneticists have found an interesting pattern in how early humans and Neanderthals interbred—and it wasn't balanced.

A study out Thursday in Science argues that Neanderthal men and human women were particularly inclined to mate, a sexual habit that offers insight into the evolution of the modern human genome. In ...

Most people of non-African ancestry carry about 2% Neanderthal DNA, and researchers report a mirror image pattern with more human DNA on the Neanderthal X chromosome.

Humans are far closer to meerkats and beavers for levels of exclusive mating than we are to most of our primate cousins, according to a new University of Cambridge study that includes a table ranking ...

Maybe it's not similar interests, horoscope signs, looks, or proximity that make women and men fall in love. According to evolutionary scientists, when people throw up their hands and say "it was just ...
