When ancient humans interbred, new research shows that the pairings were predominantly male Neanderthals and female Homo sapiens.

By now, it’s firmly established that modern humans and their Neanderthal relatives met and mated as our ancestors expanded out of Africa, resulting in a substantial amount of Neanderthal DNA scattered throughout our genome. Less widely recognized is that some of the Neanderthal genomes we’ve seen have pieces of modern human DNA as well.

A study shows that interbreeding between the two species occurred primarily in one direction, and the origin of this bias is still unclear

The ability to successfully engage in mass hunts may be what allowed ancient Homo Sapiens to thrive.

Most people alive today carry fragments of Neanderthal DNA in their genome. Now scientists are gaining a more intimate understanding of the ancient encounters that put it there.

Interbreeding between Neandertals and ancient anatomically modern humans primarily occurred between male Neandertals and female humans, a new study suggests
