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

Neanderthals died out some 30,000 years ago, but their genes live on within many of us. African people have very little Neanderthal DNA because their ancestors didn't make the trip through Eurasia, ...

Deep in your muscles, an enzyme called AMPD1 helps turn chemical fuel into usable energy. When it does not work well, muscles tire faster.

When the two species got together tens of thousands of years ago, the hookups may have often involved a male Neanderthal and a female human, according to a new study. The findings, described February ...

A 2026 study finds sex-biased interbreeding, not genetic incompatibility, likely explains why Neanderthal DNA is scarce on the human X chromosome.

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.

For more than a century, Neanderthals have been cast as a vanished side branch of the human family tree, a brief encounter in our deep past. The latest high resolution Neanderthal genome, combined ...

New research reveals that ancient interbreeding between humans and Neanderthals shaped our modern human DNA - especially on the X chromosome.

Females carry two X chromosomes, and males carry one. Therefore, if Neanderthal males and modern human females were mating ...

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