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

Geneticist and entrepreneur Adrian Woolfson argues that genome engineering and AI will let us design organisms beyond nature’s limits ...

A new study in Science suggests Neanderthal men and modern human women interbred more often than assumed, reshaping theories about our DNA. But what drove those ancient pairings remains uncertain.

Geneticists have a better understanding of how prehistoric pairings unfolded, with new research suggesting they were mostly between male Neanderthals and female humans.

Loss of the Y chromosome in aging men is widespread and increasingly linked to serious diseases, challenging assumptions that the Y has little biological importance beyond sex determination.

Humans and Neanderthals cozied up from time to time when they lived in the same areas tens of thousands of years ago. But we don’t know ...

For years, geneticists have wrestled with a curious absence: many modern people carry Neanderthal DNA, yet large stretches of the human X chromosome are almost empty of it. A new study argues that ...

The researchers also found that Neanderthals had far more human DNA on their X chromosomes than expected. This confirms the ...
