By now, it’s firmly established that modern humans and their Neanderthal relatives met and mated as our ancestors expanded ...

The human genome is a rich, complex record of migration, encounters, and inheritance written over thousands of millennia. Genomic research by members of Sarah Tishkoff's lab at the University of ...

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

Add Yahoo as a preferred source to see more of our stories on Google. A new study shows how three Neanderthal DNA variants strengthened a key enhancer for jaw development, offering fresh insight into ...

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, ...

Geneticists are now tracing specific traits and disease risks back to encounters between early Homo sapiens and Neanderthals tens of thousands of years ago. The emerging picture is not that we are ...

Most people with non-African ancestry carry roughly 1–4% Neanderthal ancestry spread across their genomes, a legacy of contact after modern humans expanded into Eurasia. But the X chromosome, one of ...

Humans today often carry around a small chunk of DNA from Neanderthals, suggesting we interbred with our closest known extinct relatives at some point in our history. So why isn't there more ...

A new Neanderthal DNA study suggests interbreeding between modern humans and Neanderthals favored pairings of female humans with male Neanderthals. This finding challenges traditional evolutionary ...

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

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