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 Pennsylvania are revisiting a particularly intimate chapter,

Learn how sex-biased interbreeding between Neanderthals and modern humans explains why Neanderthal DNA is largely missing from the X chromosome.

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.

Discover the latest news, features and articles about who Neanderthals were, whether they mated with modern humans and when they died out.

On the slopes of Mount Carmel in northern Israel, a small skull has changed the story of human history. Buried in Skhul Cave roughly 140,000 years ago, the remains of a five-year-old child show that Neanderthals and Homo sapiens were far more intertwined ...
