A new analysis of ancient DNA has found that Neanderthal genomes contain 62 percent more ancestry from anatomically modern humans on their X chromosomes than on the rest of their chromosomes. The finding,

In contrast to those who resided in Siberia, Neanderthals who lived in what's now Belgium and France shortly before the species vanished seem to have been genetically diverse and healthy

NEW YORK — 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 much about who got with whom, or why. A new genetic analysis offers some ancient gossip: The pairings were ...

A geneticist affiliated with Harvard Medical School and the Broad Institute has proposed that Neanderthals did not evolve independently from a separate archaic lineage but instead emerged after early modern humans expanded into Europe roughly 300,

Dating out of your league? New research says it's a tale as old as time. A study out Thursday in Science argues that Neanderthal men and human women were particularly inclined to mate, a sexual habit that offers insight into the evolution of the modern ...

Thin stretches of the human X chromosome look oddly empty when you scan for Neanderthal DNA. Geneticists even have a name for the gaps: "Neanderthal deserts." They sit there like blank tape in an otherwise crowded recording. For years, the standard story ...
