Neanderthal clues in oldest human genomes
All people, other than those whose ancestry comes solely from sub-Saharan Africa, have some Neanderthal DNA. Now two studies suggest that it entered our genomes virtually overnight, much more recently than was thought. One study finds that modern humans and Neanderthals interbred in a roughly 7,000-year period starting around 50,500 years ago; the other finds that the mixing took place between 45,000 and 49,000 years ago. The results and other insights come in part from the oldest human genomes ever sequenced: a male Homo sapiens found near Ranis, Germany, and a female Homo sapiens whose remains were discovered in a cave at a site called Zlatý kůň in the Czech Republic.
