DNA from a roughly 37,000-year-old Homo sapiens skeleton supports recent findings about when ancient humans and Neandertals interbred and other details about human evolution. In October, scientists reported on ancient DNA that suggested Neandertals and Homo sapiens hooked up between 50,000 and 60,000 years ago. The analysis of the slightly younger human bone, found in Russia, narrows that range to approximately 54,000 years ago, researchers. The individual's and his relatives' genomes may have also been influenced by an even more ancient line of Eurasians that provided the foundation for the genomes of modern Europeans, the scientists suggest.
