Summary

A piece of bone unearthed in a Siberian cave is providing the most direct evidence yet that groups of ancient humans met and produced offspring. The 2-centimeter fragment contained enough ancient DNA to conclude that it belonged to a woman whose mother was Neanderthal and father Denisovan, the mysterious group of ancient humans discovered in the same cave in 2011. Based on other ancient genomes, researchers already had concluded that Denisovans, Neanderthals, and modern humans interbred in ice age Europe and Asia. The genes of both archaic human species are present in many people today. But the new finding is the first time anyone has identified an individual whose parents were from different groups.
