Unknown Human Lineage Found Buried in The Neanderthal Genome Story by Russell McLendon Ancient Human Skull© Provided by ScienceAlert As Homo sapiens migrated into Eurasia more than 70,000 years ago , much of the continent was already inhabited by Neanderthals, hominins who shared an ancestor with us but had spent roughly half a million years diverging. We don't know much about their ensuing relationship, but it was probably contentious at times. While Neanderthals eventually disappeared 40,000 years ago, there are now 8 billion of us. During their Late Pleistocene overlap in Eurasia, however, we know the two hominin species sometimes interbred, since many humans today still have traces of Neanderthal DNA. And according to a new study, this relationship goes back even farther than we thought, with a long-forgotten earlier chapter re-emerging from clues in the Neanderthal genome. When modern humans reached Eurasia in the...
