It Wasn't Just Neanderthals: Ancient Humans Had Sex with Other Hominids - Yahoo! News

It Wasn't Just Neanderthals: Ancient Humans Had Sex with Other Hominids - Yahoo! News: "cientists have collected evidence for years that modern humans interbred with our ridge-browed Neanderthal ancestors in Eurasia. But in Africa, where the homo sapien species is said to have emerged, a lack of genetic evidence has left researchers scratching their heads about exactly how we came to beat out not only the Neanderthals, or homo neanderthalis, but other archaic species like homo erectus and homo habilus. A new paper published by Michael Hammer from the University of Arizona, however, provides evidence that homo sapiens not only interbred with Neanderthals in Eurasia, they also had sex with several species of our ancestors across the African continent. And they did it often. "We think there were probably thousands of interbreeding events," said Hammer. "It happened relatively extensively and regularly."
