In a genetic analysis of 379 Europeans and 286 East Asians, Vernot and Akey identified unusually long chains of gene variants that people probably inherited via Stone Age interbreeding, presumably from Neandertals.
The groups could share plenty of genes with little or no interbreeding if small bands of Homo species in Europe and Asia hid out in isolation during ice ages (SN: 4/7/12, p.
Other studies have found that ancient interbreeding may not be necessary to explain the presence of Neandertal DNA in modern humans.
The professor told a meeting of the Royal Society in London that this interbreeding instilled modern man with a "hybrid vigour" that allowed it to go on and populate the world.
The evidence for past interbreeding is convincing, says Richard "Ed" Green, a genome biologist at the University of California, Santa Cruz.
Competition for the same resources created an intense rivalry that discouraged interbreeding, many researchers claimed.
Some anthropologists regard Neandertals as a subspecies of Homo sapiens and see the genetic evidence of limited interbreeding as supporting that view, but those anthropologists are in the minority these days.
It was known that Homo sapiens bred with Neanderthals after leaving Africa, but what wasn't known is whether the interbreeding made any difference to their evolution, New Scientist reported.
DNA extracted from a 40,000-year-old pinky bone and a 100-year-old lock of hair has provided glimpses of two Stone Age human migrations to Asia, including an early foray marked by interbreeding between ancient people and some mysterious, well-traveled members of the human evolutionary family.
Swedish biologist Svante Svante Pddbo's team at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany have found the first definitive evidence of interbreeding.
The discovery comes as a big surprise to some researchers who have been searching for genetic evidence of human-Neandertal interbreeding for years and finding none.
The best way to explain that variation was if there were two periods of interbreeding between humans and an archaic species, such as Homo neanderthalensis or H.
