Asian Neanderthals, Humans Mated

Early modern humans mated with Neanderthals and possibly other archaic hominid species from Asia at least 100,000 years ago, according to a new study that describes human remains from that period in South China.

The remains are the oldest modern human fossils in East Asia and predate, by over 60,000 years, the oldest previously known modern human remains in the region.

The fossils -- a chin and related teeth -- belonged to a modern human that also featured more robust Neanderthal-type characteristics, indicates the study, published in the latest Proceedings of the National Academy of Sciences.

Co-author Erik Trinkaus, who is one of the world's leading experts on Neanderthals, told Discovery News that the new findings mean "there was mating between these 'archaic' and 'modern' groups across Asia, and not just in Europe and the remainder of Africa."

"Of more interest than who had sex with whom is the fact that modern humans had spread across southern Eurasia by 100,000 years ago, and yet archaic humans remained across the more northern areas, and even displaced the modern humans in Southwest Asia for an additional 50,000-70,000 years," added Trinkaus, a professor of physical anthropology at Washington University in St. Louis. "It argues for very little adaptive advantage on the part of these modern humans."
