Native Americans are 1/3 European?

According to new research, Native Americans may be up to 1/3 European.

SANTA FE—Where did the first Americans come from? Most researchers agree that Paleoamericans moved across the Bering Land Bridge from Asia sometime before 15,000 years ago, suggesting roots in East Asia. But just where the source populations arose has long been a mystery. Now comes a surprising twist, from the complete nuclear genome of a Siberian boy who died 24,000 years ago—the oldest complete genome of a modern human sequenced to date. His DNA shows close ties to those of today's Native Americans. Yet he apparently descended not from East Asians, but from people who had lived in Europe or western Asia. The finding suggests that about a third of the ancestry of today's Native Americans can be traced to "western Eurasia," with the other two-thirds coming from eastern Asia, according to a talk at a meeting* here by ancient DNA expert Eske Willerslev of the University of Copenhagen. It also implies that traces of European ancestry previously detected in modern Native Americans do not come solely from mixing with European colonists, as most scientists had assumed, but have much deeper roots. "I'm still processing that Native Americans are one-third European," says geneticist Connie Mulligan of the University of Florida in Gainesville. "It's jaw-dropping." At the very least, says geneticist Dennis O'Rourke of the University of Utah in Salt Lake City, "this is going to stimulate a lot of discussion."

What I find particularly interesting is that it sheds new light on the assumption that the European ancestry seen in Native Americans is solely the result of recent admixture.
