Discovered in a cave in Oregon, fossil feces yielded DNA indicating these early residents were related to people living in Siberia and East Asia, according to a report in Thursday's online edition of the journal Science.
"This is the first time we have been able to get dates that are undeniably human, and they are 1,000 years before Clovis," said Dennis L. Jenkins, a University of Oregon archaeologist, referring to the Clovis culture, well known for its unique spear-points that have been studied previously.
Humans are widely believed to have arrived in North America from Asia over a land-bridge between Alaska and Siberia during a warmer period. A variety of dates has been proposed and some are in dispute.
