"WASHINGTON - New evidence shows humans lived in North America more than 14,000 years ago, 1,000 years earlier than had previously been known.
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....
To make sure the Oregon cave material hadn't been contaminated with modern DNA, the researchers tested more than 50 people who worked at the site. The DNA testing indicated that the feces belonged to Native Americans in two groups that can be traced to Siberia and East Asia."
