Oldest Human Remains Found in North America

Some really old sh&t shoots Clovis origin theory and ice-free corridor supporters.

Popular Science:
Native Americans living in Oregon thousands of years ago did what came naturally before the advent of flush toilets (or the state of Oregon): They relieved themselves in a lakeside cave. Thanks to them, scientists now have samples of the oldest human DNA ever found in the New World.

The ancient coprolites (dried excrement) left behind by these early Americans remained in place until 2002, when University of Oregon archaeologist Dennis Jenkins and colleagues began finding them during summer field work at Oregon's Paisley Caves. A team at Denmark's Centre for Ancient Genetics has since studied the coprolites, and today published its analysis of DNA recovered from six of the specimens.

Radiocarbon dating done on the coprolites found that some of them date back as far as 14,300 years ago. That is 1,200 years older than the Clovis culture, long associated with the earliest Americans. Other sites believed to represent pre-Clovis habitation have been investigated, but intact human DNA has never been recovered from any of them.
The LA Times has a more comprehensive story.
