New Mexicans weren't alone in the New World

Stone spearheads and human DNA found in Oregon caves, anthropologists say, have produced firmer evidence that these are the oldest directly dated remains of people in North America. They also show that at least two cultures with distinct technologies — not a single one, as had been supposed — shared the continent more than 13,000 years ago. In other words, the Clovis people, long known for their graceful fluted projectile points, were not alone in the New World. The occupants of Paisley Caves, on the east side of the Cascade Range, near the town of Paisley, left narrow-stemmed spear points shaped by different flaking techniques. These hunting implements are classified as the Western Stemmed Tradition, previously thought to be younger than the Clovis technology. The findings lend support to an emerging hypothesis that the Clovis technology, named for the town in New Mexico where the first specimens were discovered, actually arose in what is now the Southeastern United States and moved west to the Plains and the Southwest. The Western Stemmed technology began, perhaps earlier, in the West. Most artifacts of that kind have been found on the West Coast and in Idaho, Nevada, Utah and Wyoming...more
