Stone tools offer new evidence of separate ancient Americans

This University of Oregon photo shows three Western Stemmed Projectiles discovered in the Paisley Caves near Paisley, Ore. Stone tools and human DNA from the ancient Oregon caves offer new evidence of how the first Americans spread through the continent- and archaeologists reported Thursday that they have dated broken spear points from the cave to about 13,200 years ago, as old as much different stone tools found elsewhere from the better-known Clovis culture found in the southeast and interior United States.
