Deadly sharp points found in Idaho could be first American-made tools

Lethally sharp projectile points found along the banks of a river in southwestern Idaho, dated to nearly 16,000 years ago according to a study published today, could represent the oldest evidence of the first tool technology brought to the Americas.

Apparently deposited into a series of shallow pits by an ancient group of hunter-gatherers, the points are examples of “stemmed point technology,” which allowed people back then to fashion spear tips from a wide range of available materials. Based on the objects’ similarities to earlier artifacts, their discovers argue, the blueprint for making them may have come from East Asia.
