AAAS: "Deadly sharp points found in Idaho could be the first American-made tools" Projectile tips dated to nearly 16,000 yrs ago meant to be hafted onto a wooden shaft might represent the oldest evidence of the first tool technology brought to the Americas. The site on the Salmon river has been inhabited for thousands of yrs, is called Nipéhe, for an ancient village there. In English, it became known as Cooper’s Ferry. Sixteen thousand yrs ago the river sat in an ice-free corridor set in a glacial amphitheater left by a retreating glacial episode. The overland route from the Bering Strait would have been blocked by massive ice, but the early explorers could have boated south + turned left into the Columbia River. "The rough-and-ready stemmed projectile points, made from whatever rocks were on hand, differ significantly from so-called Clovis points." Knapped from better quality stone, Clovis points came to dominate the continent's toolmaking landscape about 13,000 yrs ago. There is a possible relationship between 'stemmed points' in Idaho + those crafted by people near modern-day Hokkaido, Japan some 20,000 yrs ago. Similar work on Cedros Island off the coast of Baja California describes 11,500-yr-old fishhooks made from shells that 'appear strikingly similar to 23,000-year-old shell fishhooks from Okinawa, Japan.'  Not certain if convergent innovations or direct lineal descendents. #archeology #spearpoints
