Stone-Tipped Spears Pre-date the Human Race -via Andy Cobley

Spears feel very much like a human weapon of war—so it's surprising to find out that, in fact, the stone-tipped projectiles pre-date our species by a bewildering 85,000 years.

A team of archaeologists from University of California at Berkeley have uncovered remains of the oldest known stone-tipped throwing spears, and their analysis suggests they're 280,000 years old. They were found at an Ethiopian Stone Age site known as Gademotta, and are reported in PLoS One.

But that age means that they're far older than Homo sapiens—which either suggests we're wrong about how long our race has existed, or that our predecessor species were smart enough to make weapons. Yonatan Sahle, one of the researchers, explains:

The First Spears

Analysis of 210 stone tools from the site of Kathu Pan in South Africa shows that people were probably hunting with stone-tipped spears by about 460,000 years ago, roughly 200,000 years earlier than previously believed. The study, led by University of Toronto doctoral candidate Jayne Wilkins, confirmed that the tools had broken in ways similar to other stone spear points that have been thrust or thrown into the bodies of animals. In addition, 23 of the tools appear to have been thinned at their bases to make them easier to attach to the shaft of a spear. To test their interpretation, the team made 32 replicas of the tools from Kathu Pan, hafted them to wooden dowels, and fired them into springbok carcasses using a crossbow that allowed for precise control of force. The replica spear points were damaged in ways similar to their ancient counterparts. The early date for the tools also suggests that the first stone-tipped spears were used by Homo heidelbergensis, the species of human that was the ancestor of both Neanderthals and modern humans.
