World's Oldest Stone Tools Discovered In Kenya

sciencehabit writes: Researchers say they have found the oldest tools made by human ancestors—stone flakes dated to 3.3 million years ago. That's 700,000 years older than the oldest-known tools to date, suggesting that our ancestors were crafting tools several hundred thousand years before our genus Homo arrived on the scene. If correct, the new evidence could confirm disputed claims for very early tool use, and it suggests that ancient australopithecines like the famed 'Lucy' may have fashioned stone.

      As others have pointed out, this is false. Multiple species kill for fun.

      War is mate competition pursued by other means. The reasons why humans kill each other is because it is an evolved, adaptive, behaviour carried over into a world that we are desperately trying to engineer in such a way that killing is no longer necessary or functional. The problem is that it's still fun: it feels good because we are the descendents of individuals who were selected to be good at it, and part of being good at it was enjoying it, getting an immediate, internal, biochemical reward for behaviour that was also adaptive (that produced more offspring).

      As such, sports and other forms of competition that allow us to activate that in-built reward system without actually killing people are really important to keeping human society reasonably peaceful.
