Around 500,000 years ago, hunters in southern Africa began attaching shaped stone points to wooden shafts — creating the earliest known composite weapon. Evidence from Kathu Pan 1 pushes the record back 200,000 years. It is a milestone in human planning, teaching, and the long story of minds building tools together.
Around 200,000 B.C.E., Neanderthals at a site in what is now central Italy heated birch bark to produce tar — and used it to bind stone tools to wooden handles. The evidence challenges long-held assumptions about Neanderthal intelligence and marks one of the earliest known acts of deliberate chemical transformation in human history.
