Bone harpoons on the Semliki River show humans planned, fished, and taught
Around 90,000 B.C.E., people near the Semliki River in central Africa carved barbed harpoon heads from bone — the oldest confirmed tools of their kind. The site’s catfish bones suggest planned, seasonal expeditions. These aren’t just ancient artifacts; they’re evidence that cumulative human culture was already underway in Africa.
