If you trace your ancestors back far enough, about ten million years ago they were gorillas. Then came chimpanzees and so in until here you are. Wiki has a page on Olduvai Gorge in Tanzania, Africa. It mentions the first use of tools, made from rocks from which sharp edged chips were knocked off which were used as knives. Olduvai gorge sort of funnels the migrating animals coming through the gorge from up north. They were easy targets so the Olduvai people got meat and thrived. Some migrated north until they left Africa but the story begins in Africa. No better story has appeared so there it begins. In a gorge… Gorillas..
