In the sweltering heart of Senegal, in a place called Fongoli, a chimpanzee performs an earth-shattering act: she strips a branch of its leaves, chews the tip into a point, and jams the tool into a hole in a tree, killing a bushbaby. In short, she has been spear-hunting -- making tools and using them to hunt. Only humans are supposed to be capable of that. And Fongoli's scrubby mixture of woodland and savanna may mirror the ancient place where we may have taken our first steps - literally - towards being human. Are the chimps of Fongoli giving us a window into the lives of our earliest ancestors?
