Actually, Piltdown Man threw a wrench into the works of investigating human evolution. In 1925, Raymond Dart found the Taung skull, a fossil in South Africa that he believed was the earliest human ancestor (now known as Australopithecus). But few people accepted his find; it didn't fit in with Piltdown, for one thing. It had a small brain, yet a human-like jaw. But mostly, it came from Africa, and many European scientists preferred to have England be the cradle of humanity. Dart was ultimately proved correct.
