Homo erectus is the first known early human that had a body very similar to that of modern humans. It had longer lower limbs than upper limbs, a torso shaped more like ours, and a larger cranial capacity than earlier hominids. In 1974, scientists in the East Turkana region of Kenya found one of the oldest pieces of evidence for H. erectus: a small skull fragment that dates to 1.9 million years. The specimen is surpassed in age only by a 2-million-year-old skull specimen in South Africa. But there was pushback, with some researchers arguing that the East Turkana specimen could have come from a younger fossil deposit and was possibly moved by water or wind to the spot where it was found.
