Anthropologists have found starting evidence of

early human life in East Africa. In 1999 Mary and Louis Leaky found pieces of bone embedded in ancient rock at Olduvai Gorge in Tanzania. After careful testing, they concluded that the bone belonged to early hominids or  humanlike primate. In 1974 Donald Johanson  found part of hominid, the skeleton in Ethiopia. Johanson named his find Lucy  after a Beatle song.
