The document discusses early humans in Africa based on fossil evidence. It describes Lucy, a 3 foot 8 inch tall female skeleton from Australopithecus afarensis that was discovered in Ethiopia in 1974. Early Africans are believed to have lived by gathering plants and scavenging meat around 1.9 million years ago. The document also notes that genetic evidence shows Africa was the only place modern humans lived until around 60,000 years ago. It poses questions about how early Africans related to each other and what caused the extinction of A. afarensis.
