Fossils found in Africa provide important evidence about human evolution. Fossils show that the earliest human-like creatures lived in Africa 3 million years ago, including "Lucy" who was an early hominid. Even older fossils have been found, such as "Tumai" dated to over 3 million years old. Fossils help scientists learn about the development of hominids into upright, tool-making, fire-using humans over millions of years, eventually resulting in modern Homo sapiens.
