Today it was announced that scientists had unearthed in Ethiopia the first nearly complete skull of the earliest recognized human ancestors. It's that of a male who lived three million years ago, giving a face to the species first identified in 1974 with the discovery of the skeleton named "Lucy." Paleoanthropologist Donald Johanson discovered Lucy and was part of the team to make this new discovery. The discovery could settle the debate of whether various fossils from this time period were from a single species, Australopithecus afarensis, or from different species.
