EVOLUTION UNDER WAY  ~4 million years

Australopithecus anamensis is a fossil species of Australopithecus. He is thought to have lived from 4.1 and 3.9 million years ago. The older specimens were found between two layers of volcanic ash, dated to 4.17 and 4.12 million years, coincidentally when A. afarensis appears in the fossil record.

Australopithecus afarensis is an extinct hominid which lived between 3.9 and 2.9 million years ago. A. afarensis was slenderly built, like the younger Australopithecus africanus. It is thought that A. afarensis was ancestral to both the genus Australopithecus and the genus Homo, which includes the modern human species, Homo sapiens. The most famous fossil is the partial skeleton named Lucy by Donald Johanson and colleagues, after they played the Beatles song Lucy in the Sky with Diamonds over and over in celebration of their find.
