Australopithecus afarensis was one of the longest-lived and best known early human species (reconstruction pictured). The species, whose most famous fossil 'Lucy' comes from Ethiopia, roamed the Earth around 3.2 million years ago - but recent evidence has suggested they were not alone
Australopithecus afarensis is an extinct hominid that lived between 3.9 and 2.9 million years ago. The most famous fossil is the partial skeleton named Lucy (3.2 million years old) found by Donald Johanson and colleagues.
A fossil of a 3.4 million-year-old hominin has been found by researchers who say this could be an entirely new species of early human, previously unknown to history. This new and distinct hominin is thought to have lived side by side with Australopithecus afarensis, commonly identified with the well-known skeleton Lucy, and was one of several diverse species of hominins living in the northern region of Ethiopia between 3.3 and 3.5 million years ago.
