Known early range of *Australopithecus afarensis*

Human evolution & hominins · Australopitecos · Diversidad de homininos · Locomoción en mosaico

*Australopithecus afarensis* is documented in Ethiopia, Kenya, and Tanzania roughly 3.85–2.95 million years ago, so it overlaps with other hominin forms and varied environments. Its fossils include traits compatible with both terrestrial bipedal walking and climbing. Its relative abundance of remains does not make the species a single “link” or demonstrate that it was the direct ancestor of all later hominins.
