Final answer:

Australopithecus afarensis, a species of Australopithecus, lived between 3.9 and 2.9 million years ago. It had characteristics similar to apes and humans and moved bipedally with some differences.

Step-by-step explanation:

Australopithecus afarensis, a species of Australopithecus, lived between 3.9 and 2.9 million years ago. It had smaller canines and molars compared to apes, but they were larger than those of modern humans. A. afarensis had a brain size similar to that of a modern chimpanzee and possessed a relatively longer jaw. The shape of its pelvis suggests it moved bipedally, although with some differences compared to modern humans.
