Australopithecus afarensis is an extinct species of australopithecine which lived ... A. afarensis was also capable of bipedal running with absolute speeds of 1.74 ...
Australopithecus afarensis model at the Smithsonian National Museum of Natural History. This reconstruction depicts the facultative bipedalism hypothesis, indicated by the use of the tree for stabilization.
The foot and other evidence from the lower limb provide clear evidence for bipedal locomotion, but the gorilla-like scapula and long and curved manual phalanges raise new questions about the importance of arboreal behaviour in the A. afarensis. DIK-1-1 skeleton; notice the diverging left big toe bone
The discovery of these footprints settled the issue, proving that the Laetoli hominins were fully bipedal long before the evolution of the modern human brain, and were bipedal close to a million years before the earliest known stone tools were made. [11] The footprints were classified as possibly belonging to Australopithecus afarensis.
Lucy’s discovery transformed our understanding of human origins. Don Johanson, who unearthed the Australopithecus afarensis remains in 1974, recalls the moment he found the iconic fossil.

A new analysis of three-toed fossil footprints that date back more than 210 million years reveals that they were created by bipedal reptiles with feet like a bird’s.
Members of Australopithecus are sometimes referred to as the "gracile australopithecines", while Paranthropus are called the "robust australopithecines". [ 10 ] [ 11 ] The australopithecines occurred in the Late Miocene sub-epoch and were bipedal , and they were dentally similar to humans, but with a brain size not much larger than that of ...
