Australopithecus afarensis arm bones were strong relative to leg bones; walking gait was likely inefficient.
PLOS—Scans of bones from "Lucy," the 3.18 million-year-old Australopithecus afarensis fossil, suggest that the relative strength of her arms and legs was in between that of modern chimpanzees and modern humans, according to a study published November 30, 2016 in the open-access journal PLOS ONE by Christopher Ruff from Johns Hopkins University School of Medicine, USA, and colleagues.
