Academics ‘pretty confident’ extinct hominid species could walk as well as climb trees 7m years ago
was said to have had “the impact of a small nuclear bomb” as it pushed back the ancestral line of hominids – the line leading toThe question as to whether the species walked upright remained unanswered.
“We can conclude from the evidence that we have habitual bipedalism, plus quadrupedal arborealism, which is what is observed for early hominids and then gradually turns into the obligate bipedalism inMore recent hominid fossils, including the“We are pretty confident,” said Franck Guy, also a co-author. “What we show is that the morphological pattern of the femur is more similar to what we know in humans, including fossil humans, than in apes.
Prof Bernard Wood, of George Washington University, who was a co-author of a previous study that concludedwas not habitually bipedal, said: “These critically important fossils deserve better treatment than this shoddy paper provides. The study cherrypicks evidence, ignores recent studies that point to different conclusions than the ones the authors try to defend, and it fails to explore other equally, if not more likely, functional interpretations of these fossils.
“All of the three bones resemble chimpanzees more closely than any other living great ape, including modern humans. That does not meanwas a chimpanzee, but it was likely closely related to chimpanzees, and its lifestyle was chimpanzee-like. It was not an upright, ground-living ape of the kind that were likely to have been our earliest ancestors.
