A finger fossil bone has shown that the Australopithecus afarensis did not have flat feet -- that is, they had a proper physiognomy to walk on both skates -- and did not live on trees. The bone has been studied by a team of paleontologists from the University of Missouri, a metatarsus of the fourth observation that, according to experts, has a very different bone for species adapted to life on the tree --flat bone - and for those who are adapted to walk on the curved floor bone. Paleontologists have found few fossil bones of the feet of the australopitheces, and it is the first time they find a fourth metatarsus. The famous fossil Lucy, for example, lacks feet, but other features of the skeleton have led him to believe he was walking on the ground and both legs. Now, the study of the metatarsus has reinforced this hypothesis.
