We found evidence for a big evolutionary jump between the kind of hand represented by Ardi and all later hominin hands, including that of Lucys species, Dr. Prang said. This suggests that Ardi did not walk on her knuckles and only used her palms to move along tree branches. [9]:67[clarification needed], Although it is not yet clear how Ardi's species is related to Homo sapiens, the discovery is of great significance and added much to the debate on Ardipithecus and its place in human evolution.

Although considered to be one of the most primitive hominids, Ar. We found evidence for a big evolutionary jump between the kind of hand represented by Ardi and all later hominin hands, including that of Lucys species, Dr. Prang said. This suggests that Ardi did not walk on her knuckles and only used her palms to move along tree branches. [9]:67[clarification needed], Although it is not yet clear how Ardi's species is related to Homo sapiens, the discovery is of great significance and added much to the debate on Ardipithecus and its place in human evolution. [14] This opposable hallux is believed to have been used to aid in tree climbing. Peddlers Daughter Owner,
