BAR 1002'00

Beginning to walking upright on short legs

The upper part of this femur (thigh bone) is similar in size to those of other large apes. But the angled part more closely resembles that of modern humans. It formed a strong bridge with the hip to support the body’s weight, suggesting Orrorin tugenensis walked upright.
