This find sheds light on the movement of these early hominids. Lucy was believed to be a tree climber and she was not believed to be bipedal. But this discovery shows that it is likely that early hominids were bipedal. This skeleton has the most complete clavicle and shoulder blades ever found in the human fossil record.
