Moreover, the foot, vertebra and pelvis fossils give a lot of information to understand more about bipedalism in early hominids. A small feature with big implications was found on the ardipithecus pelvis and it is clear evidence that ardipithecus walked up right. ARDI’s remains help understand evolution better because the fossils are the oldest ever found, and they show characteristics that are not found in other fossils. ARDI’s fossils also answer a lot of questions that Lucy could not answer. AA The structure of the feet is like nothing else seen before. It is the feet of a bipedal hominid but the founding of the medial cuneiform bone tells us that ARDI had grasping feet. ARDI was not like a human or a modern chimpanzee, ARDI was an evolutionary mosaic with different traits that were lost and gave way to the...
