The metatarsal bone from Australopithecus afarensis — the species made famous by the 1974 discovery of the specimen known as Lucy — clearly shows that the species had stiff, arched feet just like modern humans.

- How out of touch am I with online technology? I just now discovered Groove Shark. Outstanding audio quality with the right headset.
