A fossilized foot bone recovered from Hadar, Ethiopia, shows that by 3.2 million years ago human ancestors walked bipedally with a modern human-like foot. These findings support the hypothesis that A. afarensis was primarily an upright walker, as opposed to a more versatile creature that also moved through the trees.
