An analysis of wrist anatomy in humans, chimps, bonobos and gorillas indicates our own bipedalism probably did not evolve from a knuckle-walking ancestor. "Our data support the opposite notion, that features of the hand and wrist found in the human fossil record that have traditionally been treated as indicators of knuckle-walking behavior in general are in fact evidence of arboreality," researchers report.
