Re: knuckle-walking.

Simons in Primate Evolution, MacMillan, 1972, p 236, indicates
knuckle-walking "is easily derived from arboreal quadrupedalism where both
wrist and elbow joints have developed locking flanges on certain joints,
together with robust phalanges adapted to supporting the compressive
forces produced by the weight of a comparatively larger forebody." The
Miocene ancestors of the modern African apes were rather gracial, even in
those forms with limb lengths comparable with modern chimpanzees.
