RE: Primate news
New research on Twa Pygmies of Uganda in Africa has shed light on the evolution of our feet. The Twa are able to climb trees just as well as chimpanzees. This is because the unusually long muscles of their calves provides extra flexibility to their ankles, which can bend up to a 45 degree angle (the same as chimps). The length of the calf muscles is the result of practice not mutation. The muscles stretch over the course of their lives. This discovery has helped anthropologists understand why the Australopithecines (southern apes) had human feet but had long ape-like arms, shoulder blades, and curved fingers. Scholars can't say for certain whether they climbed trees regularly, but nothing about their (our) foot design would hinder this ability.
