Of course it is theoretically possible that knuckle-walking did evolve only once in the common ancestor of the African ape and human clade and that these differences evolved after the Gorilla and Pan lineages split (Kivell & Schmitt 2009). The broad consensus that there is a clear lack of any convincing fossil evidence for knuckle-walking in crown hominoids or early hominins, however, would render it unlikely.>[...]>Despite the longevity of the paradigm that derived human bipedalism from chimpanzeelike knuckle-walking, we conclude that the arboreal origin of bipedalism is now overwhelmingly supported by the fossil, biomechanical and ecological evidence. The 50-year reign of the knuckle-walking paradigm must be declared over.»another retarded myth shattered beyond any doubt
>The purpose of being bipedal is because you use 50% less energry stalking and running down pray.wrong
arboreal bipedalism evolved because it allows you to more efficiently move around in the trees and reach more fruit, and humans retained it because it allowed for us to more efficiently walk long distances in search for the best fruit trees every day, which meant far more fresh and fully ripe fruits where other apes would have had to settle for less
