Scavenging explains many of the body traits that humans have.. are good binocular vision allows us to see long distances.. so prehistoric man may have been able to see buzzards surfing over a corpse miles away.. so then we began to ran toward the corpse but we had to run fast so that we could beat the other animals to it.. our skeletal structure allows us to run fast and the fact that we have little hair allows us to sweat and carry off the heat so we can run long distances quickly.. once we get to the corpse there are likely other animal scavenging it such as hyenas, and our ability to grasp rocks and throw them allowed us to throw rocks at the hyenas or whatever and scare them off the corpse.. then if there was even little meat left we could pick up a rock smash the bones and get the marrow out.. this explains how we got good long distance binocular vision, a skeleton that allows us to run, a body that allows us to carry off heat through sweating, hands and other anatomy that can grasp and throw stones, and smash bones to get the marrow out
