As long as this thread has strayed this far I have had a gnawing question to present. Did the Homo skeleton evolve/mutate a more bipedal structure out of Homo's need to walk upright? Or did bipedalism occur because the Homo skeleton had evolved/mutated in a way that facilitated Homo walking upright? i.e. did Humans find out one day that their "new" body shape allowed them to run on two legs and have their hands free for weapons? It's easy to say that early Humans were bipedal, it's another to say early Humans force bipedalism into subsequent generations of skeletal evolution. Simply put, which came first, the need to walk upright? Or the Human skeleton's ability to allow bipedalism to become ubiquitous in all Human branches? Because bipedalism as a main means of efficient locomotion required a bone frame that would more easily facilitate that mode of travel. So, chicken? Or the egg?
