The Big Thing That Advances Proto Humans Beyond Their Initial Animal State

For the materialist historian, the big thing that advances proto humans beyond their initial animal state is not that they had big brains, but instead that they decided to adopt bi pedal locomotion. The other big things humans have going for them is co operative labor. We always find humans working in groups together. So those early modern and enlightenment era depictions of man as a solitary creature in the state of nature are all wrong. Humans were never solit creatures. We are always in groups.
