When we were in the trees, and when we came down, I believe we differentiated ourselves based on our strength. Going down into the wild with things that can eat us required good strength, also intelligence. Otherwise, how would we survive? Evolutionary speaking, possibly random mutations first occurred with intelligence and/or strength, which made us more able to deal with that which was scary and below. Over time, this strength and conditioning with good intelligence, selection, and a development of culture surrounding this phenomena, over time emerged the humans.
Sometimes I go so far as to say that these prehumans were probably even doing a kind of pushup, acrobatics with their surroundings, and maybe even were good wrestlers, or tricky fighters.
This is my explanation as a person without an explanation. I have heard of punctuated equilibrium. I have even studied physical anthropology, and there is not much out there in traditional academia. Thus, this is what I think happened. What do you think?
