They know some of what happened but not why. One thought is that the forest area became deforested because of climate change. Causing the pre-humans to leave the trees and forced to stand upright by tall grass but this idea has becomed questioned lately. There is a slight hint that living by the sea or water shore caused changes in brain chemicals and in the throat. This, I assume, happened because of eating and diving for seafood. You have to keep reading up to date information.

Food was the primary need, then protection from predators and against the climate. I would say these three were the most important.
