During the Miocene Africa began to shift from a warm, moist climate to
a warm drier climate and began to take on the characteristics we find
there today. At about this time there was an adaptive radiation of
apes. It is not so much a question of being driven out as an expansion
to fill new ecological niches. The savanna niche was expanding right
about the time we think the hominid/pongid common ancestor and its
immediate descendents were around.
Because of a more effective heat rejection system, hominids were able
to forage on the savanna at a time when most predators were seeking
shade to avoid overheating.
At least, that is one possible explanation.
I see you are a fellow SUNY student. Anthropology?
