I am curious:

Was a case of man walking out of the forests onto the Savannah,
or the forests evolving into Savannah as the climate changed?

Did the Savannah then evolve into desert and if so, would the
changes have begun near the center of a continent and spread
toward the edges, eventually forcing man into the sea?

Wouldn't these climatic changes have fluctuated back and forth
repeatedly over the last several million years, eventually
forcing man to adapt to a form which could handle different
enviornments as required?
