Sequence and Environments of the Lower and Middle Miocene Hominoids of Western Kenya
A widespread hypothesis in anthropological science is that at some stage in the evolution of humans there must have been an adaptive shift from an arboreal forest existence to a terrestrial savannah one. The reasoning behind this idea seems to be that most extant apes are forest-dwelling, leading to the conclusion that this is probably the primitive (plesiomorphic) hominoid adaptation. Humans, in contrast, are adapted to savannah settings, and this represents a highly derived (apomorphic) condition among hominoids.
