Turnover Pulse Vagueness

The turnover-pulse idea proposes, first, that global temperature fell
precipitously. Second, that this event caused the spread of arid
grasslands within the savanna patchwork of Africa. And, third, that
the growth of these grasslands prompted synchronized change in
hominids and other animal populations. The regional division of
populations led new species to arise, while the force of natural
selection caused new adaptations to evolve. The hominids were
converted to live in open terrain."


This is the best conventional theorists can do.
