Actually there was some Late Pleistocene megafaunal extinctions in
Africa, particularly in the southern part. However another important
factor about Africa is that being the urheim of humans it is also
the home of nearly all our parasites. This has kept the population
low and until modern medicine came in there were large areas that
were essentially uninhabitable to humans, for example through river
blindness (West Africa) or nagana (Central and Eastern Africa).

Hmm...are African animals harder for humans to hunt and more
dangerous towards them than species from other regions? This could
be rich territory for animal behavior research to explore.
