The australopithecines took advantage of these new conditions.By 3 million years ago, they were common in both East and South Africa.Some have been found dating to this period in North Central Africa also.It is likely that all of the early hominins, including humans, supplemented their diets with protein and fat rich termites and ants just as some chimpanzees do today.

In his 1871 book entitled The Descent of Man, and Selection in Relation to Sex, Charles Darwin speculated that fossils of the earliest humans and their immediate progenitors ultimately would be found somewhere in Africa.Few researchers were willing to estimate the time period of the earliest hominins at much more than 100,000 years, and there was no inkling of anything older from Africa.
