From the late 1930s, Louis and Mary Leakey found stone tools in the Olduvai Gorge and elsewhere, found several extinct vertebrates, including the 25-million-year-old Pronconsul primate, one of the first and few fossil ape skulls to be found. Their work at Olduvai Gorge had been interrupted by political uprisings in nearby Kenya, but late in the 1950s, they returned. The Leakeys were interested in prehistoric tools, but more and more wanted to find evidence of the people who made them. In 1959, they did.
