Homo habilis
Society

H. habilis coexisted with H. rudolfensis, H. ergaster / H. erectus, and P. boisei. It is unclear how all of these species interacted. To explain why P. boisei was associated with Olduwan tools despite not being the knapper (the one who made the tools), Leakey and colleagues, when describing H. habilis, suggested that one possibility was P. boisei was killed by H. habilis, perhaps as food. However, when describing P. boisei five years earlier, Louis Leakey said, "There is no reason whatever, in this case, to believe that the skull represents the victim of a cannibalistic feast by some hypothetical more advanced type of man."
