Capuchin monkeys are well-known for their extensive manipulative prope
nsities which rival those of chimpanzees. This report examines the pro
duction and use of tools by capuchins with the aim of gaining insight
into the origins of hominid material culture. It is proposed that rese
arch examining tool-making and tool-using in extant nonhuman primates
can facilitate greater understanding of the mental life of Homo habili
s and other early hominid species.
