Abstract
Abstract Research with captive capuchin monkeys has demonstrated that these New World primates produce flaked stone artifacts that they use as cutting tools, and that they exhibit patterns of right‐handedness analogous to those of tool‐making Plio‐Pleistocene hominids. These findings indicate that the cognitive and biomechanical conditions of pre‐adaptation for the production and use of stone tools are present in extant nonhuman primates, and that capuchins can be used to model processes associated with the evolution of technology and symbolic communication in humans.
