Abstract
We observed grips by the hand during locomotor and manipulative behavior of captive chimpanzees to improve our ability to interpret differences between chimpanzees and humans in hand morphology that are not easily explained by current behavioral data. The study generated a new classification of grips,which takes into account three elements of precision and power gripping that appear to distinguish between the chimpanzees and humans, and which have not been explored previously in relation to hand morphology. These elements are (1) the relative force of the precision grips (pinch versus hold), (2) the relative ability to translate and rotate objects by the thumb and fingers (precision handling), and (3) the relative ability to orient a cylindrical object so that it functions effectively as an extension of the forearm (power squeeze). We recommend that this classification be incorporated into protocols for field and laboratory studies of nonhuman primate manipulative behavior, in order to test our prediction that these three elements clearly distinguish humans from chimpanzees and other nonhuman primates. The results of this test will have direct bearing upon decisions as to which grips (with their associated behaviors) are most likely to guide us through kinematic and kinetic analysis to possible explanations for morphological differences between humans and other species. These explanations, in turn, are fundamental to our ability to discern evidence for potential grips and tool behaviors in the manual morphology of fossil hominids.
