A central issue in the evolution of social complexity and the evolution of communication concerns the capacity to communicate about increasingly abstract objects and concepts. Many animals can communicate about immediate behavior, but to date, none have been reported to communicate about behavior during future interactions. In this study, we show that a special, unidirectional, cost-free dominance-related signal used by monkeys (pigtailed macaques: Macaca nemestrina) means submission (immediate behavior) or subordination (pattern of behavior) depending on the context of usage. We hypothesize that to decrease receiver uncertainty that the signal object is subordination, senders shift contextual usage from the conflict context, where the signal evolved, to a peaceful one, in which submission is unwarranted. We predict and find that deceasing receiver uncertainty through peaceful signal exchange facilitates the development of higher quality social relationships: Individuals exchanging the peaceful variant groom and reconcile more frequently and fight less frequently than individuals exchanging signals only in the conflict context or no signals. We rule out alternative hypotheses, including an underlying reciprocity rule, temperament, and proximity effects. Our results suggest that primates can communicate about behavioral patterns when these concern relationship rules. The invention of signals decreasing uncertainty about relationship state is likely to have been critical for the evolution of social complexity and to the emergence of robust power structures that feed down to influence rapidly changing individual behavior.cost-free signal ͉ social complexity ͉ subordination ͉ uncertaintyreduction ͉ innovation

“…Tool using was once believed to be a characteristic unique to humans, but there is increasing evidence of tool using by other species, including nonhuman primates, elephants and birds (Goodall, 1964; Beck, 1980; Rogers and Kaplan, 1993;Chevalier-Skolnikoff and Liska, 1993;Petit and Thierry, 1993; Nishida and Nakamura, 1993;Tokida et al 1994;Hunt, 1996). However, the capuchins are the only New World species so far reported to use tools.…”

Studies of hand preferences in the platyrrhine species are reviewed. Hand preferences of the New World species have been recorded during feeding activities, visuospatial reaching, haptic discrimination, tool use and in a variety of routine tasks using the hands.Of the New World species tested so far, the common marmoset (Callithrix jacchiis) and squirrel monkeys {Saimiri sciureus), appear to be the only species that do not display handedness in feeding activities: at the population level both species display a symmetrical distribution of hand preferences. It appears that only one New World primate species, the spider monkey (Ateles geoffroyi), displays left handedness during feeding while the other species are right handed or have no handedness. Thus, tlie findings for hand use in feeding do not support the Postural Origins hypothesis of MacNeilage et al. (1987) as it predicts left handedness rather than right in the arboreal platyrrhine species.Overall, tlie reports of handedness for tasks requiring complex visuospatial or tactile processing in the New World primates concur with those reported for humans, who have left handedness in haptic discrimination and complex visuospatial tasks and right handedness for manipulative tasks. Squirrel monkeys are left handed when reaching for moving objects and capuchins display left handedness in haptic discrimination tasks, and right handedness during sponging tasks.There is strong evidence of an effect of posture on the strength of hand preferences, and some affects of age and gender on hand use have also been reported. However, these variables do not influence hand preferences consistently across species or across tasks conducted with the same species.
