Social Relationships, Social Cognition, and the Evolution of Mind in Primates
During the past 20 years, research on cognition in primates and other animals has shifted from the laboratory to the field—from studies of animals' knowledge of objects to research on what they know about each other. Primates and many other animals live in rich, complex societies where animals form highly differentiated relationships and selection has favored the formation of enduring, long-term bonds. As a result, the social environment is chara…
The Evolutionary Origins of Friendship
Convergent evidence from many species reveals the evolutionary origins of human friendship. In horses, elephants, hyenas, dolphins, monkeys, and chimpanzees, some individuals form friendships that last for years. Bonds occur among females, among males, or between males and females. Genetic relatedness affects friendships. In species where males disperse, friendships are more likely among females. If females disperse, friendships are more likely a…
Primate social cognition as a precursor to language
"In The Oxford Handbook of Language Evolution, sixty leading scholars present critical accounts of every aspect of the field. Its five parts are devoted to insights from comparative animal behavior; the biology of language evolution (anatomy, genetics, and neurology); the prehistory of language (when and why did language evolve?); the development of a linguistic species; and language creation, transmission, and change. Research on language evolut…

Age- and Sex-Related Variations in Clear Calls of Papio ursinus
Constraints and preadaptations in the earliest stages of language evolution
If we accept the view that language first evolved from the conceptual structure of our pre-linguistic ancestors, several questions arise, including: What kind of structure? Concepts about what? Here we review research on the vocal communication and cognition of nonhuman primates, focusing on results that may be relevant to the earliest stages of language evolution. From these data we conclude, first, that nonhuman primates’ inability to represent…
Contextual Factors Meditating Contests Between Male Chacma Baboons in Botswana: Effects of Food, Friends and Females
The adaptive value of ‘friendships’ to female baboons: Experimental and observational evidence
Lactating female baboons, Papio cynocephalusoften maintain close associations with particular males. There are at least three proposed benefits of 'friendships' to females: (1) male protection against potentially infanticidal males; (2) male protection against harassment by dominant females; (3) male attachment to an infant that develops into future care of juveniles. These hypotheses were examined in a population of chacma baboons, P. c. ursinus…
The acoustic features of gorilla double grunts and their relation to behavior
Mountain gorillas ( Gorilla gorilla beringei ) give double‐grunts to one another in a variety of situations, when feeding, resting, moving, or engaged in other kinds of social behavior. Some double‐grunts elicit double‐grunts in reply whereas others do not. Double‐grunts are individually distinctive, and high‐ranking animals give double‐grunts at higher rates than others. There was no evidence, however, that the probability of eliciting a reply d…
Group fusions and minimum group sizes in vervet monkeys ( Cercopithecus aethiops )
Six unequivocal cases of group fusion occurred between 1984 and 1988 in a declining population of vervet monkeys ( Cercopithecus aethiops ) in Amboseli National Park, Kenya. In each case, the remaining group members abandoned their territory and joined a neighboring group shortly after the group lost its penultimate adult. Because the number of juveniles did not appear to influence the timing of fusion, only adults (both males and females) appear…

Group extinction and fusion in free‐ranging vervet monkeys
Three cases of group fusion were observed among vervet monkeys in Amboseli National Park, Kenya, during the 1984 drought. In all cases, group fusion involved the migration of at least two females into a small neighboring group. Following migration, the females' natal groups ceased to exist. Although migrants initially assumed low ranks, none received high rates of aggression, and two rose in rank 6 months after their arrival. Migrant females appe…
Grooming, alliances and reciprocal altruism in vervet monkeys
Nonrandom Dispersal in Free-Ranging Vervet Monkeys: Social and Genetic Consequences
Male vervet monkeys in Amboseli National Park, Kenya, disperse nonrandomly from their natal groups at sexual maturity, and migrate to specific neighboring groups with their brothers or peers. Nonrandom dispersal in the company of allies appears to benefit young males by minimizing the risk of predation and reducing the probability of attack by resident males and females. Nonrandom dispersal also decreases the likelihood of mating with close femal…
Monkey Responses to Three Different Alarm Calls: Evidence of Predator Classification and Semantic Communication
Vervet monkeys give different alarm calls to different predators. Recordings of the alarms played back when predators were absent caused the monkeys to run into trees for leopard alarms, look up for eagle alarms, and look down for snake alarms. Adults call primarily to leopards, martial eagles, and pythons, but infants give leopard alarms to various mammals, eagle alarms to many birds, and snake alarms to various snakelike objects. Predator class…
