Journal ArticleDOI
The Evolutionary Origins of Friendship
TL;DR: Convergent evidence from many species reveals the evolutionary origins of human friendship; females with the strongest, most enduring friendships experience less stress, higher infant survival, and live longer.
Journal ArticleDOI
The acquisition of rank and the development of reciprocal alliances among free-ranging immature baboons
TL;DR: A model is presented that attempts to explain ontogenetic changes in alliance formation on the basis of the potential costs and benefits of entering into aggressive alliances with particular indivuduals.
Journal ArticleDOI
How vervet monkeys perceive their grunts: Field playback experiments
TL;DR: This paper found that free-ranging vervet monkeys grunt to each other in a variety of social situations: when approaching a dominant or subordinate individual, when moving into a new area of their range, or when observing another group.
Journal ArticleDOI
Assessment of meaning and the detection of unreliable signals by vervet monkeys
TL;DR: This paper found that free-ranging vervet monkeys, Cercopithecus aethiops, who had learned to ignore playbacks of one type of call by an unreliable signaller subsequently also ignored playback of an acoustically different call by the same individual if the calls had similar referents.
Journal ArticleDOI
Nonrandom Dispersal in Free-Ranging Vervet Monkeys: Social and Genetic Consequences
TL;DR: While males seem to benefit by transferring nonrandomly with their peers when young, it may be more advantageous for older males to disperse alone, and age-related changes in the social benefits of nonrandom transfer appear to have important genetic consequences for the population as a whole.
