Fission‐Fusion Dynamics
Renewed interest in fission‐fusion dynamics is due to the recognition that such dynamics may create unique challenges for social interaction and distinctive selective pressures acting on underlyingExpand

Conflict resolution following aggression in gregarious animals: a predictive framework
Knowledge of how animals manage their conflicts is critical for understanding the dynamics of social systems. During the last two decades research on gregarious animals, especially primates, hasExpand

Energetics and the evolution of human brain size
The human brain stands out among mammals by being unusually large. The expensive-tissue hypothesis explains its evolution by proposing a trade-off between the size of the brain and that of theExpand

THE EVOLUTION OF MONOGAMY IN LARGE PRIMATES: A NEW HYPOTHESIS AND SOME CRUCIAL TESTS
Monogamy among the large primates is not accompanied by high levels of male care for infants. The selective pressures that have led to its evolution in this case are far from clear. In this paper, weExpand

Orangutan activity budgets and diet: A comparison between species, populations and habitats
The chapter examines differences in the activity budgets of wild orangutans (Pongo spp.) within and between a large number of study sites in Sumatra and Borneo. The authors of the chapter found thatExpand

Cooperative breeding and human cognitive evolution
Despite sharing a recent common ancestor, humans are surprisingly different from other great apes. The most obvious discontinuities are related to our cognitive abilities, including language, but weExpand

Cyclicity in the structure of female baboon social networks
There is an established and very influential view that primate societies have identifiable, persistent social organizations. It assumes that association patterns reflect long-term strategic interestsExpand
