The social brain hypothesis
Conventional wisdom over the past 160 years in the cognitive and neurosciences has assumed that brains evolved to process factual information about the world. Most attention has therefore beenExpand
Coevolution of neocortical size, group size and language in humans
Group size is a function of relative neocortical volume in nonhuman primates. Extrapolation from this regression equation yields a predicted group size for modern humans very similar to that ofExpand
Neocortex size as a constraint on group size in primates
It appears that, among primates, large groups are created by welding together sets of smaller grooming cliques, and species will only be able to invade habitats that require larger groups than their current limit if they evolve larger neocortices. Expand
Grooming, Gossip and the Evolution of Language
Arguing that gossiping is vital to a society, and that there is no such thing as "idle" gossip, this book disputes the assumption that language developed in male-male relationships. The authorExpand
Gossip in Evolutionary Perspective
Conversation is a uniquely human phenomenon. Analyses of freely forming conversations indicate that approximately two thirds of conversation time is devoted to social topics, most of which can beExpand
Evolution in the Social Brain
It is suggested that it may have been the particular demands of the more intense forms of pairbonding that was the critical factor that triggered this evolutionary development. Expand
The Social Brain: Mind, Language, and Society in Evolutionary Perspective
▪ Abstract The social brain (or Machiavellian Intelligence) hypothesis was proposed to explain primates' unusually large brains: It argues that the cognitive demands of living in complexly bondedExpand
Primate social systems
This chapter discusses Primates and their Societies, social Evolution in Baboons, and Social Evolution in the Great Apes, as well as models as Descriptive Tools and Models as Analytical Tools, and the problem of Monogamy. Expand
Social network size in humans
Analysis of social network size in contemporary Western society based on the exchange of Christmas cards suggests that there may be cognitive constraints on network size. Expand
Primate Conservation Biology
This work integrates theoretical advances with practical management priorities to give scientists and policymakers the tools they need to help keep these species from disappearing forever. Expand
