“…In this paper we present a new approach to modelling group coordination, based on dyadic synchronisation in a non-panmictic, structured network (a problem that applies widely to all species that live in medium to large groups). …”

Implications of body mass and predation for ape social system and biogeographical distribution by Lehmann, J, Dunbar, R

“…Despite the fact that all African great apes have overlapping diets, they differ substantially in both biogeographical distribution and social organisation: <em>Gorilla</em> lives in relatively small, cohesive groups within a small biogeographical area while <em>Pan</em> is much more widely distributed and lives in large, fluid groups in which the members are rarely all together. …”

To do this we construct a map of our evolving social complexity that concentrates on two resources - materials and emotions - that lie at the basis of all social interaction. …”
