TL;DR: 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.

An Ecological Model of Female-Bonded Primate Groups
TL;DR: A model is presented to account for the evolution of FB groups in terms of ecological pressures on female relationships and suggests that relationships in most FB groups are ultimately related to feeding competition.

Why Are Diurnal Primates Living in Groups
TL;DR: A critical test is proposed of the hypothesis that increasing group size should lead to reduced predation risk by comparing demographic patterns between areas where predators are still present and where they have disappeared and the results provide strong support for the predation-feeding competition theory.
