The disease costs of sociality have largely been understood through the link between group size and transmission. However, infectious disease spread is driven primarily by the social organization of interactions in a group and not its size. We used statistical models to review the social network organization of 47 species, including mammals, birds, reptiles, fish and insects by categorizing eac...

The social brain hypothesis (an explanation for the evolution of brain size in primates) predicts that humans typically cannot maintain more than 150 relationships at any one time. The constraint is partly cognitive (ultimately determined by some aspect of brain volume) and partly one of time. Friendships (but not necessarily kin relationships) are maintained by investing time in them, and fail...

The social brain hypothesis explains the evolution and function of social cognitive abilities in terms of maintaining extensive social relationships. To extend those findings we explored the role that social emotional abilities play in human sociality, and investigated how empathic abilities shape the social network. In line with the social brain hypothesis the findings show that dispositional ...
