Abstract

Explaining the evolution of altruistic behaviours is key to understand the complex social organisation of animals in general, and especially of primates. Several hypotheses have been proposed but much confusion still exists in the literature. In particular, a gap can be found between theoretical approaches to the study of the evolution of altruism and empirical studies and observations of actual altruistic behaviours. Our study focuses on altruistic behaviours of common marmosets (Callithrix jacchus), such as grooming and feeding tolerance, adopting a cross-methodological approach: first, we collect observational data on the behaviour of marmosets living in captivity; second, we use agent-based modelling (ABM) to study evolutionary mechanisms and inter-individuals dynamics of reciprocal exchanges. Finally, we compare the results obtained by ABMs with those resulting from the observations with the aim of trying to understand the extent to which the assumptions underlying our theoretical models match with the actual behaviour of primates.
