Symposium: The Development and Mechanisms Underlying Inter-individual Variation in Pro-social Behavior

Animals spend a high proportion of their time interacting cooperatively with conspecifics. This ranges from courtship, mating, and parental care behaviors to the complex coordinated behavior among related or unrelated individuals in group-living species. The evolutionary causes and consequences of such cooperative behavior have been a focus of biological research for nearly two centuries. A number of theoretical models such as those based upon reciprocity or kin selection predict the conditions under which cooperation is likely to evolve through natural selection. Although these models have resulted in productive research paradigms that have shaped the formal study of animal behavior for >50 years, recent models suggest that the evolution of cooperation is also heavily influenced by the degree of individual-variation in cooperative behavior as well as their underlying developmental and proximate mechanisms. Individual variation in cooperative behavior and the mechanisms underlying it are understudied by empiricists, despite their potential importance for the evolution of cooperation and social organization. The goal of our symposium is to produce a road map to study the developmental and proximate mechanisms in generating individual variation in cooperative behavior. Thus, we aim to establish new research avenues to study variation in cooperation using both proximate and ultimate explanations.
