Evolutionary games of cooperation: Insights through integration of theory and data

Cooperation is central to the regulation of many ecological processes and the persistence of ecosystems and their associated functions. However, the evolution of cooperation amongst non-kin appears paradoxical. Games such as the prisoner's dilemma, snowdrift and stag hunt have been borrowed from game theory and used extensively to investigate cooperation. Advances in this area have been numerous and have been provided by both empirical and theoretical studies. We outline some of the common games used and review some of the major findings and recent advancements made in this area. We show a clear link between data and theory, and how this link has been key to our understanding of cooperation.
