The role of diversity in the evolution of cooperation abstract Understanding the evolutionary mechanisms that promote and maintain cooperative behavior is recognized as a major theoretical problem where the intricacy increases with the complexity of the participating individuals.This is epitomized by the diverse nature of Human interactions,contexts, preferences and social structures. Here we discuss how social diversity, in several of its ?avors, catalyzes cooperative behavior. From the diversity in the number of interactions an individual is involved to differences in the choice of role models and contributions, diversity is shown to Signi?cantly increase the chances of cooperation.Individual diversity leads to an overall population Dynamics in which the underlying dilemma of cooperation is changed,bene?ting the society as whole. In addition, we show how diversity in social contexts can arise from the individual capacity for Organizing their social ties.As such,Human diversity,on a grand scale,may be instrumental in shaping Us as the most sophisticated cooperative entities on this planet. 1. Introduction Merriam Webster defines diversity as‘‘the condition of having Or being composed of differing elements’’.Considering the broad Scope of the term,it may legitimately be pointed out that the title Of this manuscript is perhaps far more presumptuous than its actual contents. Indeed, we scratch at most of the surface of Diversity in its relation to the evolution of cooperation.Even so, We find something that may be seen at first as counter-intuitive: Diversity promotes the evolution of cooperation. Or, at least, When one considers the different aspects of diversity that have Been investigated so far. Historically,the evolution of cooperation has been studied in The absence of diversity.It was found more Reasonable to deal with the evolution of cooperation in a population Of identical individuals,as de?ned by conventional evolutionary game theory.Every individua
