Title:Evolution of social instincts in within- and between-group conflicts
Seminar:Computational and Applied Mathematics Colloquium
Speaker:Sergey Gavrilets, University of Tennessee (Host: A Belmonte)
Abstract:
I model the effects of within-group inequality on the evolution of social instincts, i.e. genetically-based propensities and biases that affect the behavior of individuals in social interactions. First, I consider competitive within-group interactions. I identify a novel mechanism for the evolutionary emergence of the "egalitarian syndrome" and leveling coalitions in which one helps the weak against the strong bully. Second, I study a collective action problem in between-group conflicts and show how bullies can dialectically become "altruists". The mechanisms I describe do not require genetic relatedness, reciprocity, reputation, or punishment.
