    When in Rome, do as the Romans do: the coevolution of altruistic punishment, conformist learning, and cooperation
    (ELSEVIER SCIENCE INC, 2007) Guzman, Ricardo Andres; Rodriguez Sickert, Carlos; Rowthorn, Robert
    We model the coevolution of behavioral strategies and social learning rules in the context of a cooperative dilemma, a situation in which individuals must decide whether or not to subordinate their own interests to those of the group. There are two learning rules in our model, conformism and payoff-dependent imitation, which evolve by natural selection, and three behavioral strategies, cooperate, defect, and cooperate, plus punish defectors, which evolve under the influence of the prevailing learning rules. Group and individual level selective pressures drive evolution.
