There are two learning rules in our model, <em>conformism<\/em> and <em>payoff-dependent imitation<\/em>, which evolve by natural selection; and three behavioral strategies, <em>cooperate, defect, and cooperate and punish defectors<\/em>, which evolve under the influence of the prevailing learning rules. Group and individual level selective pressures drive evolution.<\/p>\n<p>We also simulate our model for conditions that approximate those in which early hominids lived. Contrary to previous claims, we find that conformism can evolve when the only problem individuals face is a cooperative dilemma. Furthermore, the presence of conformists dramatically increases the group size for which cooperation can be sustained. The results of our model are robust: they hold even when migration rates are high, and when conflict among groups is infrequent.<\/p>\n<p><a href=\"https:\/\/gobierno.udd.cl\/cics\/files\/2012\/07\/Romans-Guzman-Rodriguez-Rowthotn-2006.pdf\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-85 alignnone\" title=\"PDF\" src=\"https:\/\/gobierno.udd.cl\/cics\/files\/2012\/07\/pdf-cics.jpg\" alt=\"\" width=\"40\" height=\"40\" \/><\/a><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Evolution and Human Behavior, Vol. 28, N\u00b02, pp. 112\u2013117.
