In 1969, I began a field study of the social behavior of two Jamaican lizards, Anolis garmani and A. valencienni. This study has developed into an attempt to measure how sexual selection has molded adult dimorphism in size and associated dimorphism in growth rates, mortality rates, and in sexual and aggressive behavior. Preliminary data for Anolis garmani were presented as part of a general theory for the evolution of sex differences (Trivers, 1972). Meanwhile, several important theoretical advances (Maynard Smith, 1971; Williams, 1975; Zahavi, 1975) have convinced me that female choice is a central factor molding male sexual dimorphism and systems of malemale competition. The data presented here for Anolis garmani tend to support the view that those males who do most of the mating are those who have tended to demonstrate the superiority of their non sexlinked genes.
