Abstract

Presents a simple model that, in principle, can be used to predict the degree of sexual dimorphism in a given species. Two episodes of selection acting directly on body size during an animal's lifetime are considered: natural selection and reproductive selection. A general hypothesis is derived concerning the expected relationship between sexual dimorphism and reproductive selection pressures acting on body size in males and females. This hypothesis is tested using comparative data on sexual dimorphism in anurans.
