Abstract
The sexes usually differ in their behavior and morphology in predictable ways: males typically compete for mates and females are often choosy. However, these sex differences, known as the ‘sex roles,’ can vary substantially among and within species. We summarize the main characters that comprise sex roles, review the evolutionary causes of general patterns of sex differences, and explore how systems that deviate from these patterns can provide strong tests of sexual selection theory.
