A Brief History of the Theory of Evolution

Abstract A brief history of evolutionary theory illustrates its long development and sociopolitical context. Major theoretical concepts in evolutionary theory are introduced that lay the groundwork for more detailed discussion in later texts. Two incarnations of evolutionary theory—sociobiology and evolutionary psychology—are described in some detail. Criticisms of these ideas are reviewed and evaluated. Evolutionary psychology, with its emphasis on sexual selection theory, has proven to be a rich approach, generating many new insights into human sexuality.
