Evolutionary psychology has been dominated by one particular method for studying the mind and behavior. This is the first book to both question that monopoly and suggest a broad range of particular alternatives. Psychologists, philosophers, biologists, anthropologists, and others offer different methods for combining psychology and evolution. They recommend specific changes to evolutionary psychology using a wide variety of theoretical assumptions. In addition, some essays analyze the underpinnings of the dominant method, relate it to the context of evolutionary and psychological theory and to general philosophy of science, and discuss how to test approaches to evolutionary psychology. The aim of this collection is not to reject evolutionary psychology but to open up new vistas which students and researchers can use to ensure that evolutionary psychology continues to thrive.
