Evolutionary psychology is a theoretical approach to psychology that attempts to explain mental and psychological traits—such as memory, perception, or language—as adaptations, i.e., as the functional products of natural selection. The purpose of this approach is to bring an adaptationist way of thinking about biological mechanisms such as the immune system into the field of psychology, and to approach psychological mechanisms in a similar way. In short, evolutionary psychology is focused on how evolution has shaped the mind and behavior. Though applicable to any organism with a nervous system, most research in evolutionary psychology focuses on humans. Closely related fields are human behavioral ecology, dual inheritance theory, and sociobiology.
