Adaptationism is a term used in evolutionary biology to describe the idea that all biological traits, including behavior, have evolved because they are adaptive. Synonyms for adaptationism include evolutionary biology, evolutionary psychology, and sociobiology. These terms are related to adaptationism because they explore how evolution has shaped organisms over time. However, they also differ slightly in their focus and methods. Evolutionary biology focuses on the mechanisms and patterns of evolutionary change, while evolutionary psychology looks at how evolution has shaped the human mind. Sociobiology examines the social behavior of animals, including humans, from an evolutionary perspective. All of these areas of study contribute to our understanding of how organisms have adapted to changing environments over time.
