History of evolutionary psychology
The history of evolutionary psychology began with Charles Darwin, who argued that all the most human of human capacities—the human intellect, rationality, human sexual behaviour, emotional expressions, moral behaviour, language, culture, and conscience—had evolutionary foundations, highlighting in particular those which had originated due to the unusual ways natural selection operates in social animals, that is, by different kinds of group selection, including kin selection and reciprocal altruism. Darwin's work inspired many later psychologists such as Wilhelm Wundt, James Mark Baldwin, William James, Sigmund Freud, George Herbert Mead, Konrad Lorenz and Niko Tinbergen but, in the early 1900s, American psychologists widely rejected Darwin's style of naturalistic observation in favour of laboratory experimentation.
