The work of the functionalists has developed into the field of evolutionary psychology, a branch of psychology that applies the Darwinian theory of natural selection to human and animal behaviour (Dennett, 1995; Tooby & Cosmides, 1992).

Natural selection occurs in specific populations of organisms because of several factors. It begins with overproduction. Overproduction by definition, in biology, means that each generation has more offspring than can be supported by the environment.
