Evolutionary psychology is an approach in psychology that studies the psyche of people from an evolutionary perspective. People who study this try to identify which psychological traits are adaptations that have been developed as a result of natural selection and biology. Therefore, a psychologist interested in this field would likely study other primates, as they could provide clues about the thinking and behaviour of human ancestors.
Scientists from his filed are trying to find answers for human behavior by examining the behavior of our close primate relatives (great apes like chimpanzees, gorillas, and orangutans). This field integrates the knowledge of evolutionary biology and modern psychology.
