What is Evolutionary psychology?
'''Evolutionary psychology''' is a branch of [[psychology]] that investigates [[behaviour|behavior]] which has [[evolution|evolved]]. It is similar in this respect to [[ethology]], which has always used ideas from [[evolutionary biology]]. ==Abstract== This field seeks to identify which human psychological traits are evolved [[adaptation]]s, that is, functional products of [[natural selection]] or [[sexual selection]]. Evolutionary psychology usually focuses on behavior most people share. Sex and social behavior are some of the more common areas that evolutionary psychology focuses on.<ref>Ardrey, Robert 1961.
