An integrative evolutionary perspective on ethnicity.
This paper integrates several different but mutually consistent evolutionary approaches to ethnicity: genetic similarity theory, social identity theory, individualism/collectivism, an evolved racial/ethnic human kinds module, and rational choice mechanisms relying on domain general cognitive mechanisms. These theories are consistent with each other, and together they illustrate the interplay of evolved cognitive and motivational systems with mechanisms of rational choice that are able to choose adaptive strategies in uncertain, novel environments.
