Ethnic nationalism, evolutionary psychology and Genetic Similarity Theory n J. PHILIPPE RUSHTON Department of Psychology, University of Western Ontario, London, Ontario, Canada ABSTRACT.Genetic Similarity Theory extends Anthony D. Smith’s theory of ethno-symbolism by anchoring ethnic nepotism in the evolutionary psychology of altruism. Altruism toward kin and similar others evolved in order to help replicate shared genes. Since ethnic groups are repositories of shared genes, xenophobia is the ‘dark side’ of human altruism. A review of the literature demonstrates the pull of genetic similarity in dyads such as marriage partners and friendships, and even large groups, both national and international. The evidence that genes incline people to prefer others who are genetically similar to themselves comes from studies of social assortment, differential heritabilities, the comparison of identical and fraternal twins, blood tests, and family bereavements. DNA sequencing studies confirm some origin myths and disconfirm others; they also show that in comparison to the total genetic variance around the world, random co-ethnics are related to each other on the order of first cousins. Introduction Most theories of ethno-political conflict and nationalism focus on cultural, cognitive and economic factors, often with the assumption that modernisation will gradually reduce the effect of local antagonisms and promote the growth of more universalistic societies (Smith 1998). However, purely socio-economic explanations seem inadequate to account for the rapid rise of nationalism in the former Soviet Bloc and too weak to explain the lethality of the conflicts between Tutsis and Hutus in Rwanda, Hindus, Muslims and Sikhs in the Indian subcontinent, and Croats, Serbs, Bosnians and Albanians in the former Yugoslavia, or even the level of animosity between Blacks, Whites Nations and Nationalism11(4), 2005, 489–507.rASEN 2005 n This article builds on a paper prepared for the American Psychologi…
