We All Have Genetic Interests, April 24, 2004
The need to identify with others like oneself, and to be with one's own kind, is a major component of human nature and so ethnic identity is a powerful force in human affairs. Group members have "ties of blood" that make them "special" and different from outsiders. This is why patriotism is almost always seen as a virtue and an extension of family loyalty. It also explains why ethnic remarks so easily become "fighting words." Culture builds on genetic similarity and is bound together by it. Patriotism is preached in kinship terms. Nations are the "motherland" or the "fatherland" and unions and churches refer to their members as "brothers" and "sisters."Salter draws out the implications, however politically incorrect, for immigration policies, citizenship law, affirmative action, multiculturalism, and other ways of allocating resources within and between states. There are constraints on how much diversity can be appreciated. On Genetic Interests extends evolutionary theorizing, including my own Genetic Similarity Theory, to the new ground of interpersonal and ethnic relations such as within-group cohesion and between-group conflict. It discusses studies on likeness in social partners such as spouses and best friends. Most importantly, it applies genetic calculations and finds that the average coefficient of kinship within most ethnic groups is about as high as between half-siblings, aunt and nephew, or grandparent and grandchild. Thus, ethnic nepotism is no mere poor relation of family nepotism-it is virtually a proxy for it. Because we have many more co-ethnics than relatives, the aggregate mass of genes shared with the former dwarfs that shared with the latter. Frank Salter, a political scientists and ethologist at the Max Planck Institute in Munich, argues persuasively in this book that shared genes are the glue of sociality.On Genetic Interests goes so far as to refer to the mind as having an "innate descent-group module" (p. 102). It uses this concept to explain the universality of ethnic nepotism. This is heartening because many social scientists and sociobiologists alike have been reluctant to even consider applying gene-based similarity to ethnic and national preferences. Following World War II, few political scientists and historians have considered inter-group conflict from a Darwinian viewpoint. Partly in an effort to insure that they are perceived as in no way condoning racism, many evolutionists have minimized the theoretical possibility of a biological underpinning to ethnic, national, and racial favoritism. As the late, great, evolutionary biologist William Hamilton himself remarked in 1987, while noting why kin discrimination even among animals is not more readily expected, "in civilized cultures, nepotism has become an embarrassment." Social scientists and historians have been quick to condemn the extent to which political leaders or would-be leaders have been able to manipulate ethnic identity. But the questions they never ask, let alone attempt to answer is, "Why is it always so easy?" and "Why can a relatively uneducated political outsider set off a race riot simply by uttering a few well delivered ethnic epithets?" On Genetic Interests provides an illuminating answer.
