Relatedness, class, and social organization in a village in southern Thailand

Darwinists still do not have a full theory of human social organization. Relatedness is a key idea in evolutionary theory. Yet, despite some pioneering studies, few Darwinists have used formal measures of relatedness, and even fewer have used them to describe social organization. Nobody has used relatedness to explain the rise, coherence, and decline of classes, class composition, and class relations. This article does that for one village in southern Thailand over a period of about 120 years. Each class had its own characteristic family type and relations between families, which varied over time. This article also uses the incidence of marriage between kin to show the need to take into account different perspectives on relatedness and social organization.
