PROJECT ABSTRACT:
Human cultural groups are not distributed evenly across the world's surface. Several authors have noted a latitudinal gradient in the densities of cultures and languages with higher densities towards the equator than towards the poles, which parallels a similar gradient seen in biological species richness. The exact mechanism by which this distribution has arisen is not well understood, however. We are applying methods and theory from evolutionary ecology and incorporating ethnographic, environmental, and ecological data using GIS technology to test different hypotheses that could explain this pattern. Initial results suggest the degree of social stratification exhibited by a society is a key factor. Further investigations, using the phylogenetic comparative method, will examine what kind of ecological factors are important in the evolution of social stratification, with a regional focus on the Austronesian-speaking societies of the Pacific. We are also using computer simulations to model the evolution of human cultural group diversity.
