This chapter provides empirical evidence bearing on three competing evolutionary genetic scenarios: neutral selection, mutation selection, and balancing selection. Using an innovative research design involving personality assays of inhabitants of three mainland villages and a host of nearby islands, it concludes that the findings support only the balancing selection explanation, while refuting (or finding no support for) the neutral and mutation selection scenarios.

Keywords: individual differences; personality assays; balancing selection; neutral selection; mutation selection
