This explores the relationship between population size, genetic diversity, and cultural conservatism. It argues that small, isolated populations tend to exhibit greater physical variation due to inbreeding, while simultaneously maintaining cultural stability because of the precariousness of their existence. In contrast, larger populations show more physical uniformity but greater cultural diversification. The author uses this principle to explain the observed characteristics of early human remains and the persistence of certain cultural traits across geographically diverse regions, suggesting that the early human population, dispersed after a catastrophic event, would have displayed such patterns of variation and uniformity, pointing to the Biblical record as background.
