This chapter reviews the utility of nonmetric traits from the Arizona State University Dental Anthropology System (described previously in this volume), as recorded in samples, to characterize and compare populations at geographic scales ranging from global to local. Holding several advantages over other hard tissue morphometric, as well as genetic, data, the inter-sample affinities based on dental morphology can reliably estimate biological relatedness at a broad level. To illustrate these points, information concerning previous and more recent biodistance dental studies from around the world is presented, along with a concluding case study; the latter entails comparison of a recently recorded “unknown” South African sample with four previously recorded regional groups to demonstrate the step-by-step approach for obtaining, visualizing, and interpreting numerically derived affinities.
