Sinodont Vs. Sundadont
Definition
Turner's two-pattern model of dental morphology variation in Asia and the Pacific. Sinodonts (northern Asian, East Asian, Indigenous American) have high frequencies of shovelling, double-shovelling, and single-rooted upper premolars. Sundadonts (Southeast Asian, Pacific) have lower frequencies of these traits and a somewhat simpler dental morphology.
