| Abstract: |
works with 29 crown and root traits. p.98 "the eight most distinctive trait frequency differences between Sundadonty and Sinodonty involve incisor shoveling, double-shoveling, molar enamel externsions, upper third molar reduction deflecting wrinkles, and 3-rooted lower first molars, each of which is less common in Southeast Asia, while four-cusped lower second molars and two rooted upper first premolars are more common in Southeast Asians... there is no prehistoric clinal variation across Eurasia, the specialized Sinodont pattern had to have evolved out of the more generalized Sundadont pattern"
