Mandibular premolar and second molar root morphological variation in modern humans
This investigation of modern human mandibular premolar root variation tests the hypothesis that population-specific mandibular single-rooted premolar root size can predict a predisposition to root morphological complexity. Mandibular postcanines were examined and quantified from dental radiographs in a globally spread sample of 1,615 modern humans. Multirooted premolars and a fused molar root phenotype were investigated as probes into greater tha…
Technical note
The anatomic distribution of the Stafne static mandibular bone defect (SSBD) is extended with a description of a cavitation defect on the buccal ramus of the mandible. The anatomical placement of SSBD thus correlates precisely with the submandibular and parotid salivary glands, and gives further evidence that an increase in major salivary gland size is associated with the defect. The global latitudinal variation in the population prevalence of SS…
Dorset and Thule divergence from east Central Asian roots
The history of the immigration of East Asians to America during the last glacial period remains controversial. In an attempt to add critical data to this problem, a large sample of whole teeth derived from Southeast Asian, Mongolian, Thule, Western Inuit, and pre-Inca (Huari) people was quantified (N = 4,507 teeth from 495 individuals; ∼30 variables per tooth). Multivariate analysis helped establish that all Native Americans were likely derived f…

Heterochronic quantitative microevolution
Studies of tooth crown morphology alone have proven valuable in defining human population differentiation. We test the hypothesis that quantitative comparisons of more complex whole tooth structure may prove informative in understanding human diversity. Three disparate populations in Native American genetic history were compared: Kodiak Island Western Eskimos, Peruvian Inca Amerindians, and Southeast Asians. Enamel depth (an increasing gradient e…
