OBJECTIVES: Crown and root traits, like those in the Arizona State University Dental Anthropology System (ASUDAS), are seemingly useful as genetic proxies. However, recent studies report mixed results concerning their heritability, and ability to assess variation to the level of genomic data. The aim is to test further if such traits can approximate genetic relatedness, among continental and global samples. MATERIALS AND METHODS: First, for 12 African populations, Mantel correlations were calcul...

Bailey et al. (1) describe a lower second molar with 3 roots in a Denisovan hemimandible dated 160,000 ka. The presence of a third root is stated to occur in <3.5% of non-Asians and in up to 40% of Asians and some New World populations. From this, they conclude the feature “provides morphological evidence of a strong link between archaic and recent Asian H[omo] sapiens populations. This link provides compelling evidence that modern Asian lineages acquired the 3-rooted lower molar via introgressi...

Objective: Turner syndrome (TS) and Klinefelter syndrome (KS) represent the two most common X chromosome aneuploidies, each associated with systemic disruptions to growth and development. Effects of these conditions on tooth crown morphology are explored in a sample of Croatian individuals. Materials and Methods: The sample included 57 TS, 37 KS and 88 control individuals. Dental crown morphology was scored on dental casts according to the Turner-Scott Dental Anthropology System. Results: Inciso...

Because of the ubiquitous adaptability of our material culture, some human populations have occupied extreme environments that intensified selection on existing genomic variation. By 32,000 years ago, people were living in Arctic Beringia, and during the Last Glacial Maximum (LGM; 28,000–18,000 y ago), they likely persisted in the Beringian refugium. Such high latitudes provide only very low levels of UV radiation, and can thereby lead to dangerously low levels of biosynthesized vitamin D. The p...

The aims of this study are to describe the frequency of occurrence and degree of expression of the parastyle in six different ethnic groups; to assess inter- and intra-observer errors when scoring the feature; and to compare the expression of the feature in a small number of twin pairs. Dental casts were examined for evidence of the parastyle from samples available in the Adelaide Dental School. A dental plaque developed by Katich & Turner was used to standardize scoring. The highest percentage ...
