“…These standards are widely used today and were selectively incorporated into the Standards manual (Buikstra & Ubelaker, ), thus assuring that many tens of thousands of individuals have been observed for dental morphological variation (see also Scott & Irish, ; Scott, Turner, Townsend, & Martinón‐Torres, 2018). Continued interest in dental morphology is evidenced by the recent publication of multiple synthetic volumes (Edgar, ; Scott & Irish, ; Scott et al, a) and multiscalar applications in bioarchaeological contexts (e.g., McIlvaine, Schepartz, Larsen, & Sciulli, ; Reyes‐Centeno, Rathmann, Hanihara, & Harvati, ; Scott et al, b; Thompson, Hedman, & Slater, ). However, if phenotypic datasets are ever to approach genetic datasets in their quality and resolution, continued validation research on the biological underpinnings of crown variation is necessary to inform analytical assumptions and methods.…”

Additive genetic variation contributes to dental morphological variation, although the estimates are uniformly lower than those observed for odontometrics. Patterns of genetic correlation affirm most standard practices in dental biodistance. Patterns of negative pleiotropy involving lingual and labial crown features suggest a genetic architecture and developmental complex that differentially constrain morphological variation of distinct surfaces of the same tooth crown. These patterns warrant greater consideration and cross-population validation.

The potential of statistical shape modelling for geometric morphometric analysis of human teeth in archaeological research

This paper introduces statistical shape modelling (SSM) for use in osteoarchaeology research. SSM is a full field, multi-material analytical technique, and is presented as a supplementary geometric morphometric (GM) tool. Lower mandibular canines from two archaeological populations and one modern population were sampled, digitised using micro-CT, aligned, registered to a baseline and statistically modelled using principal component analysis (PCA). Sample material properties were incorporated as a binary enamel/dentin parameter. Results were assessed qualitatively and quantitatively using anatomical landmarks. Finally, the technique’s application was demonstrated for inter-sample comparison through analysis of the principal component (PC) weights. It was found that SSM could provide high detail qualitative and quantitative insight with respect to archaeological inter- and intra-sample variability. This technique has value for archaeological, biomechanical and forensic applications including identification, finite element analysis (FEA) and reconstruction from partial datasets.

“…The dental metric dataset consists of 32 mesiodistal (MD) and buccolingual (BL) crown and cervical diameters of the permanent teeth recorded for each individual. Only polar teeth were recorded (UI1, UC, UP3, UM1, LI2, LC, LP3, LM1) in order to reduce genetic covariation between traits, and to minimize potential effects of fluctuating asymmetry and ontogenetic plasticity on adult tooth size (Butler, ; Dahlberg, ; Sciulli & Cook, ; see also Stojanowski, , ; Thompson, Hedman, & Slater, ). Only left teeth were measured, but when a left tooth was missing, damaged, or affected by wear or pathology, the corresponding right antimere was measured.…”

Objectives:We are testing competing scenarios regarding the population history of the ancient Greek colonization of southern Italy using dental phenotypic evidence. Materials and Methods:We collected dental metric and nonmetric trait data for 481 human skeletons from six archaeological sites along the Gulf of Taranto, dating to pre-colonial (900-700 BC) and post-colonial periods (700-200 BC). We are evaluating scenarios through an individual-level biodistance analysis using a three-pronged approach: (a) by analyzing levels of mobility in pre-and post-colonial periods under a model of isolation-by-distance; (b) by quantifying differences in group means and variances in pre-and post-colonial periods utilizing permutational multivariate analysis of variance and Betadisper analyses; and (c) by identifying ancestries of post-colonial individuals using naïve Bayes classification. Results: Southern Italy during pre-colonial times was characterized by low levels of mobility and marked differences in group means and variances. During post-colonial times, mobility increased and there were no differences in group means and variances. About 18% of the people in post-colonial times were of Greek ancestry and lived equally distributed across Greek colonies and indigenous villages. Nevertheless, the overall biological composition and variability of southern Italy remained relatively unchanged across pre-and post-colonial periods. Discussion: Our results support a scenario in which only few Greek colonists migrated to southern Italy and lived in smaller numbers alongside indigenous people in Greek colonies as well as in indigenous villages. Our results contradict a scenario in which large numbers of Greek invaders founded biologically isolated and substantially homogeneous colonial enclaves within conquered territories.
