Although archaeological evidence may express the results of several seasons of activity, the human skeleton, when correlated with archaeological and ethnographic data, provides information concerning daily activities performed throughout an individual's lifetime. Studies in occupational and sports medicine, along with electromyographic analysis of movement, have shown that different activities place different amounts of stress on human bone. In the present study, analysis of upper extremity musculoskeletal stress markers (MSM) has been used to clarify habitual activity patterns of two ancient Thule Eskimo groups from northwest Hudson Bay, Canada. Distinct pattern differences in muscle use occurred between Thule adult males and females and suggest possible gender-specific activity patterns that are not always discernible from the archaeological record alone. Temporal applications of the MSM data for Early and Late Period Thule support McCartney's theory of a substantial change in subsistence strategies through time, particularly among the adult males.

The purpose of this brief communication is to report the results of an analysis of maxillary premolar accessory ridges (MxPAR), a common but understudied accessory ridge that may occur both mesial and distal to the central ridge of the buccal cusp of upper premolars. We developed a new five-grade scoring plaque to better categorize MxPAR variation. Subsequently, we conducted a population analysis of MxPAR frequency in 749 dental casts of South African Indian, American Chinese, Alaskan Eskimo, Tohono O'odham (Papago), Akimel O'odham (Pima), Solomon Islander, South African Bantu, and both American and South African Whites. Northeast Asian and Asian-derived populations exhibited the highest MxPAR frequencies while Indo-European samples (South African Indians, American and South African Whites) exhibited relatively low frequencies. The Solomon Islanders and South African Bantu samples exhibited intermediate frequencies. Our analysis indicates that statistically significant differences in MxPAR frequency exist between major geographic populations. As a result, the MxPAR plaque has now been added to the Arizona State University Dental Anthropology System, an important contribution as maxillary premolar traits are underrepresented in analyses of dental morphology.

To many Near Eastern archaeologists, the Late Bronze Age-Early Iron Age transition in the southern Levant indicates the emergence of a new ethnicity. The question remains, however, whether changes in the material culture are the result of an invasion of foreigners, or instead arose from shifting cultural and technical practices by indigenous peoples. This study utilized dental morphological traits to assess phenetic relationships between the Late Bronze Age site of Dothan (1500-1100 BC) and the Iron Age II site of Lachish (Tell ed-Duweir, 701 BC). Information on 30 dental crown and root traits was collected for 4,412 teeth, representing 392 individuals from Lachish and a minimum of 121 individuals from Dothan, using the Arizona State University Dental Anthropology System. Seventeen traits from Dothan and Lachish were compared with dentitions from a Byzantine Jerusalem monastery, Iron Age Italy, a Natufian group (early agrarians from the Levant), and a Middle Kingdom Egyptian site using C.A.B. Smith's mean measure of divergence statistic. The findings suggest that there are more similarities between Dothan and Lachish than either of them and other sites. This analysis indicates that the material culture changes were not the result of a foreign invasion. Rather, the Iron Age people of the southern Levant were related to their Bronze Age predecessors.
