RESUMO
OBJECTIVES: The Early Bronze Age (EBA; ca. 3,600-2000 BCE) of the southern Levant underwent considerable transformation as agro-pastoral communities began to utilize their land more intensively, constructing larger, fortified towns prior to site abandonment at the end of the third millennium. At the site of Bab adh-Dhra' in Jordan, the dead of the Early Bronze (EB) II-III (ca. 3,100-2,500 BCE) period were communally interred within charnel houses, but important disparities between these structures and their contents may be reflective of ownership and use by particular extended kin groups whose activity patterns, subsistence strategies, and even social status may have differed from one another. Subsequently, we hypothesized that differences in mobility and dietary intake may differentiate tomb groups from one another. MATERIALS AND METHODS: Dental enamel from 31 individuals interred in three different Early Bronze Age charnel houses (A56, A22, A55) at Bab adh-Dhra', Jordan were analyzed for strontium, oxygen, and carbon isotope values. RESULTS: Strontium isotope ratios (range: 0.70793-0.70842) possessed medians that did not differ statistically from one another, but had ranges that exhibited significant differences in variance. Carbon isotope values ( x¯ = -13.2 ± 0.5, 1σ) were not significantly different. DISCUSSION: General similarities in human isotopic signatures between EB II-III charnel houses A22 and A55 suggest that their activities were likely similar to one another and agree with findings from excavated domestic spaces with little archaeological evidence for economic, social, or political differentiation. More variable strontium isotope ratios and lower carbon isotope values from A22 could reflect a greater involvement with pastoralist practices or regional trade, including the consumption of more 13 C-depleted foods, while those in A55 may have led a more sedentary lifestyle with greater involvement in cultivating orchard crops. All charnel houses contained nonlocal individuals likely originating from other Dead Sea Plain sites with no EB II-III cemeteries of their own, supporting the idea that extended kin groups throughout the region returned to Bab adh-Dhra' to bury their dead.

OBJECTIVES: We estimate adult age frequencies from Unar 1 and Unar 2, two late Umm an-Nar (2400-2100 BCE) tombs in the modern-day Emirate of Ras al-Khaimah, United Arab Emirates. These collective tombs each contained hundreds of skeletons in commingled, fragmented, and variably cremated states. Previous studies placed the vast majority of this mortuary community in a generalized "adult" category, as have most analyses of similar tombs from this period. We sought to test how adult age estimation methods compare in identifying young, middle, and old-age individuals in commingled assemblages. MATERIALS AND METHODS: We employed Transition Analysis 3 (TA3) and traditional age estimation methods to generate adult age frequencies for each tomb. We compared these frequencies between tomb contexts as well as by method. RESULTS: Unar 1 and Unar 2 had similar adult age frequencies within each method, but TA3 age frequencies included significantly more middle and older adult individuals than those generated by traditional methods. DISCUSSION: These results support findings of earlier iterations of transition analysis in regard to sensitivity in old adult age estimation, compared with traditional methods. Our findings indicate a potential use of TA3 in reconstructing age frequencies and mortality profiles in commingled skeletal assemblages. Increasing our understanding of everyday life in the distant past necessitates better understandings of adult age, and here, we illustrate how age estimation method choice significantly changes bioarchaeological interpretations of aging in Bronze Age Arabia. RESEARCH HIGHLIGHTS: Adult age estimation using TA3 revealed significantly more middle and older adults than traditional methods in two commingled tombs. Similar mean maximum likelihood point estimates by side and across skeletal elements were found between tombs.

This article presents outcomes from a Workshop entitled "Bioarchaeology: Taking Stock and Moving Forward," which was held at Arizona State University (ASU) on March 6-8, 2020. Funded by the National Science Foundation (NSF), the School of Human Evolution and Social Change (ASU), and the Center for Bioarchaeological Research (CBR, ASU), the Workshop's overall goal was to explore reasons why research proposals submitted by bioarchaeologists, both graduate students and established scholars, fared disproportionately poorly within recent NSF Anthropology Program competitions and to offer advice for increasing success. Therefore, this Workshop comprised 43 international scholars and four advanced graduate students with a history of successful grant acquisition, primarily from the United States. Ultimately, we focused on two related aims: (1) best practices for improving research designs and training and (2) evaluating topics of contemporary significance that reverberate through history and beyond as promising trajectories for bioarchaeological research. Among the former were contextual grounding, research question/hypothesis generation, statistical procedures appropriate for small samples and mixed qualitative/quantitative data, the salience of Bayesian methods, and training program content. Topical foci included ethics, social inequality, identity (including intersectionality), climate change, migration, violence, epidemic disease, adaptability/plasticity, the osteological paradox, and the developmental origins of health and disease. Given the profound changes required globally to address decolonization in the 21st century, this concern also entered many formal and informal discussions.

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.
