Theoretical approaches to bioarchaeology: The view from across the pond

This chapter explores the development and integration of social theory in bioarchaeology from the perspective of the UK and France, and in relation to North America. It examines the constraining influence of traditional academic structures, which have perpetuated the social theory/science, mind/body divide. These structures have created disciplinary barriers that have had an impact on the exposure to—and reception of—social theory within bioarchaeology. Additionally, language and geographical barriers have also resulted in different theoretical trajectories within the UK and France, with the former being most closely allied to North America. Finally, we examine the student experience of learning social theory within different countries and academic structures, and the pedagogical benefits of an integrated and applied social bioarchaeology when teaching the discipline

Height and health in Roman and Post-Roman Gaul, a life course approach

Objective: The present study explores growth and health in Roman (1st-3rd centuries CE) and Post-Roman (4th-7th centuries CE) Gaul, incorporating a life-course approach, to better understand the influence of Roman practices and lifestyles on health, and the impact of cultural change from the Roman to the Post-Roman period. Materials and Methods: The skeletal remains of 844 individuals were analyzed for non-specific signs of physiological stress, including growth disruption (diaphyseal and adult maximum femur length), dental enamel hypoplastic defects (DEH), cribra orbitalia (CO), and periosteal reaction of the tibiae (Tibia PR). Results: The Gallo-Roman sample demonstrated shorter femoral lengths, and higher rates of DEH and Tibia PR. Post-Roman groups demonstrated longer femoral lengths and higher rates of CO. Conclusions: Gallo-Roman individuals may have been more regularly exposed to infectious pathogens throughout childhood, inhibiting opportunities for catch-up growth, resulting in high rates of DEH and shorter femoral lengths (‘intermittent stress of low lethality’). This could be the result of overcrowding and insalubrious urban environments. Higher rates of CO in the Post-Roman samples may have been influenced by dietary changes between the periods. Significance: The intertwined and often synergistic relationships between early life environment, nutrition and settlement structure is highlighted, helping to further understandings of life experiences during the Roman and Post-Roman periods. Limitations: It was not possible to obtain sufficient data from northern regions during the Gallo-Roman period, limiting this analysis. Suggestions for Further Research: Further application of life course approaches can reveal subtle patterns in stress indicators

Compounding vulnerabilities: Syndemics and the social determinants of disease in the past

Objective: This article explores the theory and utility of a syndemic approach for the study of disease in the past. Syndemic principles are examined alongside other theoretical developments within bioarchaeology. Two case studies are provided to illustrate the efficacy of this approach: Tuberculosis and vitamin D deficiency in 18th and 19th century England, and malaria and helminth infections in Early Medieval England. Materials: Public health studies of present syndemics, in addition to published bioarchaeological, clinical and social information relating to the chosen case studies. Methods: The data from these two historical examples are revisited within a syndemic framework to draw deeper conclusions about disease clustering and heterogeneity in the past. Results: A syndemic framework can be applied to past contexts using clinical studies of diseases in a modern context and relevant paleopathological, archaeological, and historical data. Conclusions: This approach provides a means for providing a deeper, contextualised understanding ancient diseases, and integrates well with extant theoretical tools in bioarchaeology Significance: Syndemics provides scholars a deep-time perspective on diseases that still impact modern populations. Limitations: Many of the variables essential for a truly syndemic approach cannot be obtained from current archaeological, bioarchaeological, or historical methods. Suggestions for further research: More detailed and in-depth analysis of specific disease clusters within the past and the present, which draws on a comprehensive analysis of the social determinants of health

Desperately seeking stress: A pilot study of cortisol in archaeological tooth structures

Objectives: Cortisol is a glucocorticoid hormone produced through activation of the hypothalamic pituitary adrenal axis. It is known as the “stress hormone” for its primary role in the body's stress response and has been the focus of much modern clinical research. Within archaeology, only a few studies have analyzed cortisol in human remains and these have been restricted to hair (Webb et al., 2010; Webb, White, van Uum, & Longstaffe, 2015a; Webb, White, van Uum, & Longstaffe, 2015b). This study examines the utility of dentine and enamel, which survive well archaeologically, as possible reservoirs for detectable levels of cortisol. Materials and methods: Then, 69 teeth from 65 individuals from five Roman and Post-Roman sites in France were tested via competitive enzyme-linked immunosorbent assay (ELISA) to assess and quantify the cortisol concentrations present within tooth dentine and enamel. Results: In both tooth dentine and enamel, detectable concentrations of cortisol were identified in multiple teeth. However, concentrations were low and not all teeth yielded results that were measurable through cortisol ELISA. Differences in cortisol values between dentine and enamel could suggest different uptake mechanisms or timing. Discussion: These results suggest that cortisol is incorporated within tooth structures and merits further investigation in both modern and archaeological contexts. Analysis of the results through liquid chromatographic–mass spectrometry would verify current results and might yield values that could be better integrated with published cortisol studies. Future studies of cortisol in tooth structures would greatly expand the research potential of cortisol in the past and could have implications for studies of human stress across deep time

The Children of the Reformation: Childhood Palaeoepidemiology in Britain, ad 1000–1700

CHILDHOOD IS A TIME of rapid biological growth and development, and a stage of the life course during which bodies are particularly sensitive to social and environmental stressors. As a consequence, events which may impact upon a child’s care and treatment can become physically embodied within their bones and teeth. The skeletal remains of children have been neglected within archaeological discourse until recently, but they are, in fact, a particularly important demographic for understanding the impact of social processes on past population health. This research examines the prevalence of skeletal disease in children (≤16 years) in Britain (England, Wales and Scotland) between ad 1000 and 1700. Data for a total of 4,626 children from 95 sites were collated from published and unpublished skeletal reports and analysed for evidence of skeletal changes reflecting disease. A biocultural approach was adopted in which the evidence was interpreted in relation to ecological, social, economic and environmental conditions. It was observed that childhood levels of skeletal stress did increase significantly after 1540. It was noted that during the Reformation sociocultural and economic factors added to stressors in the ecology of the medieval child. The effects of the Reformation were found to be the greatest aggravator in the rise of morbidity prevalence over seven centuries. Differences in morbidity patterns between non-adult age categories indicated that a state of ‘childhood’ existed until at least eleven years of age, after which there appears to have been a gradual transition into adolescence and adulthood

Alloparenting Adolescents: Evaluating the Social and Biological Impacts of Leprosy on Young People in Saxo-Norman England (9th to 12th Centuries AD) through Cross-Disciplinary Models of Care

The majority of historical sources describe past attitudes towards people with leprosy as negative, focussing on ostracism and damnation, and this is thought to have impacted on the care that sufferers received. More recent historical and archaeological evidence challenges this longstanding perspective, portraying a very different view of care for those with this potentially debilitating and disfiguring disease (Roberts 2002; Rawcliffe 2006; Roberts 2013; Roberts 2018). This paper aims to explore the social and biological impacts of adolescents with leprosy in SaxoNorman England (9th – 12th centuries AD). The intersection of youth, chronic infection, aspects of care (inclusive of medical, surgical, and daily support), and cultural identity has only been tangentially explored in the past (e.g see Redfern and Gowland 2011; Roberts and Bernard 2015; Lewis 2017). Studies that integrate these entwined themes can, however, provide a more holistic view of societal responses to wider encultured disease identities. This study utilises multiple lines of evidence for medical care and social treatment to evaluate the validity of dominant historical narratives about leprosy, i.e. that people in the past with leprosy were not cared for or treated well. In order to achieve this, the notion of past requirements of care and treatment through an alloparental model will be introduced. This is followed by a review of the existing historiographical evidence for medical care for young people in the medieval period to better understand systems of care provision and parental reactions to their sick children at this time. Discussions of leprosy in young people in the present and past will help contribute to longitudinal views of the biological impacts of leprosy and help the necessity for care in relation to certain pathological responses (i.e. the manifestation of lepromatous leprosy). To apply this framework to the past, palaeopathological and archaeological evidence from adolescent individuals excavated from the North Cemetery of St. Mary Magdalen leprosy hospital will be analysed. The presence of both leprosy and alloparental care for adolescents in the Saxo-Norman transition at this hospital is demonstrated. Finally, the construction of a theoretical model of required clinical care and provisions, such as the Index of Care framework, helps interpret the evidence for care in alloparental institutions such as leprosaria. The treatment of people with leprosy in the medieval period is often cited as a justification for the continuing stigma and community expulsion of family members with leprosy in some parts of the world (World Health Organization 2015). Therefore, it is worth examining the social milieu of this disease in which young people with leprosy in the past lived, and the models of care and treatment that may be interpreted from these data in order to dispel this longstanding stigma

Sex determination of human remains from peptides in tooth enamel

The assignment of biological sex to archaeological human skeletons is a fundamental requirement for the reconstruction of the human past. It is conventionally and routinely performed on adults using metric analysis and morphological traits arising from postpubertal sexual dimorphism. A maximum accuracy of ∼95% is possible if both the cranium and os coxae are present and intact, but this is seldom achievable for all skeletons. Furthermore, for infants and juveniles, there are no reliable morphological methods for sex determination without resorting to DNA analysis, which requires good DNA survival and is time-consuming. Consequently, sex determination of juvenile remains is rarely undertaken, and a dependable and expedient method that can correctly assign biological sex to human remains of any age is highly desirable. Here we present a method for sex determination of human remains by means of a minimally destructive surface acid etching of tooth enamel and subsequent identification of sex chromosome-linked isoforms of amelogenin, an enamel-forming protein, by nanoflow liquid chromatography mass spectrometry. Tooth enamel is the hardest tissue in the human body and survives burial exceptionally well, even when the rest of the skeleton or DNA in the organic fraction has decayed. Our method can reliably determine the biological sex of humans of any age using a body tissue that is difficult to cross-contaminate and is most likely to survive. The application of this method will make sex determination of adults and, for the first time, juveniles a reliable and routine activity in future bioarcheological and medico-legal science contexts
