This chapter explores the intersection of bioarchaeology, cultural theory, and the study of the human body, focusing on how biological, cultural, and social factors shape lived experiences across time through the lens of the Three Bodies Model put forth by Scheper-Hughes and Lock. Bioarchaeological analysis provides a unique lens through which researchers can trace physical evidence of trauma, disease, and stress in skeletal remains, offering insights into historical health and social dynamics. The Three Bodies Model conceptualizes the body as an physical object as well as a social and political entity, offering a framework for understanding how cultural processes shape physical bodies. The Three Bodies Model is examined in relation to other concepts used in bioculturally engaged bioarchaeology. The concept of social buffering is introduced, illustrating how cultural norms and social structures can either protect or expose individuals to risks. Power dynamics are also examined with relation to the Three Bodies Model, Practice, and Structuration, exploring how individual agency and social structures shape lived experience and are inscribed on bone. The role of intersectionality is introduced as a critical framework for understanding how overlapping social identities (such as gender, age, social race, and socioeconomic status) influence both cultural practices and physical health. By integrating intersectionality into bioarchaeological analysis, scholars have argued that skeletal trauma and health disparities can be understood to be the product of complex, interwoven social and biological factors. Finally, the boundaries of the bodies are explored, with an emphasis on fluidity and the complex interplay between physical bodies, material culture, and social context. The interpretation of bioarchaeological data requires an understanding of the specific archaeological, historical, and cultural context in which human remains are found to provide a holistic understanding of lived experience in the past.
