As critical epidemiologist Nancy Krieger (2001, p. 674) comments, it is important to think “critically and systematically about intimate and integral connections between our social and biological existence – and, especially in the case of social production of disease and ecosocial theory, to name explicitly who benefits from and is accountable for social inequalities in health.”

      Dialectics of Biocultural Interactions Because culture and lived experience is embodied in bodies and biology, and bodies and biology mediate lived experience, an understanding of human biology and biological processes can add a layer of information and viewpoint that is too often missed. Krieger (2001), for example, highlights the importance of following multiple “pathways of embodiment” that link social conditions to health. Such analyses can reach below the skin to show how daily events, linked to political-economic processes, affect skinfold thicknesses, blood pressures, stress hormones, rates of parasitism and anemia, and cumulative fertility and mortality rates. Demonstrating these relationships often requires direct measures of biological status, and examinations of the biological processes linking local-level experiences to biological outcomes. Over the past several decades, a host of new “biomarkers” employed by biocultural anthropologists have expanded the ability to track pathways of embodiment linking social conditions to biology and health (McDade and Harris 2018). One arena in which we can see the focus on biology as illuminating processes of inequality is through enhanced understandings of the biological pathways involved in syndemics, the synergistic interaction of multiple diseases (or stressors) that amplify negative health consequences (Singer and Mendenhal, this volume, Mendenhall et al. 2017 ; Singer 2009; Singer and Clair 2003). The diseases that make up syndemics are often linked through pathways that connect to underlying conditions of poverty and structural inequalities. Just as following pathways of embodiment (Krieger 2005) to trace the many ways lived experience becomes biology, it is also important to trace the reciprocal effects of biology on social and cultural life; embodied responses to environmental stressors reshape human–environment interactions. Humans and their environments are co-constructed, relational, and constantly in flux (Hoke and Schell 2020). In the words of Ingold and Palsson (2014), we are always “biosocial becomings.” Thus, critical biocultural approaches adopt a dialectical perspective on biocultural interactions; the biological and social and cultural elements of bodies are inextricably braided and mutually constitutive.

      CRITICAL BIOCULTURAL APPROACHES IN STUDIES OF HUMAN HEALTH

      Given the roots of many critical biocultural anthropological studies of health in processes of evolution and development as well as political economy, a series of theoretical and methodological shifts in studies of human biology over the past several decades have tremendous implications for the way bodies are framed and for the ability to link social inequalities to biology and health through specific pathways of embodiment.

      Within the areas of evolution and development, there has been a renewed attention to biological plasticity, niche construction, and multiple modes of inheritance as part of an extended evolutionary synthesis (Fuentes 2016; Hoke and McDade 2015) that make more legible links between social relations of power and biology (Hicks and Leonard 2014). Tracing pathways of embodiment to ground these conceptual links have been facilitated by advances in new field methods of biological measurement (e.g., the collection of dried blood spots and other biomarkers) that can provide data on multiple physiological pathways, including neuroendocrine, cardiopulmonary, and immune/inflammatory, through which social factors can contribute to health (McDade and Harris 2018; Worthman and Costello 2009).

      The recognition of the impact of early stress on later health, framed in terms of fetal and/or metabolic programming and developmental origins of health and disease (DOHaD), and the role that epigenetics and the microbiome play in biology and health, are significant areas of advancement that have obvious implications for a critical biocultural medical anthropology. Perhaps the best-known example is the thrifty phenotype hypothesis that proposes a relationship between prenatal and early life nutrition and adult obesity, diabetes, and cardiovascular disease (Barker et al. 2002; Hales and Barker 2001), especially where there is a mismatch between the nutritional landscape during fetal development and the subsequent life-course. Such studies have advanced biocultural anthropology by working against genetic determinism and revealing instead the complex interplay between genetics, life course, and environments in the embodiment of human experiences. They have also helped shift perspectives on human variation toward situated bodies and biologies (Lock 2017) over universal bodies and biologies.

      Multispecies interactions, holobionts and hologenomes, and metaphors of “unstable bodies” (Palsson 2016) and biosocial becomings (Ingold and Palsson 2014) speak to the relationality of all organisms and the irreducible interpenetration of the social and biological. As Fuentes (2019, p. 157) notes, “Bypassing the conceptualization of the biological, social, and ecological as distinct domains, and thinking of them as obligatorily intertwined processes of becoming (e.g., Ingold 2000 ), presents a powerful lens for understanding ourselves and our relationships with others in the Anthropocene – and a necessary tool to grapple with the complexities of health in the rapidly changing landscape of the 21st century.” All of these changes in the field speak directly to the critical role of environmental context writ large in shaping bodies, biology, and health, and that to “situate” bodies and biology ethnographic grounding is necessary.
