The concepts of "stress" and "health" are foundational in physical anthropology as guidelines for interpreting human behavior and biocultural adaptation in the past and present. Though related, stress and health are not coterminous, and while the term "health" encompasses some aspects of "stress," health refers to a more holistic condition beyond just physiological disruption, and is of considerable significance in contributing to anthropologists' understanding of humanity's lived experiences. Bioarchaeological interpretations of human health generally are made from datasets consisting of skeletal markers of stress, markers that result from (chronic) physiological disruption (e.g., porotic hyperostosis; linear enamel hypoplasia). Non-specific indicators of stress may measure episodes of stress and indicate that infection, disease, or nutritional deficiencies were present in a population, but in assessing these markers, bioarchaeologists are not measuring "health" in the same way as are human biologists, medical anthropologists, or primatologists. Rather than continue to diverge on separate (albeit parallel) trajectories, bioarchaeologists are advised to pursue interlinkages with other subfields within physical anthropology toward bridging "stress" and "health." The papers in this special symposium set include bioarchaeologists, human biologists, molecular anthropologists, and primatologists whose research develops this link between the concepts of "stress" and "health," encouraging new avenues for bioarchaeologists to consider and reconsider health in past human populations.

In 2009, Walker and colleagues questioned the validity of the iron‐deficiency anemia hypothesis as an explanatory mechanism for the presence of porotic hyperostosis (PH) and cribra orbitalia. They presented evidence demonstrating that iron deficiency inhibits, rather than promotes, marrow hypertrophy and argued a link between both PH and hemolytic or megaloblasic anemias (including vitamin B12 deficiency). This paper suggests that dismissing the iron‐deficiency anemia hypothesis may be premature, but, if dismissed, may result in unforeseen consequences. Vitamin B12 deficiency and iron deficiency often result from similar proximate causes, i.e. lack of animal protein in the diet and sanitation problems that lead to parasitic or diarrheal diseases, thereby promoting nutrient losses. As a result, vitamin B12 deficiency and iron deficiency commonly co‐occur. In individuals with a co‐occurrence of iron deficiency and vitamin B12 deficiency, a possible inhibition of marrow hypertrophy caused by iron deficiency may prevent the development of PH, despite the presence of (vitamin B12) nutritional deficiency. The implications of dismissing the iron‐deficiency anemia hypothesis are that many skeletal populations may exhibit hidden heterogeneity, i.e. individuals who are the most nutritionally stressed, with multiple nutrient deficiencies, would mimic the non‐stressed individuals and neither would show evidence of PH. However, the inclusion of multiple stress indicators and greater understanding of biocultural context in bioarchaeological analyses may mitigate the potential impacts of hidden heterogeneity in the expression of PH.

This article seeks to identify "Greeks" and "non-Greeks" in "mixed" mortuary contexts in a Greek colony. Specifically, we test the hypothesis that Illyrian and Greek individuals lived and were buried together at the Corinthian colony of Apollonia, Albania (established ca. 600 BC). The pattern of human biological interaction at Apollonia is tested by identifying variation in genetic relatedness using biodistance analysis of dental and cranial nonmetric traits for three sites: Apollonia (n = 116), its founder-city Corinth (n = 69), and Lofkënd (n = 108), an inland site near Apollonia pre-dating colonization. Logistic regression analysis estimates that individuals from colonial Apollonia are most closely related to prehistoric Illyrian populations (from Lofkënd and prehistoric Apollonia), rather than Greeks (from Corinth). The phenotypic similarity between colonial Apollonia and prehistoric Illyria suggests that there was a large Illyrian contribution to the gene pool at the colony of Apollonia. However, some trait combinations show low biological distances among all groups, suggesting homogeneity among Illyrian and Greek populations (assessed through pseudo-Mahalanobis' D(2) ). The degree of phenotypic similarity suggests shared ancestry and long-term migration throughout these regions. The impacts of missing data and small sample sizes are also considered.
