The (Mis)appropriation of Biological Anthropology in Race Science and the Implications for Forensic Anthropology

Most biological anthropologists acknowledge that phenotypic human variation is distinct from human race. However, there is the potential for the research on human variation to be (mis)interpreted by the public as a reification of biological races. To explore this possible misuse, this study is a content analysis of articles (n = 1146) in the prominent race science journals Mankind Quarterly; The Journal of Social, Political, and Economic Studies; and The Occidental Quarterly. The goal is to investigate how race science employs research in biological and forensic anthropology to justify arguments. Articles were evaluated according to country affiliation, discipline, data sets, racial/ethnic terminology, position on racial hierarchy, position on racial segregation and eugenics, focus of study, views of scientific community, and the average power index (PI). Additionally, specific examples of (mis)appropriation are highlighted. Though the primary discipline represented in these publications is psychology, biological anthropology maintains a presence. Skeletal and dental traits, genetics, and paleoanthropological data are used to argue for biological racial differences and taxonomic distinctions. The research of forensic ancestry estimation was regularly used to legitimize the concept of biological race. While the PIs of the articles are low, they are present on the internet and circulate within social media. The continued use of biological anthropology to reinforce racial essentialism should force practitioners to question the ethical implications of their research. Finally, we provide discussion regarding shiftsin methodology and terminology to address how biological and forensic anthropologists can rectify the damage this research may directly and indirectly cause.

On WEIRD Anthropologists and Their White Skeletons

Most forensic anthropologists and the populations they study are WEIRD—that is, Western, educated, industrialized, rich, and democratic. In their interventions into the WEIRD, Clancy and Davis (2019) contend that WEIRD is a euphemism for white and that it is the white, Western European–derived scientists and subjects that skew the predominating narrative of the human condition. While they demonstrate how biological anthropology can decenter the WEIRD, it is fruitful to extend their framework specifically to forensic anthropology. We argue that the scientific enterprise of forensic anthropology is unique in that: (1) it is touted as an objective tool that must operate within medicolegal systems, (2) it involves board certification and accreditation standards, and (3) it holds ancestry and race as core to its practice. In a bibliometric survey of journal articles over the past five years (n = 793), we find that up to 79% of authors originate from WEIRD contexts. In articles specifically studying ancestry, European-derived populations are included 88% of the time as a category for comparison to other groups, while only 12% do not include Europeans. Furthermore, 49% of articles unrelated to ancestry use white subjects solely or in part, reinforcing a historic tendency to measure all human variation against one particular norm. We also find that WEIRD articles receive significantly more recognition than non-WEIRD counterparts. In this reflexive and positional exercise, we hope to make visible how whiteness as WEIRDness informs the history, values, and practices of forensic anthropology on a global scale.

Sex Estimation Using Geometric Morphometrics

Creating and testing efficient techniques for the sex estimation of modern human skeletal remains has been a significant focus in biological anthropology. It is well established that the innominate, particularly the pubic bone, is a sexually dimorphic part of the human skeleton, but prone to fragmentation. Using modern pubic bones of known age and sex, this study aims to capture shape differences using geometric morphometrics (GMM) to test classification accuracy of segments of the pubic bone. The sample consists of 70 left adult pubic bones from the William M. Bass Donated Skeletal Collection, with 35 males and 35 females of mixed age and population affinity. Landmarks were placed on the dorsal surface of the pubic body and ischiopubic ramus to capture their overall shape in two dimensions, so the study is easily replicable and applicable. The scans were separately run through a generalized Procrustes, principal components (PCA), and canonical linear discriminant function analysis (DFA). The DFA results show high classification accuracy for the pubic body (94% males, 100% females) and the ischiopubic ramus (100% females, 97% males), with the PCA DFA allowing a researcher to explore specific shape changes driving the differentiation between groups. GMM was able to quantify and successfully discriminant the shape changes between males and females for small elements of the pubis, which can be applied to fragmentary remains and future morphological methods.

Morphometric Maps of Bilateral Asymmetry in the Human Humerus: An Implementation in the R Package Morphomap

In biological anthropology, parameters relating to cross-sectional geometry are calculated in paired long bones to evaluate the degree of lateralization of anatomy and, by inference, function. Here, we describe a novel approach, newly added to the morphomap R package, to assess the lateralization of the distribution of cortical bone along the entire diaphysis. The sample comprises paired long bones belonging to 51 individuals (10 females and 41 males) from The New Mexico Decedent Image Database with known biological profile, occupational and loading histories. Both males and females show a pattern of right lateralization. In addition, males are more lateralized than females, whereas there is not a significant association between lateralization with occupation and loading history. Body weight, height and long-bone length are the major factors driving the emergence of asymmetry in the humerus, while interestingly, the degree of lateralization decreases in the oldest individuals.
