A growing number of forensic researchers are questioning how the field interprets the geographic ancestry of human remains.

Racial reckonings were happening everywhere in the summer of 2020, after George Floyd was killed in Minneapolis by the police. The time felt right, two forensic anthropologists reasoned, to reignite a conversation about the role of race in their own field, where specialists help solve crimes by analyzing skeletons to determine who those people were and how they died.

Dr. Elizabeth DiGangi of Binghamton University and Jonathan Bethard of the University of South Florida published a letter in The Journal of Forensic Science that questioned the longstanding practice of estimating ancestry, or a person’s geographic origin, as a proxy for estimating race. Ancestry, along with height, age at death and assigned sex, is one of the key details that many forensic anthropologists try to determine.

That fall, they published a longer paper with a more ambitious call to action: “We urge all forensic anthropologists to abolish the practice of ancestry estimation.”

In recent years, a growing number of forensic anthropologists have grown critical of ancestry estimation and want to replace it with something more nuanced…

Study: Let’s Replace ‘Ancestry’ in Forensics With Something More Accurate

Study: Let’s Replace ‘Ancestry’ in Forensics With Something More Accurate

A new study finds forensics researchers use terms related to ancestry and race in inconsistent ways, and calls for the discipline to adopt a new approach to better account for both the fluidity of populations and how historical events have shaped our skeletal characteristics.

Forensic anthropology is a science, and we need to use terms consistently,” says Ann Ross, corresponding author of the study and a professor of biological sciences at North Carolina State University. “Our study both highlights our discipline’s challenges in discussing issues of ancestral origin consistently, and suggests that focusing on population affinity would be a way forward.”

Race is a social construct – there’s no scientific basis for it. Population affinity, in the context of forensic anthropology, is determined by the skeletal characteristics associated with groups of people. Those characteristics are shaped by historic events and forces such as gene flow, migration, and so on. What’s more, these population groups can be very fluid…

Simple Summary

Within the practice of forensic anthropology ancestry is oftentimes used as a proxy for social race. This concept and its implications were explored via a content analysis (2009–2019) of the Journal of Forensic Sciences. Our findings revealed antiquated views of race based on the trifecta of continental populations (Asia, Europe, and Africa) continue to be pervasive in the field despite scientific invalidation of the concept of race decades earlier. Moreover, our employment of modern geometric morphometric and spatial analysis methods on craniofacial coordinate anatomical landmarks from several Latin American samples produced results in which the groups were not patterned by ancestry trifecta. Based on our findings we propose replacing the assumption of continental ancestry with a population structure approach that combines microevolutionary and cultural factors with historical events in the examination of population affinity.

Abstract

One of the parameters forensic anthropologists have traditionally estimated is ancestry, which is used in the United States as a proxy for social race. Its use is controversial because the biological race concept was debunked by scientists decades ago. However, many forensic anthropologists contend, in part, that because social race categories used by law enforcement can be predicted by cranial variation, ancestry remains a necessary parameter for estimation. Here, we use content analysis of the Journal of Forensic Sciences for the period 2009–2019 to demonstrate the use of various nomenclature and resultant confusion in ancestry estimation studies, and as a mechanism to discuss how forensic anthropologists have eschewed a human variation approach to studying human morphological differences in favor of a simplistic and debunked typological one. Further, we employ modern geometric morphometric and spatial analysis methods on craniofacial coordinate anatomical landmarks from several Latin American samples to test the validity of applying the antiquated tri-continental approach to ancestry (i.e., African, Asian, European). Our results indicate groups are not patterned by the ancestry trifecta. These findings illustrate the benefit and necessity of embracing studies that employ population structure models to better understand human variation and the historical factors that have influenced it.
