Population affinity estimation in forensic anthropology: a South African perspective

Forensic anthropologists face the complex task of estimating population affinity from skeletal remains, a process that involves inferring culturally constructed "social race" from biological tissues, a challenge further complicated by the nuanced distinction between population affinity and "race". The difficulty in making these estimations arises from the complex interplay between social constructs of race, skeletal morphology, and geographic origin. These factors are further influenced by elements such as assortative mating and institutional racism in regions such as South Africa and the United States. The interaction between cultural factors and biological traits raises the question of whether the challenges in estimating population affinity are inevitable or due to a limited understanding of human variation. To address this knowledge gap, this paper presents a review of population affinity estimation in forensic anthropology, with a focus on the South African context. It provides foundational background and historical insights, explores the medico-legal significance of population affinity, and critically evaluates both traditional and emerging estimation methods. By highlighting regional challenges and recent advancements, this review aims to enhance understanding and contribute to ongoing debates in the field. CLINICAL TRIAL NUMBER: Not applicable.
