Department of Anthropology Ph.D. student Kelly Kamnikar and assistant professor Dr. Joe Hefner recently published a chapter in Avances en Antropología Forense. This chapter reviews population affinity estimation using macromorphoscopic trait analysis. The authors focus on the application of this method to Latin American groups and discuss refining broad categories used in population affinity estimation, like Hispanic. They aim to provide a starting point for investigation into biological distance and population affinity for practitioners working with Latin American populations to improve methodology used in identification of migrant remains at the Mexico-US border, and victims of violence that may occur in transit from one country to another.
