Abstract
The 1943 Battle of Tarawa resulted in the loss of approximately 1000 U.S. service members on or around Betio Island, Tarawa Atoll, Republic of Kiribati. Nearly half the casualties were accounted for following the battle. The Defense POW/MIA Accounting Agency (DPAA) has worked to identify the remaining ~510 unaccounted-for service members, with successful identification of ~160 service members to date. Demographic data pulled from historical documentation of the U.S. losses indicate a relatively homogeneous population (99% White, 81% between the ages of 17 to 23 years, and only two individuals documented with a religious preference other than Protestant or Catholic). Using this demographic data as a framework, three case studies are presented to demonstrate how a holistic biosocial approach to identity building could facilitate forensic identifications. The temporal and sociocultural contextualization of analyses enables anthropologists to navigate the inconsistencies between 21st century and historical (1940s) social identity concepts and overcome challenges to identification. The case studies demonstrate how biological evidence, genetic evidence, and material culture (material evidence) differently contribute to the social identity of an individual and can impact identification efforts when analytical conclusions are incongruent with historical documentation. The first case examines how morphometric biological affinity assessments are biased by the fluidity of social identity concepts when complex morphological and metric indicators of biological affinity are not represented in the historical race categories for the U.S. Battle of Tarawa casualties. The second case demonstrates how biogeographic genetic affinity predictions, through a discussion of the G2a4 haplogroup, need to be examined holistically in the context of other lines of evidence. The third case highlights how material evidence can further define social identity beyond physicality, genetic structure, and race. The challenges of interpreting identity from human remains, as highlighted through these examples, are common among anthropologists working in disaster victim identification and other humanitarian contexts. Thus, it is imperative for anthropologists to be self-aware of implicit biases toward the current prevailing definitions of biological and social identity and to consider historical perceptions of identity when working in these contexts.
