The Tie That Binds Us? Challenging the Primacy of DNA in Kinship Studies and Re-Centring Community in Defining Human Connections across Time

Abstract Biological determinism continues to shape how kinship is defined, from research to repatriation proceedings. This privileging of biological relatedness reflects and reinforces dominant ‘Western’ frameworks of kinship, often sidelining culturally-specific, Indigenous, and community-centered understandings of family and social belonging. Advances in archaeogenomic technologies today offer unprecedented insight into past human societies, and these advances have the potential to forge new, multivocal, and inclusive approaches to kinship. However, the application of ancient DNA risks reproducing power imbalances and epistemic hierarchies when genetic connections are assumed to be the primary or sole measure of social ties. This paper examines the conceptual and ethical implications of privileging DNA as a measure of kinship, emphasizing how such practices can obscure complex social realities, undermine self-determination, and reify narrow and essentialist understandings of identity. We call for critical reflection about the agents and motivations of archaeogenomics research, on the role of genetics in defining relationships and urge that multiple knowledge systems be considered in studies of kinship, both past and present.
