Recent critiques of ancient DNA (aDNA) studies in archaeology have called into question the problematic conflation of genetics with ethnic, cultural and racial identity. As yet, however, there has been little discussion of the increasing use of aDNA to reconstruct prehistoric kinship systems. This article draws on anthropological research to argue that kinship relations are not determined by biogenetic links, but are generated through social practice. A variety of archaeological evidence can be employed to explore how enduring affective relationships are created with both human and non-human others. These points require us to challenge androcentric and heteronormative interpretations of aDNA data in the Bronze Age and more widely.
