Chimerism, Mosaicism and the Cultural Construction of Kinship

Abstract

This article introduces chimerism and mosaicism as two recent scientific ‘discoveries’ that present challenges to western heteronormative notions of kinship. Chimerism, in the form of xenotransplantation, already demands a rethinking of traditional boundaries between what is considered ‘kin’ and ‘non-kin’. Recent biological studies describing chimerism as two genetically distinct cell lines in one organism not caused by transplantation, invites further questions regarding the stability of kinship ideology. The aim of the article is to argue, with anthropologists and feminist science studies scholars, that the western understanding of kinship relies upon a problematic use of ‘nature’, and that this dependence necessarily produces shifting and contradictory definitions of kinship.
