As genetic knowledge continues to strengthen notions of identity in Euro-American societies and beyond, epigenetic knowledge is intervening in these legitimation frameworks. I explore these interventions in the realm of assisted reproduction—including adoption, donor conception, and gestational surrogacy. The right to identity is protected legally in many states and receives due attention in public and private international law. Originating from the context of adoption, donor-conceived and surrogacy-born persons have recently demanded the same protections and focused on the right to genetic (...) knowledge. This article explores possible implications of epigenetic knowledge on identity. I start by articulating the deep influence of genetics on the notion of identity, and how this unfolds in legal contexts. Next, I examine how epigenetic findings that stress the importance of seeing biological life as situated and embedded in environments can challenge how adoption, donor conception, and gestational surrogacy are experienced and understood. While I argue that epigenetic knowledge can reify identity with the same determinism underpinning genetics, it can also allow for more biosocial understandings of identity that consider history and experience as entangled with biology.

In this Introduction, we present a collection of articles under the topic “the reproductive bodies of postgenomics.” Through individual and collective research, the articles explore—sociologically, ethnographically, and philosophically—how bioscience in the postgenomic age is changing our understanding of reproductive bodies, and more broadly, how it is challenging existing ideas of heredity, embodiment, kinship, and identity. Feminist and postcolonial theories of technoscience are at the heart of this collection, and our aim is to further biosocial thinking while being cognizant that practices (...) of postgenomics also continue to reproduce deterministic paradigms. The concepts of “knowledge,” “experience,” and “justice” form the reference points animating our investigations. We bring these concepts into conversation with one another to disentangle how postgenomics operate differently on the reproductive body, namely on the levels of practice, discourse, and norms. This is an important exercise as it will enable social science and humanities scholars to evaluate the political capacities of postgenomics for the future study of reproduction. (shrink)
