Our genetic markers have come to be regarded as portals to the past. Analysis of these markers is increasingly used to tell the story of human migration; to investigate and judge issues of social membership and kinship; to rewrite history and collective memory; to right past wrongs and to arbitrate legal claims and human rights controversies; and to open new thinking about health and well-being. At the same time, in many societies genetic evidence is being called upon to perform a kind of racially charged cultural work: to repair the racial past and to transform scholarly and popular opinion about the “nature” of identity in the present.

Genetics and the Unsettled Past considers the alignment of genetic science with commercial genealogy, with legal and forensic developments, and with pharmaceutical innovation to examine how these trends lend renewed authority to biological understandings of race and history.

This unique collection brings together scholars from a wide range of disciplines—biology, history, cultural studies, law, medicine, anthropology, ethnic studies, sociology—to explore the emerging and often contested connections among race, DNA, and history. Written for a general audience, the book’s essays touch upon a variety of topics, including the rise and implications of DNA in genealogy, law, and other fields; the cultural and political uses and misuses of genetic information; the way in which DNA testing is reshaping understandings of group identity for French Canadians, Native Americans, South Africans, and many others within and across cultural and national boundaries; and the sweeping implications of genetics for society today.

How has DNA come to be seen as a cosmic truth, representative of all life, potential for all cures, repository for all identity, and end to all stories? In The Poetics of DNA, Judith Roof examines the rise of this powerful symbol and the implications of its ascendancy for the ways we think—about ourselves, about one another, and about the universe.

Descriptions of DNA, Roof argues, have distorted ideas and transformed nucleic acid into the answer to all questions of life. This hyperbolized notion of DNA, inevitably confused or conflated with the “gene,” has become a vector through which older ways of thinking can merge with the new, advancing long-discredited and insidious ideas about such things as eugenics and racial selection and influencing contemporary debates, particularly the popular press obsession with the “gay gene.” Through metaphors of DNA, she contends, racist and homophobic ideology is masked as progressive science.

Grappling with twentieth-century intellectual movements as well as contemporary societal anxieties, The Poetics of DNA reveals how descriptions of DNA and genes typify a larger set of epistemological battles that play out not only through the assumptions associated with DNA but also through less evident methods of magical thinking, reductionism, and pseudoscience.

For the first time, Roof exposes the ideology and cultural consequences of DNA and gene metaphors to uncover how, ultimately, they are paradigms used to recreate prejudices.

Judith Roof is professor of English and film studies at Michigan State University. She is the author of several books, including All about Thelma and Eve: Sidekicks and Third Wheels.
