The Maternal Imprint

Leading gender and science scholar Sarah S. Richardson charts the untold history of the idea that a woman's health and behavior during pregnancy can have long-term effects on her descendants' health and welfare. The idea that a woman may leave a biological trace on her gestating offspring has long been a commonplace folk intuition and a matter of scientific intrigue, but the form of that idea has changed dramatically over time. Beginning with the advent of modern genetics at the turn of the twentieth century, biomedical scientists dismissed any notion that a motherexcept in cases of extreme deprivation or injurycould alter her offsprings traits. Consensus asserted that a childs fate was set by a combination of its genes and post-birth upbringing. Over the last fifty years, however, this consensus was dismantled, and today, research on the intrauterine environment and its effects on the fetus is emerging as a robust program of study in medicine, public health, psychology, evolutionary biology, and genomics. Collectively, these sciences argue that a womans experiences, behaviors, and physiology can have life-altering effects on offspring development. Tracing a genealogy of ideas about heredity and maternal-fetal effects, this book offers a critical analysis of conceptual and ethical issuesin particular, the staggering implications for maternal well-being and reproductive autonomyprovoked by the striking rise of epigenetics and fetal origins science in postgenomic biology today.
