Is inbreeding harmful? Are human beings and other primates naturally inclined to mate with their closest relatives? Why is incest widely prohibited? Why does the scope of the prohibition vary from society to society? Why does incest occur despite the prohibition? What are the consequences? After one hundred years of intense argument, a broad consensus has emerged on the first two questions, but the debate over the others continues. That there is a biological basis for the avoidance of inbreeding seems incontrovertible, but just how injurious inbreeding really is for successive generations remains an open question. Nor has there been any conclusion to the debate over Freud’s view that the incest taboo is necessary because humans are sexually attracted to their closest relatives—a claim countered by Westermarck's argument for the sexually inhibiting effects of early childhood association. This book brings together contributions from the fields of genetics, behavioral biology, primatology, biological and social anthropology, philosophy, and psychiatry which reexamine these questions.

In 1951, the geneticist Luigi Luca Cavalli-Sforza was teaching in Parma when a student--a priest named Antonio Moroni--told him about rich church records of demography and marriages between relatives. After convincing the Church to open its records, Cavalli-Sforza, Moroni, and Gianna Zei embarked on a landmark study that would last fifty years and cover all of Italy. This book assembles and analyzes the team's research for the first time. Using blood testing as well as church records, the team investigated the frequency of consanguineous marriages and its use for estimating inbreeding and studying the relations between inbreeding and drift. They tested the importance of random genetic drift by studying population structure through demography of the last three centuries, using it to predict the spatial variation of frequencies of genetic markers. The authors find that drift-related genetic variation, including its stabilization by migration, is best predicted by computer simulation. They also analyze the usefulness and limits of the concept of deme for defining Mendelian populations. The genetic effect of consanguineous marriage on recessive genetic diseases and for the detection of dominance in metric characters are also studied. Ultimately bringing together the many strands of their massive project, Cavalli-Sforza, Moroni, and Zei are able to map genetic drift in all of Italy's approximately 8,000 communes and to demonstrate the relationship between each locality's drift and various ecological and demographic factors. In terms of both methods and findings, their accomplishment is tremendously important for understanding human social structure and the genetic effects of drift and inbreeding.

An essential guide to this major contemporary issue, Consanguinity in Context is a uniquely comprehensive account of intra-familial marriage. Detailed information on past and present religious, social and legal practices and prohibitions is presented as a backdrop to the preferences and beliefs of the 1100+ million people in consanguineous unions. Chapters on population genetics, and the role of consanguinity in reproductive behaviour and genetic variation, set the scene for critical analyses of the influence of consanguinity on health in the early years of life. The discussion on consanguinity and disorders of adulthood is the first review of its kind and is particularly relevant given the ageing of the global population. Incest is treated as a separate issue, with historical and present-day examples examined. The final three chapters deal in detail with practical issues, including genetic testing, education and counselling, national and international legislation and imperatives, and the future of consanguineous marriage worldwide.

Like many gentlemen of his time, Charles Darwin married his first cousin. In fact, marriages between close relatives were commonplace in nineteenth-century England, and Adam Kuper argues that they played a crucial role in the rise of the bourgeoisie. This groundbreaking study brings out the connection between private lives, public fortunes, and the history of imperial Britain.
