This review article seeks to analyze the main contributions of historical research and, to a lesser extent, sociology and anthropology, over the last twenty years in three distinct but closely interwoven domains: the history of eugenics, the history of heredity, and the history of the biological notion of race. After clarifying the relations between these too-often conflated subjects, the article compares the evolution of their respective fields of research, distinguishing between the development of previously addressed themes and the exploration of new perspectives. It considers historiographical reflections on eugenicist policies of forced sterilization, on the close relations established between eugenics and natalism in certain countries such as France, and on the genealogy of the category of race and mechanisms for objectifying racial diversity. The profound renewal of the three domains of research over the period is analyzed via two complementary perspectives: the significant broadening of their geographical horizons and the reproblematization of their scientific objects. Though the focus of earlier work on the European and North-American experience may have suggested that biopolitics, eugenics, and “scientific racism” were the prerogative of Western countries, the recent increase in studies of Latin America, Asia, and, to a lesser extent, the Middle East and Africa, has definitively discredited this reductive vision. In parallel, a better awareness of gender perspectives, the exploration of historical continuities between eugenics and medical genetics, and the reevaluation of the role of biomedicine in debates on human heredity and the notion of race have profoundly renewed the three fields of research studied here.
