Brilliantly and provocatively, The Remnants of Race Science reveals that the so-called decline of racial thought in human biology was really just a substitution of other more flexible ideas of human differencemostly from the Global Southfor the rigid racist typologies of the Global North. This more inclusive refiguring of racial difference would make possible the economic development of people once excluded from modernitywhich meant in practice their neocolonial incorporation into the netherworlds of global capitalism. In this paradigm-shifting book, Gil-Riańo thus offers us a new southern vocabulary to talk about racism and antiracism. -- Warwick Anderson, author of Colonial Pathologies: American Tropical Medicine, Race, and Hygiene in the Philippines Starting with scientific research from the Southern Hemisphere, this important book overturns the common story of antiracist science as simplistically rooted in rejecting fixed biological kinds. Drawing from a transnational archive, Gil-Riańo shows how so-called anti-racist science was caught up in projects of improvement that rested on a multitude of other racisms. -- M. Murphy, author of The Economization of Life Latin Americanists have long maintained that race and biology are shaped by culture, social organization, and economic conditions. In this deeply researched study, Gil-Riańo shows how Latin American racial ideas shaped the postWorld War II human sciences and UNESCO projects. The human sciences did not renounce racial explanationas so many believebut folded them into global ideas about economic development. -- Karin Rosemblatt, author of The Science and Politics of Race in Mexico and the United States, 1910-1950 Offers useful historical context to current debates about how to successfully build solidarity in science and society. * Science * An important and timely contribution to the social sciences that any scholar interested in these fields, their history, or antiracism ought to seek out. * Journal of Anthropological Research * An intellectual historyand a brilliant one at thatwhich provides a fresh, complex, and compelling perspective on UNESCO. -- Michelle Brattain, Georgia State University * American Historical Review *
