"In Race in North America, Audrey Smedley shows that "race" is a cultural invention that has been used variously and opportunistically since the eighteenth century. Race, in its origin, was not a product of science but of a folk ideology reflecting a new form of social stratification and a rationalization for inequality among the peoples of North America. New coauthor Brian Smedley joins Audrey Smedley in updating this renowned and groundbreaking text. The fourth edition includes a compelling new chapter on the health impacts of the racial worldview, as well as a thoroughly rewritten chapter that explores the election of Barack Obama and the evolving role of race in American political history. This edition also incorporates recent findings on the human genome and the implications of genomics. Drawing on new understandings of DNA expression, the authors scrutinize the positions of contemporary race scientists who maintain that race is a valid biological concept"--
