William R. Leonard is Associate Professor of Anthropology at Northwestern University, Illinois. He is a biological anthropologist whose research focusses heavily on aspects of physiology, nutrition and health. He has extensive fieldwork experience in Siberia and Latin America examining how human populations adapt to extreme environments. Michael H. Crawford is Professor of Anthropology at the University of Kansas. His research focuses on anthropological genetics particularly in populations in the Americas. He has also written The Origins of Native Americans (1998), and edited Different Seasons: Biological Aging in Mennonites of Midwestern United States (2000).

Review of the hardback: '… this volume of high quality papers will be of most interest and reward to the specialists in nomadic pastoral societies who already have a lot of factual knowledge about these societies.' The Agricultural History Review
