Deloria (history, law, religious studies, political science, U. of Colorado-Boulder), author of the best-selling “Custer Died For Your Sins”, examines modern science as it relates to Native American oral history and exposes the myth of scientific fact, defending Indian accounts of natural history and population movement. He demonstrates how scientists manipulate data to fit their theories and documents traditional knowledge of Indian tribes in areas such as evolution, planetary history, the origin of humans, and natural disasters.
