Forty-seven percent of the American people, according to a 1991 Gallup poll, believe that God made man as man is now in a single act of creation, and within the last ten thousand years. Ronald L. Numbers chronicles the astonishing resurgence of this belief since the 1960s, as well as the creationist movement's tangled roots in the theologies of late nineteenth- and early twentieth-century Baptists, Presbyterians, Lutherans, Adventists, and other religious groups.

Even more remarkable than Numbers's story of today's widespread rejection of the theory of evolution is the dramatic shift from acceptance of the earth's antiquity to the insistence of present-day scientific creationists that most fossils date back to Noah's flood and its aftermath, and that the earth itself is not more than ten thousand years old. Numbers traces the evolution of scientific creationism and shows how the creationist movement challenges the very meaning of science.
