Matt Cartmill writes, "In this clever, entertaining, and thoughtful book, Marks lays out some important limitations of science in general and genetics in particular. Using terms that everybody can understand, he demolishes the pretensions of scientists who try to use genetics to answer questions about the kinship of nations, the rights of animals, the racial identity of Kennewick Man, the hereditary Jewish priesthood, and the existence of God. Marks has a lot of fun with all this — and so will his readers." A member of NCSE, Marks teaches at the University of North Carolina at Charlotte.
