Marlene Zuk on "Paleofantasy," her new book about what evolution really tells us

Dick Swanson talked Sept. 6 with Dr. Marlene Zuk, professor of ecology, evolution & behavior at the U of Minn., about her recent book, "Paleofantasy: What evolution really tells us about sex, diet, and how we live." The book addresses the belief that humans were at some point much healthier and more environmentally acclimated that we are today, shows how & why we're different from our ancestors, and lots more. A can't-put-it-down read, especially if you like science.
