Survival of the Sickest: A Medical Maverick Discovers Why We Need Disease

Science News,  August 4, 2007  

SURVIVAL OF THE SICKEST: A Medical Maverick Discovers Why We Need Disease. SHARON MOALEM

Can sunbathing reduce cholesterol levels? Did diabetes help humans survive the ice age? Moalem investigates these questions and others surrounding common illnesses. He explains why many diseases that plague us today, including sickle-cell anemia and hemochromatosis, actually helped our ancestors survive. He explores whether our DNA can be changed by our environment. Readers learn how certain microbes can affect human behavior and how a woman's diet in early pregnancy can affect her child's weight. The author also delves into a controversial theory that humans were once aquatic animals. Moalem provides an unorthodox take on disease. Morrow, 2007, 267 p., hardcover, $25.95.
