Joining the ranks of modern myth busters, Dr. Sharon Moalem turns our current understanding of illness on its head and challenges us to fundamentally change the way we think about our bodies, our health, and our relationship to just about every other living thing on earth. Through a fresh and engaging examination of our evolutionary history, Dr. Moalem reveals how many of the conditions that are diseases today actually gave our ancestors a leg up in the survival sweepstakes. But Survival of the Sickest doesn’t stop there. It goes on to demonstrate just how little modern medicine really understands about human health, and offers a new way of thinking that can help all of us live longer, healthier lives.
Moalem, a medical student with a Ph.D. in neurogenetics, asks a number of provocative questions, such as why debilitating hereditary diseases persist in humans and why we suffer from the consequences of aging. His approach to these questions is solidly rooted in evolutionary theory, and he capably demonstrates that each disease confers a selective advantage to individuals who carry either one or two alleles for inherited diseases. But very little is new; the principles, if not every particular, that Moalem addresses have been covered in Randolph Nesse and George Williams’s Why We Get Sick, among others. Whether he is discussing hemochromatosis (a disorder that causes massive amounts of iron to accumulate in individuals), diabetes or sickle cell anemia, his conclusion is always the same: each condition offers enough positive evolutionary advantages to offset the negative consequences, and this message is repeated over and over. Additionally, Moalem’s endless puns and simple jokes wear thin, but his light style makes for easy reading for readers new to this subject. ~ Publisher Weekly
