How Our Stone Age Bodies Struggle To Stay Healthy In Modern Times

In The Story of the Human Body, evolutionary biologist Daniel Lieberman explains how our bodies haven't adapted to modern conditions. The result is "mismatch diseases" — ailments that occur because our bodies weren't designed for the environments in which we now live."If you got sick, you probably wouldn't go to an evolutionary biologist to get treated. But Daniel Lieberman, professor of evolutionary biology at Harvard University, says that his field can help you understand why you got sick, and make you more aware of healthy and harmful behaviors. Lieberman joins Fresh Air's Terry Gross to talk about some of the noninfectious diseases that may result from our Paleolithic bodies not being well-adapted to modern conditions. It's a list of ailments big and small, including acid reflux, acne, anxiety, asthma, certain cancers, depression, Type 2 diabetes, flat feet, high blood pressure, irritable bowel syndrome, lower back pain and osteoporosis. In his new book, The Story of the Human Body: Evolution, Health and Disease, Lieberman traces these troubles back to their origins."


A really interesting 35-minute segment that steps back from fads and looks at why we are sicker now than ever, despite being "modern" and "civilized."  Transcends worldviews, I'd wager... .
