Time to worry again—our lifestyle choices do impact our genetic code and that of our children (and even grandchildren!). "The potential is staggering. . . . The age of epigenetics has arrived."—Time, January 2010 Epigenetic means "on the gene," and the term refers to the recent discovery that stress in the environment can impact an individual's physiology so deeply that those biological scars are actually inherited by the next several generations. For instance, a recent study has shown that men who started smoking before puberty caused their sons to have significantly higher rates of obesity. And obesity is just the tip of the iceberg—many researchers believe that epigenetics holds the key to understanding cancer, Alzheimer's, schizophrenia, autism, and diabetes. Epigenetics is the first book for general readers on this fascinating and important topic. The book is driven by stories such as the Dutch famine of World War II, José Canseco and steroids, the breeding of mules and hinnies, Tazmanian devils and contagious cancer, and more. Reviews: Epigenetics explains all this in clear, no-nonsense prose. . . . One particularly excellent chapter explains epigenetic change through the body of steroid-addled baseball player José Canseco, from his brain to his testicles. —Josh Rothman, Boston Globe Francis’s primer introduces a new field. It’s a thorough guide to the many ways in which personality and health can play out through our genes but not be coded for in DNA.—Christine Kenneally, Slate About the Author: Richard C. Francis is a science journalist with a PhD in neurobiology from Stony Brook University. He is the author of the acclaimed books Domesticated, Epigenetics, and Why Men Won’t Ask for Directions. |
