This fascinating read puts into examination the fantasy that we need to return to our ancestral hunter-gatherer diet, and in its extreme expression to a life-style of hunting, making our own tools and sprinting barefoot. Zuk, the author is a professor of ecology, evolution, and behavior at the University of Minnesota. In her multi-disciplinary analysis of a growing popular trend which argues that our bodies and behavior are out of synch with our modern lifestyles, Zuk using the latest scientific research debunks the notion that we have not evolved since “caveman days.” But this is no dry tome of the textbook variety but rather a lively, brilliant, and witty discussion of cutting edge science which shows that human evolution has continued along with that of all life on earth including bacteria and viruses.
The examples of how our genome has progressed come from the study of diseases we have, and the adaptability we possess to our changing environment. All in all it shows that survival is often a trade-off of one genetic change (mutation) that brings another sometimes less adaptive change with it, such as in the case of those who have immunity to cholera being more subject to the modern disease of cystic fibrosis.
So if you are curious about how our ancient ancestors lived, bred, cohabitated, and survived check this book out. Genetic research promises more fascinating information about how our body works and why we are subject to certain ailments and diseases.
