"An eye-opening look into why bodies work, or do not, the way they do. From blurry vision to crooked teeth, ACLs (anterior cruciate ligaments) that tear at alarming rates and spines that seem to spend a lifetime falling apart, it's surprising that human beings have beaten the odds as a species. Why do human mothers have such a life endangering experience giving birth? And why are there entire medical specialties for teeth and feet? In this funny, wide-ranging and often surprising book, biologist Alex Bezzerides tells listeners from where they inherited their adaptable, achy, brilliant bodies in the process of evolution."-- Amazon.
