The Story of the Human Body

Daniel Lieberman explains how the human body evolved over millions of years and why our current environment often clashes with our biological heritage. He details the transition from bipedalism and long-distance running to the development of calorie-dense diets and sedentary lifestyles. The central focus is the concept of dysevolution: the emergence of chronic ailments like type 2 diabetes, heart disease, and lower back pain. These conditions persist because we live in a world for which our Paleolithic bodies were not built, creating a mismatch between ancient genes and modern culture.

This book is intended for students of evolutionary biology and readers interested in the anatomical origins of health and disease. It provides a scientific framework for understanding how physical activity and nutrition affect the skeletal and metabolic systems. Readers gain a technical perspective on why modern medical treatments often address symptoms rather than the evolutionary causes of illness. By the end, the reader possesses a roadmap for aligning modern habits with biological requirements to mitigate the effects of mismatch diseases.
