The story of the human body: evolution, health and disease

This book explores how the way we use our bodies is all wrong.

From an evolutionary perspective, if normal is defined as what most people have done for millions of years, then it's normal to walk and run 9-15 kilometers a day to hunt and gather fresh food which is high in fibre, low in sugar, and barely processed.

It's also normal to spend much of your time nursing, napping, making stone tools, and gossiping with a small band of people.

Our 21st-century lifestyles, argues Dan Lieberman, are out of synch with our stone-age bodies.

Never have we been so healthy and long-lived - but never, too, have we been so prone to a slew of problems that were, until recently, rare or unknown, from asthma, to diabetes, to - scariest of all - overpopulation.

This book asks how our bodies got to be the way they are, and considers how that evolutionary history can help us evaluate how we use our bodies.
