Author of The Story of the Human Body (https://amzn.to/39q3bvi) and most recently Exercised: Why Something We Never Evolved to Do Is Healthy and Rewarding (https://amzn.to/2Pchhda), Dr Daniel Lieberman is a paleoanthropologist and Professor of Human Evolutionary Biology at Harvard University. He has studied the evolution of the human head, but his main focus is currently on the evolution of the human physical activity. He has lived with cultures, all over the globe, to explain the science of how and why we move today. Research specifically related to activities such as walking, running as well as changes to our body’s environments can help prevent injuries and treat musculoskeletal diseases.
