We may have health monitors and fitness trackers, but could it be the case that even with this technology, humans are actually reversing evolutionary progress?

Dr Lieberman is the Chair of the Department of Human Evolutionary Biology at Harvard University. His research focuses on how the human body has evolved to be the way it is, he also explores how humans evolved to run long distances to scavenge and hunt. He is the author of the best-selling books, ‘The Story of the Human Body: Evolution, Health, and Disease’ and ‘Exercised: Why Something We Never Evolved to Do Is Healthy and Rewarding’.

In this conversation Daniel and Steven discuss topics, such as if human evolution is going backwards, why veganism is not the answer, how commuting is making you fat and what we can learn from hunter-gatherers.
