Introduction

I interview award-winning astrobiologist and science writer Lewis Dartnell. We discuss themes from his most recent book, Origins: How The Earth Made Us, as well as ideas from his field of study, astrobiology. Dr. Dartnell holds the Professorship in Science Communication at the University of Westminster. Interview topics include: how the Earth's cycles may have driven human evolution, humanity's search for extraterrestrial life, the shadow biosphere, why some civilizations came to dominate the globe, and more.
