From ancient seas to fertile soils, evolutionary biologist Shane Campbell-Staton explores the remarkable journey that transformed the Cretaceous coastline into the fertile "Black Belt" region of the American South. He joins oceanographer Craig McClain, Professor Sven Beckert, and geneticist Steven Micheletti to uncover how millions of years of deposits shaped events in Black American history.

Human Footprint explores the impact of humans on the planet. Join Shane as he travels from farms to restaurants, from high-tech labs to street markets, and from forests to cities to uncover the consequences of our unique human history. Are you ready to explore our past, present and future as a species?
