Gregory Retallack

Gregory Retallack, a Professor Emeritus in Earth Sciences at the University of Oregon, dives deep into paleopedology—the study of ancient soils. He discusses how analyzing fossil soils reveals Earth's climatic history and informs our understanding of life’s coevolution with soil. Retallack also explores the biological markers of life found in geological records and the connection between ancient soils and modern climate challenges. Plus, the fascinating relationship between soil types and the flavors in wine adds a delicious twist to the conversation.
