What can we learn from paleofeces (a.k.a. dried ancient feces)? In this episode, we talk with archaeologist and paleoethnobotanist Dr. Kris Gremillion, and discuss her research with Native American plant remains in the caves and rock shelters of eastern Kentucky. She covers topics including: understanding the origins and development of agricultural systems, the challenges of working with plant remains, and how understanding ancient plants could help fight food insecurity in the future.
