In a deep dark underwater cave, Mexican divers in 2007 found a mountain of prehistoric animal bones…and one human skeleton. It was Naia– the oldest skeleton ever discovered in the Americas. What can her bones tell us about our human origins? And more than that, what do they tell us about what it means to be human? Come with us on location to Dos Palmas cenote in Mexico, as Katie interviews returning guest Gabo Cemé.

Music featured in this episode by Kevin McLeod, ELPHNT, Jimena Contreras, Patrick Patrikios, and Amulets.
