Eons is a show produced in collaboration with PBS Digital Studios wherein Hank Green, Kallie Moore, and Blake de Pastino take you on a journey through the history of life on Earth. From the dawn of life in the Archaean Eon through the Mesozoic Era — the so-called “Age of Dinosaurs” -- right up to the end of the most recent Ice Age.
