Join hosts Hank Green, Kallie Moore, and Blake de Pastino as they 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.
Watched like two hours of YouTube autoplay.
Learned about “snowball earth” theory, and competing thoughts about whether it preceded or followed”the great unconformity” of several million missing years of rock layers in the Grand Canyon.
Also learned that the Mediterranean dried up at one point in the past which led to the formation of salt glaciers / formations.
