What If: Science, Theory, and Possibilities episodes

What If Pangea Still Existed Today?

November 10, 2026•24 minutes

What would Earth look like if Pangea had never split apart? Explore an alternate world where today's continents remain one massive supercontinent, with mega-monsoons, a vast desert interior and a radically different path for evolution.

Meet Postosuchus, an ancient relative of crocodiles, and discover what Lystrosaurus fossils reveal about our planet's connected past. From continental drift and the Great Dying to cynodonts, the ancestors of mammals, explore the forces that shaped life on Earth—and whether humans could have evolved without them.
