In this episode we unpack the mysteries of how life evolved in North America. From massive volcanic eruptions, that killed three quarters of all species, to the appearance of giant inland seas populated by huge marine dinosaurs, the geology and life of North America have always gone hand in hand. We also reveal the part that geology played in the arrival of humans on the continent, as the appearance of the Panamanian land bridge altered ocean currents, helping bring about the last ice age.
