RC and crew continue to introduce the conditions and difficulties for life and the planet during the Pleistocene-Holocene transition, and evaluate the extinction of the mega-mammals at the Younger-Dryas Boundary, bringing in 19th century scientific journal articles that spell out the findings and evaluations in direct terms – making it clear that the way the animals were killed and the sheer quantity of the remains puts the question beyond the possibility of human hunters and into the broad realm of global catastrophe.
