In this episode, the massive, rapacious king power lizards of the Cretaceous are finally taken off the board by an asteroid. We trace the origins and progress of the skulking night vermin that are unleashed in their absence. These night vermin, with their whiskers and fur and fancy new brains, become the superpowers of the Cenozoic (our current era).

This is the story of the mammals, from a time long before their origin until the last common ancestor between humans and chimpanzees. 

Although this is a re-release of a previous episode, it contains never-before released material about the latest estimates of warm-bloodedness ariiving on the stage.
