The Asteroid Survivors: How Mammals Inherited the Earth

When the asteroid wiped out the dinosaurs 66 million years ago, the biggest mammal in one Colorado valley weighed about a pound. Within about 40 million years, the survivors' descendants had become whales, bats, giants heavier than several elephants and the first apes. This documentary follows the Paleogene, the 43 million years after the asteroid, from inside the world the survivors inherited. Stand in the darkness that followed the impact, then in a Colombian rainforest where the largest snake ever found hunted. Walk a swamp forest near the North Pole through four months of night, watch a pregnant mare sink into a German crater lake, and see the first whales walk into the sea. The whole journey answers one question: how did a few small survivors inherit the planet so quickly?
