Walking with Beasts

Walking with Beasts is a six-part BBC series chronicling the evolution of mammals after the extinction of the dinosaurs 65 million years ago. Narrated by Kenneth Branagh, it spans the entire planet and explores various branches of the mammalian kingdom.

The series begins with mammals rising to dominance after a cataclysmic environmental event caused the extinction of the dinosaurs. Inheriting the Earth, mammals evolved from small, squirrel-like creatures into some of the largest animals ever to inhabit the planet. From there, the series travels across the globe, diving into the deepest oceans to follow huge predators such as Basilosaurus, which lurked in the depths. It also follows the struggles of a rhinoceros calf, examines the day-to-day life of early hominins, and explores the challenges faced by animals during the last Ice Age.

Covering the period from the Paleogene through to the Neogene, Walking with Beasts focuses on the evolution of prehistoric mammals into the whales, horses, and humans that inhabit the planet today.

The series is a sequel to Walking with Dinosaurs.
