Sir David Attenborough reveals how Mammals have conquered the Earth, uncovering the secrets to their success with their winning design, incredible adaptability, unrivalled intelligence, and unique sociability.

66 million years ago, when the reign of the dinosaurs came to an end, mammals were set free to exploit every corner of the planet. Mammals reveals the strategies, behaviours and traits that lie behind the astonishing success of this remarkable group of animals. Above all, the series celebrates the amazing intelligence that enables mammals to learn, remember, problem-solve, parent, and co-operate.

In six episodes we will show how mammals have taken advantage of every major environment on earth. They are found in every ocean, and on every continent, from frozen wildernesses, dense jungles, baking deserts, even the dark depths of the open ocean and the skies above our forests.
