The Trials of Life

This is the third in Sir David Attenborough's epic Life series, following on from Life on Earth and The Living Planet. It begins with the ways in which animals arrive in the world and ends with the extraordinary techniques they employ to reproduce. In between, there are the other trials we all have to face: building a home, finding food, rearing children and getting on with friends and rivals.

Welcome to BBC EARTH! The world is an amazing place full of stories, beauty and natural wonder. Here you'll find 50 years worth of astounding, entertaining, thoughtprovoking and educational natural history content. Dramatic, rare, and exclusive, nature doesn't get more exciting than this.
