Earth teems with a staggering variety of animals, including 9,000 kinds of birds, 28,000 types of fish, and more than 350,000 species of beetles. What explains this explosion of living creatures—1.4 million different species discovered so far, with perhaps another 50 million to go? The source of life's endless forms was a profound mystery until Charles Darwin brought forth his revolutionary idea of natural selection. But Darwin's radical insights raised as many questions as they answered. What actually drives evolution and turns one species into another? To what degree do different animals rely on the same genetic toolkit? And how did we evolve?

An astonishing journey revealing the awesome power of the natural world. Over the course of one single day, we track the sun from the highest mountains to the remotest islands to exotic jungles.

Laika, a stray dog, was the first living being to be sent into space and thus to a certain death. A legend says that she returned to Earth as a ghost and still roams the streets of Moscow alongside her free-drifting descendants. While shooting this film, the directors little by little realised that they knew the street dogs only as part of our human world; they have never looked at humans as a part of the dogs’ world.

The Siberian discovery of the best-preserved woolly mammoth on record has teams of experts working around the globe, and around the clock, on some of the most ambitious projects in science. In Russia, paleontologists are conducting a historic autopsy on the 40,000-year-old beast to find out how it lived, and how it died. Meanwhile labs in South Korea and at Harvard University are using the latest advances in DNA manipulation in hopes of cloning the furry giant and introducing it to the modern world.

For 12,000 years wolves roamed Scotland. However, over three centuries ago, we exterminated them. This film reveals the rise and fall of the Scottish wolf and explores the question of whether they should be re-introduced. Wolves arrived as the last ice age ended, following the herds of deer and reindeer that crossed a now-lost land bridge from Europe. For thousands of years, wolves and humans shared the landscape as apex predators, with the wolf entering human art, myth and belief. However, farming put wolves and humans on a collision course, and, after centuries of persecution, wolves became extinct in Scotland. Since then, deer numbers have exploded, and many of Scotland’s woodlands have been stripped bare. Some argue for the wolf’s return. Could we, and should we, hear the howl of the wolf once more in the Highlands?
