All habitats present challenges to life, but few more so than the desert, but still, even here, life abounds, from little foxes to speed lizards and light-footed gazelles to huge camels. Each one finds its own ways to exploit and conserve food and water, creating new dramas every day.

Reptiles and amphibians look like hang-overs from the past. But they overcome their shortcomings through amazing innovation. The pebble toad turns into a rubber ball to roll and bounce from its enemies. Extreme slow-motion shows how a Jesus Christ lizard runs on water, and how a chameleon fires an extendible tongue at its prey with unfailing accuracy. The camera dives with a Niuean sea snake, which must breed on land but avoids predators by swimming to an air bubble at the end of an underwater tunnel. In a TV first, Komodo dragons hunt a huge water-buffalo, biting it to inject venom, then waiting for weeks until it dies. Ten dragons strip the carcass to the bone in four hours.
Rodents like rats, mice and squirrels are the most numerous mammals on the planet. This programme reveals how, with their constantly growing, chisel-sharp front teeth, they are specialists in breaking into seeds. It also shows how they have adapted this talent to help them make their homes and even live underground, as well as revealing their ability to store food - and their ability to breed prolifically.
A look across Hawaii's varied islands, discovering how they were made, and how its wildlife thrives. The most remote island chain on Earth, its tropical shores are hard to reach. However, for the hardy creatures that have made it there, such as the waterfall-climbing fish, carnivorous caterpillar and Laysan albatross, a land of opportunity awaits. From newly formed lava fields, to lush jungles, and vibrant coral reefs, these diverse and beautiful islands have it all. As this documentary reveals, its people are looking to the future and attempting to protect and foster its flora and fauna.
The final episode deals with the evolution of the most widespread and dominant species on Earth: humans. The story begins in Africa, where, some 10 million years ago, apes descended from the trees and ventured out into the open grasslands in search of food. They slowly adapted to the habitat and grew in size. Their acute sense of vision led to them standing erect to spot predators, leaving their hands free to bear weapons. In addition, the primitive apemen also had stones that were chipped into cutting tools. Slowly, they grew taller and more upright, and their stone implements became ever more elaborate.
