Darwin's theory of biological evolution helps us understand how simple life forms can give rise to complex lifeforms, but how did the first reproducing creatures come about? The origin of life needs its own explanation.
Issues of genetics and DNA are constantly cropping up in the news from food production and health, to legal cases and ethics. We hear about DNA in movies like Jurassic Park and X-men, we learn bits and pieces about it from TV shows like Dexter and and CSI, but what exactly is DNA, and how does it work?
Biologists teach that all living things on Earth are related. Is there any solid evidence to back this claim? Join us as we explore the facts! We start with a close look at the origin of whales from land mammals, and then touch on the origins of several other critters, including our own species.
The Miller-Urey experiment was the first attempt to scientifically explore ideas about the origin of life. Stanley Miller simulated conditions thought be common on the ancient Earth. The purpose was to test the idea that the complex molecules of life (in this case, amino acids) could have arisen on our young planet through simple, natural chemical reactions.

It’s sexy time with the arthropods! This week David Attenborough takes a look at the courtship rituals of the creatures beneath our feet. But lovebugs won’t want to take tips from these bugs. The male Chilean rose tarantula, for instance, weaves a silk mat; deposits sperm on it, then sucks that sperm into a finger-like appendage near his mouth before he looks for a mate. Then there’s the gruesome, but surprisingly effective, coupling of praying mantis. The cinematography is as amazing as ever, catching the mating battles of tramp ants and providing luminescent footage of the courtship dance of Tanzanian red claw scorpions.
From penguins whose salt-removing eye glands shield them from the harsh ocean to caterpillars whose fake facial markings are meant to mimic a snake's, animals have evolved in amazing ways to see and be seen. Meet these creatures and see how they use eyes and illusions to their advantage.
They are among the most hated and feared animals on the planet - only few people recognize their beauty. This documentary features some of Europe's most stunning species, like the European adder, the nose-horned viper, the dice snake, the ringed snake and the Aesculapian snake. So watch out next time you're walking in the park. After a winter safe in burrows, sometimes in bundles of hundreds, the spring's warmth brings them back to life.

This is the story of two tiny animals coming of age. In the wild woods of North America, a young chipmunk is gathering a vital store of nuts ahead of his first winter - in his way are ruthless rivals and giant predators. In the steaming rainforest, a young tree-shrew is forced deep into the jungle to find food. She must draw on all her intelligence and agility if she is to escape the ultimate jungle predator - a reticulated python!
