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.

For many animals, from lemurs to hummingbirds, the maternal bond is one of the strongest forces in nature. Not only do mothers carry their young everywhere, feed them, and help teach them essential life skills, they're also their primary source of comfort and security.
The third episode looks at the last generation of killer dinosaurs - carnivores that took killing to a new level. By the end of the cretaceous period - 75 millions years ago - these gigantic and specialised hunter-killers had spread throughout the globe. In the southern continents it was the powerful and muscular abelisaurids that reigned supreme but it was the famous tyrannosaurids (or tyrant dinosaurs) that dominated in the north. Whilst the northern daspletosaurus hunted in gangs, using its highly developed smell and hearing to take down opponents like the horned rhino-sized beast, chasmosaurus, in the Southern hemisphere the small-skulled majungasaurus reigned. And though the sharp toothed majungasaurus was an efficient killer of the much smaller feathered rahonavis that did not stop it from occasionally turning cannibal and hunting its own.
A fascinating look at the secret, underground world of the ant colony in a way that has never been seen before. At its heart is a massive, full-scale ant nest, specially-designed and built to allow cameras to see its inner workings. The nest is a new home for a million-strong colony of leafcutter ants from Trinidad. For a month, entomologist Dr George McGavin and leafcutter expert Professor Adam Hart capture every aspect of the life of the colony, using time-lapse cameras, microscopes, microphones and radio tracking technology. The ants instantly begin to forage, farm, mine and build. Within weeks, the colony has established everything from nurseries to gardens to graveyards. The programme explores how these tiny insects can achieve such spectacular feats of collective organisation. This unique project reveals the workings of one of the most complex and mysterious societies in the natural world and shows the surprising ways in which ants are helping us solve global problems.

Part one of two. Thirty years ago explorer Benedict Allen lived in Papua New Guinea with the Niowra, a remote people. Broadcast journalist Frank Gardner has always wished to see wild birds of paradise, so Benedict resolves to take him along. The duo set out through some of the most inhospitable terrain on the planet, negotiating swamps, mountains and crocodile-infested waters, heading into the cloud forest. Despite Frank requiring the use of a wheelchair following a shooting incident in 2004, Benedict determines to get him to their destination.
The volcanic Kamchatka peninsula is located on the far east of Russia. Because of the frequent volcanic eruptions and landslides, the terrain is constantly changing. But, despite the fact that the remote Kamchatka region is considered dangerous, it is unusually rich and fertile. Exploring the riches of this magical land, our film does not miss anything. In the frame - the golden eagles soaring in the sky, the wolverine, scavenge, the whole family of red foxes, and even the owners of these places - brown bears, happy to take baths in natural hot springs.
