Can Science Explain the Origin of Life?

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.

What is DNA and How Does it Work?

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?

What is Evolution?

Evolution is often considered a complex and controversial topic but it's actually a very simple concept to understand. Watch this short animation to see how evolution works.

What is Natural Selection?

Natural Selection is one of the main concepts found within the theory of evolution. It was discovered by Charles Darwin and Alfred Russel Wallace though Darwin championed the idea in his book "On the Origin of Species".

Does the Theory of Evolution Really Matter?

The discovery of biological evolution is among the most significant scientific findings of the last 200 years. It has lead us to thousands of new discoveries and is greatly expanding our understanding of the natural world.

What is the Evidence for Evolution?

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.

What Was The Miller-Urey Experiment?

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.

Congo

David Attenborough takes a breathtaking journey through the vast and diverse continent of Africa as it has never been seen before. (Part 3: Congo) The very heart of Africa is covered in dense tropical rainforest. The animals that live here find the most ingenious ways to carve out their space in a claustrophobic landscape. Danger lurks in every shadow, but some animals thrive here, from honey-stealing chimps to birds with a lineage as old as the dinosaurs, thundering elephants and kick-boxing frogs. Here in the Congo, no matter how tough the competition, you must stand up and fight for yourself and your patch.

Man's Best Friend

A look at how dogs have become part of human life and the closest of companions. An example of this special relationship is the amazing story of a cliff-diving Jack Russell.

Plants

Plants' solutions to life's challenges are as ingenious and manipulative as any animal's. Innovative time-lapse photography opens up a parallel world where plants act like fly-paper, or spring-loaded traps, to catch insects. Vines develop suckers and claws to haul themselves into the rainforest canopy. Every peculiar shape proves to have a clever purpose. The dragon's blood tree is like an upturned umbrella to capture mist and shade its roots. The seed of a Bornean tree has wings so aerodynamic they inspired the design of early gliders. The barrel-shaped desert rose is full of water. The heliconia plant even enslaves a humming bird and turns it into an addict for its nectar.

After Life: The Strange Science of Decay

If you have ever wondered what would happen in your own home if you were taken away and everything inside was left to rot, the answer is revealed in this programme which explores the strange and surprising science of decay. For two months, a glass box containing a typical kitchen and garden was left to rot in full public view within Edinburgh Zoo. In this resulting documentary, Dr George McGavin and his team use time-lapse cameras and specialist photography to capture the extraordinary way in which moulds, microbes and insects are able to break down our everyday things and allow new life to emerge from old. Decay is something that many of us are repulsed by, but as the programme shows, it's a process that's vital in nature. And seen in close up, it has an unexpected and sometimes mesmerising beauty.

Tasmania: Weird and Wonderful

David Attenborough reveals that the animal inhabitants of this vast wilderness are every bit as extraordinary as they are bizarre. Unearthly calls of the notorious Tasmanian devil echo through the land, but following them over the course of a year reveals a surprisingly gentle side. In the dry east, rare white wallabies graze on the plains and jack jumper ants build huge nests – these venomous ants are amongst the most dangerous on earth. In the west, where it can rain nearly every day of the year, caves light up with the magical spectacle of thousands of glow-worms, and the trees are 100-metre towering monsters. Rivers are home to the peculiar platypus, and world’s largest freshwater invertebrate, the Tasmanian giant lobster. Miniature penguins come ashore to breed, and as winter approaches, the southern lights dance in the sky. Tasmania’s isolation and unique climate has created a world that is as weird as it is wonderful.
