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?

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 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.

Urals - Primordial Valley

Take a journey through majestic primeval forests of the Urals. These protected sites are known for their extremes, where the fine side by side, and giant deer, and giant leviathan, weighing half a ton, and tiny animals. This also, in search of food, make their seasonal raiding Eurasian elk. Unlike other types of elk Eurasian elk live alone, so for the pregnant female elk stress of meeting with other animals usually leads to a fight. As soon as the snow begins to melt in the woods, baring the ground, a lone wolf set out in search of food, not disdaining the frozen remains of animals

The British Garden: Life and Death on Your Lawn

The British back garden is a familiar setting, but underneath the peonies and petunias is a much wilder hidden world, a miniature Serengeti, with beauty and brutality in equal measure. Chris Packham and a team of wildlife experts spend an entire year exploring every inch of a series of interlinked back gardens in Welwyn Garden City. They want to answer a fundamental question: how much wildlife lives beyond our back doors? How good for wildlife is the great British garden? Through all four seasons, Chris reveals a stranger side to some of our more familiar garden residents. In summer he meets a very modern family of foxes - with a single dad in charge - and finds that a single fox litter can have up to five different fathers. In winter he shows that a robin's red breast is actually war paint. And finally, in spring he finds a boiling ball of frisky frogs in a once-in-a-year mating frenzy. The secret lives of the gardens' smallest residents are even weirder. The team finds male crickets that bribe females with food during sex, spiders that change colour to help catch prey, and life-and-death battles going on under our noses in the compost heap. So how many different species call our gardens home? How well do our gardens support wildlife? By the end of the year, with the help of a crack team from London's Natural History Museum and some of the country's top naturalists, Chris will find out. He'll also discover which type of garden attracts the most wildlife. The results are not what you might expect... You'll never look at your garden in quite the same way again.
