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.

The Namib Desert is one of the oldest of all. It’s also one of the most diverse. With 50-degree temperatures and half a millimetre of rainfall annually, how is this possible?

Spring arrives in the polar regions, and the sun appears after an absence of five months; warmth and life return to these magical ice worlds - the greatest seasonal transformation on our planet is underway. Male Adelie penguins arrive in Antarctica to build their nests - it takes a good property to attract the best mates and the males will stop at nothing to better their rivals! But these early birds face the fiercest storms on the planet. In the Arctic, a polar bear mother is hunting with her cubs. Inland, the frozen rivers start to break up and billions of tons of ice are swept downstream in the greatest of polar spectacles. This melt-water fertilizes the Arctic Ocean, feeding vast shoals of Arctic cod and narwhal. The influx of freshwater accelerates the breakup of the sea-ice - an area of ice the size of Australia will soon vanish from the Arctic. On land, a woolly bear caterpillar emerges from the snow having spent the winter frozen solid. Caterpillars normally become moths within months of hatching, but life is so harsh here that the woolly bear takes 14 years to reach adulthood. Once mature it has only days to find a mate before it dies! Alongside the caterpillars white Arctic wolves race to raise their adorable cubs before the cold returns.

On a high ridge in Newfoundland, Canada, nestled between the Atlantic Ocean and the borders of an old grove forest, a Red fox, the matron of her family group, gives birth yet again. Follow the pups as they grow and learn to hunt, adapt, and survive. Explore the family dynamic of these clever creatures as bonds are formed. But the vixen knows that not all her cubs will inherit these tall trees, crystal lakes, and the ocean spray. Before the snows come again, she will have to banish some of her offspring for the good of the family. We also hear from scientists in Madison, Wisconsin and Bristol, England, about their studies on urban Red foxes who are facing a much different challenge than their Canadian counterparts. And another scientist tracks how Red foxes are moving out to the Arctic tundra and surviving in one of the harshest landscapes.

Dr Helen Czerski looks at the anatomy of an avalanche. From shocking eyewitness footage from within an avalanche, to detailed CT scans showing the microscopic changes that cause them, we can now capture exactly what happens as snow transforms into a deadly and unpredictable danger.

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".
