No continent experiences seasonal change as extreme as North America. From tornados that roar across the prairies, to Arctic air sweeping through the humid, southern swamps - this is a land where pioneering animals thrive. In winter, lynx prowl the snowy Yukon for snowshoe hares, whilst Florida manatees seek hot springs to escape the freeze. In the creeks of Tennessee, fish build spectacular underwater pyramids to find a mate. Fireflies light up the forests during summer nights, roadrunners cruise the spectacular deserts of Arizona and polar bears leap from rocks to hunt beluga whales.

This crowded continent hides the most surprising animals in pockets of wilderness. Above Gibraltar, Europe’s only primate lives a life of kidnapping and high drama, whilst in the cemeteries of Vienna grave robbing European hamsters do battle with each other. Come nightfall, the Italian mountain villages are the hunting grounds for rarely seen wolves, whilst lynx lurk in the forests of Spain. Deep underground in Slovenia’s caves, baby dragons live for up to a hundred years. Meanwhile, on the surface the continent has been developed beyond recognition.

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.
Over 62 per cent of adults in the UK are currently overweight or obese and this figure is set to rise. A common attitude is that obese people should be ashamed - it is their fault, they have no will power and if they could just 'eat less and exercise more', the problem would soon be solved. Yet, despite millions of pounds being spent on this simple message, the UK is getting fatter every year. Cambridge geneticist Dr Giles Yeo believes that for many obese people, simply eating less is a lot harder than you might think - and he is taking a road trip around the UK and America to uncover why. He meets the real people behind some of the more shocking newspaper headlines and, through their stories, reveals surprising truths which dispel commonly held myths about obesity. He gains access to scientists and doctors trialling cutting-edge techniques to tackle the crisis - from a 'miracle' hormone injection to a transfusion of faecal matter, and even learns a thing or two about his own size and relationship with food.
More than a billion people around the world commute into cities each day, and they are not alone. The world's wildlife is commuting too. A steady flow of animals journey in and out of cities to find food and shelter or to start a family. Leaving the wilderness they must overcome the unique challenges that the urban world throws at them to benefit from the opportunities on offer. This episode explores whether the secret to an animal's success in this fast-changing world is to keep one foot in the wild and one in the city, becoming a wild commuter. It seems that all over the world animals are finding that the city can offer opportunities that are harder to come by in the natural world. Some, like African penguins, whose population has plummeted by 80 per cent in the last 50 years, find shelter in the city. By nesting in Cape Town they are safer from predators, and with relatively easy access to their fishing grounds they have the best of both worlds. Many other animals commute into cities because they are filled with food. In St Lucia, South Africa, that includes hippos. Able to eat up to fifty kilograms of grass in a single sitting, they have developed a taste for the short, manicured lawns and come to town every night to dine out. St Lucia's human residents have learnt to give the hippos the space they need during their night-time raids. Black bears need to eat more than 20,000 calories a day to survive their six-month hibernation through winter, and using their acute sense of smell they can easily track down leftovers. In North America they come into towns and cities in search of food. Many animals displaced from their natural habitat are now using their wild skill set in the city to help fulfill their needs. Could this be the beginning of a new and very modern migration?

In the first of a two-part series, Dr Jago Cooper reassesses the achievements of the Inca Empire. He begins in Peru, where evidence is still being uncovered that challenges preconceptions about its origins and significance. Venturing from the coast to the clouds, he reveals how the Inca transformed one of the most challenging landscapes in the world to ward off the worst effects of the climate, and created sophisticated systems of communication. He shows how one of many independent societies became a commanding empire - not through force, but by using subtle methods of persuasion.

Hitler personally arranges for a euthanasia program, underestimating the resistance of the Church. The killing of the mentally ill has to be slowed down, but the extinction of Jews is expanded to an industrial scale. Russian prisoners of war are murdered directly, abused, or left to starve. Most Germans know of these crimes even if they refuse to acknowledge them.
When Hitler expounded his intention to invade Russia his generals looked at him in horrified silence. The Soviet Union was vast and had matchless resources. Hitler's whole plan depended upon striking a swift and decisive knock-out blow. Get sucked into a long, drawn-out war and Germany would surely lose. Hitler was certain his forces could do it. No one had so far defeated them. But there had never been a military gamble like it... This film takes in Stalingrad and the battle of Kursk, the biggest tank battle in all history.

Our lifespan is increasing by 2.5 years every decade - and a third of all babies born today can expect to live to 100. But living longer can come at a cost. Old age itself brings with it a range of debilitating illnesses, many of which are the result of accumulating damage during our lifetime. Three diseases in particular have become the main killers in the developed world - cancer, heart disease and dementia. But a revolution in bio-medicine is now offering new hope for the treatment of these ailments, and the potential to extend our lives still further. Methods such as gene editing and stem cell therapies are transforming the way medicine can conquer disease today. These extreme frontiers of medicine do, however, also come with a range of ethical dilemmas - when is the right time to try out an experimental technique on a patient? Should we gene edit human embryos? And is it right to use cells from aborted foetuses for medical treatments?
