The next programme deals with flying insects. It begins in Central Europe, where the Körös River plays host to millions of giant mayflies as they rise from their larval skins to mate. — the climax of their lives. Mayflies and dragonflies were among the first to take to the air about 320 million years ago, and fossils reveal that some were similar in size to a seagull. Damselflies are also looked at in detail.
The theory of evolution explains how the enormous variety of life could come into existence. How it is possible for primitive life forms to spawn the millions of different creatures, that exist today. Unfortunately, evolution is often misunderstood, because it's mechanisms seem counter intuitive. By using visualizations, infographics and appealing characters, the viewer is more likely to understand it the complex information.
Part two of two. Explorer Benedict Allen is determined to get disabled journalist Frank Gardner into the wilds of Papua New Guinea, despite having to grapple with Frank's wheelchair. As the terrain gets even tougher to negotiate, the pair know they must make an epic journey into the highlands, crossing through two tribal territories to achieve their objective. However, as Frank gets close to realising his dream of seeing wild birds of paradise up-close, his old injuries return to haunt him and the expedition hangs on a knife edge.
From the shelter of our homes, snow looks magical, but it's a harsh reality to many animals. Snow means freezing temperatures, which these animals must endure for many months. Wildlife cameraman Gordon Buchanan meets some of the world's most iconic snow animals across the globe, from the penguins of Antarctica to the bison of Yellowstone and the Arctic fox. Beyond the Arctic Circle in northern Norway, he encounters wolves, lynx, reindeer, polar bears, muskox, and even a woolly bear - the most miraculous, coolest Arctic caterpillar! Buchanan reveals the incredible adaptations and extraordinary strategies these animals use to survive.

Sir David Attenborough tells the stories of the world's best animal architects. There are house-proud bower birds, who only find a mate if they decorate their homes perfectly. There are hornets, who build electric central heating systems, and the star-nosed mole, whose house is designed so well that worms, his favourite meal, literally drop in for dinner. From larders to nurseries and from high-rises to subway systems, Attenborough shows that the animal architects have designed it long before humans.
