This episode describes the migration of most animals northwards (some from the Antarctic continent, others from the few islands surrounding it) as the continent and surrounding sea freeze over at the end of summer. It shows how young penguins often fall prey to Leopard Seals as they try to make their way across the already partially frozen water and how their stripped remains become food for isopods and meter-long nemerteans (ribbon worms). Before going to the sea, however, the adult penguins must shed their coats (molting).

The island of Barro Colorado in the Panama Canal is full of mysteries, some involving the wide diversity of wildlife, and some involving the island itself. Every year, hundreds of scientists and students come here to uncover the rainforest's secrets, but this year is very different. The island is running dry and no one knows why. Follow several research teams as they observe, experiment, and conduct research in this pristine habitat, and most pressing of all, try to find out what happened to the rain and when it will come again.

Five hundred million years ago, our previously eyeless distant ancestral creatures suddenly developed eyes, thereby marking a dramatic leap in evolution. What enabled our ancestors to suddenly evolve with eyes has been a long-unresolved great mystery in the history of our life. Now, scientists are close to cracking the mystery of the amazing story of the birth of our eyes, using cutting-edge DNA research. Travel back to a super realistic prehistoric world recreated by CGI to witness the astonishing story behind the birth of our eyes.

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.

This programme looks at the evolution of fish. They have developed a multitude of shapes, sizes and methods of propulsion and navigation. The sea squirt, the lancelet and the lamprey are given as examples of the earliest, simplest types. Then, about 400 million years ago, the first back-boned fish appeared. The Kimberley Ranges of Western Australia are, in fact, the remnants of a coral reef and the ancient seabed. There, Attenborough discovers fossils of the earliest fish to have developed jaws. These evolved into two shapes of creature with cartilaginous skeletons: wide ones (like rays and skates) and long ones (like sharks).
