In Tokyo, there are unapproachable "lost islands" with unspoiled environs and rich wildlife. Minami Iwo-to, part of the Ogasawara island chain, is about 1,300km from the Japanese capital. Normally, entry is banned to protect the environment. An exception was made in 2017 for the first comprehensive scientific survey in 10 years. The island compresses multiple climate zones into a small area, offering researchers a rare opportunity to view evolution in action. Braving an arduous climb and a swarm of seabirds, the team discovers one new species after another.

David Attenborough reviews the scientific discoveries that have transformed our view of life on earth during his lifetime. How and where did life first begin? How do continents move? How do animals communicate? And why do they behave the way they do? Sir Attenborough shares his memories of the scientists and the breakthroughs that helped shape his own career. He also recalls some of his most memorable attempts to bring new science to a television audience - by standing in the shadow of an erupting volcano as lumps of hot lava crashed around him, by being charged by a group of armed New Guinean tribesmen and the extraordinary sight of chimps hunting monkeys, captured on camera for the first time by Attenborough and his team.

The Luangwa Valley in Zambia experiences one of the toughest dry seasons imaginable. Seven months with no rain and spiralling temperatures. And with this year’s El Nino conditions the drought is threatening to be even more intense than usual.

Steve Backshall reveals the incredible influence that insects and their close relatives have on Earth's many ecosystems. In the grasslands of South America the landscape has been created almost solely by one team of insects - grass-cutter ants. Across the world's oceans one tiny creature plays such a key role that, without it, the largest animal on our planet, the blue whale, could not exist. And in East Africa the savannah would quickly be swamped in dung were it not for the activities of a certain beetle. Yet the greatest influence of all comes from a group of insects that have ultimately changed the colour and diversity of our planet.

The remarkable story of 43-year-old Sudan, the very last male northern white rhino on the planet. Aged just three, Sudan was snatched from his mother's side in Central Africa. He became a prized exhibit in a zoo behind the Iron Curtain, while the rest of his kind was poached to extinction in the wild. Today, Sudan has become an unwitting celebrity and the focus of a desperate eleventh hour battle to save his sub-species. This astonishing modern-day fable is told through the international cast of characters who have been involved in Sudan's life, for better and for worse.
