Moving on to Ethiopia 3.2 million years ago, we witness the beginnings of mankind via a group of australopithecus - a type of ape which, like us, walks upright on two legs. But unlike us, these early members of the human family weren't predators, they were prey. Things get worse for the group as they are hunted by a sabre-tooth cat called dinofelis and fall victim to other dangers such as malaria, rival australopithecus and a rampaging 14-tonne deinotherium.

Presenter Michael Wood seeks out the achievements of the country’s golden age, discovering how India discovered zero, calculated the circumference of the Earth and wrote the world’s first sex guide, the Kama Sutra. In the south, he visits the giant temple of Tanjore and sees traditional bronze casters, working as their ancestors did 1,000 years ago.

On Oct. 1, 2013, the elusive British street artist known as Banksy launched a self-proclaimed month-long residency in New York City, posting one unique exhibit a day in an unannounced location, sparking a 31-day scavenger hunt both online and on the streets for Banksy’s work. Capturing this month of madness, this featured film incorporates user-generated content, from YouTube videos to Instagram photos, from New Yorkers and Banksy hunters alike, whose responses became part of the work itself, for an exhilarating, detailed account of the uproar created by the mysterious artist.
With installations spanning all five boroughs of New York City, and including a mix of stencil graffiti, sculpture, video and performance art, Banksy touched on such wide-ranging subjects as fast-food wages, animal cruelty in the meat industry, civilian casualties in Iraq and the hypocrisy of the modern art world.

Located beneath Russia's Ural Mountains, Orda Cave is legendary among divers for its unique beauty. The cave's waters are clearest in winter, when the land above lies frozen. With temperatures approaching minus 40 degrees, NHK attempts to film the cave for the first time ever using 4K cameras. Scientists give them insight into the cave's origins, enabling the crew to uncover the miraculous story of how the cave was naturally formed 300 million years ago by climate change and a shifting landscape.

Warren Buffett is truly a one-of-a-kind billionaire. The legendary investor still lives in his modest home in Omaha. At 90 years old, he drives to the office every morning to manage Berkshire Hathaway, the fifth largest public company in the world. But more surprising than his humble lifestyle is his moral core. The same principles of decency and integrity that helped him pile up a fortune led him to give it all away in the largest philanthropic donation in history.
'Becoming Warren Buffett' chronicles the evolution of an ambitious, numbers-obsessed boy from Nebraska who became one of the most richest and respected men in the world, and the heroes who helped guide him along the way. By allowing access to his life and never-before-released home videos, Buffett offers a glimpse into his unique mind to help us understand what is truly important when money no longer has meaning.

The deep is perhaps the most hostile environment on earth, at least to us - a world of crushing pressure, brutal cold and utter darkness. We have barely begun to explore it, and yet it is the largest living space on the planet. Scientists already think that there is more life in the deep than anywhere else on earth. This episode takes us on an epic journey into the unknown, a realm that feels almost like science fiction. We discover alien worlds, bizarre creatures and extraordinary new behaviours never seen before. We encounter savage hordes of Humboldt squid hunting lanternfish in the depths and coral gardens flourishing in absolute darkness, with more species of coral to be found in the deep than on shallow tropical reefs. Narrated by David Attenborough.
