Dr Nigel Spivey explores how art influences life by tracing the development of the image from cave paintings to our modern obsession with images. Dr. Spivey begins his investigation by travelling to the Cave of Altamira near the town of Santillana del Mar in Cantabria, Spain, where in 1879 a young girls exclamation of 'Papa, look, oxen!' to her father, local amateur archaeologist Marcelino Sanz de Sautuola, is explained to have meant that Maria had just become the first modern human to set eyes on the first gallery of prehistoric paintings ever to be discovered.

The big blue is the world's greatest wilderness, far from shore and many kilometres deep. It's a vast marine desert where there is little to eat and nowhere to hide. Yet it's home to some of the biggest and most spectacular creatures on earth. This episode reveals what it takes to survive in this savage and forbidding world. We witness feats of incredible endurance, moments of high drama and extraordinary acts of heart-wrenching self-sacrifice. Every animal in the big blue must find their own unique way to survive. Sperm whales have the largest brains in the world. They live for 80 years, and we are only now beginning to learn the extraordinary complexity of their language of clicks - thought to coordinate the whole family in everything from childcare to hunting. With special pressure-proof cameras, we witness record-breaking feats of endurance as they hunt for squid a kilometre down into the abyss. Only recently have we begun to solve the mystery of where baby turtles disappear to in their early years. They leave the crowded waters of the coast and head to the open ocean, where they use floating debris like logs as life rafts. Here they remain until adulthood, adrift on the high seas in relative safety away from coastal predators. Over half of all animals in the open ocean drift in currents. Jellyfish cross entire oceans feeding on whatever happens to tangle with their tentacles. The jelly-like Portuguese man-of-war can harness sail power to fish with its deadly tentacles. Sometimes there is a brief explosion of food in this marine desert, but ocean hunters must be fast to make the best of this bonanza. We witness super pods of up to 5,000 spinner dolphins racing to herd vast shoals of lanternfish, briefly caught at the surface where it is thought they spawn. New aerial footage reveals, for the first time, the truth to a centuries-old sailors' legend of the 'boiling seas' - the spectacular feeding frenzy of 90kg tuna and dolphins smashing through the lantern fish shoals turning the sea white with foam.

An extraordinary journey tracing the footsteps of early Homo sapiens leaving Africa, reaching the easternmost end of the Eurasian continent, and developing unique culture there. The latest palaeoanthropological findings and CGI created by top game creators will stun the viewers.

Privately, he was humble, almost shy, and fiercely patriotic, donating millions to his native Brazil and contemplating a life beyond motor-racing. Yet he is struck down in his prime on the blackest weekend in the history of the sport, watched live on television by 300 million people. Years on he is revered in Formula One as the greatest motor racing driver of all time - and in Brazil as a Saint.

As tides rise and fall twice a day, vast amounts of water swirl around the earth. This is a huge energy source that's currently largely untapped. An estimated 3000 gigawatts are available to be harvested globally, enough to power a third of the earth's homes. Yet compared to wind and solar, the technology needed to harness tidal power is still in its infancy. The power of the ocean’s tides is the last great untapped energy source on Earth. From sub-sea kites to floating platforms, teams of engineers are racing to perfect the technology to harness the vast flows of water.

This is the first of two episodes dissecting the psyche of Daniel Ricciardo. A second big money move in two years now sees the Australian set foot on the shore of the McLaren Technology Centre, only to find the territory is already occupied by Lando Norris. The Australian looks like he was really hoping to flash the car up into Q3 with his teeth, only to find it isn’t that easy.
Ricciardo is really struggling to get his head around the idiosyncratic MCL35M, but it gets worse: his boyish, funny, charismatic team-mate Norris is doing him over every week. The relations between the two drivers deteriorate also. Can Ricciardo recover his form?
The footage is interspersed with short scenes featuring Ferrari drivers Charles Leclerc and Carlos Sainz.
