Attenborough's journey continues in Canada's Rocky Mountains, where fossils document an explosion in animal diversity never seen before or since. Travelling from there to North Africa, the rainforests of Australia and the east coast of Scotland, Attenborough discovers how animals evolved to conquer not only the oceans but also the land and air. These remote and fascinating creatures are brought to life as never before with the help of cutting-edge scientific technology and photorealistic visual effects. From the first large predators to the first legs on land, these were creatures that evolved the traits and tools that allow all animals, including ourselves, to survive to this day.

Could the chemicals found in marijuana prevent and even heal several deadly cancers? Could the tumour regulating properties of cannabinoids someday replace the debilitating drugs, chemotherapy, and radiation that harms as often as it heals?

A powerful and eye-opening film about the future of cannabis and perhaps even the future of medicine.

The journey continues into Asia, the world's greatest land mass, in a quest to discover how early hunter-gatherers managed to survive in one of the most inhospitable places on earth - the Arctic region of Northern Siberia.

The Apollo equipment has sat abandoned on the lunar surface for over 40 years. Now there is a renewed excitement and drive to return to the moon. This time, not to just plant a flag, but to colonize. How would we accomplish this? And why would we do it?
The race is on to colonize the Moon, to uncover its hidden riches and discover if humanity can really survive on another world. The Moon is our gateway to our solar system, it's the stepping stone we have to become a multi-planetary species.

Dr Janina Ramirez embarks on a journey through six decades of the BBC archives to create a television history of one of the most celebrated figures in art - Leonardo Da Vinci. Ramirez shows how experts and art presenters have turned to television to bring Leonardo's artwork out of galleries and into our living rooms. Through television they have explored the origins of Leonardo's boundless curiosity, his pioneering use of light and shade, and his remarkable scientific exploration.
Along the way Dr Ramirez discovers Britain's little-known version of The Last Supper, the gruesome ways Leonardo acquired his anatomical knowledge - and even what lies beneath the Mona Lisa.

Professor Brian Cox grapples with science's darker side, asking why, when science has done so much for us, it often gets such a bad press. Starting with the original Frankenstein - the grisly 19th century tale of George Foster's hanging and subsequent 'electrocution', Brian confronts the idea that science can go 'too far'. From the nuclear bomb to genetic modification, British science has always been at the cutting edge of discovery, but are British scientists feckless meddlers, or misunderstood visionaries whose gifts to humanity are corrupted by the unscrupulous?
