The first part explores how centuries of scientific and religious dogma were overturned by the earliest discoveries of the existence of cells, and how scientists came to realize that there was, literally, more to life than meets the eye.
The second episode of this unique scientific study reveals the wild side of pet cats. Using GPS trackers and cat cameras, they show how these felines transform from pampered pet to purring predator as soon as they leave the cat flap. Liz Bonnin and some of the world's top cat experts put Ozzy and Smudge under surveillance to find out who is king of the street and reveal why, no matter how hard we try, we can't keep our cats' hunting instincts under control.
Across our planet, there are a handful of places that truly astonish, like Mount Everest, the Grand Canyon and Victoria Falls. These wonders seem to have little in common other than - literally - taking your breath away. But they share one other thing: they pose extraordinary challenges for their inhabitants. The second of two documentaries profiling some of the world's most expansive - and inhospitable - landscapes, and the people who live there. A fisherman in Zambia faces off against crocodiles and risks being swept to his death as he tries to make a living above the imposing Victoria Falls, and in the Amazon, a giant fish offers salvation to a hungry family that calls the river home. A boy's future hangs on the outcome of a single horse race in the vast grasslands of the Steppe, and in a European salt marsh, a young man duels with a savage bull in a centuries-old battle of wills.
Despite the scorching heat, a cold upwelling of nutrients in the Gulf of Oman creates favorable conditions for a host of marine migrants. The behemoth whale shark, hawksbill turtle, and millions of tiny, exotic fish settle in to feast. Take a plunge into the algae-cloaked coral reefs of this underwater tapestry.
The episode begins in the South American rainforest whose rich variety of life forms is used to illustrate the sheer number of different species. Since many are dependent on others for food or means of reproduction, David Attenborough argues that they couldn't all have appeared at once. He sets out to discover which came first, and the reasons for such diversity. He starts by explaining the theories of Charles Darwin and the process of natural selection, using the giant tortoises of the Galapagos Islands (where Darwin voyaged on HMS Beagle) as an example. Fossils provide evidence of the earliest life, and Attenborough travels a vertical mile into the Grand Canyon in search of them.
Blue Whisper immerges into the ocean's fascinating underwater world and gets to the bottom of a widely unexplored field of underwater science: the communication among fish. The documentary accompanies a team of specialists to overwhelmingly beautiful coral reefs, ancient shipwrecks in the Mediterranean Sea and sunken submarines that are clouded in secrecy, to explore the versatile forms of underwater communication. What language do fish use? Do they make sounds? Do they have a body language? And what role do colours play? With the aid of complex underwater video and audio equipment those and further questions are answered during a suspenseful journey around the world.
