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.

On the other side of the world under the crystal clear blue waters of the Pacific Ocean lies one of the most enchanting places on the planet. Over ten thousand miles away on the north eastern coast of Australia lies the Great Barrier Reef, one of the natural wonders of our world. It provides shelter to some hidden wildlife sanctuaries that contain some magical marine creatures. Iolo Williams dives deep beneath the surface of the coral sea to discover what state this natural wonder is in. He travels from the extreme swells of the northern part of the reef right down to the cooler pristine corals of the south. He discovers how healthy the Great Barrier Reef really is in some of its key locations to see and find out if there are real signs of hope the reef can survive the threat of global warming.

In this episode, Chris Packham tells the miraculous story of how plant life turned Earth from a barren rock into a vibrant green world. A four billion year saga of extraordinary highs and lows that almost wiped out all life on the planet. Four billion years ago Earth was predominantly a water world, lacking land masses, with plant life’s early ancestors trapped on the seabed. Everything changed when a giant asteroid bombardment smashed into the young planet’s crust triggering plate tectonics - Earth’s extraordinary land building force. As opportunities on land grew, plants faced an epic struggle to establish themselves in a world dominated by giant eight metre fungi, overcoming death and dehydration and eventually creating the life-giving substance that would allow them to prosper: soil. But just as they seemed set to triumph, evolving into the amazing biological machines that are trees, they became the victims of their own success. Giant swamp forests sprang up, locking up so much carbon dioxide, that global temperatures plummeted sending Earth into one of its most terrifying chapters yet.

The first episode tells how invertebrates became the first creatures of any kind to colonise dry land. Their forerunners were shelled and segmented sea creatures that existed 400 million years ago. Some of them ventured out of the water to lay their eggs in safety, and Attenborough compares those first steps with today's mass spawning of horseshoe crabs off the Atlantic coast of North America.
