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.

The next programme deals with flying insects. It begins in Central Europe, where the Körös River plays host to millions of giant mayflies as they rise from their larval skins to mate. — the climax of their lives. Mayflies and dragonflies were among the first to take to the air about 320 million years ago, and fossils reveal that some were similar in size to a seagull. Damselflies are also looked at in detail.

The final programme looks at the superorganisms formed by bees, ants and termites. Attenborough reveals that their colonies, whose individuals were once considered purely servile, are "full of conflict, power struggles and mutinies." They evolved when such creatures moved away from a solitary existence and started building nests side-by-side, which led to a collective approach to caring for their young.

Who are you going to call when beavers are behaving badly? Well, if you live in Jackson Hole, Wyoming, Drew Reed is the go-to 'beaver buster'. Drew works as a wetland conservationist, helping to keep the peace between beavers and people. These busy rodents are incredibly industrious - felling trees and building dams are two of their favourite occupations. This can be good news in the wild, helping create rich habitats for a variety of wildlife, but in back yards it can spell disaster. A beaver is more than capable of bringing down a tree large enough to damage property, and their dam building can result in flooded homes. Drew must do what he can to steer beavers away from trouble and stop their so-called bad behaviour.
From penguins whose salt-removing eye glands shield them from the harsh ocean to caterpillars whose fake facial markings are meant to mimic a snake's, animals have evolved in amazing ways to see and be seen. Meet these creatures and see how they use eyes and illusions to their advantage.
For the last decade, a team of frontline medics has been fighting to save Borneo's critically endangered orangutans. Armed with cameras, International Animal Rescue has documented their struggle: pulling apes from devastated jungle, giving emergency medical care, rehabilitating and releasing the healthiest orangutans back into the wild. This is both the story of their life-saving work and of how one of our closest wild relatives has been pushed to the brink of extinction. Combining genuine rescue footage with contributions from experts throughout, this documentary looks toward the future and asks what hope remains to save the orangutan.

To survive, animals need somewhere to live, a place that provides the necessities of life, shelter from the elements and a refuge from enemies. Good homes are rare and competition can be intense – finding a home is one thing, but defending it is quite another.
