The penultimate episode focuses on the relationships between invertebrates and plants or other animals. It begins with ants and aphids: the former 'herd' the latter and protect them in return for secreted honeydew.
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.

In the heart of Brazil lie the immense wetlands of the Pantanal--an area 10 times the size of the Florida Everglades. In the dry season, over 650 species of birds descend onto the shallow marshes to feast, breed, and raise their young, including the the regal jabiru, the colorful hyacinth macaw, and the noisy chacalaca.
High above the skies of Israel, an avian migration of staggering proportions attracts birdwatchers from all over the world. From gliding birds like the short-toed eagle to waders like red-necked phalaropes, here's your chance to track one of the most important stops on the bird migration route--no binoculars needed.
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 first of two programmes in which cameras explore some of the most inhospitable places on the planet and the people who live there, including a team of Sherpa roping a route on Mount Everest's notorious Khumbu Icefall and, on the slopes of Mount Kilimanjaro, farmers fight pitched battles to save their crops from marauding elephants. In the Amazon rainforest, two boys undergo a rite of passage involving hundreds of ants with the most painful stings on Earth, and conservationists in the Grand Canyon try to ensure the survival of one of America's few surviving condor chicks.
A young jaguar embarks on the first solitary hunt of his adult life, deep in the Pantanal, a vast wetland 10 times larger than the Everglades. His target is a savage caiman, a relative of the crocodile, who will fight back for any opportunity to turn the tables on his inexperienced predator.
Located on the Malilangwe Game Reserve in southern Zimbabwe, this 800-year-old baobab is a remarkable tree containing its own ecosystem. Capable of withstanding extreme drought by storing water in its hollow trunk, it draws a multitude of wildlife, from elephants who strip its bark in search of food, to vultures that nest on its branches. Remarkably, it also has another gift: a velvety fruit packed with an astonishing cocktail of nutrients. To witness the baobab is to be awed by the natural forces that produced it.
