Attenborough visits several museums of natural history. With the aid of dinosaur skeletons, he demonstrates how they existed in real life, and speculates about the reasons for their sudden demise.
In this final installment to the series, David Attenborough travels to four unique locations about the globe where an abundance of fossilized plant and animal remains have given us a detailed picture of what life could have been like in prehistoric times. Each of the sites experienced its own set of circumstances which enabled it to preserve many perfect specimens for extraction and analysis. Piecing together the collected evidence, paleontologists have been able to determine early animal hierarchies, their diets and their evolutionary paths.

The big blue is the world's greatest wilderness, far from shore and many kilometres deep. It's a vast marine desert where there is little to eat and nowhere to hide. Yet it's home to some of the biggest and most spectacular creatures on earth. This episode reveals what it takes to survive in this savage and forbidding world. We witness feats of incredible endurance, moments of high drama and extraordinary acts of heart-wrenching self-sacrifice. Every animal in the big blue must find their own unique way to survive.
A look at wildlife in hostile environments, including glow-worms, condors, thorny devils, emperor penguins and polar bears. High in the mountains, deep underground, out in the deserts and at each of our vast frozen poles, animals have had to develop extraordinary resilience to survive. There are many challenges faced by animals living in extreme environments. Superbly adapted to these inhospitable habitats, their fortitude and resilience.
In nature, living long enough to breed is a monumental struggle. Many animals and plants go to extremes to give themselves a chance. Uniquely, three brother cheetahs band together to bring down a huge ostrich. Aerial photography reveals how bottle-nosed dolphins trap fish in a ring of mud, and time-lapse cameras show how the Venus flytrap ensnares insect victims. The strawberry frog carries a tadpole high into a tree and drops it in a water-filled bromeliad. The frog must climb back from the ground every day to feed it. Fledgling chinstrap penguins undertake a heroic and tragic journey through the broken ice to get out to sea. Many can barely swim and the formidable leopard seal lies in wait.
This story takes place in the vast northern land near the coast of the Sea of Okhotsk in eastern Hokkaido. Taking center stage are two mother Hokkaido red foxes caring for 10 pups. The mothers, who are in fact mother and daughter, each use their strengths and display amazing parental teamwork.
