Oxygen – we all need it, we can't live without it. It's integral to life on this planet. And it's probable that, as you watch this film, you will be breathing in an oxygen atom that was also breathed by Genghis Khan – or by the first ever apes to stand upright on the plains of Africa. The oxygen that we breathe is made from two oxygen atoms joined together – O2. They were first joined more than 3 billion years ago by the earliest blue-green algae to evolve. The oxygen molecule first came from bacteria and was present in the fires that destroyed the dinosaurs and the chemical reactions in all human cells, and as ozone they protect the earth from radiation. Since then, both together and apart, they've had the most extraordinary adventures. Each of the two atoms in an oxygen molecule is virtually indestructible – so they have been first-hand players in some of the most dramatic events in the whole of Earth's history. It's often said that we are breathing the same oxygen that the cavemen did. The life of a single molecule of oxygen is traced on it's astonishing journey spanning millions of years, from its creation, into photosynthesis, through the age of the dinosaurs, early man, and on into today.

Footage of animals that live in freshwater environments, from gliding treefrogs engaged in fiercely competitive mating rituals in in the Costa Rican rainforest to mugger crocodiles in Sri Lanka, that lie in wait at waterholes for chital deer. In the Okavango Delta, the arrival of the great annual flood poses a significant challenge for a pack of five African wild dogs.

One of the world’s happiest, yet most vulnerable marsupials, the Quokka thrives only on Rottnest Island. In almost plague proportions over ten thousand of the strange relic wallabies live here. How do they survive here in such inhospitable conditions and nowhere else?

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 Mediterranean. Because people have been traveling there for thousands of years, it is believed to be without secrets. And yet, far below its surface, lie vast unexplored territories, luxurious gardens worthy of the finest tropical coral reefs. These natural wonders are inaccessible to the traditional diver, in a twilight zone, between 60 and 120 m, where there’s less than 1% of sunlight. If diving at such depths is always a challenge, staying there is a fantasy, a utopia that becomes reality in Planet Mediterranean. In the tradition of Commander Cousteau and his houses under the sea, the team of diver-photographer Laurent Ballesta is undertaking a new world-record-setting mission in complete freedom and without time limit.
