Charles Darwin and the Tree of Life

Darwin's great insight – that life has evolved over millions of years by natural selection – has been the cornerstone of all David Attenborough’s natural history series. In this documentary, he takes us on a deeply personal journey which reflects his own life and the way he came to understand Darwin’s theory.

Dinosaur Extinction: Behind the Asteroid Impact Theory

The discovery of a giant crater in the floor of the Gulf of Mexico is a step closer to solving the question if an asteroid ended the age of dinosaurs.

Blue Gold: World Water Wars

Wars of the future will be fought over water as they are over oil today, as the source of human survival enters the global marketplace and political arena. Corporate giants, private investors, and corrupt governments vie for control of our dwindling supply, prompting protests, lawsuits, and revolutions from citizens fighting for the right to survive.

Vanishing: The extinction crisis is worse than you think

We're entering the Earth's sixth era of extinction -- and it's the first time humans are to blame. CNN introduces you to the key species and people who are trying to prevent them from vanishing.

How to Build a Dinosaur

Dinosaurs died out 65 million years ago and we have hardly ever found a complete skeleton. So how do we turn a pile of broken bones into a dinosaur exhibit? Dr Alice Roberts finds out how the experts put skeletons back together, with muscles, accurate postures, and even - in some cases - the correct skin color. Here's a conundrum. Most dinosaur skeletons are incomplete, so how do you create museum exhibits that are realistic? As Dr Alice Roberts discovers, it's a practical question for those putting together an exhibition at LA County's Natural History Museum, who have to design dynamic, punter-pleasing displays that also reflect the latest thinking in paleontology circles.

After Man

A stop-motion adaptation of the 1981 novel by geologist Dougal Dixon of the same name, which explores the speculative paths of evolution of modern animals into the far future.

Attenborough and the Sea Dragon

Sir David Attenborough investigates the discovery of a 200 million year old Ichthyosaur on the Jurassic Coast in southern England. Using state of the art technology and CGI David brings the story of the fossilised ichthyosaur out of the rock and shows us what this creature was really like as it lived during the Jurassic time period.

How To Clone A Woolly Mammoth

The Siberian discovery of the best-preserved woolly mammoth on record has teams of experts working around the globe, and around the clock, on some of the most ambitious projects in science. In Russia, paleontologists are conducting a historic autopsy on the 40,000-year-old beast to find out how it lived, and how it died. Meanwhile labs in South Korea and at Harvard University are using the latest advances in DNA manipulation in hopes of cloning the furry giant and introducing it to the modern world.

Whatever Happened to the Dinosaurs?

Canicule 2003 : Paris dans la fournaise

The heatwave of 2003 remains etched in our memories. We remember an angry emergency doctor, crowded hospital corridors, and a health minister in a polo shirt who seemed completely out of touch with reality. Between August 1 and 20, 2003, the heatwave claimed 15,000 lives. One in three victims lived in the Ile-de-France region, which was hardest hit by this deadly heatwave. This tragedy revealed many shortcomings. First, the lack of preparedness of the public authorities to deal with such a health crisis. Second, the way in which the elderly are treated. Climatologists estimate that from 2050 onwards, the summer of 2003 will be the norm. Hyper-urbanization, poor insulation in homes, and a lack of green spaces are all factors that exacerbate the effects of high temperatures.

Dinosaurs on Ice

Deep inside the arctic, scientists are experimenting with extreme palaeontology methods to unlock the secrets of polar dinosaurs, and perhaps the key to our own survival on Earth. On Alaska's north slope there are dinosaur bones, lots of them. But they're trapped in an icy tomb - an impenetrable wall of permafrost. Dinosaurs on Ice follows the journey of two scientists, Dr Tom Rich and Dr Tony Fiorillo, who undertake separate expeditions to the Colville River in Alaska's far north to uncover the dinosaurs' bones and break the ice on a prehistoric world that until now has been unreachable. But the task is not easy. The weather is extreme, the location remote.

Desert PHOSfate

DESERT PHOSfate is an artist film that tells about the impact of phosphate on the Sahrawi community and its fate, including the surprising emergence of family gardens and their knowledge of how to farm in the desert without the processed phosphorus that had caused the dislocation of the Sahrawi nomads from their homeland of Western Sahara.

Ice Age Death Trap

In a race against developers in the Rocky Mountains, paleontologists uncover a unique fossil site packed with astonishingly well-preserved bones of mammoths, mastodons, and other giant extinct beasts.
