Toumai: The Oldest Human Ancestor

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. The discovery opens a highly focused window on the vanished world of the Ice Age in North America.

Many geneticists and archaeologists have long surmised that human life began in Africa. Dr. Spencer Wells, one of a group of scientists studying the origin of human life, offers evidence and theories to support such a thesis in this PBS special. He claims that Africa was populated by only a few thousand people that some deserted their homeland in a conquest that has resulted in global domination.

Sixty-six million years ago, an asteroid wiped out the dinosaurs in a fiery global catastrophe. But we know little about how their successors, the mammals, recovered and took over the world. Now, hidden inside ordinary-looking rocks, an astonishing trove of fossils reveals a dramatic new picture of how rat-sized creatures ballooned in size and began to evolve into the vast array of species—from cheetahs to bats to whales to humans—that rule our planet today.

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.

In May 2002 a group of people went looking for dinosaur and here is what they found!

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.

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.

David Attenborough searches for the identities of preserved creatures inside a piece of Baltic amber that was given to him by his adoptive sister when he was twelve years old.

Fossils reveal how birds survived the killer asteroid and became today's only living dinosaurs.

A mining operation in Cerrejon, Northern Colombia revealed a treasure trove of fossils from animals that lived ten million years after the KT extinction that killed the dinosaurs. Surprisingly, enormous reptiles were dominate. Scientists investigate who was the apex predator of the era - Titanoboa, a quarter ton giant snake five times bigger than the largest anaconda, or a similarly giant crocodilian with an incredibly deadly bite force. —David Foss
