Looking at whether the history of early human evolution should be rewritten. For decades, most experts have been convinced that Africa is the cradle of mankind and many fossil finds from Kenya, Ethiopia, South Africa and Chad seemed to prove it.
Become a paleontologist and piece together the facts behind these real-life monsters. Experience the process of discovery from start to finish - the excitement of digging, reconstruction, and the realization of what dinosaurs might actually have looked like.
David Attenborough tells the story of the discovery and reconstruction in Argentina of the world's largest-known dinosaur, a brand new species of titanosaur.
Commentator-comic Bill Maher plays devil's advocate with religion as he talks to believers about their faith.

Dinosaur Revolution is a four-part nature documentary miniseries that utilizes computer-generated imagery to portray dinosaurs and other animals from the Mesozoic era. It was praised for its educational content and general energy. Used and unused footage was later made into a feature film titled Dinotasia.
Pro-intelligent design scholars and scientists are often chastised, fired or denied tenured positions by those who believe in Darwin's theory of evolution.
This documentary follows various migratory bird species on their long journeys from their summer homes to the equator and back, covering thousands of miles and navigating by the stars. These arduous treks are crucial for survival, seeking hospitable climates and food sources. Birds face numerous challenges, including crossing oceans and evading predators, illness, and injury. Although migrations are undertaken as a community, birds disperse into family units once they reach their destinations, and every continent is affected by these migrations, hosting migratory bird species at least part of the year.
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.
When a huge meteorite crashed into the earth 66 million years ago and caused the disappearance of the dinosaurs, some of the planet’s tiniest species survived the cataclysm, and—against all odds—eventually became some of the greatest giants to ever roam the earth. From the poles of the planet to the belly of the equator, this documentary sheds new light on four giant animals that are still a great mystery to science today: the Titanoboa snake, the Megalodon shark, the giant rhinoceros and the giant sloth.
Did Cartier dream of making a country from this land of a million birds? In his records of his exploration he certainly marvelled at seeing the great auks that have since disappeared from Isle aux Ouaiseaulx, the razor-bills and gannets that are gone from Blanc-Sablon, and the kittiwakes from Anticosti, all the winged creatures of all the islands which he described as being "as full of birds as a meadow is of grass". And that's not even counting the countless snow geese.
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.
Costa Rica's motto is Pura Vida - Pure Life - and this deceptively small country is bursting with some of the most spectacular wildlife and pristine ecosystems in the world. All this diversity thrives, in part, thanks to one surprising little creature: hummingbirds. Venture across Costa Rica's wild and rugged landscapes, from volcanic peaks to coastal jungle to misty cloud forests and discover the nation's dazzling diversity of hummingbirds. Watch how these tiny birds play an outsize role in maintaining some of the richest and wildest environments on Earth, where a whole community of creatures, such as macaws and monkeys, enjoys The Hummingbird Effect.
A mechanic discovers the fossil of a huge carnivorous dinosaur, unleashing a war between scientists, mayors and neighboring towns to keep “the biggest dinosaur in the world.” Among bone thefts, replicas and a mayor obsessed with creating Dinolandia, anything goes when it comes to surviving.
A scientist explains how the savagery and efficiency of the insect world could result in their taking over the world.
In 1858 Charles Darwin struggles to publish one of the most controversial scientific theories ever conceived, while he and his wife Emma confront family tragedy.
