The series takes place after the extinction of the dinosaurs 65 million years ago and recreates animals of the Cenozoic with computer-generated imagery and animatronics. The first episode starts 49 million years ago, when Earth has fully recovered from the dinosaur extinction and is covered in a mysterious forest. This is a time that the world has almost forgotten - Germany was a hot sweaty jungle, birds ruled the earth and preyed on miniature horses and whales walked on land.

Located in an almost inaccessible chamber deep in a South African cave, the site required recruiting a special team of experts slender enough to wriggle down a vertical, pitch-dark, seven-inch-wide passage. Most fossil discoveries of human relatives consist of just a handful of bones. But down in this hidden chamber, the team uncovered an unprecedented trove—so far, over 1,500 bones—with the potential to rewrite the story of our origins". They may help fill in a crucial gap in the fossil record and tell us how Homo, the first member of the human family, emerged from ape-like ancestors like the famous Lucy. But how did hundreds of bones end up in the remote chamber? The experts are considering every mind-boggling possibility. Join us on the treacherous descent into this cave of spectacular and enigmatic finds, and discover their startling implications for the saga of what made us human.

Professor Diarmaid MacCulloch - one of the world's leading historians - reveals the origins of Christianity and explores what it means to be a Christian. In the first episode, he overturns the familiar story that it all began when the apostle Paul took Christianity from Jerusalem to Rome. Instead, he shows that the true origins of Christianity lie further east, and that at one point it was poised to triumph in Asia, maybe even in China. The headquarters of Christianity might well have been Baghdad not Rome, and if that had happened then Western Christianity would have been very different.

The nest is a new home for a million-strong colony of leafcutter ants from Trinidad. For a month, entomologist Dr George McGavin and leafcutter expert Professor Adam Hart capture every aspect of the life of the colony, using time-lapse cameras, microscopes, microphones and radio tracking technology.
