DURATION: 1 HOUR
David Attenborough asks three key questions: how and why did Darwin come up with his theory of evolution? Why do we think he was right? And why is it more important now than ever before?

David starts his journey in Darwin’s home at Down House in Kent, where Darwin worried and puzzled over the origins of life. He goes back to his roots in Leicestershire, where he hunted for fossils as a child and where another schoolboy unearthed a significant find in the 1950s, and he revisits Cambridge University, where both he and Darwin studied and where many years later the DNA double helix was discovered, providing the foundations for genetics.

At the end of his journey in the Natural History Museum in London, David concludes that Darwin’s great insight revolutionised the way in which we see the world. We now understand why there are so many different species, and why they are distributed in the way they are. But above all, Darwin has shown us that we are not set apart from the natural world, and do not have dominion over it. We are subject to its laws and processes, as are all other animals on earth to which, indeed, we are related.

This two-hour scripted drama tells the remarkable story behind the unveiling of the most influential scientific theory of all time, Charles Darwin’s theory of evolution by natural selection. The program is a special presentation from NOVA and National Geographic Television, written by acclaimed British screenwriter John Goldsmith and directed by John Bradshaw.

Darwin, portrayed by Henry Ian Cusick (Lost), spent years refining his ideas and penning what he called his “big book.” Yet, daunted by looming conflict with the orthodox religious values of his day, he resisted publishing–until a letter from naturalist Alfred Wallace forced his hand. In 1858, Darwin learned that Wallace was ready to publish ideas very similar to his own. In a sickened panic, Darwin grasped his dilemma: To delay publishing any longer would be to condemn his greatest work to obscurity–the brilliant argument he had pieced together with clues from his voyage on the Beagle, his adventures in the Andes, the bizarre fossils of Patagonia, the finches and giant tortoises of the Galapagos, as well as the British countryside. But to come forward with his ideas risked the fury of the Church and perhaps a rift with his own devoted wife, Emma, portrayed by Frances O’Connor (Mansfield Park, The Importance of Being Earnest), who was a devout Christian.

“Darwin’s Darkest Hour” is a moving drama about the genesis of a groundbreaking theory seen through the inspiration and personal sufferings of its originator.
