This fall, NOVA celebrates the 200th anniversary year of Darwin's birth and the 150th anniversary of the publication of his famous book the Origin of Species with three evolution-themed programs. Each film will approach the topic of evolution in a different way.

To kick off NOVA's fall season (watch Friday, October 9th 10pm on PBS-HD), Henry Ian Cusick (Lost) and Frances O'Connor (Mansfield Park) star in Darwin's Darkest Hour, a two-hour scripted drama that presents the remarkable story behind the birth of Darwin's radically controversial theory of evolution and reveals his deeply personal crisis: whether to publish his earthshaking ideas, or to keep quiet to avoid potential backlash from the Church.

Darwin spent years refining his ideas and penning his book the Origin of Species. 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 all of his work to obscurity-his voyage on the Beagle, his adventures in the Andes, the gauchos and bizarre fossils of Patagonia, the finches and giant tortoises of the Galapagos.

But to come forward with his ideas risked the fury of the Church and perhaps a rift with his own devoted wife, Emma, who was a strong believer in the view of creation and honestly feared for her husband's soul. Darwin's Darkest Hour is a moving drama about the birth of a great idea seen through the inspiration and personal sufferings of its brilliant originator.

In November, NOVA premieres Becoming Human, a three-part special on human evolution. The series combines interviews with worldrenowned anthropologists and paleoanthropologists and the most recent, groundbreaking discoveries with vivid images of our earliest ancestors to present a comprehensive picture of our human past.

Then, on December 29, What Darwin Never Knew reveals answers to evolutionary questions that even Darwin couldn't explain. Scientists are beginning to expose nature's biggest secrets on the genetic level, with the hope of one day answering the crucial question: How does evolution really work?
