Darwin's Darkest Hour (2 hrs) - Tuesday, October 6NOVA and National Geographic Television present the extraordinary human drama that led to the birth of the most influential scientific theory of all time. Acclaimed screenwriter John Goldsmith brings to life Charles Darwin's greatest personal crisis: the anguishing decision over whether to "go public" with his theory of evolution. Darwin, portrayed by Henry Ian Cusick (
Lost), spent years refining his ideas and penning his "Big Book,"
On 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, portrayed by Frances O'Connor, 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.
Hubble's Amazing Rescue - Tuesday, October 13
In the spring of 2009, NASA sent a shuttle crew on a risky mission to service the Hubble Space Telescope for the

last time. Hubble has enthralled scientists and the public by capturing deep views of the cosmos and a wealth of data from distant galaxies. It has helped lead the search for alien planets and is a key tool in cosmology's quest to investigate and map the universe's mysterious dark matter. The astronaut servicing team carried out the first-ever in-space repairs of Hubble's defective instruments, a task that required ingenious engineering fixes and the most intensive NASA spacewalk ever. From training to launch,
NOVA presents the inside story of the mission and the extraordinary challenges faced by the rescue crew.
Why Do We Dream? - Tuesday, October 20
What are dreams and why do we have them? Are they a window into a hidden realm within us? Science is only just beginning to understand.
NOVA joins the leading dream researchers and witnesses the extraordinary experiments they use to investigate the world of sleep. From human narcoleptics to sleepwalking cats, from recurrent nightmares to those who can't dream, each sequence contains a vital clue to the question these scientists are pursuing: Why do we dream?
Becoming Human: Unearthing Our Earliest Ancestors - Tuesday, November 3, 10 & 17
NOVA presents a three-part, three-hour special - investigating explosive new discoveries that are transforming the picture of how we became human. The first pro

gram explores fresh clues about our earliest ancestors in Africa, including the stunningly complete fossil nicknamed "Lucy's Child." These three-million- year-old bones from Ethiopia reveal humanity's oldest and most telltale trait - upright walking rather than a big brain. The second program tackles the mysteries of how our ancestors managed to survive in a savannah teeming with vicious predators, and when and why we first left our African cradle to colonize every corner of the Earth. In the final program,
NOVA probes a wave of dramatic new evidence, based partly on cutting-edge DNA analysis, that reveals new insights into how we became the creative and "behaviorally modern" humans of today, and what really happened to the enigmatic Neanderthals who faded into extinction. Shot "in the trenches" where discoveries were unearthed throughout Africa and Europe, each hour of
Becoming Human unfolds with a forensic investigation into the life and death of a specific hominid ancestor, such as "Lucy's Child."
Lizard Kings - Tuesday, November 24
Though they may look like dragons and inspire stories of man-eating, fire-spitting monsters with long claws, razor-sharp teeth and muscular, whip-like tails, these creatures are actually monitor lizards, the largest lizards to walk the planet
. With their acute intelligence - including the ability to plan ahead - these lizards are a very different kind of reptile, blurring the line between reptiles and mammals. And even though these bizarre reptiles haven't changed all that much since the dinosaurs, they are a very successful species, versatile at adapting to all kinds of settings
. Lizard Kings will look at what makes these tongued reptiles so similar to mammals and what has allowed them to become such unique survivors
. But while the creatures can find their way around many different habitats, finding them is no easy task. Natural loners, and always on guard, they sense anything or anyone from hundreds of feet away
. NOVA follows expert lizard hunter Dr. Eric Pianka as he tracks the elusive creatures through Australia's heartland with cutting-edge "lizard cam" technology for an unparalleled close encounter with these amazingly versatile "living dragons."
What Darwin Never Knew (2 hours) - Tuesday, December 29
Earth teems with a staggering variety of animals, including 9,000 kinds of birds, 28,000 types of fish, and more than 350,000 species of beetles. What explains this explosion of living creatures - 1.4 million different species discovered so far, with perhaps another 50 million to go? The source of life's endless forms was a profound mystery until Charles Darwin's revolutionary idea of natural selection, which he showed could help explain the gradual development of life on Earth. But Darwin's radical insights raised as many questions as they answered. What actually drives evolution and turns one species into another? And how did
we evolve?
Now, on the 150th anniversary of Darwin's
On the Origin of Species,
NOVA reveals answers to the riddles that Darwin couldn't explain. Stunning breakthroughs in a brand-new science - nicknamed "evo devo" - are linking the enigma of origins to another of nature's great mysteries, the development of an embryo. To explore this exciting new idea,
NOVA takes viewers on a journey from the Galapagos Islands to the Arctic, and from the Cambrian explosion of animal forms half a billion years ago to the research labs of today. Here scientists are finally beginning to crack nature's biggest secrets at the genetic level. And, as
NOVA shows in this absorbing detective story, the results are confirming the brilliance of Darwin's insights while exposing clues to life's breathtaking diversity in ways the great naturalist could scarcely have imagined.
