Of all the continents on Earth, none preserves a more spectacular story of our planet's origins than Australia. NOVA's four-part "Australia's First 4 Billion Years" takes viewers on a rollicking adventure from the birth of the Earth to the emergence of the world we know today. With help from host and scientist Richard Smith, we meet titanic dinosaurs and giant kangaroos, sea monsters and prehistoric crustaceans, disappearing mountains and deadly asteroids. Epic in scope, intimate in nature, this is the untold story of the land "down under," the one island continent that has got it all. Join NOVA on the ultimate Outback road trip, an exploration of the history of the planet as seen through the window of the Australian continent.

Part 1: Awakening
What can Australia reveal about how Earth was born and how life took hold? Join NOVA and host Dr. Richard Smith as they journey back to the very beginning of the Australian story in "Awakening." The first stop is Western Australia, around four and a half billion years ago, where we encounter an Earth shortly after its fiery birth. Hidden in the red hills of Australia are clues to the mysteries of when the Earth was born, how life first arose, and how it transformed the planet. Experts unveil how the earliest forms of life—an odd assortment of bacterial slime—flooded the atmosphere with oxygen, sparking the biological revolution that made animal life possible. It is the beginning of the great drama of life on Earth.

Part 2: Life Explodes
How did life storm the beaches and dominate planet Earth? Ancient Australian fossils offer clues in "Life Explodes." Half a billion years ago, Australia was still part of the super-continent Gondwana. The oceans were teeming with weird and wonderful animals, but the world above the waves remained an almost lifeless wasteland. All that was about to change, though. Host Richard Smith introduces Earth's forgotten pioneers: the scuttling arthropod armies that invaded the shores and the waves of green revolutionaries whose battle for the light pushed plant life across the face of a barren continent. Evolution continued underwater as well, with armor-plated fish experimenting with teeth, jaws, sex, and lungs. NOVA's prehistoric adventure continues with four-legged animals walking onto dry land—and the planet poised for disaster.

Part 3: Monsters
"Monsters" begins Down Under at the dawn of the Age of Dinosaurs. Host Richard Smith comes face-to-face with the previously unknown reptilian rulers of prehistoric Australia. NOVA resurrects the giants that stalked the Great Southern Land and discovers that some of these animals were among the largest ever to have walked the Earth. Others were some of the most dangerous. In the dry desert heart, scientists unearth an ancient inland ocean full of sea monsters. Opal fossils of some of these beasts paint a colorful picture of the exotic seascape, where long-necked plesiosaurs snacked on shelled creatures that grew as large as truck tires. The most fearsome was Kronosaurus, with a skull twice as long as T. rex. But reptiles didn't have the world all to themselves. Mammals like the enigmatic platypus lived alongside them, ready for their moment in the sun.

Part 4: Strange Creatures
In the wake of the catastrophic asteroid impact believed to have wiped out the dinosaurs, Australia was set adrift on a lonely voyage across southern seas. With host Richard Smith, NOVA travels the walkabout continent to uncover how it became the strange land it is today. In this final episode, "Strange Creatures," NOVA traces the last 65 million years, revealing the events that shaped the Australia we know today. Prehistoric jungles retreated, replaced by eucalypt forests, grasslands, and deserts. When humans first arrived, giant marsupials dominated the land and the Great Barrier Reef was yet to form. This is a tale of calamity and conquest; how a conspiracy of climate, biology, and geology shaped the Earth we now call home.
