40 - 16: Australia's First 4 Billion Years - Life Explodes

How did life storm the beaches and dominate planet Earth? Ancient Australian fossils offer clues. While the oceans were teeming, the world above the waves remained an almost lifeless wasteland -- until the Silurian period, when the conquest of the land began. 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. Join NOVA's prehistoric adventure as four-legged animals walk onto dry land, with the planet poised for disaster.
