NOVA S40E16 - Australia's First 4 Billion Years: Life Explodes

Episode Overview

How did life conquer the shores and thrive on Earth? "Life Explodes" delves into ancient Australian fossils for answers. Over 500 million years ago, Australia was part of the supercontinent Gondwana. The oceans brimmed with bizarre creatures, while the land remained nearly devoid of life. However, this was on the brink of transformation. Hosted by Richard Smith, the episode reveals the early pioneers: swarming arthropods that crawled onto land and vibrant plants battling for sunlight across a barren terrain. Underwater, armored fish began evolving with teeth, jaws, reproduction methods, and lungs. The prehistoric journey culminates with four-legged beings emerging onto land, heralding a looming crisis for the planet.
