In an evolutionary burst known as the Cambrian Explosion, complex animals rapidly appeared in the oceans, laying the foundations for almost every major animal group alive today. Tristan Hughes is joined by the mighty Henry Gee to explore biology’s 'Big Bang'. What triggered this extraordinary leap in evolutionary complexity? Why did creatures with eyes, shells and limbs emerge so suddenly in the fossil record? And what can the Cambrian Explosion reveal about the origins of animal life and the history of our planet?
