From a 50 million-year deep freeze to the two million-year volcanic eruption that wiped out 90 percent of life, and the equally prolonged downpour that made the planet hospitable again, Earth (Ancient Earth in the U.S.) chronicles a selection of major milestones in the four and a half billion-year story of our planet.
Narrated by Chris Packham and brought to life by mesmerising visual effects, the five-part BBC nature series takes us back to a time when the sky and the seas were sepia-tinted, and giant fungi dominated the landscape.
