New Frontiers / Episode 3DVD - 2005
For billions of years, life existed only in the Earth's oceans. But about 350 million years ago, some of those earliest life forms began to explore new frontiers on land. They could breath oxygen from the air and were able to support weight on land. Over the next hundred million years, these life forms would spread across the globe.
