Dawn of the OceanDVD
Take a time trip 4 billion years into the past and wonder at the dawn of the ocean. Although scientist might have pinpointed the date when the oceans came into being, there is so much more that remains in the dark. Where exactly did water come from? How did marine life get started? What were the first complex life forms? Far from a stodgy lecture, this National Geographic special takes a fun approach to understanding this vast living organism that is the ocean.
