Part 1: In The Grip Of The Ocean

S1 E1: In the middle of the Pacific Ocean, around 1000 km to the west of South America, there is a group of volcanic islands. The Galapagos Archipelago. The islands are considered the cradle of evolution. Nowhere else you could find such a rare variety of animals, including diving iguanas, giant tortoises with snake-like necks, and albatrosses which you normally expect on the open ocean.
