In this new series, the veteran broadcaster explores the Galapagos, a collection of volcanic islands in the Pacific known for its extraordinary wildlife. More than 150 years after Charles Darwin formulated his ground-breaking theory of evolution on the remote archipelago, Attenborough explains how life on the islands has continued to evolve in biological isolation, examining how the ever-changing volcanic landscape has given birth to species and sub-species that exist nowhere else in the world. He begins by revealing how Galapagos rose from the ocean four million years ago.
