Evolution questioned by today's Christian sects on Galapagos Islands

The Galapagos Islands -- 600 miles off the coast of Ecuador - are famed for the unique wildlife that inspired Charles Darwin's theory of evolution. But today these isolated islands are also home to several Christian sects, including Jehovah's Witnesses, Seventh Day Adventists and Mormons; many of whom question evolution and believe in a creationist approach to the origins of earth. Ruth Evans meets a Jehovah's Witness who also works as a naturalist guide on the islands to find out how he reconciles his faith with the tenets of biological science.
