    In the mid-19th century, a species of giant tortoise unique to Floreana Island in the Galapagos was thought to have become extinct. But conservationists believe they can bring back the species, almost 170 years after it vanished. A captive breeding programme has now started with 23 tortoises housed on Santa Cruz Island, California, with the aim of soon returning
