Genetic tests have confirmed that a giant tortoise found in the Galapagos Islands is from a species scientists thought had become extinct more than a century ago.

The remains of a male specimen from 115 years ago allowed Yale University geneticists to determine that the female is indeed a Chelonoidis phantasticus, also known as Fernandina giant tortoise
