Tortoise species thought to be extinct still lives, genetic analysis reveals

G. Becky tortoises, above, are native to Isabela Island in the Galapagos chain and have more domed shape shell. The tortoise below is a hybrid with C. elephantopus, a species native to Floreana Island some 200 miles away and thought to be extinct. Genetic analysis of tortoise population on Isabela Island suggests purebred individuals of C. elephantopus must still be alive on Isabela.
