'Extinct' Galapagos tortoise reappears

After 150 years of being "extinct," a species of giant tortoise may be on the verge of a comeback tour, scientists report on Jan. 9. The researchers "found" the lost species, called Chelonoidis elephantopus, by analyzing the genome of a closely related species which lives on Isabela Island, the largest of the Galápagos Islands in the Pacific Ocean.
