Giant Galapagos tortoise extinct for 150 years might still be alive

A subspecies of the the giant Galapagos tortoise, Chelonoidis elephantopus, long thought to be extinct for more than 150 years, is now believed to might still exist, scientists say. Yale University researchers conducted a highly thorough genetic analysis of various Galapagos giant tortoises in the region, which allowed them to speculate that at least a few dozen specimens of the elusive Chelonoidis elephantopus might
