Galapagos Tortoise 'Lonesome George' May Have Company


The death of Galápagos tortoise Lonesome George this summer was thought to mark the extinction of a subspecies, but a new study hints that the reptile may not have been the last of his kind after all.

Researchers from Yale University recently trekked to the northern tip of Isabella Island, the largest of the Galápagos, and collected DNA from more than 1,600 giant tortoises. The genetic samples showed that 17 of these tortoises were hybrids that had a parent like Lonesome George from the subspecies Chelonoidis abingdoni.

What's more, five of those hybrids were juveniles, suggesting purebred C. abingdoni tortoises may still be roaming a remote part of the island.
