In the 1500s, there were about 250,000 Galápagos tortoises, but that number dropped by the 1800s when sailors began using the animals for their meat. Now, there are only an estimated 3,000 to 5,000 living in the wild and no known specimen of the Pinta subspecies.
The return of the Pinta depends on the success of the scientists' research and the eagerness of the 32 tortoises to reproduce.
Hopefully they find the research and breeding facility more conducive for baby-making than it sounds.
CORRECTION: A previous version of this article stated that the Galápagos tortoises are an extinct species. There are several subspecies of Galápagos tortoises, and Lonesome George is believed by many to have been the last of the Pinta giant tortoises.
