Humans drove it to extinction about years ago but the Floreana Island tortoise is getting a second chance after scientists found reptiles with genes from the lost species living around a volcano on a neighboring island. Over time is right: Miller said it takes about 20 years for a tortoise to reach reproductive age, which means new generations might come slowly. But he emphasized this purebred tortoise is not the immediate goal; rather his team is aiming to whip up baby tortoises quickly and release them into the wild when they are big enough, repopulating Floreana Island.

While human interference is what wiped out the Floreana tortoise to begin with, it is also what has made this de-extinction project possible. When repatriated to Floreana Island, these tortoises can once again play their critical role as ecosystem engineers. Tortoises with ancestry from the Floreana species had saddleback-shaped shells, right, compared to the more dome-shaped shells of their relatives, at left.

Scientific Reports If everything works out, the team may be able to replicate their project with the extinct C. While the scientists were searching for tortoises on Isabela Island with Floreana ancestry, a similar search for Pinta tortoises did not turn up anything. For now, the researchers are focusing on the slow restoration of the Floreana tortoise.
