Conservationists working around the largest volcano on the Galapagos Islands say they have found 30 giant tortoises partially descended from two extinct species, including that of the famed Lonesome George.
The Galapagos National Park and Galapagos Conservancy said that a young female has a direct line of descent from the Chelonoidis abingdonii species of Pinta Island.
The last of those tortoises was Lonesome George, who died in June 2012 and was believed to be more than 100 years old.
Another 11 males and 18 females were from the Chelonoidis niger line of Floreana Island.
The 45-member expedition was working around the Wolf Volcano on Isabela island.
It said pirates and whalers had taken tortoises from other islands in the archipelago and left them near the volcano.
Those found during the new expedition were hybrids descended from both the extinct and other species.
The Galapagos, whose variety of endemic species helped inspire Charles Darwin, held 15 closely related species of tortoise, according to the Conservancy, which estimates that 20,000–25,000 wild tortoises live on the islands today.
At least four of the species are now considered extinct.

The coronavirus pandemic is changing our world, fast. And we will do all we can to keep bringing you news and analysis throughout. But we are worried about maintaining enough income to pay our staff and minimal overheads.
Now, more than ever, we need a vibrant, independent media that holds the government to account and calls it out when it puts vested economic interests above human lives. We need a media that shows solidarity with the people most affected by the crisis – and one that can help to build a world based on collaboration and compassion.
We have been fighting against an establishment that is trying to shut us down. And like most independent media, we don’t have the deep pockets of investors to call on to bail us out.
