'This also shows the importance of using museum collections to understand the past,' Adalgisa Caccone, the senior author of the study and a lecturer in ecology and evolutionary biology at Yale University, said in a statement. The GalГЎpagos Archipelago is well known for its distinct species, which were studied by Charles Darwin and helped contribute to his theory on evolution. There are believed to be 15 species of GalГЎpagos tortoises, according to the nonprofit GalГЎpagosВ Conservancy. Though another 'fantastic giant tortoise' has not been found since Fernanda, there have been encouraging signs, like tracks and feces, suggesting 2 to 3 other tortoises may be on the island. While tortoises don't swim, they can float or be transported during storms. Once she was found, researchers thought Fernanda may have been native to a different GalГЎpagos island and somehow ended up on Fernandina. 'We really did not expect that there were any tortoises living on Fernandina Island, although there were rumors of signs of tortoises there over the decades.' 'That Fernanda was found at all was a huge surprise,' Jensen said. Their analysis indicated the two tortoises were genetically distinct from other species of GalГЎpagos tortoises and are from the same lineage. Researchers sequenced the genomes of both Fernanda and the 1906 specimen, which was part of the California Academy of Sciences collection. Galapagos ConservancyДЇernanda was collected and placed in captivity at the GalГЎpagosВ National Park Tortoise Center.

Her growth was stunted, which the researchers said could explain why her physical traits weren't quite as pronounced as the specimen found in 1906.ДЇernanda the 'fantastic giant tortoise' at the Santa Cruz Giant Tortoise Breeding Center in Galapagos.

The specimen differed from other GalГЎpagos tortoises due to the shape of its shell, which flared out along the edge, and prominent 'saddlebacking,' or a raised, saddle-like shape, towards the front.Д«ut another 'fantastic giant tortoise' was never found, with the species long considered extinct - that is, until Fernanda.ДЇernanda, who researchers believe is at least 50 years old, was discovered in 2019 on an isolated patch of vegetation that was cut off from the main vegetated area of the island by lava flows.

The first specimen of Chelonoidis phantasticus, also called 'the fantastic giant tortoise,' was discovered on Fernandina Island in 1906 and collected by explorer Rollo Beck. 'To find that a species of GalГЎpagos tortoise that was thought to be extinct for over 100 years is not in fact extinct, but lives on, was truly amazing,' Jensen said. Jensen was the co-first author of the paper along with Stephen Gaughran, a postdoctoral research fellow in ecology and evolutionary biology at Princeton University. 'The significance of the find is huge,' Evelyn Jensen, a lecturer in molecular ecology at Newcastle University, told Insider.
