A 194-Year-Old Tortoise, World’s Oldest Land Animal, May Hold Clues to Longer Life
- In a study published Wednesday in Science Advances, researchers identified 287 unique gene variants in Jonathan, a 194-year-old Aldabra giant tortoise, that may explain his extreme longevity.
- Jonathan, the world's oldest known living land animal, arrived on the British Overseas Territory of St. Helena in 1882 as a gift to Sir William Grey-Wilson and has lived at the governor's residence ever since.
- Analysis reveals that in 272 of Jonathan's genes tied to mitochondria, the chemical switches stayed as orderly as in a youngster, according to study co-author Stephen Clark, echoing patterns in long-lived humans.
- The Kallel Foundation aims to translate these evolutionary insights into practical, affordable treatments for everyday people while continuing to explore genetic mechanisms across long-lived species.
- Benjamin Vaisvil, co-lead author, cautioned that researchers "cannot say for certain that what we found is the reason for his longevity," noting the study involved only one exceptionally old tortoise.

Jonathan the turtle, who lives on the British territory of Saint Helena in the South Atlantic, is the world's longest-living land animal. Scientists have discovered the secret to Jonathan's longevity. It was found that his genes have barely aged over nearly two centuries. On the 7th (local time), the U.S. longevity research institute Kalel announced to international academics that they had "identified 287 gene variations in Jonathan, the longest…
It is known that the giant turtles Aldabra live for over 100 years, but Jonathan has far exceeded this age.

Scientists have sequenced their genome for the first time, hoping that the world's oldest terrestrial animal can offer clues about the genetics of longevity.
The oldest known terrestrial animal in the world – a huge turtle named Jonathan Aldabra –, whose age is estimated at about 194 years, probably owes its extraordinary longevity to a combination of genetic traits and the ability to maintain the functioning of key cellular systems in a more "young" way, scientists have discovered. ...
