   194-Year-Old Tortoise Genome Sequenced

   Scientists have sequenced the genome and epigenome of Jonathan, an Aldabra giant tortoise estimated to be 194 years old and recognized as the oldest known land animal on the planet. Living on the island of St. Helena, the geriatric reptile has survived nearly two centuries of historical transformations and wars. Researchers investigating his extreme longevity discovered stable gene switches and youthful orderliness in promoters governing mitochondrial energy production. This genetic stability suggests that protecting gene regulation from entropy could offer valuable clues for understanding human aging and extending healthspan.

   Why it matters

   Jonathan's survival across nearly two centuries provides a rare biological window into extreme longevity among land animals. While the oceans hold creatures like glass sponges and Greenland sharks living for centuries, terrestrial animals face different physiological pressures. Vanderbilt-led researchers examined how his biological systems maintain youthful order over an extraordinarily long span.

   What is confirmed

   • Jonathan is an Aldabra giant tortoise estimated to be 194 years old.
   • He is recognized as the oldest known land animal on the planet.
   • A Vanderbilt-led team sequenced his genome and epigenome on St. Helena.
   • The study revealed stable gene switches and youthful orderliness in promoters governing mitochondrial energy production.

   Still unconfirmed

   • Jonathan's specific genetic mechanisms could directly unlock anti-aging treatments or skincare routines for humans.

   What to watch next

   • Further publication of research details from the Vanderbilt-led sequencing team
   • Additional comparative studies examining other long-lived reptile genomes
