Jonathan the giant tortoise's DNA reveals longevity secrets

Researchers studying Jonathan, a 194-year-old Aldabra giant tortoise and the world's oldest living land animal, have identified genetic markers that may offer insights into the aging process. A study published in Science Advances analyzed the tortoise's genome and epigenome to understand how he has maintained cellular health for nearly two centuries.

Scientists identified 287 unique genetic variants associated with protection against cellular damage, efficient DNA repair, and reduced inflammatory processes. The analysis also highlighted the tortoise's ability to maintain stable gene activity and mitochondrial function, whereas such control typically degrades in other species, including humans, during the aging process.

Jonathan currently resides on the island of Saint Helena in the South Atlantic. While the findings provide a significant biological roadmap for studying longevity, researchers noted that further study is required to determine if these mechanisms could be applied to human anti-aging therapies.
