In a recent study, researchers delved into the genetic makeup of Jonathan, an Aldabra giant tortoise who holds the record as the oldest land animal known, at a remarkable age of at least 194 years. Led by Dr. Stephen Clark, a neuro-oncologist and chief scientist at the longevity organization Kallel, the team examined Jonathan’s genome to uncover insights into his extraordinary longevity. Their findings, published in the journal Science Advances, revealed that certain sections of Jonathan’s genome responsible for gene regulation matched those of much younger tortoises, indicating potential clues to his extended lifespan.
Jonathan resides in the vicinity of the governor’s residence in St. Helena, embodying a testament to longevity and resilience among land-dwelling creatures. The study sheds light on the remarkable genetic characteristics that may contribute to defying the aging process in these remarkable animals.
