A 194-year-old tortoise named Jonathan, an Aldabra giant tortoise, holds the title of being the oldest-known land animal, surpassing the typical lifespan of giant tortoises by about a century. Researchers delved into Jonathan’s genetic makeup in a recent study led by Dr. Stephen Clark from the longevity nonprofit organization Kallel. Their investigation unveiled that specific segments of Jonathan’s genome responsible for gene regulation matched those of much younger tortoises, providing insight into his remarkable longevity. The findings were documented in the journal Science Advances.
Jonathan resides on the premises of the residence of the governor of St. Helena, showcasing his extraordinary lifespan. The study sheds light on the genetic factors contributing to Jonathan’s exceptional longevity, offering valuable lessons on defying the aging process.
