A 194-year-old tortoise named Jonathan, an Aldabra giant tortoise, holds the record as the oldest-known land animal, surpassing most giant tortoises by about 100 years. Researchers delved into Jonathan’s genome in a recent study led by Dr. Stephen Clark, a neuro-oncologist and chief scientist at the longevity nonprofit Kallel. Their investigation revealed that sections of Jonathan’s genome responsible for gene regulation were comparable to those of much younger tortoises, shedding light on his remarkable longevity. The study’s findings were detailed in the journal Science Advances.
Jonathan resides on the grounds of the governor of St. Helena’s residence. The research on Jonathan’s genome provides insights into defying aging and longevity in tortoises, offering valuable information for understanding the aging process in these creatures.
