Recognized as the world's oldest known land animal, Jonathan hatched around 1832 in the Seychelles. Researchers analyzed his DNA to uncover biological secrets behind his extreme longevity, identifying 287 unique gene variants associated with DNA repair and defenses against aging. Experts hope these genetic insights into his stable gene switches could eventually lead to human treatments and a better understanding of how to resist aging.Why it mattersJo
