At 194, Jonathan the Giant Tortoise Offers a Rare Window Into Aging
Jonathan, believed to be the worldās oldest living land animal, is drawing fresh attention after researchers linked his extraordinary longevity to biological traits that may help explain how some species resist age-related decline. The findings do not promise a human anti-aging breakthrough, but they sharpen scientific interest in the cellular and evolutionary mechanisms that allow certain animals to remain healthy for more than a century. For climate and conservation scientists, Jonathan also underscores the value of protecting long-lived species whose biology may hold clues to resilience in a warming world.
