In the lightless depths of Arctic waters, a creature has been quietly outliving civilizations—the Greenland shark, whose 400-year lifespan has long defied biological convention. For the first time, scientists have mapped its complete genome, uncovering a paradox at the heart of its longevity: a genome twice the size of ours, dominated by unstable 'jumping genes' that the shark appears to have tamed and turned into tools for self-repair. What emerges is not merely a portrait of an extraordinary animal, but a new chapter in humanity's oldest inquiry—how, and why, we age.
