For generations, the dream of reading the genetic past has been bounded by the fragility of DNA itself — a molecule that time dissolves into silence. Now, by turning to proteins, the more durable biological messengers that DNA once instructed into being, researchers have reached back 21 to 24 million years into the life of an Arctic rhinoceros, recovering genetic information ten times older than any DNA record. The discovery does not promise resurrected dinosaurs, but it quietly expands the horizon of what the living world can still tell us about itself.
