Earth’s longest survivors reveal how life persists across millennia and how scientists measure ages.
Some of Earth's oldest living organisms are microbial mats over 2.5 billion years old, predating dinosaurs by millennia.
Bristlecone pines can survive centuries of drought by absorbing scarce groundwater via deep, ancient root networks.
Nostoc cyanobacteria form gigantic, planet-spanning colonies that reproduce as gas-vesicle–hardened filaments across continents.
Giant tortoises carry microbes from their birth, enabling ultra-long digestion cycles that outlast many mammals’ lifespans.
