Discovering Earth's Oldest Organisms
Meet the science experts who study specimens of extreme longevity in both the plant and animal kingdoms, such as the 80,000-year-old root system of Pando (a colony of male quaking aspens), 11,000-year-old deep-sea sponges, and 400-year-old sharks. Learn about technologies used to determine age and longevity, including DNA sampling, growth rings, and radiocarbon dating. See how scientists located these long-lived species were and why and how they resist disease and aging. And delve into how scientists are using what they know about aged plants and animals to research how we can promote longevity in humans.
