0000551 - The Oldest Known Living Thing on Earth

In the harsh and unforgiving environment of the Eastern Mojave Desert of California, there exists an unassuming yet extraordinary organism that holds the remarkable distinction of being the oldest known living thing on Earth: a creosote bush named King Clone. Estimated to be between 11,700 and 13,000 years old, this ancient plant stands as a testament to the tenacity of life and the passage of countless millennia.

Creosote bushes, scientifically known as Larrea tridentata, are well-adapted to the arid conditions of the desert. Their small, evergreen leaves are coated with a waxy resin that helps them conserve water. The roots of creosote bushes can grow up to 50 feet long, allowing them to absorb moisture from deep below the surface.

King Clone is not a single plant, but rather a vast interconnected network of genetically identical clones that spread clonally, forming a single massive plant. This interconnectedness allows the plant to withstand harsh conditions and share resources, contributing to its exceptional longevity.

The creosote bush is a keystone species in the desert ecosystem, providing food and shelter for a variety of animals. Its roots help stabilize the soil, preventing erosion. The plant also releases volatile organic compounds that contribute to the formation of clouds and, ultimately, rainfall in the desert.

The ancient age of King Clone has been determined through a combination of radiocarbon dating and dendrochronology, a technique that involves counting and analyzing tree rings. Scientists have found that King Clone's central trunk has lived for over 11,700 years. However, the plant's root system, which is believed to be even older, may have been thriving in the desert for up to 13,000 years.

The survival of King Clone for such a remarkable length of time is a testament to the resilience and adaptability of life, even in the most unforgiving environments. It serves as a reminder of the interconnectedness of all living things and the vital role that plants play in maintaining the balance of our planet.
