The Jurupa Oak tree first sprouted into life when much of the world was still covered in glaciers. It has stood on its windswept hillside in southern California for at least 13,000 years, making it the oldest known living organism, according to a study published today.
Scientists believe the tree, composed of a sprawling community of cloned bushes, is the oldest living thing because it has repeatedly renewed itself to ensure its survival through successive periods of drought, frost, storms and high winds.
The Jurupa oak, named after the Jurupa Hills in California’s Riverside County, belongs to a species called Quercus palmeria, or Palmer’s Oak. It was this fact that first alerted scientists to the idea that all was not what it seemed when it came to this particular stand of scrubby oak bushes.
