The tree's true age was revealed by carbon-14 dating its root system. According to a statement from Umeå University, scientists found four generations of spruce remains at the site, all with the same genetic makeup. Spruce trees can multiply with the root penetrating branches to produce exact copies of themselves, so while the individual trunk is younger, the organism has been cloning itself for at least 9,550 years.
