It may not look like much but scientists claim that this tree is the oldest in the world. Discovered in the Dalarna province of Sweden, the trunk upon which this spruce has grown is believed to date back nearly 10,000 years. “Spruce trees can multiply with root penetrating branches, meaning they can produce exact copies, or clones,” says Leif Kullman from Umee University. Scientists found four “generations” of spruce remains in the form of cones, and wood produced from the highest grounds of Fulu mountain. The age was tested by carbon dating in Florida.
