9,500-Year-Old Tree Found In Sweden Is The World's Oldest Tree

The tree, named Old Tjikko, pictured on a less cold day, was found by a team of scientists during a 2004 census. It has been able to survive so long thanks to the process of vegetative propagation, which means it is able to effectively clone itself. While the visible portion of the 13ft tall tree is relatively new, its root system has been growing for almost ten thousand years. The parts of the root system that were sent to the United States dated back nearly 10,000 years, it is possible that other parts are older, locals told Aftonbladet.
