That title is rather clickbaity for a "science" magazine. Crucially, the tree prominently featured in the large picture is not 10,000 years old and only its root system originates from that period:<p>> Today Old Tjikko’s tree trunk is only five metres high. Although the spruce may have had many such trunks over the millennia, the tree's root system has survived all these years. No part of today’s living tree is as old as 9 500 years, but genetically, the tree is exactly the same individual as when it began to germinate.<p>Indeed if we allow equating the plant to the age and extent of its root system (genetically the same organism, although no part of the present plant is as old), I already found this other tree root system named "Pando" in Utah, USA, that is estimated to be up to 14,000 years old - making the Swedish spruce's claim to world's oldest dubious:<p><a href="https://en.wikipedia.org/wiki/Pando_(tree)" rel="nofollow">https://en.wikipedia.org/wiki/Pando_(tree)</a><p>Pando is also thought to be the largest and heaviest known single organism, covering 43 hectares and weighing 6,000 tons.
