Methuselah is a 4,856-year-old [1] Great Basin bristlecone pine (Pinus longaeva) tree growing high in the White Mountains of Inyo County in eastern California. [2] [3] It is recognized as the non-clonal tree with the greatest confirmed age in the world. [4]
A rooted phylogenetic tree (see two graphics at top) is a directed tree with a unique node — the root — corresponding to the (usually imputed) most recent common ancestor of all the entities at the leaves of the tree. The root node does not have a parent node, but serves as the parent of all other nodes in the tree.
Edward Hitchcock's fold-out paleontological chart in his 1840 Elementary Geology. Although tree-like diagrams have long been used to organise knowledge, and although branching diagrams known as claves ("keys") were omnipresent in eighteenth-century natural history, it appears that the earliest tree diagram of natural order was the 1801 "Arbre botanique" (Botanical Tree) of the French ...
It is estimated to have over 5000 rings. If accurate, that would be more than 100 years older than the current record holder. Barichivich said "Only 28 percent of the tree is actually alive, most of which is in the roots, so when people walk across the nearby soil, they're actively damaging the last remaining living parts of the tree."

Layering occurs when a tree's branch comes in contact with the earth, and new roots sprout from the contact point. Other trees, such as coast redwoods and western red cedars are known to reproduce by layering. [6] The tree's age was determined by carbon-14 dating of the root system, which found roots dating back to 375, 5,660, 9,000, and 9,550 ...
The tree's stems live no more than 600 years, but its root system's age [75] [76] was established using carbon dating and genetic matching. [77] Elsewhere in the Fulu mountains, 20 spruces have been found older than 8,000 years. [78] Old Rasmus: 9,500: Norway spruce Picea abies: Sonfjället, Härjedalen: Sweden [79] Mongarlowe mallee: 3,000 ...

The roots require oxygen to respire and only a few species such as mangroves and the pond cypress (Taxodium ascendens) can live in permanently waterlogged soil. [50] In the soil, the roots encounter the hyphae of fungi. Many of these are known as mycorrhiza and form a mutualistic relationship with the tree roots. Some are specific to a single ...
