Pando, a colony of quaking aspen, is one of the oldest-known clonal trees. Recent estimates of its age range up to 14,000 years old, and 18,000 years by the latest (2024) estimate. [1] It is located in Utah, United States. This is a list of the oldest-known trees, as reported in reliable sources. Definitions of what constitutes an individual ...
Fossils of plants from the early Devonian show that a simple form of wood first appeared at least 400 million years ago, at a time when all land plants were small and herbaceous. [87] Because wood evolved long before shrubs and trees, it is likely that its original purpose was for water transport, and that it was only used for mechanical ...
All life on Earth can be traced back to a Last Universal Common Ancestor, or LUCA—and it likely lived on Earth only 400 million years after its formation.
