The oldest living thing on Earth is considered to be a Great Basin Bristlecone Pine (Pinus longaeva).
Here's a more detailed breakdown:
- Species: Pinus longaeva (Great Basin Bristlecone Pine)
- Location: American West, specifically in high-altitude regions of California, Nevada, and Utah.
- Age: One known tree has been measured to be over 4,850 years old.
While other organisms like clonal colonies (e.g., Pando aspen clone, some fungi) may be older as a collective genetic unit, the Bristlecone Pine represents the oldest individual living tree with a single continuous stem.
