Prometheus, The Tree
In 1964, Prometheus, a Great Basin Bristlecone Pine, was the oldest known non-clonal organism on Earth. That year, a graduate student cut down the 5,000- year-old tree to examine its ring growth patterns and derive information about the climate. It is unclear who suggested that Prometheus be cut down, why the action was deemed necessary, and whether its impact was fully understood at the time. Methuselah is currently the oldest known living tree. How old is it?
