|A Pinus longaeva, showing its age|
The oldest known bristlecone is a tree called "Methuselah", growing in eastern California. At the time it first sprouted, around 2800 BC, the Neolithic period was barely over. Mesopotamians had just invented the city, the Egyptians were developing hieroglyphic writing, and the potter's wheel was the height of technology. Imagine -- there is a single living thing that would remember all of that, if it could!
