Summary:
- Bristlecone pines are ancient trees that can live for thousands of years, making them the oldest known living organisms on Earth.
- Researchers have studied the growth rings of these trees to learn about the climate conditions over many centuries, providing valuable insights into how the climate has changed over time.
- The longevity of bristlecone pines is attributed to their ability to adapt to harsh environmental conditions, such as high altitudes and limited water availability, which can help us understand how other organisms might adapt to climate change.
