A recent discovery has revealed that a 2-billion-year-old rock is home to living microbes. These ancient organisms provide valuable insights into early life on Earth and its evolution. Researchers believe that studying these microbes can help understand the conditions that supported life billions of years ago. This finding may also have implications for the search for extraterrestrial life, as it demonstrates the resilience of life in extreme environments. Such research continues to deepen our knowledge of biological history.
