Scientists have made a discovery that points to the oldest traces of photosynthesis on Earth. A fossil of bacteria, nearly 2 billion years old, was found, and research has shown that it was capable of this key life process.
Photosynthesis is crucial for our existence as it provides us with the oxygen necessary for respiration. It is a process in which sunlight is used to convert carbon dioxide and water into oxygen and glucose. This fossil of bacteria is the oldest evidence of this process, which means that photosynthesis was present on Earth much earlier than previously thought.
This discovery is groundbreaking for our understanding of the evolution of life on Earth. Previous theories suggested that the first life forms capable of photosynthesis appeared around 1.2 billion years ago. However, this finding indicates that this process may have started nearly 2 billion years ago.
Scientists are excited about this discovery and emphasize that it will enable them to better understand the development of life on our planet. Thanks to this research, we can gain a better understanding of how photosynthesis has influenced the development of various organisms and ecosystems on Earth.
