"Breakthrough Fossil Discovery Pushes Origins of Photosynthesis Back 1.75 Billion Years"
TL;DR Summary
Scientists have discovered fossilized bacteria in Australia and Canada that suggest photosynthesis may have started 1.2 billion years earlier than previously thought, potentially dating back to 1.7 billion years ago. This finding could significantly alter our understanding of the timeline for the development of complex life on Earth, which is closely tied to the history of photosynthesis and the Great Oxygenation Event that filled Earth's atmosphere with oxygen.
