"Breakthrough Fossil Discovery Reveals Photosynthesis Origin 1.75 Billion Years Ago"

Scientists have discovered fossils dating back 1.75 billion years, providing evidence of ancient oxygenic photosynthetic structures that predate previous findings by over a billion years. This discovery, detailed in a study published in Nature, could shed light on the origins of life on Earth and the Great Oxygenation Event, which filled the atmosphere with oxygen and allowed diverse life forms to emerge. The fossils were found in the McDermott Formation in Australia, and the research highlights the significant impact these early photosynthetic organisms had on the planet's atmosphere and biosphere.

"Breakthrough Fossil Discovery Pushes Origins of Photosynthesis Back 1.75 Billion Years"

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.
