"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.
