Cyanobateria was the first organism with the ability to perform oxygenic photosynthesis and is thought to have converted the early reducing atmosphere into an oxidizing one, which dramatically changed the composition of life forms on Earth by provoking an explosion of biodiversity and leading to the near-extinction of oxygen-intolerant organism.
