This image displays the distinct stripes of iron-rich and silica-rich rocks, known as Banded Iron Formations, located at Fortescue Falls in Karijini National Park, Western Australia.
c. 3-1.8 Billion BCE: Decoding Banded Iron Formations – A Geological Mystery

Examines Banded Iron Formations (BIFs), which reveal early oxygenation events on Earth, linking them to the rise of oxygenic photosynthesis by cyanobacteria and the subsequent atmospheric changes.

This image shows a shallow-water kelp forest off the coast of Southern California, where plants utilize oxygenic photosynthesis to transform sunlight into internal energy, like glucose.
c. 3.4 Billion BCE: The Evolution of Photosynthesis – Transforming Earth

Discusses the evolution of photosynthesis, highlighting its impact on Earth's atmosphere and life forms. It traces the development from early anoxygenic photosynthesis to the oxygen-producing photosynthesis by cyanobacteria, leading to the Great Oxidation event.
