It is referred to as the Great Oxygenation Event. During this time, photosynthetic organisms evolved and begun utilizing sunlight for energy. They captured this energy into chemical energy. These organisms took up carbon dioxide and evolved oxygen into the atmosphere.
Explanation:
Oxygen levels in the atmosphere rose drastically as those of carbon dioxide and methane dropped. This increase of oxygen in the atmosphere also allowed the formation of an ozone layer that protects genetic material from UV light. This largely enabled organisms to conquer land.
