Captured: The Moment Photosynthesis Changed the World

This informational text resource is intended to support reading in the content area. Geologists have made an important discovery about the origins of photosynthesis. According to evidence in South African rocks, before organisms were using water as the electron source for photosynthesis, they were using manganese - these rocks formed in anoxic conditions, but contain oxidized manganese. This evolution of photosynthetic organisms, which released atmospheric oxygen, laid the groundwork for more complex life forms, such as animals, to come into existence.
