Archaean biogeochemistry

Archaean biogeochemistry refers to the study of how life and the environment interacted during the Archaean Eon, about 4 to 2.5 billion years ago. During this time, simple microbial life thrived in a very different Earth, where conditions were extreme, with high temperatures and a lack of oxygen. These early organisms played a crucial role in shaping the planet’s chemistry, influencing the atmosphere and the oceans. Their processes, such as photosynthesis and methane production, helped create conditions that allowed for more complex life to eventually develop, laying the foundation for the Earth’s modern ecosystem.
