Paleoproterozoic Era

The Paleoproterozoic Era, lasting from about 2.5 to 1.6 billion years ago, was a time of significant Earth's development. During this period, oxygen began accumulating in the atmosphere thanks to early photosynthetic life, leading to the Great Oxidation Event. This era saw the formation of large continental landmasses, formation of new minerals, and the emergence of complex, single-celled organisms. It set the stage for more advanced life forms and the Earth's evolving environment, marking a critical phase in Earth’s history when the atmosphere transformed from reducing to oxidizing conditions.
