How the Proterozoic Eon Actually Works
For those new to the Proterozoic Eon, it's essential to understand the basics. This eon is characterized by a significant increase in oxygen levels in the atmosphere, leading to the development of complex life forms. During this period, the Earth's oceans were home to the first multicellular organisms, setting the stage for the evolution of more complex species. The Proterozoic Eon also saw the emergence of the first supercontinents, such as Rodinia and Columbia, which played a crucial role in shaping the Earth's geology.
