Marinoan glaciation

The Marinoan glaciation was a significant ice age that occurred around 635 million years ago during the late Precambrian period. It is characterized by global-scale glaciation, where ice covered much of the Earth, potentially reaching equatorial regions. This event is associated with the "Snowball Earth" hypothesis, suggesting extreme climate changes. It likely played a key role in shaping the planet's climate and fostering evolutionary developments, paving the way for the emergence of complex life in the subsequent Ediacaran and Cambrian periods. The Marinoan glaciation highlights Earth's dynamic climate history and its impact on life evolution.
