Early complex life was limited to oxygen-rich seabed areas for hundreds of millions of years. This is much longer than scientists previously thought.

How life survived the most severe ice age in Earth’s history when the planet was covered in ice and snow? Glacial meltwater created oxygen-rich pockets in the ocean where primitive animals such as sponges could thrive. These oxygen oases were crucial for the survival and evolution of complex life forms which emerged after the ice age ended.
