It is rather difficult to imagine, but approximately 635 million years ago, ice may have covered a vast portion of our planet in an event called "Snowball Earth." According to the Snowball Earth hypothesis, the massive ice ...

How do we begin to understand what early life was like on Earth about 700 million years ago as our planet shifted from an oxygen-free and probably ice-covered realm to the oxygen-rich world that we know today?
