Short summary

How could plant life, that needs light to survive, live on a planet covered with ice? Such a situation is thought to have existed during what are called the Snowball Earth events over 600 million years ago. Here we find that ice shadows, regions where ice has difficulty flowing into, may have a played a role in that survival of early plant life.
