Fossil records tell us that about 250 million years ago, there wasn’t a tree on Earth that was designed to survive temperatures below freezing. They were all built for life in the tropics where it’s always warm, water is always liquid, and leaves are safe year ’round without fear of frost.

Today, there are trees across the globe that can avoid both the dangerous bubbles that would otherwise form inside their internal ‘plumbing’ and any ice crystal damage to their cells. Learn how these trees survive the winter in this episode of Minute Earth.
