Ice as an Incubator

Surprisingly, ice may have provided a safe haven for the first chemical steps of life. Studies suggest that frozen environments can shield delicate biomolecules from destructive radiation, preventing them from breaking down too quickly. In fact, the unique structure of ice can even speed up essential chemical reactions by crowding molecules together. This opens up the intriguing possibility that early Earth’s icy regions—or even frozen moons elsewhere—could have served as incubators for the emergence of life.
