Did Life Begin in the Cold? New Experiments Point to an Icy Origin Most origin-of-life scenarios focus on environments such as drying and rewetting surfaces on land or hydrothermal vents on the ocean floor. This study suggests that icy regions could also have been significant. On the early Earth, freeze/thaw cycles likely occurred repeatedly over long timescales. Source:SciTechDaily @EverythingScience
