Volcanoes Helped Life Survive During the Ice Age

Where did organisms turn when it was freezing during the ice ages? According to National Geographic, volcanoes may have been a refuge for plants and animals in need of some warmth. Scientists who mapped the number of plants, fungi, and invertebrates in relation to geothermal spots in Antarctica found the number of species was greatest near such sites. Their study, published this week in the Proceedings of the National Academy of Sciences, could help explain how life survived the ice age in Antarctica and suggests species clustered around volcanoes and then relocated during warmer periods.
