Australian researchers have claimed there are signs of life underneath the ice in southern Antarctica.
A study was carried out by scientists from the Australian National University in the region surrounding Mount Erebus, the southernmost active volcano on Earth.
The researchers believe volcanic activity might have created a network of caves under the glaciers which coat the continent.
Despite the strong winds and cold making most of the continent inhabitable, the heat generated by the volcano and light filtering down through lighter layers of ice might have provided conditions for life to exist.
This theory was supported by analysis of soil samples gathered by the team turning up traces of DNA from algae and other organisms.
The researchers even found DNA sequences which could not be identified, suggesting there might be as-yet undiscovered species.
