Scientists hope that a remote lake on a dormant Chilean volcano can provide clues to what life may have been like in a far more distant place—the planet Mars.A 10-member team placed special plates in the lake on Licancabur volcano, at an altitude of 20,000 feet，on Sunday to measure the effects of ultraviolet light on organisms living there.The scientists, mostly from the United States, think learning how Licancabur organisms protect themselves may help researchers understand how life survived on early Earth and perhaps on early Mars as well.The damaging effects of UV radiation intensify at altitude and the air is very thin. And the lake is covered with ice most of the year, as would have been bodies of water on Mars.“If there was life on Mars 3.5 billion years ago, it could have used defense mechanisms similar to those used by the organisms at Licancabur volcano to survive,” said team leader Nathalie Cabrol.
