地球生命如何在严酷的远古冰川时期生存下来一直是个谜。英国和澳大利亚研究人员近日报告说,他们在澳大利亚找到了当时有大片地区未封冻的证据,说明当地曾是冰川时期的“生命绿洲”。 How Earth’s life survived the harsh ancient glaciers has been a mystery. British and Australian researchers recently reported that they found evidence of a large area not frozen at the time in Australia, indicating that the area was once a “life oasis” during the glacier.
