Until (0) RELATIVELY (RELATIVE) recently, it was thought that extreme heat and cold presented 1MOUNT problems to living organisms and that all life existed in a narrow range of 2FAVOUR temperatures. However, the discovery of extremophiles has forced a 3ASSESS of that view. Extremophiles are bacteria that survive, and even thrive, in 4SEEM impossible conditions. 5PROBABLE as it may seem, some exist at temperatures exceeding 80°C in geysers and hot springs, while others live in the freezing conditions of the Antarctic 6WILD. While most species of larger animals are 7THREAT by global warming, even to the point of 8EXTINCT, that kind of ecological change may actually benefit the extremophiles. These mysterious organisms may survive long after the human race.
