Volcanoes and lightning may have provided the vital spark that kick started life on Earth, a new study has suggested. To come to the conclusion, researches, led by the University of California at San Diego, used modern techniques to re-analyze results from a 1950s experiment - they studied "primordial soup" gas samples created by US prof Stanley Miller in 1958. The researches discovered a multitude of amino acids, the basic building blocks of life, which can be assembled together to form proteins. In 1953, Miller conducted the famous experiment in which he attempted to recreate the atmospheric conditions present just before life appeared on Earth four billion years ago.
