Devised to test Alexander Oparin's 1924 hypothesis, experiments similar to this one were performed by Wilde and MacNevin. A purely aqueous variation used hydrogen cyanide to produce adenine, and was performed by Joan Oró. A 2008 reanalysis of the solutions in this experiment found that the "volcanic" version of the experiment produced far more compounds than previously realized—not five, but twenty-two amino acids.

Using an electrical spark to simulate lightning and producing organic compounds from hydrogen, ammonia, water, and methane, name this 1952 experiment which demonstrated the feasibility of abiogenesis on an early Earth.
