![[miller1.jpg]] An chemistry experiment conducted in 1952 where a solution of water, methane, ammonia and hydrogen – resembling the earth's 'primordial soup' - was continuosly shocked by electric sparks. After a day, the reaction was stopped and five amino acids were found. > "Vials preserved from the original experiments were able to show that there were actually well over 20 different amino acids produced in Miller's original experiments." > "Just turning on the spark in a basic pre-biotic experiment will yield 11 out of 20 amino acids."
