Describe Stanley Miller's landmark experiment. How did the results of this experiment change hypothesis regarding the evolution of life on Earth?
What will be an ideal response?
In 1952, Stanley Miller conducted a laboratory experiment where he exposed a mixture of carbon dioxide, methane, ammonia, hydrogen, and water (the components of the early atmosphere and ocean) to ultraviolet light (from the Sun) and an electrical spark (to imitate lightning) By the end of the first day, the mixture turned pink, and after a week it was a deep, muddy brown, indicating the formation of a large assortment of organic molecules, including amino acids—which are the basic components of life—and other biologically significant compounds. This demonstrated that organic molecules could have been produced in Earth's early oceans to become life's precursor molecules about 4 billion years ago.
