Verified step by step guidance1
Understand the context of the Miller-Urey experiment: It was conducted in 1953 by Stanley Miller and Harold Urey to investigate the chemical origins of life on Earth.
Identify the main goal of the experiment: The experiment aimed to simulate the conditions thought to be present on early Earth and test the chemical processes that could have led to the formation of organic molecules.
Recognize the setup of the experiment: The experiment used a closed system containing water, methane, ammonia, and hydrogen gases, which were believed to represent the early Earth's atmosphere.
Describe the process: The mixture was subjected to continuous electrical sparks to simulate lightning, which was thought to be a common energy source on early Earth.
Conclude with the results: The experiment successfully produced several organic compounds, including amino acids, demonstrating that simple organic molecules could form under prebiotic conditions.
