3. The 1952 Miller-Urey experiment involved heating water, methane, ammonia, and hydrogen in sealed, interconnected glass vials. The purpose of this experiment was to simulate the conditions and substances on early Earth before life. Heating these simple substances led to the formation of 23 simple amino acids in one week. Amino acids can be linked together into long, complex molecules that cells need to carry out the basic life functions. What can be determined by analyzing the data produced by the Miller-Urey experiment?
