Miller/Urey Experiment Mimicking early Earth Hot oceans - flask with boiling water connected to… Earth’s early atmosphere - flask with gases. Lightning - energy from sparks. Condensation of products from gas flask (rain) fed back into the “ocean” flask.

Miller/Urey Experiment After weeks, the “ocean” contained complex molecules including amino acids. “Ocean” with complex molecules was called “prebiotic soup” by Oparin. Many scientists have confirmed these results.
