Following the initial Miller-Urey experiment, new evidence indicated that major volcanic eruptions would have released carbon dioxide, nitrogen, hydrogen sulfide, and sulfur dioxide into the atmosphere of early Earth.When these gasses were incorporated into an experiment similar to the first, the experiment produced
A) exactly the same chemicals as the first experiment.
B) fewer types of amino acids than the first experiment.
C) organic compounds not produced in the first experiment, including 20 amino acids.
D) no basic small molecules of life.
E) atmospheric oxygen.

Question

Quizplus · Accepted Answer

When the gases released by volcanic eruptions were used in a Miller-Urey type experiment, it produced organic compounds, including 20 amino acids, that were not produced in the first experiment. This suggests that the early Earth's atmosphere may have contained different gases than previously thought, and that the production of organic compounds may have been more common than initially believed.
