The Miller-Urey experiment determined which of the following results?
Correct answer: D. Organic molecules can arise from inorganic precursors
- A. DNA replicates by semiconservative replication
- B. Cyanobacteria were responsible for semiconservative replication
- C. The early atmosphere was composed of ammonia and methane
- D. Organic molecules can arise from inorganic precursors
Explanation
Miller-Urey experiment demonstrated that organic molecules can arise from inorganic precursors under conditions similar to those believed to exist in the early Earth's atmosphere. This result provided significant insights into the possibility of chemical evolution and the origin of life on Earth.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
