In the 1950s, Miller and Urey obtained support for the hypothesis that simple organic molecules needed to build more complex biomolecules could be synthesized from inorganic compounds under conditions thought to simulate those on early Earth. Since then, additional information has emerged that weakens this support. Which statement below describes the reason why results from the Miller-Urey experiments are no longer considered strong evidence of a prebiotic-soup origin of life? A. The Miller-Urey experiments did not include clay, which is known to have been present during Earth's early history. B. The type of energy used in the Miller-Urey experiment was unrealistic based on what is known about early Earth conditions. C. The temperature conditions used in the Miller-Urey experiment could not have been present during Earth's early history. D. Some of the gases used in the Miller-Urey experiment are now known not to have been present on early Earth.
