SCIENTIFIC THINKING When Stanley Miller’s experiment was published in 1953, his results made global headlines. The general public thought Miller had answered the question of how life on Earth began by creating life in a test tube. However, scientists understood that Miller’s experiment was neither a final answer nor a recipe for life. Rather, it was the first test of a long-standing hypothesis about the origin of life. Using the information in Module 15.2 (and additional research, if you wish) as an example, write an essay describing how the process of science progresses over time toward understanding how nature works. (You will find Module 1.7 helpful.)
