Textbook Question
Chapter 15, Problem 18TYK
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.)

Students have asked these similar questions
give a description of the theory proposed by oparin, miller, sagan, fox and others for the orgin of life from non-living material. What do you think about the origin of life?
-philosophy of science
For a long time, it was believed that life originated from decaying matter. What is this theory known as? Name the scientist who experimentally disproved this theory.
Which of the following is least reasonable regarding the Urey-Miller experiment?
Group of answer choices
The experiment was an important breakthrough in the study of the origin of life.
The experiment conifirmed that several of the key molecules of life could have been synthesised naturally on the primitive Earth.
The amino acids and other molecules produced in the experiment, and possibly present in the early atmosphere, could have participated in 'prebiotic' chemical processes, ultimately creating life.
This experiment, and others which followed, suggests that simple biologically significant molecules can evolve naturally under sets of conditions that may have existed not only on early Earth, but potentially elsewhere in the solar system and beyond.
The experiment was the first demonstration of abiogenesis (life from non-life).

- One of the simplest definitions of a life-form is anything with the capacity to reproduce and regulate itself. Before life began, the complex organic, or hydrocarbon-bearing, molecules that makeup RNA and DNA, the building blocks of life, must have formed. No one knows exactly how life is formed from these molecules, but many ideas have been put forward. As you enter this area, go toward the large video screen on the right and explore the “Life at the hydrothermal Vents” label deck. Some scientists theorize that life begins at deep-sea vents. Find three lines of evidence to support this claim.arrow_forwardWhich of the following statements cannot be tested by science today?
