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.)

Scientists Stanley Miller and Harold Urey set up an experiment modeling the environmental conditions thought to exist during the early stages of Earth's formation.
The setup of Miller and Urey's experiment is shown below.
Which conclusion about the origin of life could be drawn from the potential results of this experiment?
Life assembled from chemical building blocks.
Life began when water vapor became electrified.
Life evolved from the DNA of simple unicellular organisms.
Life began when salt water caused a mutation in an ancient virus.
What argument convinced most scientists in the 1800s that Earth was more than 6,000 years old?
The discovery of fossils
Arguing that everyday observable geological processes (like erosion) could explain large geological features if they had occurred for millions of years, rather than large catastrophic events that happened suddenly
The discovery that radioactive isotopes could be used to determine historical dates
The discovery that Earth orbits around the sun, rather than the sun orbiting around Earth
The formation of the first living organism is still a mystery. Outline and explain the steps in the origin of life. Explain where the original organisms must have lived and why?

- 'The origin of life is a co‐evolutionary process.' Briefly explain.arrow_forwardOne 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_forwardDirect evidence of life on early Earth comes from fossils of microorganisms that lived 3.5 billion years ago.
