Chapter 4.1, Problem 2TYK
Summary Introduction
Introduction:
Miller and Urey’s experiment was performed to understand how the origin of life took place in the primitive Earth. The experiment included an enclosed flask to represent the isolated environment of Earth. They included gases like methane, hydrogen, ammonia and water vapor that could have been present at the time of origin.

Which of the following is an appropriate null hypothesis that could be used when investigating the claim? * The level of atmospheric oxygen on modern Earth is significantly higher than on primitive Earth. Organic molecules were transported to primitive Earth by a meteorite or other celestial event.
