In the Miller-Urey experiment, a variety of inorganic gases were mixed in a chamber. The gases were chosen to mimic Earth’s early atmosphere. A spark of electricity was passed through the chamber. The gases reacted to form amino acids and other simple organic molecules.How does the Miller-Urey experiment relate to the history of life on Earth
|
|
It provides strong evidence for the mechanism by which the first living things evolved
|
|
|
It suggests a mechanism by which compounds that are essential for life were first assembled
|
|
|
It provides evidence against the hypothesis that life evolved from non-living compounds
|
|
|
It is unrelated to the history of life on Earth because living things were always present in oceans and on land

Explanation:
Detailed explanation-1: -The Miller-Urey experiment provided the first evidence that organic molecules needed for life could be formed from inorganic components. Some scientists support the RNA world hypothesis, which suggests that the first life was self-replicating RNA.
Detailed explanation-2: -The Miller-Urey experiment was a simulation of conditions on the early Earth testing the idea that life, or more specifically organic molecules, could have formed by nothing more than simple chemical reactions. Miller’s success validated the theoretical ideas of A.I.
Detailed explanation-3: -The mixture of gases used was methane, ammonia, water and hydrogen.
