An experiment conducted by Stanley-Miller simulated meteorite conditions and were able to produce important monomers.
|
|
|
Pieces of meteorites that have been found to contain a variety of organic chemicals.
|
|
|
The astronomer Edward Hubble observed this happening on other planets.
|
|
|
Meteorites are amphiphilic and therefore are capable of carrying foreign molecules through Earth’s atmosphere.

Detailed explanation-1: -Some scientists believe that the first monomers on early Earth came from meteorites that fell to Earth. What evidence do scientists use to support this theory? An experiment conducted by Stanley-Miller simulated meteorite conditions and were able to produce important monomers.
Detailed explanation-2: -The most accepted theory for the origin of life is Oparin-the Haldane theory. Reason for acceptance of this theory: This theory states that from the abiogenetic material organic molecules could be formed in the presence of an external energy source.
Detailed explanation-3: -The study of meteorites has helped us understand the beginnings of our solar system, how planets and asteroids formed and how impacts of large meteorites have altered Earth’s history and life on our planet.
Detailed explanation-4: -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.
Detailed explanation-5: -Haldane, unfamiliar with Oparin’s theory, believed that simple organic molecules formed first and in the presence of ultraviolet light became increasingly complex, ultimately forming cells. Haldane and Oparin’s ideas formed the foundation for much of the research on the origin of life, specifically formation of cells.
