Why are the Miller-Urey experiments essential to the theory of evolution?
A. They showed that life can only come from life.
B. They showed that electricity can create life.
C. They showed how organic molecules could be made from Earth's early atmosphere.
D. They showed the role that natural selection played in the evolution of modern day organisms.

The Miller-Urey experiments were crucial because they demonstrated that organic molecules, the building blocks of life, could form from inorganic substances under conditions simulating the early Earth's atmosphere. This evidence supports the idea of abiogenesis, which is essential to the theory of evolution. Thus, these experiments help explain how life might have originated naturally on Earth. ;

The Miller-Urey experiments demonstrated that organic molecules could be synthesized from inorganic materials under conditions simulating early Earth. This supports the idea of abiogenesis, which is crucial for the theory of evolution as it explains how life might have originated naturally. Therefore, the correct answer is C: They showed how organic molecules could be made from Earth's early atmosphere.
