Question

why are the miller-urey experiments essential to the theory of evolution?
○ they showed that life can only come from life.
○ they showed that electricity can create life.
○ they showed how organic molecules could be made from earths early atmosphere.
○ they showed the role that natural selection played in the evolution of modern day organisms.

Explanation:

The Miller-Urey experiment simulated Earth's early atmosphere and conditions, successfully producing organic molecules (like amino acids) from inorganic precursors. This supported the idea that the building blocks of life could form spontaneously under ancient Earth conditions, which is a foundational step for the theory of evolution (as life's origin is tied to evolutionary processes). The other options are incorrect: the first is the principle of biogenesis, the experiment did not create life itself, and it did not focus on natural selection.

Answer:

They showed how organic molecules could be made from Earth's early atmosphere.
