Question

why are the miller - urey experiments essential to the theory of evolution? 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. they showed that life can only come from life.

Explanation:

The Miller - Urey experiments simulated Earth's early atmosphere and demonstrated the formation of organic molecules, which are crucial for the origin of life and thus important for the theory of evolution. Electricity was used to simulate lightning in the experiment, but it didn't create life. Natural selection is not related to the Miller - Urey experiments, and the idea that life can only come from life (biogenesis) is not what the Miller - Urey experiments showed.

Answer:

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