Answer :
The Miller-Urey experiments essential to the theory of evolution because they showed how organic molecules could be made from Earth's early atmosphere.
Answer:
The correct answer would be "They showed how organic molecules could be made from Earth's early atmosphere."
Miller-Urey experiment showed the chemical origin of life.
They reproduce the conditions similar to early earth and used chemicals like water, methane, hydrogen, and ammonia.
They induce conditions like water vapors, gaseous mixture, lighting through them, and cycling of the hot and cold atmosphere.
After some time, the presence of organic compounds such as amino acids.
Thus, it showed how organic molecules were formed from early earth's atmosphere.
