why are the miller-urey experiments essential to the theory of evolution?\n○ they showed that life can only come from life.\n○ they showed that electricity can create life.\n○ they showed how organic molecules could be made from earths early atmosphere.\n○ they showed the role that natural selection played in the evolution of modern day organisms.
Answer
Brief Explanations:
- The Miller - Urey experiment simulated Earth's early atmosphere (with gases like methane, ammonia, hydrogen, and water vapor) and used electrical sparks (to simulate lightning). The result was the formation of organic molecules (like amino acids), which are the building blocks of life.
- Option 1: The idea that life can only come from life is related to biogenesis, not the Miller - Urey experiment.
- Option 2: The experiment did not create life, just organic molecules, so this is incorrect.
- Option 4: Natural selection was proposed by Darwin and is about the survival of the fittest in populations, not what the Miller - Urey experiment demonstrated.
Answer:
C. They showed how organic molecules could be made from Earth's early atmosphere.
