Question

What did the Miller-Urey experiment prove?

• A. That life arose on the Earth through abiogenesis.
• B. That life could have arisen on the Earth through biogenesis.
• C. That life on the Earth did not arise through abiogenesis.
• D. It proved none of the above.

Answer 1

The correct option is A That life arose on the Earth through abiogenesis.

In the 1950's, biochemists Stanley Miller and Harold Urey conducted an experiment which demonstrated that several organic compounds could be formed spontaneously (through abiogenesis) by simulating the conditions of Earth's early atmosphere.
