Question

Experimental evidence in favour of chemical origin of life was provided by

• A. A. I. Oparin and J. B. S. Haldane
• B. Miller and Urey
• C. Both A and B
• D. None of the above

Answer 1

Answer: (B)

Miller and Urey

The Miller–Urey experiment was a chemical experiment that simulated the conditions thought at the time to be present on the early earth and tested the chemical origin of life under those conditions. The experiment tested Alexander Oparin's and J. B. S. Haldane's hypothesis that conditions on the primitive earth favoured chemical reactions that synthesise more complex organic compounds from simpler inorganic precursors.

So, the correct answer is option B.
