Question

An experimental proof to chemical origin of life was provided by

• A. Pasteur
• B. Oparin
• C. Miller
• D. Haldane

Answer 1

The correct option is C Miller

1) Chemical evolution of life stated that life originated from simple chemicals like carbon, hydrogen, nitrogen and oxygen. Chemical evolution of life was demonstrated by Miller in an experimental setup.

2) Miller circulated water methane, ammonia, and hydrogen in an airtight container and heated to vaporize them.

3) The vapour of mixture is induced by an electric discharge with the help of electrode at 800${}^o$C.

4) The mixtures were allowed to pass through a condenser.

5) The obtained liquid consisted of simple organic matter which further polymerizes to form complex organic molecule which can further generate life.

So, the correct answer is option C.
