Detailed explanation-1: -The Oparin-Haldane hypothesis suggests that life arose gradually from inorganic molecules, with “building blocks” like amino acids forming first and then combining to make complex polymers.

Detailed explanation-2: -Oparin believed that the life developed from microscopic spontaneously formed spherical lipid molecules held together by electrostatic forces, probably the earliest form of cells. These molecules most likely functioned as enzymes, essential for the biochemical metabolic reactions necessary for life’s evolution.

Detailed explanation-3: -He created electric discharge in a closed flask containing methane, hydrogen, ammonia and water vapour at 8000C. This resulted is the formation of amino acids. Hence, this experiment supported that the chemical evolution of organic molecules occurred from the inorganic substances.

Detailed explanation-4: -Oparin and Haldane believed in the chemical evolution of life. They proposed that the First form of life could have come from pre-existing non-organic molecules, S.L. Miller created electric discharge in a closed flask containing CH4, H2, NH3.
