Vedclass · Answer

(D) The concept of chemical evolution,often referred to as the Oparin-Haldane hypothesis,suggests that life originated from non-living organic molecules. It proposes that the primitive Earth's atmosphere,which was reducing in nature,allowed for the synthesis of simple organic compounds from inorganic precursors through the influence of energy sources like lightning and solar radiation. These molecules eventually aggregated to form more complex structures,leading to the origin of life under suitable environmental conditions.
