Oparin and Haldane

Vedclass · Answer

(B) The theory of chemical evolution,also known as the $Oparin-Haldane$ hypothesis,suggests that life originated from non-living organic molecules through a series of chemical reactions in the primitive atmosphere.$A.I. Oparin$ (a Russian scientist) and $J.B.S. Haldane$ (a British scientist) independently proposed that the first form of life could have come from pre-existing non-living organic molecules (e.g.,$RNA$,$protein$,etc.) and that the formation of life was preceded by chemical evolution,i.e.,formation of diverse organic molecules from inorganic constituents.

$Oparin$ and $Haldane$ proposed that the first form of life could have come from pre-existing non-living organic molecules.
