Solution
Origin of life from inanimate matter was first proposed by Alexander Oparin & J.B.S Haldane. According to them, the inorganic molecules present in the primitive atmosphere combined to form simple organic compounds such as sugars, fatty acids, glycerol, amino acids, nitrogen bases etc. These organic molecules are the basis components of life which further combined to give first life.
This Oparin -Haldane hypothesis was proved by Urey- Miller in 1953. They conducted an experiment in which they created an atmosphere containing CH4 , H2, H2O, and NH3 in a reaction vessel. Next, they ran a continuous electric current through the system, to simulate lightning, resulting in the production of several small organic molecules including urea, hydrogen cyanide, acetic acid and amino acids. These amino acids are the building blocks of proteins in living cells. Hence this shows that life originated from inanimate matter.
