Vedclass · Answer

(B) The origin of life from inorganic materials (abiogenesis) occurred under the reducing conditions of the primitive atmosphere,which lacked free oxygen. In the present atmosphere,the presence of a high concentration of oxygen makes the environment oxidizing. Oxygen is highly reactive and would oxidize any simple organic molecules formed,preventing them from polymerizing into complex life-sustaining molecules. Therefore,the current oxidizing atmosphere prevents the spontaneous generation of life from inorganic matter.
