Explanation:

One of the widely accepted theory of evolution of life is the  theory of Chemical evolution.According to this theory, the conditions of prebiotic earth were favourable to a sort of continuing chemical evolution. that gave rise to a special class of organic molecule.Organic molecules must have evolved before the origin of life from primordial atmosphere which was anoxic and chemically reducing.Subsequent to the abiotic synthesis of organic matter, seas were converted into a hot dilute pebiotic soup.This theory was devised by John Haldane and Alexander Oparin.They proposed that on addition of energy to the gases of primitive atmosphere building blocks of life will be created.
