Explain the theory of chemical evolution.

Explanation

The theory of chemical evolution states that the primitive organisms is the primordial environment of earth evolved spontaneously from inorganic substances and physical forces like lightening, UV radination volcanic activities etc. This leads to the formation of organic compounds from methane , ammonia, hydrogen and water .
According to Oparin (1924) these organic compounds could have undergone a series of reactions, leading to the formation of more complex . These complex molecules formed colloidal aggregates or coacervates, which are able to absorb and assimilate organic compounds from the aquatic environment, leanding to the origin of life .
According to Haldane, the primordial sea served as a vast chemical laboratory powered by solar energy. The UV radiation gave rise to organic compounds from `CO_(2) and NH_(3)` . Organic monomers and polymers were produced in the sea. These monomers and polymers acquired lipid mimbranes and transformed into the first living cells. This is terned as prebiotic soup by Haldane and this leads to origin of life as Oparin-Haldane view.
