The Primordial Soup Theory

 

The origin of life is a scientific problem which is not yet solved until these days. A lot of theories were presented to know where life really began. In general terms, it is suggested that all life today started by common descent from a single primitive life form. One of the most known theories of the origin of life is the Primordial Soup Theory.

The idea came came from Russian scientist Alexander Oparin and English geneticist John Haldane. Oparin and Haldane thought that with the mix of gases in the atmosphere and the energy from lightning strikes, amino acids could spontaneously form in the oceans.

The Primordial Soup Theory suggest that 3 billion years ago, life began in a ocean as a result of the combination of chemicals from the atmosphere and from the space and resulted into the formation of amino acids, the building blocks of proteins, which would then evolve into the first species on Earth., the bacteria, named Cyanobacteria.
