What did Haldane propose about the primordial sea?
Haldane proposed that the primordial sea served as a vast chemical laboratory powered by solar energy. The atmosphere was oxygen free, and the combination of carbon dioxide, ammonia and ultraviolet radiation gave rise to a host of organic compounds. The sea became a 'hot dilute soup' containing large populations of organic monomers and polymers.

How is the Oparin theory related to the origin of life?
It was conceived as a confirmation of the Oparin and Haldane hypothesis in which many of the key molecules of life could have been synthesized in primitive earth under the kind of conditions presented by Oparin and Haldane. These molecules would then have been able to take a key role in chemical prebiotic processes, leading to the origin of life.
What is the Oparin and Haldane theory?
Biochemical origin of life or Oparin and Haldane theory. The concept of a biochemical origin of life was first proposed by Russian biochemist A.I. Thus, this theory is also called Oparin and Haldane theory. They believed the origin of life started along the origin and evolution of earth and atmosphere.
