Solution
The correct option is B Oparin and Haldane
- Aleksandr Oparin (in 1924) and J.B.S. Haldane (in 1929) independently suggested that that life must have developed from the simple inorganic molecules which were present on earth soon after it was formed.
- Oparin proposed that early atmosphere on earth was of reducing type (not oxygen-rich) and in presence of an energy source, like lightning, the organic compounds could have undergone a series of reactions leading to more and more complex molecules.
- He proposed that the molecules formed colloid aggregates, or 'coacervates', in an aqueous environment.
- Haldane's ideas about the origin of life were very similar to Oparin's.
- Haldane proposed that the primordial sea served as a vast chemical laboratory powered by solar energy.
- Haldane coined the term 'prebiotic soup', and this became a powerful symbol of the Oparin-Haldane view of the origin of life.
