The oparin-haldane theory in the 1920s british scientist jbs haldane and russian biochemist aleksandr oparin independently set forth similar ideas concerning the conditions required for the origin of life on earth. The oparin-haldane hypothesis the oparin-haldane hypothesis is a hypothesis independently developed by two scientists: russian chemist ai oparin and british scientist john haldane.
A definition of the term oparin-haldane hypothesis is presented it refers to an idea which asserts that life began with simple organic compounds formed from atmospheric gases, followed by more complex compounds formed in the seas through a variety of reactions.
It was haldane who gave the name soup to the theory the theory is variously known as primordial soup theory, prebiotic soup theory, and oparin-haldane hypothesis biochemist robert shapiro has summarized the theory in its mature form as follows: early earth had a chemically reducing atmosphere.
In 1924, aleksandr oparin (and john haldane separately in 1929) hypothesized that the formation of amino acids and proteins from non-living chemicals, a process known as abiogenesis, could have.

Haldane coined the term 'prebiotic soup', and this became a powerful symbol of the oparin-haldane view of the origin of life.
In 1924, oparin officially put forward his influential theory that life on earth developed through gradual chemical evolution of carbon-based molecules in a “primordial soup”, at just about the same time as the british biologist j b s haldane was independently proposing a similar theory as early as 1922, at a meeting of the russian.
