Primordial soup, also known as prebiotic soup and Haldane soup, is the hypothetical set of conditions present on the Earth around 3.7 to 4.0 billion years ago. It is an aspect of the heterotrophic theory (also known as the Oparin–Haldane hypothesis) concerning the origin of life, first proposed by Alexander Oparin in 1924, and J. B. S. Haldane in 1929.
Since then, the primordial soup theory (Oparin–Haldane hypothesis) has become the foundation in the study of abiogenesis. [88] [89] [90] Although Oparin's theory became widely known only after the English version in 1936, Haldane accepted Oparin's originality and said, "I have very little doubt that Professor Oparin has the priority over me ...
The 2015 NASA strategy on the origin of life aimed to solve the puzzle by identifying interactions, intermediary structures and functions, energy sources, and environmental factors that contributed to the diversity, selection, and replication of evolvable macromolecular systems, [2] and mapping the chemical landscape of potential primordial ...

Oparin and Haldane suggested that the atmosphere of the early Earth may have been chemically reducing in nature, composed primarily of methane (CH 4), ammonia (NH 3), water (H 2 O), hydrogen sulfide (H 2 S), carbon dioxide (CO 2) or carbon monoxide (CO), and phosphate (PO 4 3−), with molecular oxygen (O 2) and ozone (O 3) either rare or absent.
Christine Leunens (born 29 December 1964) is a New Zealand-Belgian novelist. She is the author of Primordial Soup, A Can of Sunshine, and In Amber's Wake, which have been translated into twenty-five languages. [1]
Sidney Walter Fox (24 March 1912 – 10 August 1998) was a Los Angeles-born biochemist responsible for discoveries on the origins of biological systems. Fox explored the synthesis of amino acids from inorganic molecules, the synthesis of proteinous amino acids and amino acid polymers called "proteinoids" from inorganic molecules and thermal energy, and created what he thought was the world's ...
Alexander Ivanovich Oparin (Russian: Александр Иванович Опарин; 2 March [O.S. 18 February] 1894 – 21 April 1980) was a Soviet biochemist notable for his theories about the origin of life and for his book The Origin of Life. He also studied the biochemistry of material processing by plants and enzyme reactions in plant ...
