Primordial soup, also known as prebiotic 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. [1] [2]
Haldane's article on abiogenesis in 1929 introduced the "primordial soup theory", which became the foundation for the concept of the chemical origin of life. He established human gene maps for haemophilia and colour blindness on the X chromosome , and codified Haldane's rule on sterility in the heterogametic sex of hybrids in species .
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 ...

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 ...
The concept of the primordial sandwich was proposed by the chemist Günter Wächtershäuser to describe the possible origins of the first cell membranes, and, therefore, the first cell. [ 1 ] According to the two main models of abiogenesis , RNA world and iron-sulfur world , prebiotic [ 2 ] processes existed before the development of the cell ...
The original replicator (Dawkins Replicator) was the initial molecule which first managed to reproduce itself and thus gained an advantage over other molecules within the primordial soup. [15] As replicating molecules became more complex, Dawkins postulates, the replicators became the genes within organisms, with each organism's body serving ...
Difficult to find the main explanation-summary of what the primordial soup is. Perhaps would be nice to have a definition of sorts in the first paragraph of the article (for example, what was it, and what molecules it actually consisted of) — Preceding unsigned comment added by 185.253.178.4 ( talk ) 14:46, 22 September 2019 (UTC) [ reply ]
