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 ...
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.
Life of Pi is a Canadian philosophical novel by Yann Martel published in 2001.

Warm little pond. A warm little pond is a hypothetical terrestrial shallow water environment on early Earth under which the origin of life could have occurred. The term was originally coined by Charles Darwin in an 1871 letter to his friend Joseph Dalton Hooker. [1][2] This idea is related to later work such as the Oparin-Haldane hypothesis and ...
Coacervate (/ koʊəˈsɜːrvət / or / koʊˈæsərveɪt /) is an aqueous phase rich in macromolecules such as synthetic polymers, proteins or nucleic acids. It forms through liquid-liquid phase separation (LLPS), leading to a dense phase in thermodynamic equilibrium with a dilute phase. The dispersed droplets of dense phase are also called ...
Since then, the primordial soup theory (Oparin–Haldane hypothesis) has become the foundation in the study of abiogenesis. [86] [87] [88] 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 Miller–Urey experiment was a synthesis of small organic molecules in a mixture of simple gases in a thermal gradient created by heating (right) and cooling (left) the mixture at the same time, with electrical discharges. The Miller–Urey experiment[ 1 ] (or Miller experiment[ 2 ]) was an experiment in chemical synthesis carried out in ...
Antonie van Leeuwenhoek. Traditional religion attributed the origin of life to deities who created the natural world. Spontaneous generation, the first naturalistic theory of abiogenesis, goes back to Aristotle and ancient Greek philosophy, and continued to have support in Western scholarship until the 19th century.
