Oparin-Haldane theory | Hypothesis, Origin of Life, & Miller-Urey ...
Oparin-Haldane theory, idea that organic molecules could be formed from abiogenic materials in the presence of an external energy source—e.g., ultraviolet radiation —and that Earth’s primitive atmosphere was reducing (having very low amounts of free oxygen) and contained ammonia and water vapour, among other gases.
Alexander Oparin - Wikipedia
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.

Aleksandr Oparin (born Feb. 18 [March 2, New Style], 1894, Uglich, near Moscow, Russia—died April 21, 1980) was a Russian biochemist noted for his studies on the origin of life from chemical matter. By drawing on the insights of chemistry, he extended the Darwinian theory of evolution backward in time to explain how simple organic and ...
Origins of Life: Chemical and Philosophical Approaches
2015年11月19日 · Oparin’s model consists of spontaneous formation of coacervates that encapsulate chemical matter, undergo primitive self-replication, and provide a pathway to a primitive metabolism. We review the experimental updates of his model from our laboratory and discuss types of selection that could have occurred in these primitive systems.
Oparin more than 75 years ago, about the quintessential conundrum of how life self-assembled from inanimate components. The Soviet biochemist’s answer is his book The Origin of Life (1936 ...

Preface: The origin of life and astrobiology - PMC
2020年10月17日 · The Haldane-Oparin theory on the origin of life was tested to a limited extent by two American chemists, Harold Urey and Stanley Miller. They successfully produced organic molecules from some of the inorganic components thought to have been necessary for the appearance of life, the prebiotic phase.
Alexandr I. Oparin and the Origin of Life: A Historical …
2016年11月28日 · The heterotrophic origin of life proposed by A. I. Oparin in the 1920s was part of a Darwinian framework that assumed that living organisms were the historical outcome of a gradual transformation of lifeless matter. Eighty years ago, he presented a much more detailed scheme of the processes that may have led to life.
