Haldane–Oparin hypothesis of the origin of life

E194840

abiogenesis hypothesis origin of life hypothesis scientific hypothesis

The Haldane–Oparin hypothesis of the origin of life proposes that life first arose through a gradual chemical evolution of organic molecules in Earth’s early “primordial soup,” eventually leading to self-replicating systems.

How this entity was disambiguated

This entity first appeared as the object of triple T1726059 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07

Target entity: Haldane–Oparin hypothesis of the origin of life
Context triple: [J. B. S. Haldane, theoryProposed, Haldane–Oparin hypothesis of the origin of life]

A. Origins of Life (book)
"Origins of Life" is a scientific book by physicist and mathematician Freeman Dyson that explores theoretical scenarios for how life might have first emerged from nonliving matter.
B. Symbiosis in Cell Evolution
Symbiosis in Cell Evolution is a landmark scientific book by Lynn Margulis that argues complex eukaryotic cells arose through symbiotic mergers of simpler organisms, helping establish the endosymbiotic theory in evolutionary biology.
C. Microcosmos: Four Billion Years of Microbial Evolution
Microcosmos: Four Billion Years of Microbial Evolution is a popular science book by Lynn Margulis that explores the central role of microbes in the evolution and functioning of life on Earth.
D. Evolution: The Modern Synthesis
Evolution: The Modern Synthesis is Julian Huxley’s influential 1942 book that helped popularize and articulate the unified, gene-centered framework of modern evolutionary theory.
E. Gaia hypothesis
The Gaia hypothesis is a scientific theory proposing that Earth’s living organisms and their inorganic surroundings interact to form a self-regulating, complex system that helps maintain conditions suitable for life.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
