Supporting this claim, in about 1855, Darwin noted that the struggle for existence would produce diversification – leading to Darwin's principle of divergence. [2] Finally, Darwin stresses the fact that the struggle for existence is a metaphor for the larger natural workings rather than the literal struggle between two individual organisms. [44]
In late September 1838, he started reading Thomas Malthus's An Essay on the Principle of Population with its statistical argument that human populations, if unrestrained, breed beyond their means and struggle to survive. Darwin related this to the struggle for existence among wildlife and botanist de Candolle's "warring of the species" in ...
Darwin was well-prepared to compare this to Augustin de Candolle's "warring of the species" of plants and the struggle for existence among wildlife, explaining how numbers of a species kept roughly stable. As species always breed beyond available resources, favourable variations would make organisms better at surviving and passing the ...
Charles Darwin's On the Origin of Species was published in 1859, arguing from circumstantial evidence that selection by human breeders could produce change, and that since there was clearly a struggle for existence, that natural selection must be taking place.
Pelevinsky Darwin, as one would expect from a natural-scientific legend, senses a non-human beginning in the beast. In Darwin's Origin of Species, a classic work, the origin of species through natural selection, or the preservation of favored breeds in the struggle for life, is represented as the consequence of a "scientific" experiment.

It is remarkable how Darwin rediscovers, among the beasts and plants, the society of England with its division of labour, competition, opening up of new markets, 'inventions' and Malthusian 'struggle for existence'. It is Hobbes' bellum omnium contra omnes. [22]
No Struggle for Existence, No Natural Selection: A Critical Examination of the Fundamental Principles of the Darwinian Theory is a 1908 book by George Paulin. Paulin argues in the book that there is no struggle for existence in nature and that all small individual variations are eventually eliminated by cross-breeding .
The Variation of Animals and Plants Under Domestication is a book by Charles Darwin that was first published in January 1868.. A large proportion of the book contains detailed information on the domestication of animals and plants but it also contains in Chapter XXVII a description of Darwin's theory of heredity which he called pangenesis.
