Tychogenesis

(also tychism), a hypothesis according to which the evolution of organisms is based on chance variations. The term “tychogenesis” was introduced by the American paleontologist H. Osborn in 1929. Darwin’s theory of evolution may be considered a variant form of tychogenesis, since according to Darwinism the chief driving force of evolution—natural selection—has to do with the hereditary changes in organisms that occur by chance in relation to the influences of the external environment.
