This page provides all possible meanings and translations of the word orthogenesis
A series of similar mutation in successive generation, producing evolutionary change.
Orthogenesis, orthogenetic evolution, progressive evolution or autogenesis, is the hypothesis that life has an innate tendency to evolve in a unilinear fashion due to some internal or external "driving force". The hypothesis is based on essentialism and cosmic teleology and proposes an intrinsic drive which slowly transforms species. George Gaylord Simpson in an attack on orthogenesis called this mechanism "the mysterious inner force". Classic proponents of orthogenesis have rejected the theory of natural selection as the organising mechanism in evolution, and theories of speciation for a rectilinear model of guided evolution acting on discrete species with "essences". The term orthogenesis was popularized by Theodor Eimer, though many of the ideas are much older.
