Definition of orthogenesis in English:

orthogenesis

noun ˌɔːθə(ʊ)ˈdʒɛnɪsɪsˌɔrθoʊˈdʒɛnəsəs

mass nounBiology historical

Evolution in which variations follow a particular direction and are not merely sporadic and fortuitous.
〔生〕〈主史〉直向进化，定向进化
Example sentencesExamples
- Weidenreich tried to explain the seeming contradiction between isolated regional development and the unity of the human species by advancing the notion of orthogenesis, or directed evolution.
- A once-popular hypothesized evolutionary mechanism was orthogenesis, in which change in organisms was due not to natural selection, but to internal directional trends within a lineage.
- Mutation bias is not enough to produce orthogenesis, however.
- The data is inconsistent with orthogenesis, and somehow thinks that because he can draw a line from an extant animal to its many-times-great grandparents, he has supported directed evolution.
- In contrast, other scientists imagine channeling, aka orthogenesis, to exist not only for individuals but also for species and for evolution: while there are lots of possibilities, the domain is restricted.

His major work focused on his orthogenetic developmental theory.
Example sentencesExamples

- The fuel in his orthogenetic engine is ‘mutation bias’. Mutation produces novel phenotypes, but it does not produce all novel phenotypes in equal frequency in a given population.
- Most American biologists had a looser expectation - that some progressive, or ‘orthogenetic’, force guided life in certain directions, most notably toward humanity and Anglo-American civilization.
- Evolutionary discussions after the publication of the six editions of the Origin and the later works took many shapes, and raised several different lines of inquiry including neo-Lamarckianism and orthogenetic theory.
