1937 A. Huxley Ends & Means xiv. 261 Neither Lamarckism nor the orthogenetics theory seems to be compatible with the fact that most mutations are demonstrably deleterious.
1966 Current Anthropol. 7 210/3 While I do not subscribe to the various facets of Lamarckism, orthogenetics, and typology, I do not deny that these have been used in an evolutionary context.
1983 Botany 8 336/1 Modern orthogenetics has mostly been confined to orchidology, probably because of the numerous striking parallelisms found in the subgroups of that family.
