Concept History
In the most expanded form, Theodor Aimer presented this concept in 1888 - 1897 . Subsequently, proponents of orthogenesis as factors that determine the course of evolution, proposed the features of DNA sequences or any cellular structures.
Many prominent paleontologists have proposed their own concepts of orthogenesis. In our country [ which one? ] famous supporters of orthogenesis (in different versions) were the zoologist and geographer Berg L.S. (author of the concept of nomogenesis ), entomologist A.A. Lyubishchev , paleobotanist Meyen S.V. The orthogenetic concepts of these authors vary widely.
In a certain sense, the law of homological series of N.I. Vavilova can also be considered orthogenetic.
