Evolutionary Biology at the Turn of the Twentieth Century. New Concepts of Directed Evolution in they concepts existed in the 1900s–1930s, while none of them seemed to dominate. Some of them were associated with orthogenesis, which was at the peak of popularity in the 1910s–1920s. New concepts of directed evolution were born in Russia (nomogenesis, historical biogenetics), the USA (aristogenesis),

Orthogenesis and the Modern Evolutionary Synthesisess is partly due to the energetic claims of its authors that they had solved all the main problems of the evolutionary biology. The modern Darwinism was formed over a long period of time by many scientists. This circumstance was both its weakness and its strength. On the one hand, the vagueness of

“Laws” in Biologyvolution considered that these laws indicated the existence of order in the living nature similar to the order of chemical elements or the existence of internal forces driving evolution. On the contrary, authors opposing the concepts of directed evolution argued that there was no need to invent obsc

Anticipation, Parallelisms and Convergences re-emerge either as adaptations or as a mark of a new evolutionary stage. A similar phenomenon is the emergence of aristogenes, organs useless for an organism but creating preconditions for the origin of “useful” organs in its distant descendants. Unlike “anticipatory” features, they do not disappe
