Currently, the “Lamarckian dimension” and “Lamarckian mechanisms” are vividly discussed, indicating that they are compatible with Darwinism. However, they require an extension of Modern Synthesis to Extended Evolutionary Synthesis. Both the terms, unfortunately connected to Lamarck, really indicate a group of phenomena which can be symbolized by Jablonka’s wording: “some evolutionary changes are non-random in origin, or even result from instruction.” The Lamarckian mechanisms leading to these evolutionary changes arose, however, in the Darwinian way much earlier. This earlier stage is said too rarely, and the typical understanding of Lamarckism strongly suggests its lack. The term “Lamarckism” was and is understood very differently both at different times and in different national and ideological traditions but usually fraught with a simplified understanding of Lamarck. Most of the controversies in these issues arise from the insufficient precision of the utterance, and this from undervaluation of definition, specification of assumptions and abstract reasoning.
