Lamarckism
Jean-Baptiste Lamarck.
Jean-Baptiste Lamarck did not use external books to explain his theory; rather, he authored several foundational works in which he systematically presented his ideas on organic transformation and the inheritance of acquired characters.1
He detailed his theory of evolution in the following publications:
- Recherches sur l’organisation des corps vivans (1802; "Research on the Organization of Living Bodies")1
- Philosophie zoologique (1809; "Zoological Philosophy"), which contains his most explicit explanations regarding the influence of environmental circumstances and the increasing complexity of organisms1
- Histoire naturelle des animaux sans vertèbres (1815–22; "Natural History of Invertebrate Animals"), specifically within the introduction to this multivolume work on invertebrate classification1
Through these texts, Lamarck argued that organisms adapt to their environments by adopting new habits, which lead to physical changes that can be inherited by subsequent generations. While his specific mechanism for evolution is now discredited by modern genetics, he remains recognized as the first naturalist to provide a comprehensive, systematic theory of organic evolution.12
