Professeur d'histoire naturelle des insectes, vers et animaux microscopiques, Jean-Baptiste Lamarck (1744-1829) passa plusieurs années à établir une classification raisonnée des invertébrés. Travaillant sur de multiples domaines (météorologie, physique, hydrologie), il invente le terme de «biologie».
Précurseur des théories de l'évolution et opposé aux thèses fixistes de son époque, il élabore au début du XIXe siècle la théorie du transformisme basée sur l'hérédité des caractères acquis.
Monument to Jean-Baptiste Lamarck
Professor of natural history specializing in insects, worms, and microscopic animals, Jean-Baptiste Lamarck (1744-1829) spent several years establishing a systematic classification of invertebrates. Working across multiple fields (meteorology, physics, hydrology), he coined the term "biology."
A precursor of evolutionary theories and opposed to the fixist theses of his time, he developed at the beginning of the 19th century the theory of transformism based on the heredity of acquired characteristics.

1. Jean-Baptiste Lamarck (Wikipedia). Excerpt:
Jean-Baptiste Pierre Antoine de Monet, chevalier de Lamarck (1 August 1744 – 18 December 1829), often known simply as Lamarck, was a French naturalist, biologist, academic, and soldier. He was an early proponent of the idea that biological evolution occurred and proceeded in accordance with natural laws,[3] though the mechanism he suggested has been refuted at large.(Submitted on February 2, 2026.)
The modern era generally remembers Lamarck for a theory of inheritance of acquired characteristics, called Lamarckism (accurately named after him), soft inheritance, or use/disuse theory, which he described in his 1809 Philosophie zoologique. Though, the idea of soft inheritance antedates him, and while it was a small element of his theory of evolution, in his time it was accepted by many natural historians. Lamarck's idea of use/disuse later aligned with Darwin's idea of natural selection and is believe to in part have inspired Darwin, who ended up contradicting Lamarckism. Lamarck's contribution to evolutionary theory consisted of the first truly cohesive theory of biological evolution, in which an alchemical complexifying force drove organisms up a ladder of complexity, and a second environmental force adapted them to local environments through use and disuse of characteristics, differentiating them from other organisms. Scientists have debated whether advances in the field of transgenerational epigenetics mean that Lamarck was to an extent correct, or not.
