Jean-Baptiste Lamarck, pioneering French biologist who is best known for his idea that acquired characters are inheritable, an idea known as Lamarckism, which is refuted by modern genetics and evolutionary theory.
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 ...
Though he was building on the work of his mentor, Count George-Louis Leclerc de Buffon, Jean-Baptiste Lamarck (1744-1829) is often credited with making the first large advance toward modern evolutionary theory because he was the first to propose a mechanism by which the gradual change of species might take place.
The idea is named after the French zoologist Jean-Baptiste Lamarck (1744–1829), who incorporated the classical era theory of soft inheritance into his theory of evolution as a supplement to his concept of orthogenesis, a drive towards complexity.
Lamarck (1744 - 1829) remains the best known figure of the pre-Darwinian era of evolutionism. Regrettably, he is usually viewed as a mere caricature of his ideas, namely as the person who got it "wrong" for insisting on the inheritance of acquired features as the central mechanism of transmutation.
