This sort of evolution, for which Lamarck is most famous today, was only one of two mechanisms he proposed. As organisms adapted to their surroundings, nature also drove them inexorably upward from simple forms to increasingly complex ones.
The doctrine, proposed by the French naturalist Jean-Baptiste Lamarck in 1809, influenced evolutionary thought through most of the 19th century. Lamarckism was discredited by most geneticists after the 1930s, but certain of its ideas continued to be held in the Soviet Union into the mid-20th century.

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.
The French naturalist Jean-Baptiste de Monet de Lamarck (1744–1829) suggested an evolutionary theory in 1802, which was later called transformism. In this theory, he claimed that species changed and produced series. Transformations appeared when the environment and the habits acted on organisms for a long time.
