Jean-Baptiste Pierre Antoine de Monet, chevalier de Lamarck (1 August 1744 – 18 December 1829), often known simply as Lamarck (/ l ə ˈ m ɑːr k /; [1] French: [ʒɑ̃batist lamaʁk] [2]), was a French naturalist, biologist, academic, and soldier.
Lamarck by Charles Thévenin (c. 1802). Jean-Baptiste Lamarck (1744–1829) was a member of the French Academy of Sciences and a professor of botany at the Jardin des Plantes and then became the first professor of zoology at the new Muséum national d'Histoire naturelle.
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. Introductory textbooks contrast Lamarckism with Charles Darwin's theory of evolution by natural ...
The French Transformisme was a term used by Jean Baptiste Lamarck in 1809 for his theory, and other 18th and 19th century proponents of pre-Darwinian evolutionary ideas included Denis Diderot, Étienne Geoffroy Saint-Hilaire, Erasmus Darwin, Robert Grant, and Robert Chambers, the anonymous author of the book Vestiges of the Natural History of ...
In the early 19th century prior to Darwinism, Jean-Baptiste Lamarck (1744–1829) proposed his theory of the transmutation of species, the first fully formed theory of evolution. In 1858 Charles Darwin and Alfred Russel Wallace published a new evolutionary theory, explained in detail in Darwin's On the Origin of Species (1859). Darwin's theory ...
Jean-Baptiste Lamarck. Jean-Baptiste Lamarck had originally proposed a theory on the transmutation of species that was largely based on a progressive drive toward greater complexity. Lamarck also believed, as did many others in the 19th century, that characteristics acquired during the course of an organism's life could be inherited by the next ...
Lamarckism, the first cohesive theory of evolution [88] as well as a theory of inheritance of acquired characteristics, laid out by French biologist Jean-Baptiste Lamarck in 1809. Long dismissed in favour of Darwinism , recent developments in the field of epigenetics have led scientists to debate whether Lamarckism was, in fact, correct to an ...
Jean-Baptiste Lamarck's 1809 evolutionary theory, transmutation of species, was based on a progressive (orthogenetic) drive toward greater complexity. Lamarck also shared the belief, common at the time, that characteristics acquired during an organism's life could be inherited by the next generation, producing adaptation to the environment ...
