Jean-Baptiste Lamarck (Aug. 1, 1744 - Dec. 18, 1829) - pioneer of evolutionism

Summary/Abstract: J. B. Lamarck was “the first evolution theorist” affirms Stephen Jay Gould (1941–2002, palaeontologist and biologist). The great scientist is known through his theory regarding the inheritance of the acquired characters (soft inheritance) and the use and disuse model through which the organisms have developed their characteristics. The biologist offered answers to three essential problems of modern biology: the origin of life (living matter appeared from the unliving one, without Lamarckţs showing of the way the process took place), animal adaptation (he is the first naturalist that offers a scientific explanation, respective, physiological process pure metabolic, for plants and of a nervous nature, in animals which was under the influence of the environmental factors) and the origin of man (the few studies that were made until that date didnţt allow him to develop this domain). J. B. Lamarck died at 85 years, leaving to posterity a large opera and a new, unitary idea, that arranges the biological facts and explains the origin of all species of plants, animals, including of man, from other speciei, the evolution theory.
