Philosophie Zoologique “Zoological Philosophy, or Exposition with Regard to the Natural History of Animals” is an book by the French naturalist Jean-Baptiste Lamarckin which he outlines his pre-Darwinian theory of evolutionpart of which is now known as Lamarckism. It is potentially a valuable resource for scholars interested in the history of evolutionary thought, showing how one nineteenth-century theorist engaged with earlier ideas in an philosiphie to promote the public phklosophie of science.

However, he made more of an impact outside France and after his death, where leading scientists such as Ernst HaeckelCharles Lyell and Darwin himself recognised him as a major zoologist, with theories that presaged Darwinian evolution.
Retrieved 31 December The History of an Idea. Together, Lamarck’s laws imply the steady adaptation of animals to their environments. The original thin paper covers, designed to be economical and temporary, had begun to disintegrate, and the sewing holding the blocks of pages together had almost completely broken down.
Lyell begins by noting that Lamarck gives no examples at all of the development of any entirely new function “the substitution of some entirely new sense, faculty, or organ” but only proves that the “dimensions and strength” of some parts can be increased or decreased.

Jo carefully lifted off the remaining spine fragments and painstakingly reassembled them on Japanese paper.
A made-to-measure box was then constructed from archival-grade materials, ensuring the volumes could be stored and accessed without incurring further damage over time. With respect to the Philosophie Zoologiqueit is no reproach to Lamarck to say that the discussion of the Species question in that work, whatever might be said for it inwas miserably below the level of the knowledge of half a century later.
The first law stated that use or disuse would cause body structures to grow or shrink over the generations. Once repaired the volumes were re-sewn, given new spine-linings, and laced into new paper wrappers.
De l’Ordre naturel des Animaux et de la disposition qu’il faut donner a leur distribution generale pour la rendre conforme a l’ordre meme de la nature Lamarckism was popularised in the English-speaking world by the speculative Vestiges of the Natural History of Creationpublished anonymously by Robert Chambers in De la Vie, de ce qui la constitue, et des Conditions essentielles a son existence dans un corps Lyell similarly criticises the way Lamarck supposed the antelope and gazelle acquired “light agile forms” able to run swiftly; or the “camelopard” giraffe became “gifted with a long flexible neck”.
Du tissu cellulaire, considere comme la gangue dans laquelle toute organisation a ete formee In the French-speaking world in his lifetime, Lamarck and his theories were rejected by the major zoologists of the day, including Cuvier. Rather he believed that simple forms of life were created continuously by spontaneous generation.
Lamarck: Philosophie zoologique
In Thomas Henry Huxleythe comparative zoologiqie known as “Darwin’s Bulldog” for his energetic advocacy of Darwinian evolution,  wrote that. Considerations sur les Causes physiques de la Vie, les conditions qu’elle exige pour exister, la force excitatrice de ses mouvemens, les facultes qu’elle donne aux corps qui la possedent, et les resultats de son existence dans les corps I do not think that any impartial judge who reads the Philosophie Zoologique now, and who afterwards takes up Lyell’s trenchant and effectual criticism published as far back aswill be disposed to phiposophie to Lamarck a much higher place in the establishment of biological evolution than that which Bacon assigns to himself in relation to physical science generally,—buccinator tantum.
Lamarck described speciation as follows: Lamarck was largely ignored by the major French zoologist Cuvierbut he attracted much more interest abroad.
Journal of the History of Biology. Lamarck’s evolutionary theory made little immediate impact on his fellow zoologists, or on the public at the time.

His second law held that any changes made in this way would be inherited. University of California Press. He argued that gaps between differing kinds of animals resulted from the extinction of intermediate forms: Those conditions together imply that species continuously change by adaptation to their environments, forming a branching series of evolutionary paths.
In that interval of time the elucidation of the structure of the lower animals and plants had given rise to wholly new conceptions of their relations; histology and embryologyin the modern sense, had been created; physiology had been llamarck the facts of distribution, geological and geographical, had been prodigiously multiplied and reduced to order.
Lyell goes on, assuming for the sake of argument that Lamarck was right about the creation of new organs, that Lamarck’s theory would mean that instead of the nature and form of an animal giving lamatck to its behaviour, its behaviour would determine .
