![]() ![]() Lamarck seems to have been chiefly led to his conclusion on the gradual change of species, by the difficulty of distinguishing species and varieties, by the almost perfect gradation of forms in certain groups, and by the analogy of domestic productions. He first did the eminent service of arousing attention to the probability of all change in the organic, as well as in the inorganic world, being the result of law, and not of miraculous interposition. des Animaux sans Vertébres.’ In these works he upholds the doctrine that all species, including man, are descended from other species. ![]() This justly-celebrated naturalist first published his views in 1801 he much enlarged them in 1809 in his ‘Philosophie Zoologique,’ and subsequently, in 1815, in the Introduction to his ‘Hist. Lamarck was the first man whose conclusions on the subject excited much attention.

Passing over allusions to the subject in the classical writers, * the first author who in modern times has treated it in a scientific spirit was Buffon. Some few naturalists, on the other hand, have believed that species undergo modification, and that the existing forms of life are the descendants by true generation of pre-existing forms.

After ornithologist and artist John Gould had confirmed its distinctness (and named it for its discoverer), the Patagonian rhea appeared among Darwin's notebook speculations as one of his first test-cases in his attempts to explain species differentiation. Birds, Plate 47." A new species of bird "Rhea Darwinii."
