. He believed that species change over time and may go extinct from geological cataclysms or become "metamorphosed" into new species. In his book ''Histoire naturelle des poissons'', he wrote:
"The species can undergo such a large number of modifications in its forms and qualities, that without losing its vital capacity, it may be, by its latest conformation and properties, farther removed from its original state than from a different species: it is in that case metamorphosed into a new species."
