Le Règne Animal (The Animal Kingdom) is the most famous work of the French naturalist Georges Cuvier. It sets out to describe the natural structure of the whole of the animal kingdom based on comparative anatomy, and its natural history. Le Règne Animal was influential in being widely read, and in presenting accurate descriptions of groups of related animals, such as the living elephants and the extinct mammoths, providing convincing evidence for evolutionary change to readers including Charles Darwin, although Cuvier himself rejected the possibility of evolution.
