|Cuvier (ky'vē-ā') Pronunciation Key
French anatomist who is considered the founder of comparative anatomy. He originated a system of zoological classification that grouped animals according to the structures of their skeletons and organs. Cuvier extended his system to fossils; his reconstructions of the way extinct animals looked, based on their skeletal remains, greatly advanced the science of paleontology.
