Knowra Georges Cuvier Georges Cuvier Georges Cuvier was a French naturalist whose comparative anatomy helped establish vertebrate paleontology. He argued that successive catastrophes explained fossil faunas and extinctions.
Comparative anatomy : The study of anatomical similarities and differences among organisms, used to infer function, relationship, and evolutionary history. Cuvier used anatomical correspondences to identify fossil animals from fragmentary bones.
Correlation of parts : The principle that an organism’s anatomical structures are functionally interdependent and tend to occur in coordinated combinations. Cuvier used correlated features to infer missing bones and identify fossil animals.
Muséum national d'histoire naturelle : A Paris natural-history institution founded during the French Revolution from the former royal garden and collections. Cuvier taught and conducted much of his research at this influential institution.
Jean-Baptiste Lamarck : A French naturalist who proposed that species change over time through use, disuse, and inherited acquired traits. Lamarck’s transformist account directly opposed Cuvier’s defense of species fixity.
Species fixity : The belief that species remain fundamentally unchanged rather than transforming into other species. Cuvier’s evidence for extinction coexisted with his rejection of species transformation.
Vertebrate paleontology : The study of fossilized vertebrates, including their anatomy, diversity, and history. Cuvier helped establish this field by identifying extinct vertebrates through their fossils.
Principle of the correlation of growth : Cuvier’s principle that an animal’s organs and structures develop in coordination with one another. It underpinned his claim that an organism’s parts form an integrated system.
Jean-Léopold Nicolas Frédéric Cuvier : The birth name of the French naturalist commonly known as Georges Cuvier. This name distinguishes his formal birth identity from the name used in scientific history.
Catastrophism : The view that Earth’s history includes sudden, large-scale events that reshape life and landscapes. Cuvier explained changes in fossil faunas through catastrophic events, though not necessarily a single global flood.
Faunal succession : The ordered appearance and disappearance of fossil animal groups through geological strata. Cuvier used changing fossil assemblages to argue that Earth’s past contained distinct faunas.
