Georges-Frédéric Cuvier (; 28 June 1773 – 24 July 1838) was a French zoologist and paleontologist. He was the younger brother of noted naturalist and zoologist Georges Cuvier.
Although an advocate of the inheritance of acquired characteristics, similar to his brother he denied the transmutation of species. He believed that behavioral patterns in animals change over time in relation to environmentally induced needs. Historian Robert J. Richards has written that Cuvier "did not believe that the anatomical patterns of species were modified over time (though he did admit they changed in nonessential ways through the inheritance of acquired characteristics... He was a behavioral evolutionist, if a modest one."
