Etienne Geoffroy Saint-Hilaire was a French biologist who established a theory of "unity of composition". This principle postulated a major theme of comparative anatomy - that there is a single structural plan shared by all animals. Geoffroy also founded teratology which is the study of animal malformation. Geoffrey initially earned a law degree in 1790 and then studied medicine under Louis Daubenton. The next year, Daubenton appointed Geoffroy as superintendent of the cabinet of zoology at the Jardin des Plantes, a predecessor of the Museum National d'Histoire Naturelle. Geoffroy also accompanied Napoleon on his conquest of Egypt in 1798, contributing to the 24 volumes of the Description de l'Egypte (1809?28; Description of Egypt). He later would transport specimens collected in Egypt to France. Following his appointment as Professor of Zoology at the University of Paris in 1809, his research established a "unity of organic composition". Upon attempting to apply this notion to invertebrates in 1830, French naturalist Georges Cuvier disputed his theory. Geoffroy's theory would create a receptive audience for Charles Darwin's evolutionary theory, but Cuvier opposed evolution.
