Étienne Geoffroy Saint-Hilaire (15 April 1772 – 19 June 1844) was a French naturalist who established the principle of "unity of composition". He was a colleague of Jean-Baptiste Lamarck and believed in the underlying unity of organismal design, and the possibility of the change of species in time. He collected evidence for his claims in comparative anatomy, paleontology, and embryology.
