GEOFFREY ST. HILLAIRE from Jean Ignace Isidore Gerard - Hetzel P.J. 1842. "Scenes de la vie privee et publique des animaux vignettes par Grandville". p201. Geoffrey St. Hillaire cartooned as a sad philosophical ape - (his theories of evolution) while a disapproving Baron Cuvier looks over his shoulder. Etienne Geoffroy Saint-Hilaire,15 April 1772 – 19 June 1844 was a French natural scientist whose principle of "unity of composition" saw all animals as conforming to the same plan,but with certain organs extended at the inevitable expense of others. As a colleague of Jean-Baptiste Lamarck he expanded and defended Lamarck's evolutionary theories - but they were not fully is own views. He saw evolution as a working out of potential of an animal under the influence of environmental conditions over time,rather than from striving as Lamarck did. Geoffrey's view bought conflict with Cuvier | |
