Étienne Geoffroy Saint-Hilaire


Geoffroy Saint-Hilaire, about 70 years old One centuries Geoffroy Saint-Hilaire (Étampes (Seine-et-Oise), April 15, 1772 - June 19, 1844) was a French nature researcher, especially zoologist and anatomy who discovered the principle of homologies between different species. He was a colleague of Jean-Baptiste Lamarck and defended and held similar ideas on evolution. The ideas of Saint-Hilaire, like Lorenz Oken, in some ways had a transcendental side, in contrast to Lamarck's materialistic view. Saint-Hilaire believed in an underlying unity in the design of organisms and in the possibility of transmutation of species. Through research in comparative anatomy, palaeontology and embryology, he tried to find evidence for his ideas.
