Geoffroy St. Hilaire was a man who worked to prove that evolutionary theory existed, and he contributed to evolutionary thinking by giving ideas to Charles Darwin, as well as other future scientists.

Etienne Geoffroy Saint-Hilaire was a french scientist who mainly worked in the Natural History field. He was a college of the famous Jeah-Baptiste Lamarck, and he supported the theories that he was publishing at the time. In his later life, he was a professor of zoology in Paris, and he later died in 1844 after becoming blind and having a paralytic attack.

Geoffroy was famous for his contributions to evolutionary science when he came up with an evolution theory that claims that the environment is responsible for the change in any organism. It is said that he was one of the first scientists to grasp an important aspect of the evolutionary thinking process, but he was really stretching the evidence when it came to his theory of "Unity of Type." This can be shown by how one of his theories believed that "...the segmented external skeleton and jointed legs of arthropods such as insects were equivalent to the internal vertebrae and ribs of vertebrates..." Geoffroy still believed in god, but he also acknowledged the fact that he lived in a universe that was evolving constantly. It is said that the thinking that Geoffroy had contributed to the thoughts that were developed by Charles Darwin. -http://de.academic.ru/pictures/dewiki/71/Geoffroy_Saint_Hilaire,_Etienne_cropped.jpg -Étienne Geoffroy Saint-Hilaire - Wikipedia, the free encyclopedia.
