Georges Cuvier (1769 – 1832) was a French naturalist and zoologist and a leader in natural sciences in the early 19th century. He proved extinction occurred. He established that elephant-like bones belonged to an extinct animal, the mastodon, and was one of the first people to suggest the earth had been dominated by reptiles in prehistoric times.
Cuvier believed there was no evidence for evolution, but rather evidence for cyclical creations and destructions of life forms by global extinction events such as deluges.
His most famous work is Le Règne Animal (1817; English: The Animal Kingdom). His name is one of the 72 names inscribed on the Eiffel Tower.
Here are engravings from his work for you to choose from. They are original antiques, made in the mid 1800s.
