Before Darwin, most naturalists did not think of themselves as scientists. When they looked at nature, perhaps as explorers, they looked at everything. They looked at the land, the people, the plants and animals. After Darwin, they did see themselves as scientists. Early on, Darwin called himself a geologist. Thomas Henry Huxley was an anatomist. Joseph Dalton Hooker was a botanist. Charles Lyell was a geologist. They changed the way in which they were educated as well. They often took degrees in science. That sort of education was rare before Darwin.
