He was a Scottish naturalist and farmer who came up with the Principle of Uniformitarianism. He is considered the person who developed the idea of geologic time and proposed that the Earth was much older than people thought at the time.

According to this Principle, geologic processes that occur today are similar to those that have occurred in the past.
