What is uniformitarianism?
Uniformitarianism (proposed by English geologist Charles Lyell in the 1830s) is the theory that geologic processes that gradually shape Earth are slow and uniform through time…. Lyell based his theory on Scottish geologist James Hutton's theory of gradualism, which states that landforms resulted from slow changes over a long time. In other words, uniformitarianism is the belief that natural laws and processes today are essentially the same as they always have been on Earth. "The present is the key to the past." (MORE)
