The concept of uniformitarianism, which posits that the Earth's geological processes operate in the same manner and at the same rates over time, was proposed by Charles Lyell. This idea fundamentally shifted the understanding of Earth's history, suggesting that the features we see today are the result of continuous and gradual processes rather than catastrophic events. Lyell's work emphasized that by studying current geological processes, one could infer the conditions under which past geological formations were created. This framework allowed for a more comprehensive understanding of Earth's history, providing a scientific basis for geology that was instrumental to the development of evolutionary theory. The ideas of other scientists mentioned, such as Cuvier, who is known for catastrophism, and Lamarck and Darwin, who are associated with biological evolution, do not relate directly to the concept of uniformitarianism in geology.
