His theory of uniformitarianism was a great influence on Charles Darwin. Lyell theorized that geologic processes that were around at the beginning of time were the same ones that were happening in the present as well and that they worked the same way.

WebbIn the natural sciences, gradualism is the theory which holds that profound change is the cumulative product of slow but continuous processes, often contrasted with catastrophism.The theory was proposed in 1795 by James Hutton, a Scottish geologist, and was later incorporated into Charles Lyell's theory of uniformitarianism.Tenets from …
