How did Charles Lyell's ideas build on James Hutton's work?

Charles Lyell was a principal proponent of the uniformitarianism initially established by James Hutton. Lyell built upon Hutton’s foundational work by providing extensive observational evidence and a clear methodology for inferring Earth's history from rock successions in his influential work, Principles of Geology.123

While Hutton first proposed that geologic phenomena could be explained by observable, ongoing natural processes over immense time, Lyell expanded this into a more rigid doctrine. Lyell insisted that all past geologic events must have conformed to the same processes and intensities observed today, rejecting the possibility of past conditions that lacked modern counterparts.1432

By championing these principles, Lyell helped the scientific community move away from catastrophism and toward a view of Earth shaped by gradual, continuous change. His work not only solidified uniformitarianism as a fundamental philosophy of geology but also provided a framework that profoundly influenced the development of evolutionary biology.1235
