What did lyell do for evolution?

Charles Lyell was a prominent geologist whose work laid the groundwork for understanding geological processes over time, which influenced evolutionary theory. His book "Principles of Geology" introduced the concept of uniformitarianism, proposing that the Earth’s features were shaped by continuous and observable processes, such as erosion and sedimentation, over long periods. This idea helped scientists, including Charles Darwin, appreciate the vast timescales necessary for evolution to occur, supporting the notion that species could change gradually through natural selection. Lyell's emphasis on deep time was crucial in shifting the scientific perspective on the age of the Earth and the processes that shaped it.
