Detailed explanation-1: -Lyell had an equally profound effect on our understanding of life’s history. He influenced Darwin so deeply that Darwin envisioned evolution as a sort of biological uniformitarianism. Evolution took place from one generation to the next before our very eyes, he argued, but it worked too slowly for us to perceive.
Detailed explanation-2: -Answer and Explanation: Charles Lyell influenced Darwin’s theory of natural selection by providing geological and fossil evidence to support Darwin’s theory. The two became acquainted after Darwin returned from his voyage aboard the HMS Beagle where Darwin served as the ship’s naturalist.
Detailed explanation-3: -Lyell argued that the formation of Earth’s crust took place through countless small changes occurring over vast periods of time, all according to known natural laws. His “uniformitarian” proposal was that the forces molding the planet today have operated continuously throughout its history.
Detailed explanation-4: -What ideas in Lyell’s theory of uniformitarianism were important for evolutionary theory? He inferred that similar changes had happened in the past. Uniformitarianism combines the idea of gradual change over time with Lyell’s observations that such changes have occurred at a constant rate and are ongoing.
