In what ways did Charles Lyell impact Charles Darwin’s theory of evolution? What type of relationship did Darwin have with Charles Lyell? How did Darwin learn about Charles Lyell's ideas?

They both believed that continuous and gradual change is law of nature

Explanation:

Charles Lyell's “Principles of Geology “ encouraged Charles Darwin to think of evolution of living organisms as a slow process just like the slow geological processes taking place since millions of years. As per Charles, the slow and little contribution of continuous geological events shaped the present geological attributes of the earth. Likewise Charles Darwin’s theory of evolution also earmarked accumulated effects of small gradual changes over immense spans of time. They both believed that continuous and gradual change is law of nature.
