How Did Lydell's Theory Contribute To The Discovery Of Uniformitarianism?

There were several advances throughout time that helped determine the earth’s age. James Hutton created a theory called “Plutonism” the cycling of heat, which produces formations of rocks on top of rocks to create the layers of earth’s surface. In result, plutonism lead to the discovery of uniformitarianism. Uniformitarianism is the theory of all natural laws and elements that help to form the earth, continue to exist and function in the present as they have in the past. This theory later led Charles Lydell to example his theory “the present is the key to the past” which turned out to be one of the most significant impacts on the way science study the earth and the universe.
Lydell’s theory led to the discovery of biological evolution; allowing
