WebbAnother of Hutton’s key concepts was the Theory of Uniformitarianism. This was the belief that geological forces at work in the present day—barely noticeable to the human eye, yet immense in their impact—are the same as those that operated in the past. Published in three volumes in 1830–1833 by John Murray, the book established Lyell's credentials as an important geological theorist and popularized the doctrine of uniformitarianism (first suggested by James Hutton in Theory of the Earth published in 1795). The central argument in Principles was that "the present is the key to the past": that geological remains from the distant past co…

Webbhimself. ‘Deep time’ was a key element of the theory of natural selection, because slow, gradual biological change, which might transform the earth’s biota, could only operate through the immensity of geological time (Burchﬁeld 1974). Thus it was important for Darwin that he provide evidence of the vastness of deep time.

"WebbThe next big advancement, and perhaps the largest in the history of geology, is the theory of plate tectonics and continental drift. Dogmatic acceptance of uniformitarianism inhibited the progress of this idea, mainly because of the permanency placed on the continents and their positions. " - Theory of geological change
