Theory of geological change
WebbThere followed a period of 20 extremely exciting years where the theory of continental drift developed from being believed by a few to being the cornerstone of modern geology. Beginning in 1947 research provided new evidence about the ocean floor, and in 1960 Bruce C. Heezen published the concept of mid-ocean ridges.

WebbBroadly speaking, evolution is a change in the genetic makeup (and often, the heritable features) of a population over time. Biologists sometimes define two types of evolution based on scale: Macroevolution, which … 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…
