Webb10 juli 2024 · Charles Lyell was one of the most influential geologists in history. His theory of uniformitarianism was a great influence on Charles Darwin. Lyell theorized that geologic processes that were around at the beginning of time were the same ones that were happening in the present as well and that they worked the same way. 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… Webb28 maj 2024 · The theory of uniformitarianism states that the Earth is shaped by forces like erosion and sedimentation, which are uniform over time.
