Does the theory of uniformitarianism support natural selection? How are biodiversity and evolution related? Which of the following best describes evidence that an evolutionary biologist would not use to support the modern concept of evolution? (a) Two closely related species are found in diff...
Darwin's acceptance of "universal laws of nature" is consonant with Leyll's view of invariant natural laws (uniformitarianism), but at the same time, owing to their tendency towards change, living entities are considered to be without constant structures - an outcome of Darwin's nominalist ...
Cuvier believed in a catastrophe, which meant that these changes and extinctions in nature happened suddenly and violently – see extinction. James Hutton and Charles Lyell opposed Cuvier’s argument with the idea of uniformitarianism. This theory says that changes occur slowly and accumulate ...
Who proposed the idea of geographic isolation? What if Pangea still existed? Which came first: uniformitarianism or catastrophism? What is the physical geography of West Africa like? What hominids developed during the Old Stone Age? Who discovered Heard Island?
of the volcanic nature of rock greatly advanced uniformitarianism, for catastrophist theory had maintained that all the earth's rocks and land had long before precipitated from a primordial ocean. yet this pioneering vulcanist overlooked the seemingly obvious connection between coral reefs and ...

The notion that the Earth might be influenced significantly by external forces has always been a rather disquieting concept for geoscientists who are trained to think in terms of uniformitarianism. The mass extinction debates of the last 15 years and the strong disagreement among advocates of impact...
Who came up with the out of Africa theory? What is the largest island in the Antilles archipelago? What is Pangea Ultima? What is the principle of fossil succession? What does the principle of uniformitarianism state? How are continental islands formed? Which scientist proposed the first formal...
