One of the major debates in evolution concerns the relative contributions of abiotic and biotic factors to macroevolution, and each one of these developments increasingly suggested that it was climatic and geologic factors, rather than competition, that played the primary role in motivating macroevolution. This research was particularly relevant because it considered how species' differentiation across geographic space became translated into evolutionary differentiation through time. What is the content of geography?

Integrating these new methodological developments with important theoretical insights holds major promise for the future of biogeography and charts a pathway connecting past and future discoveries. It looks at their evolutionary history and things like past climate The value of this approach is that it emphasized developing techniques to rigorously analyze biogeographic patterns using phylogenies.

Based on applying the allopatric model, they recognized that change would appear relatively sudden in the fossil record and further would typically occur in narrow, peripheral environments along the margins of the species range. Aristotle was a student of Plato and a tutor to Alexander the Great, who would conquer the Persian Empire as far as India, spreading Greek culture in the process. The idea that humans were modifying the physical environment was also prevalent in the United States. The ancient Greeks were also interested in the form, size, and geometry of the Earth. Evolution: Education and Outreach Evo Edu Outreach. As well as Humboldt, Carl Ritter is also considered as one of the founders of modern geography. Geography. Geography, the study of the diverse environments, places, and spaces of Earth s surface and their interactions. It seeks to answer the questions of why things are as they are, where they are.

By the beginning of twentieth century there was growth of geographic knowledge in the form of man-environment relationships. Peterson AT, Sobern J, Snchez-Cordero V. Conservatism of ecological niches in evolutionary time. 3. They recognized that most species throughout their history, often many millions of years, were stable and displayed what they termed stasis (Eldredge 1985). But today geography is more interactive as it studies man-environment relationships from different perspectives and in different contexts. WebWhen we trace these modern-day species through evolutionary history, we see patterns of trait evolution that are driven by the continental shifts of the Late Cretaceous, similar to This work continued to be a standard geographic reference for about a 100 years.

This gap led to the quantitative revolution, which was one of the major turning points of modern geography. Researchers now began investigating process rather than a mere description of the event of interest.
