), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Then they use logical reasoning and some imagination to develop a testable idea, called a hypothesis, along with explanations to explain the idea. Lunar eclipses occur when the Earth casts its circular shadow on to the moons surface. Trace the evolution of geography as a distinct discipline? Notably, phenomena akin to allopatric speciation were described before Darwin's voyage on the Beagle; for instance, by Leopold von Buch in 1825, based on his work in the Canary Islands. The Society is the largest Geographical Society in Europe and one of the largest in the world. Dawkins R. The selfish gene. 2009b;2:1505. Some of the principal areas of study in human geography include human society and culture (social and cultural geography), behavior (behavioral geography), economics (economic geography), politics (political geography), and urban systems (urban geography). the most important change which has occurred is the realization that any progress in understanding phenomena studied by geographers involves the conscious use of scientific methods and the development of a body of theory to explain such phenomena. (Graves, 1975) With advanced technologies, wider geographical research will also be capable and new discoveries will be made. Google Scholar. Alexander Von Humboldt was a All this information gives you important clues in understanding man-environment relationship. These ranges change through time but do not show a statistical association with one another and instead appear to be associated with changes in the environment, from Myers and Lieberman (2011), used with permission. They also promoted geography in schools and universities, leading to the first university lecturer appointed in 1888. Eratosthenes calculated the equatorial circumference to be 40,233 kilometers using simple geometric relationships. On the variation of species as related to their geographic distribution, illustrated by the Achatinellidae. Physical geography attempts to determine why natural phenomena have particular spatial patterns and orientation. This article is distributed under the terms of the Creative Commons Attribution 2.0 International License ( NA TURE OF GEOGRAPHY AS A DISCIPLINE In other words, it is the sociological study of cities and their role in the development of society. Like other research methods, it also asks you to explore, analyze, and act upon the things you find. We've received widespread press coverage since 2003, Your UKEssays purchase is secure and we're rated 4.4/5 on reviews.io. Of course, the dynamics of the MOIs vary by discipline. [1] This research was particularly relevant because it considered how species' differentiation across geographic space became translated into evolutionary differentiation through time. Geographys strength comes from its ability to connect functional interrelationships that are not generally noticed in narrowly defined fields of knowledge. I will research past events and influences, to see how they have affected geography as an idiographic subject and changed the subject into a spatial science and effectively into a core academic discipline. Vrba ES. Wiley EO. WebThe academic discipline of geography is extremely broad in subject matter and approaches; it contains specialists covering diverse subjects but sharing concerns over places, spaces, and environments. Biogeography is the discipline of biology that studies the present and past distribution patterns of biolog-ical diversity and their underlying environmental and his-torical causes. He developed the skills of cartography. At this time, geography had no documented split between the human and physical side. Gulick JT. 1. Chapter 3 Planet earth and Plate tectonics, 8. The Romans also made several notable additions to geographical knowledge. Evolution: Education and Outreach For example, the study of the enhancement of the Earths greenhouse effect and the resulting global warming requires a multidisciplinary approach for complete understanding. Vrba (1980, 1985, 1992) essentially extended vicariance biogeography directly into the realm of evolutionary theory by focusing on the significant role that climate change plays in causing evolution via the mechanisms of geographic isolation and allopatric speciation. spatial nature of human and physical features of the Earth. Geography In Greek language the word Ge means the earth and Graphienmeant to write or describe. Peterson AT, Sobern J, Snchez-Cordero V. Conservatism of ecological niches in evolutionary time. Behaims invention was a significant advance over two-dimensional maps because it created a more realistic depiction of the Earths shape and surface configuration. exploration, discovery and conquest through the voyages of Vasco da Gama and The naturalist Charles Darwin wrote a book called the Origin of the Species by Means of Natural Selection in 1859. Myers and Lieberman (2011) specifically focused on whether there was any evidence for competitive replacement: a phenomenon where one species appears within another species' geographic range, its range expands, and it slowly and gradually drives the other species to extinction.

Ptolemy was also a great map maker (cartographer). Al-Idrisi is best known for his skill at making maps and for his work of descriptive geography Kitab nuzhat al-mushtaq fi ikhtiraq al-afaq or The Pleasure Excursion of One Who Is Eager to Traverse the Regions of the World. Ibn Battutah and Ibn Khaldun are well known for writing about their extensive travels of North Africa and the Middle East. commissioned by a number of Nations in Europe (Figure. This revolution began in the 1950s, and marked a swift change in the method behind geographical research making geography into a spatial science and shifting from an idiographic subject to an empirical law making one. Provided by the Springer Nature SharedIt content-sharing initiative. As science progressed, certain aspects of science that could not be experimented and sensed awaited the development of new technologies, such as atoms, molecules, and the deep-time of geology. there lived a Greek philosopher named Eratosthenes. The development of geography can be summarised in Both Humboldt and Ritter shared similar views. It was the ancient Greek scholars During this period, geography was primarily focused on describing and classifying the Earth's physical features, but it gradually evolved to include the study of human geography and the interactions between humans and the environment. The discipline has a long and extensive history that extends well back into the eighteenth century and biogeographic research played a pivotal role in the development of evolution, particularly in the works of Wallace and Darwin (Brooks and McLennan 1991; Lieberman 2000; Morrone 2008; Wiley and Lieberman 2011). Mayr E. Animal species and evolution. This is clearly an important mode of allopatric speciation (e.g., Wiley and Mayden 1985; Brooks and McLennan 1991; Lieberman 2000; Stigall 2010; Wiley and Lieberman 2011). can survive in hot or extremely cold conditions due to their ability to modify Paleontology Coyne JA, Orr HA. Species and speciation in phylogenetic systematics, with examples from the North American fish fauna. -24 A.D.), Ptolemy (127-151 A.D.) in their great work Geographia provided a new direction to geography. The pattern of punctuated equilibria not only characterized the bulk of species preserved in the fossil record, but also very much went against the Darwinian notion that species should be changing slowly and gradually over millions of years across their entire range (Eldredge and Gould 1972; Eldredge 1985). This appointment acted as a catalyst, and after this, many other universities started to follow suit. Geography had emerged as a great companion in this respect. The French geographer Paul Vidal de la Blanche opposed this revolutionary idea. Google Scholar. Models in paleobiology. Most of these voyages were financed because of the potential commercial returns from resource exploitation. Evolution. He was the first to use the word geography to describe earth. In this volume, Varenius used direct observations and primary measurements to present some new ideas concerning geographic knowledge. The discipline of geography became more distinct as a subject environment such as low rainfall, high temperatures and poor soils. was the use of quantitative techniques in physical and human geography. Historical Biogeography: Evolution in Time and Space Exploring lifes diversity and geographys effect on it was central to Darwin and Wallaces parallel discoveries of evolution. Mammals as a key to evolutionary theory. In this literature there appears some semblance of cultural and human geography too. Emerging syntheses between palaeobiogeography and macroevolutionary theory. These techniques make it possible to precisely and repeatably calculate the geographic range of individual species using locality information. A simple example of a geographic study in human geography would be where is the Hispanic population concentrated in the U.S., and why? These increases are the result of a growing human population and the consequent increase in the consumption of natural resources. about as a result of the expanding scope of the discipline as well the need to 2023 BioMed Central Ltd unless otherwise stated. Today, this area of knowledge is called cultural geography. The Greek word geographos from which geography is derived, is literally translated as writing (graphos) about the Earth (geo). In the case of fossil species, first fossil distributions from various localities are plotted on a modern map in GIS. The Geography of Evolution and the Evolution of Geography. Pastoralists do very little to modify such natural conditions usually surrender to nature. The Turnover Pulse Hypothesis provided a means of extending punctuated equilibria from the single species case to the multiple species case. The subject of geography can be traced back to hundreds or even thousands of years ago. Measurements of the Earth using modern satellite technology have computed the circumference to be 40,072 kilometers. 1987), where he argued that geographic barriers could serve to isolate populations of species, leading to differentiation. A.V. and his pupils had accepted the round shape of the earth. had described the temperature zones of the earth. physical geography. The primary purpose of these early investigations was to map features and places observed as explorers traveled to new lands. WebGeography can be traced back to Eratosthenes, a Greek scholar who lived around 276-196 B.C and who is often called the father of geography. Abstract.
