Content created: 060707 File last modified: 150712 Quick Essays on Theory As a general term, the word evolution (from Latin evolvere, to unroll ) simply refers to gradual transformation over time. We say that Latin slowly evolved into the modern Romance languages, for example. Or that cell phone etiquette, Russian foreign policy, teen fashions, and the AIDS virus are rapidly evolving. We speak of a person's viewpoint evolving over the course of a lifetime. Not all gradual changes are necessarily called evolution. We don't normally speak of a flower wilting, wallpaper fading, or a nail rusting as evolution. The concept refers to change, but not normally to change which is merely deterioration. Similarly we don't usually use the phrase for changes which are mere fluctuations, such as the rise and fall in the price of a stock. This essay considers three kinds of evolution that have had theoretical significance in university pursuits: Linguistic evolution (which forms an intellectual background for other models of evolution), biological evolution (where the idea has been most interesting), and cultural evolution (where the idea has never worked very well). Page Outline: I. Linguistic Evolution Methodical comparisons among European languages, and between these and Indian languages, resulted by the early 1800s in the creation of a formal model of the process. The most frequently cited study is by Jacob Grimm — of Brothers Grimm fame — who in 1822 formulated Grimm's Law describing sound changes regularly occurring over time as the Germanic languages emerged from an earlier common ancestor. (It was modified to something like its modern form by Karl Adolf Verner, who in 1875 demonstrated the interaction of Grimm's law with regularities in syllable stress.) Among other things, the concept of linguistic evolution.

Such as, Uniformitarianism, Catastrophism, Gradualism, and Punctuated Equilibrium. Generally, Uniformitarianism and Catastrophism are grouped together while Punctuated Equilibrium and Gradualism are grouped together separately from Uniformitarianism and Catastrophism. Gradualism and Punctuated Equilibrium are usually looked at through a biblical stand point rather than how Uniformitarianism and Catastrophism are looked at from the opposite view.   [tags: Evolution] :: 3 Works Cited 615 words(1.8 pages) Better Essays [preview] Proof of the Existence of Evolution - Since the publishing of Charles Darwin’s Origin of Species, where the theory of evolution has arisen from, people have debated Creationism versus Evolution. Through supporting facts and statements the theory of evolution will be defended as being more than just a theory, and proven as fact. Evolution as a fact is reinforced through; scientific studies on DNA, genetics and its mutilation, the Fossil Record and the change in earlier species that has been found, and finally the distribution of related species of animals over a broad geographical range.   [tags: evolution] 625 words(1.8 pages) Better Essays [preview] Theory of Evolution - Man could not evolve to any other state, because he was made in the ultimate state. He was made in the image and likeness of the Father so there was no need for evolution; hence, there was no sign.
any people do not understand current ideas about evolution. The following is a brief summary of the modern consensus among evolutionary biologists. The idea that life on Earth has evolved was widely discussed in Europe in the late 1700's and the early part of the last century. In 1859 Charles Darwin supplied a mechanism, namely natural selection, that could explain how evolution occurs. Darwin's theory of natural selection helped to convince most people that life has evolved and this point has not been seriously challenged in the past one hundred and thirty years. It is important to note that Darwin's book The Origin of Species by Means of Natural Selection did two things. It summarized all of the evidence in favor of the idea that all organisms have descended with modification from a common ancestor, and thus built a strong case for evolution. In addition Darwin advocated natural selection as a mechanism of evolution. Biologists no longer question whether evolution has occurred or is occurring. That part of Darwin's book is now considered to be so overwhelmingly demonstrated that is is often referred to as the FACT of evolution. However, the MECHANISM of evolution is still debated. We have learned much since Darwin's time and it is no longer appropriate to claim that evolutionary biologists believe that Darwin's theory of Natural Selection is the best theory of the mechanism of evolution. I can understand why this point may not be appreciated by the average non-scientist because natural selection is easy to understand at a superficial level. It has been widely promoted in the popular press and the image of survival of the fittest is too powerful and too convenient. During the first part of this century the incorporation of genetics and population biology into studies of evolution led to a Neo-Darwinian theory of evolution that recognized the importance of mutation.

Evolution and Genetics Evolution and Genetics ASHG, Information and Education Committee The teaching of evolution, the unifying concept for all of biology, increasingly is under attack in the United States and several other countries, as critics try to discredit the theory itself or attempt to introduce unscientific alternatives such as intelligent design theory into the science classroom. Genetics and evolution are intimately related, so much so that it is difficult to understand one without some understanding of the other. In fact, many members of ASHG work directly on evolution-related research problems, and it is safe to say that the work of virtually all other members is informed in one way or another by evolution theory. This series of essays, all by ASHG members, demonstrates the historical, conceptual, and practical connections between genetics - especially human genetics - and evolution. We hope that these essays will help our readers see more clearly the centrality of evolution theory to biology and its importance for science education while providing as well some insights into the diverse interests of our members. We welcome your feedback and questions, which you can submit by emailing Katherine Lontok.   ASHG celebrated Darwin's 200th birthday with an afternoon of fun, inquiry-based educational activities at the ASHG/FASEB office in Bethesda, MD.

In this unit, you have learned how traits are passed from parent to offspring and how over time, these traits can change in a process called evolution.  This web-quest is designed to help you pull together all of your genetics and evolution facts into a single well-written essay that summarizes your knowledge and your ability to connect the two.
