Evolution Creationism Term Paper

… Evolution and Creationism

In the early 1920's the older Victorians, called Traditionalists, became alarmed at the social chaos they found in society, with Intellectualism, women beginning to feel less restricted, with jazz, dancing the Charleston, smoking, drinking, flaunting prohibition, abstract art, Freudian psychology and no one asking permission to do anything. The Traditionalists felt that everything valuable was slipping away. A wave of Revivalism swept the South to counteract Modernism and Intellectualism. There was conflict between the liberals and the conservatives in society, between the Evolutionists and the Fundamentalists. Things came to a head in the small town of Dayton, Tennessee, when John Scopes, a high school biology teacher, was tried for teaching the theory of evolution. The trial was widely covered by the most famous broadcasters in the nation. In the trial, also called the "Scopes Monkey Trial," it was decided that it would be legal to teach evolution in the public schools. (Futuyma, 1982)

More recently, "Creationists" have brought up the issue again, trying to get a religious theory accepted back into the public school curriculum. The Fundamentalists want "Intelligent Design" taught in the classrooms, rather than "Darwinism," a term meaning "Evolution," which is now the dominating theory espoused by science teachers and biologists. (Darwin 1962) Today, the social scene is similar to the 1920's, in that Fundamentalists are alarmed at the apparent licentiousness in society today. Young people seem to be out of control, the nation seems to be moving away from its roots, the core American family is hard to find and religion is on the wane as fewer and fewer people go to church. The Neo-Creationists, however, are not like their forbearers in that they do not believe in a young earth (only a few thousand years old) or in a literal interpretation of the Bible. These Fundamentalists simply reject naturalism, as opposed to supernaturalism in the beginning of life, and oppose an atheistic "scientific method" as the means of natural selection and other scientific phenomena. They want religion to be an alternative choice for young people who study the universe.

Darwin is described by the Stanford Encyclopedia of Philosophy as:

distinctive form of evolutionary explanation for the history and diversity of life on earth. Its original formulation is provided in the first edition of On the Origin of Species in 1859. This entry first formulates 'Darwin's Darwinism' in terms of five philosophically distinctive themes: (i) probability and chance, (ii) the nature, power and scope of selection, (iii) adaptation and teleology, (iv) nominalism vs. essentialism about species and (v) the tempo and mode of evolutionary change. (Darwinism, 2004)

Darwin was a man who travelled the world observing biolog in plants and animals. As he travelled and observed, he found he was dealing with a mechanism of natural selection, as some species were able to survive in certain environments while others died out, but were those that died out were still able to in kinder environments. This observation grew into his theory of Natural Selection, in… [read more]


Evolution vs. Creationism Biological Term Paper

… Most people view religion as based on faith rather than fact and anything that can concretely disprove the creation of the world and of man, as Creationists believe, will destroy the entire foundation of religion itself. While the evolution theory concerns itself only with how life on Earth has progressed and varied since the first life form, Creationists have targeted more than one feature of the theory: first, that man and ape had a common ancestor (Bakke); then that the questionable use of the word "theory" and, later, of evolution as a concept itself. And recently, the Pope released a statement that evolution is, after all, not in conflict with the Church's teaching about creation.

It must also be pointed out that the evolution theory as a theory is not a mere guess or speculation, but a fundamental one, which is sufficiently backed by empirical or demonstrable evidence.

Even the law upholds the evolution theory. It will be remembered that the teaching of the theory was outlawed in Tennessee in the 1920s, through the Scopes trial. Then in the 1970s and the 1980s, laws were made, requiring the teaching of science in more than 20 states, but only Arkansas and Louisiana passed these laws. Later, a federal district court overturned this law in 1982 and the U.S. Supreme Court did the same to the Louisiana law in 1987, which required that evolution be taught only with a "balanced treatment" of the creation theory (youdebate.com). It decided that creationism is not a science and, therefore, cannot be taught in public schools as an alternative, or in addition, to the theory of evolution. It, however, allowed religious creation stories in philosophy, religion and history (O'Neill).

In effect, this Supreme Court ruling could neither prevent public schools from teaching the creation theory nor ban the teaching of the evolution theory. Both subjects are taken off the standard tests of public schools, and the local school board decides what should be taught (youdebate.com).

The basis of this ruling was what Nobel Prize winner-scientist Linus Pauling said about science: that it is the search for truth and that what science does is to continuously explore and compare theories in an objective manner, using evidence drawn from the natural world. He emphasized that, when a particular theory fails to conform to evidence, it is either modified or rejected in favor of another theory that conforms. The series of constantly trying assumptions and either accepting or rejecting them is what makes scientific knowledge and understanding grow through time. This test cannot be performed on religion and its assumptions and thus cannot arrive at a concrete, objective understanding of the natural world.

Evolution in 1987, the Supreme Court Essay

… ¶ … Evolution

In 1987, the Supreme Court of the United States ruled in Edwards v. Aquillard. That case was seminal in its importance to the idea of the teaching of Evolutionary theory in the public schools. Since the 1920s, the U.S. Education System has wavered regarding the teaching of creationism vs. evolution in the public schools. In the 1960s, new scientific and teaching standards fueled the debate. Many conservative states attempted to force through legislation that would require the teaching of creationism along with Darwinian evolution. In the early 1980s, a Louisiana law, titled the "Balanced Treatment for Creation-Science in Public School Instruction Act" prohibited teaching evolution unless it was accompanied by a balanced approach in teaching creationism. This essentially forced schools to teach a Biblical belief that life arose abruptly according to Genesis if the school wished to integrate evolution into the classroom.

Louisiana Governor Edwards argued that it did not force the teaching of creationism, but simply required that if evolution was taught, creationism should be taught as well, forming a balanced curriculum. In support of Aquillard, 72 Nobel scientists, 17 state academies of science, and 7 other scientific organizations filed amicus briefs positing that evolution was a scientific theory while creationism a non-scientific explanation based on faith. The Aquillard side did not demean of underhandedly critique the teaching of creationism, but remained convinced that teaching a Biblical theory violated the Constitutional separation of Church and State.

In a 7 to 2 vote the Court ruled against Louisiana and held that the State law did indeed violate the Constitution. Using the Lemon test, the court argued that Louisiana's law failed on all points of the law: First, it was not enacted to test secular purpose. Second, the primary effect of State law was to advance a viewpoint that an advanced being created the universe and it was a series of chemical reactions that occurred to stir life, amid a process of slow change over time to allow species to develop. Further, the Court found that despite the verbiage, the Louisiana law did not protect academic freedom, but in turn required religious beliefs to be introduced into the classroom since modern biology relies on learning evolution as a concept. Dissenting Judges Scalia and Rehnquist wrote that students should be allowed to make up their own minds about topics such as this. This case had a great effect on the American creationist movement, who now sought to redefine and package its views as "Creation Science," even though there is no science involved. It also contributed to an upsurge in the antipathy between evolutionists and…… [read more]

Evolution in the Book Essay

… According to this idea, God created man and then women out of Adam's rib. There is no scientific proof behind this viewpoint because it is not based on any scientific evidence. It is instead a theory based on the religious teachings of people.

Not just animals are prone to evolution and adaptation, but so is the larger world on the whole. Humans of course can evolve and have done so from millennia. In addition plants can survive if they are attempting to be grown in an area which has proven to inhospitable to them. A cactus, for example, is grown in the desert but has needed to adapt to drink less water in order to survive in this hash climate. If the plant did not have the ability to do this, then it would very quickly die.

Even the large world has been proven to change, to break apart, and to move away. It is believed that the world was once part of a whole, unified continent which is now known as Pangaea. On this continent, all the lands were connected. However, due to the separation of the continents there are now seven distinct continents as they are known today. The theory of Plate Tectonics discussed how the continents, due to earth activity such as earthquakes or flood, has created seven distinct localities. What is more, on the different continents, fossils from the same historic period have been located in countries and continents around the globe, indicating that the animals had once lived in the same vicinity. Through each rock layer, anthropologists and geologists have indicated how long a certain animal have been deceased in each part. Similarities in the parts indicate pairs of fossils, giving evidence to both sides of the tectonic myth.

Intelligent Design and Evolution Theory Essay

… Intelligent Design vs. Evolution

Arguing for Intelligent Design

Intelligent Design (ID) is a process that advocates believe explains the features of the universe. In the theory of ID, the features of the universe had to have been created by an intelligent source, "…not [by] an undirected process such as natural selection," according to the Center for Science & Culture. By analyzing the components of a system, a scientist can theorize as to whether the "natural structures" seen in the universe are the product of natural law, pure chance, or intelligent design -- or perhaps a combination of all three. Scientists working with the ID theory are always searching for objects that have similar properties as other objects found that do indeed provide information on their intelligent origins.

Unlike creationism, ID does not claim that "…modern biology can identify whether the intelligent cause detected through science is supernatural"; and moreover, the "scientific method" known as intelligent design involves observations, hypothesis, experiments and conclusions, like any other scientific method of research (Discovery Institute).

There can be no argument to negate ID when observing the eye of a snapping turtle for example; the turtle's eye could not have evolved in a "stepwise fashion" because it is made of several interacting parts, and removing one part among the several would "cause the entire system to cease functioning" (Discovery Institute). The eye of the turtle must have been created at one time. As for the Cambrian explosion 530 million years ago, there was a sudden appearance of biological diversity that could not possibly have appeared in a step-by-step process such as Darwin described. For example, the predatory Anomalocaris (a large, aggressive shrimp-like creature) appeared (according to fossil records) in a very short time frame. How can evolutionists explain the sudden appearance of the Anomalocaris?

Arguing for Evolution

Response to Creation and Evolution Term Paper

… ¶ … Evolution

Few topics stir more passionate debates than the theories of evolution and creationism. However, there are atheistic evolutionists and there are theistic evolutionists, who accept a compromise between creationism and evolutionism.(Evolution). In its true form, evolution explains that the universe is the result of random accidents, in which life arose through chemical processes, meaning that all life-forms, from fruit to flowers, animals to humans, share a common ancestor.(Evolution). This theory includes topics that range from chemistry to astronomy to biology that are responsible for the creation of the universe (Evolution).

From the Big Bang theory has emerged the Inflationary Universe Theories, which include approximately fifty different variants, although generally they all claim that in the beginning there was nothing and then suddenly a "singularity" appeared and exploded, laying the foundation for basic evolution (Evolution). However, for all these theories, none can claim to be the true explanation of the universe, and none can answer what was there before there was "nothing" or what or where the "nothing" originated.

According to a 2004 Gallup Poll, forty-five percent of Americans believe that God created human beings, approximately 10,000 years ago, while some thirty percent believe that Charles Darwin's theory of evolution is a well-supported theory, another third believe that the Bible is the actual word of God and is taken literally, word for word (Vitaska 2005).

According to the Chambers 20th Century Dictionary, "creation is to bring into being or form out of nothing," something that humans cannot accomplish (Redditch 2002). This is the typical argument presented by creationists, who somehow relate evolution to a man-made event. However, theory of evolution is just as mysterious as the theory of creation, both are attributed to an event that simply "happens," whether by God's divine order, or simply by a cosmic event, yet in each, man is the eventual outcome, not the reason or cause.

Human Evolution Is the Origin Term Paper

… Neanderthals skeleto-muscular system indicates that the species was robust and heavily muscled; distinctive facial features are characterized by a protruding mid-facial region. Though Neanderthals' heights are comparable those of modern humans, analysis of the Neanderthal pelvic bones indicates that Neanderthals pelvic bones were significantly longer than those of modern humans.

There are several conflicting hypotheses have been formulated in an attempt to explain the extinction and/or disappearance of Neanderthals. One such hypothesis formulated insinuates that Neanderthals became extinct due to climate changes or interaction with humans. It is also believed that Neanderthals interbred with H. sapiens and disappeared through absorption. Another hypothesis is that the Neanderthal disappeared due to a major natural disaster such as the Campanian ignimbrite volcanic super-eruption.

It is believed that modern humans' extended maturation may be an advantageous factor over Neanderthals. This extended maturation may have facilitated learning and complex cognition. Furthermore, evidence has been produced to indicate that overall development in Neanderthals was significantly faster than that in H. sapiens.

Modern scientific and anthropological discoveries continue to contribute to the study and understanding of Neanderthals as a society and a species or sub-species. Though differing perspectives on how Neanderthals lived and died will continue to arise, these differing opinions provide insight into how Neanderthals may have lived.

Which One Science or Religion Research Paper

… Religion has been on the losing side of a prolonged conflict with the secular world for the past two centuries. However, since the September 11 attacks by Muslim terrorists at the World Trade Center, religious terrorism has been regarded as the most dangerous threat to the Western world since the Soviet Union. Countless political leaders, scholars, and journalists criticized the aggressive Islamic fundamentalist doctrines which guided these Jihadist warriors into their suicide missions.

Many intellectuals drew parallels between the purification mission of Islamic fundamentalists and the apocalyptic obsessions of the U.S.'s own fundamentalist evangelicals, some of which were in important government office. Indeed, it appeared that religious fundamentalists from Christianity, Islam, and Judaism had hijacked important government offices, possibly bringing about the decline of Western Civilization into another Dark Age and reversing the tremendous gains made by the intellectuals and scientists of the Western World.

Review of Sources

The essays below all involve a science-religion dispute of some sort but focus on different aspects of it. Ruse, Demere/Walsh and Glynn all address the most controversial recent debate in the science-religion conflict: the validity and value of Creationism as a scientific theory. Begley addresses a much more abstract issue which is the convergence of science and religion in the nature of their inquiries. Finally, Zindler addresses the effect of Evangelical Christian doctrine on its adherents' decisions by analyzing the many follies of former President George W. Bush.

a. Michael Ruse -- Evolution and Creationism Both Contribute to Human Understanding

Ruse argues that science and religion, through constructive dialogue, could moderate the excesses of each other. Religion can moderate the hubris of scientific ambition and science can explain the technical workings of the universe. His most compelling piece of support in favor of Religion is Augustine's theory of creation, the metaphor of God planting seeds which were to grow living beings and populate the Earth. Evolutionism and Creationism are possibly compatible as he suggested with his reference to Augustine's "seed" metaphor.

b. Sharon Begley -- Both Religion and Science Can Reveal Life

Begley argues that science has reached the point where it is starting to ask the same questions that religion has been asking for millennia. Some areas of science have encountered phenomena for which they do not have the tools to explain, such as Einstein's discovery of the "spooky" processes of particles in the field of Quantum Mechanics. These discoveries alarm scientists because they defy, or at least complicate, many fundamental laws of the universe long considered absolute by the scientific community. Conversely, unexpected discoveries in the fields of astronomy and cosmology are helping us to make sense of our existence in the universe, providing valuable "solace and support" in an increasingly threatening universe.

Convergent Evolution Essay

… Convergent Evolution

Throughout nature, many organisms can be found that exhibit highly similar characteristics. The bones found in the human hand are similar to those in the pectoral fins of whales and those in the wings of a bat, for example. This is an example of divergent evolution -- all of these structure have the same root in evolutionary history, and developed into different arts as the various organisms grew apart from each other. Another process that takes place in evolution, and that is in many ways even more surprising and compelling, is convergent evolution. This refers to similar structures developing in evolutionary separate sources, or "the development of similar characteristics by taxonomically different organisms" (WGBH 2010). Unlike the similar but different characteristics of hands, fins, and wings, convergent evolution leads to characteristics that are far more similar, but develop from far different evolutionary sources.

One recently discovered example of convergent evolution exists in the White Sands desert of New Mexico. Here, researchers have found three varieties of lizard whose species exist in dark-formed varieties across most of the Southwestern United States, but that are basically white-skinned in the desert (Fountain 2010). The three lizard species have been evolutionarily distinct from each other for some time, but each species developed the same characteristic -- i.e. white skin -- in the six-thousand years or so that have passed since the deserts of this area became white. These lizards are a clear example of convergent evolution, as the same characteristics appeared in a very short evolutionary time period from three completely separate taxonomic branches of the evolutionary tree.

Another example of convergence comes from butterfly wing pattern mimics of their surroundings.…… [read more]


Darwinian Evolution Tragedy of the Commons Essay

… Darwinian Finance

The Evolution of a Financial Crisis

Not a day has passed in the last several months that some news regarding the current global financial crisis has been released. The situation is still the primary focus of all major media outlets, and is also at the forefront of many individuals' minds. At the heart of the focus on this situation is the search for someone or something clear to blame for the sudden collapse of the global economy. This clarity will most likely never emerge, however. The causes and effects of such a situation are enormously complex, and can never be truly known with any certainty. That does not mean that there aren't useful ways to understand the situation though. One way to view the issue is as an example -- non-traditional, perhaps, but relevant nonetheless -- of Darwinian evolution through natural selection. Before such a paradigm can be applied to an economic situation, however, a basic understanding of the principles upon which Darwin (and most of the scientific community) believed the evolution of a species -- that is, a certain organism filling a specific niche in an ecosystem -- was effected.

Darwin, incorporating Malthus' theory of population growth into his own observations, believed that evolution took place over time with minor changes in each generation due to natural selection. All members of a species in a given area will enter competition when the resources needed for survival are limited. Furthermore, he theorized (with help from Malthus) that populations would continue to grow until available resources were not enough to support them all. It is here that selection takes over; different attributes of given individuals within a certain population of a species will have greater or lesser advantages at obtaining food, defending themselves against predators, and/or attracting a mate, all of which affect…… [read more]


Pierre Teilhard's Understanding of Evolution Links Christian Essay

… ¶ … Pierre Teilhard's understanding of evolution links Christian and scientific understandings?

Rather than seeing Christianity and science as fundamentally incompatible, the Catholic theological Pierre Teilhard attempted to link the two in his understanding of material and human complexity and consciousness. Tielhard believed that the universe by its very nature had a tendency to strive to become more complex, as manifested in evolutionary evidence. In other words, from protozoa to patterns in mammal development, species evolve into more complex systems, which create the appearance and reality of an evolution of species. There is a divine impetus in this greater complexity that is reflected both in the Bible and in scientific records that justify Darwin's theory of evolution, such as fossil records. Human thought, in parallel and in consort with human biology (including human brain development and because of God's spiritual design) also grows more complex in its thought patterns and consciousness. The evidence of God is this pulling of humanity into greater complexity in the form of an as Omega Point.

Mosaic Evolution of Early Mammals Term Paper

… Evolution

Luo, Z., Chen, P., Li, G., Chen, G. & Chen, M. "A New Eutriconodont Mammal and Evolutionary Development in Early Mammals." Nature, (2007) Vol 446; 288-293

Evolutionary research tells us that one of the keystones in the development of modern mammals was the adaptation over the millennia of the mammalian middle ear. The theory being that as the species evolved from its reptilian origins, the delicate bones of the middle ear made the transition from the reptilian lower jawbone and evolved into what we now know as the three small bones in the middle ear. They are the hammer (malleus), anvil (incus) and stirrup (stapes) which are connected to one another in what anatomist term the ossicular chain. While this transition has been theorized about, for the first time a fossil has been found that actually shows signs of the transitional period occurring. This fossil also presents similar transitions occurring in lower lumbar vertebra and thoracic vertebra of the spinal column, another hallmark of mammalian evolution.

This fossil is Yanoconodon allini gen, Class Mammalia, Order Eutriconodonta,

Family Jeholodentidae, or know by his friends as just Yanoconodon. Named for the Yan mountain range in China where he was discovered, and condon which is a typical suffix associated with the naming early mammals referring to the teeth, Yanoconodon is a very tiny mammalian ancestor that lived during the Jurassic period. Weighing in at around 2 grams and about 20 to 30 centimeters long, it is extremely rare that any fossils have survived intact.

The researchers meticulously examined this fossil, which is imbedded in a slab of siltstone and fastidiously mapped all the bone structures. There were certain missing portions so some approximations had to be made regarding those areas, but none that would have impeded the validity of their research. After analyzing all of the dental and skeletal characters of Yanoconodon the researcher determine its place along the chain of evolution and cite it as a close relative of species known as Jeholodens. By doing so they can then make further assumptions regarding its mammalian characteristic and its place in the evolutionary transition of mammals. Jeholodens had some characteristics of early reptiles such as well-muscled and broad rear legs, but its front legs were beneath its belly as in modern mammals. More than likely with this configuration it was able to maintain an upright posture at times, another mammalian transitional trait. This point goes to further demonstrate the reasoning behind another find in the species Yanoconodon, that of the changing vertebrae and spinal structure during this period of mammalian evolution.

The results of their thorough examination of Yanoconodon showed some very tantalizing evidence of a transitional species development from reptile to mammal that had not been seen before. The authors themselves do not explicitly say they have found a "missing link," though they do imply it has that kind of importance. Other researchers are debating the point but they all seem to agree that finding this transitional mammal has…… [read more]


Evolution as Presented by Charles Darwin Term Paper

… ¶ … evolution as presented by Charles Darwin is based on three dynamics: natural selection, competition, and descent with modification. Descent with modification describes how species change, competition describes the pressure to change, and natural selection describes what changes occur.

This abstract makes the claim that natural selection, the process by which animals carrying reproductively beneficial traits slowly alter the genotype of a population by competing successfully, favors those species which are able to effectively adapt to a wide range of environmental changes. These genotypic advantages are obtained through descent with modification, which refers to minor mutations within a species that occasionally produce traits that improve on the "original" species.

The abstract goes on to make the claim that the more modification has occurred, the more fit the organism will be and hence the more favored by natural selection. This is because the changes produced by natural selection under competitive pressure will encourage changes that enable the organism to better adapt to its environment.

Finally, the abstract concludes by explaining that descent with modification produces a lineage of ancestry, so that closely related organisms can trace their lineage back to a common ancestor. The more closely related they are, the closer their common ancestor will be in terms of generations.

Critique

This abstract seems to make the common mistake of personifying evolution. A mindset that thinks of nature as "encouraging" or "trying" to produce a result is…… [read more]


Evolution vs. Creation. One Can Imagine Article Critique

… ¶ … evolution vs. creation. One can imagine how Charles Darwin stirred things up when he developed his theory, considering that the controversy is still so hot today. Recently, Carl Zimmer wrote "A Fin is a Limb is a Wing" for National Geographic, which included an up-to-date look at life's complexity. Biologists are starting to understand how complex structures developed step-by-step from the simplest beginnings. That is, how a gene for a limb in a bat's mole-like predecessor turned a hand into a wing and finally a mammal into the air. Zimmer's article was barely out to readers when Casey Luskin who supports Intelligent Design had written his rebuttal. Intelligent Design believes that nature is too creative to be a natural occurrence, it had to be designed by a more intelligent begin.

It is no wonder that Luskin wrote his comments so quickly. Most of Zimmer's article is a thorough, well-researched and written piece for National Geographic readers -- those individuals who are interested in the sciences and environment, but do not want a highly academic piece with a great deal of jargon and scientific formula. The question, then, is why did Zimmer start out his article with a jab at the Creationists? It could have clearly stood as a well-rounded piece without waving the red flag in front of the bull.

There are several types of articles written for magazines and newspapers -- the news item, the feature article and the editorial to name the major ones. The best journalism is when one does form not fall into the other. News mixed with innuendo cannot be seen as credible -- for who knows what is actually factual and what is assumption? On the other hand, a feature story is a detailed presentation of facts that appears in an interesting form for the purpose of entertaining or informing the average person. Rather than give the opinion of the writer, it weaves together the comments of those who are interviewed. It aims to supplement the bare facts of the news report by giving more detailed information regarding the persons, places, and circumstances that appear in the news column. Once the author's opinion is expressed, then it starts to become an editorial or personal essay. Obviously, the reader can often determine the bias of the publication (and the writer) by who is interviewed and these individuals' comments. However, it is the interviewees' comments, not the writer's that are expressed.

It is not that Zimmer actually writes, "These inane Creationists. What are they thinking?" It is rather that he starts the article off with the debate of evolution vs. creationism and then proceeds on the next 24 pages to show all the reasons that evolution is a working process.

Analyzing the article, there is the introductory two paragraphs that aptly provide the interest and reason for the piece: Readers know now that they will be reading how scientists are learning increasingly more about the complexity of animals. These two paragraphs then lead into… [read more]

Evolution: Darwin Term Paper

… This seems to be a variation that even in natural selection stayed genetically strong in both species. Another example if the flying squirrel, able to soar from treetop to treetop.

Another example is that in the arid grasslands of Africa around 5 million years ago, a species was emerging that walked upright and had smaller canine and molar teeth than those preceding this species. This species survived due to the favorable variations that occurred causing the species to gain use of hands for making tools and weaponry and carrying food into the trees for safety.

"Artificial Selection" is that which occurs purposefully on the part of human choice. For instance if blue eyes are desirable and blond hair then the couple would marry someone with those traits, however, in today's highly technological environment the capacity for picking and choosing traits of the unborn child has become an option. Variation is that which is studied in relation to behavioral aspects of a species and is studied by psychologist and sociologists in the search to learn why species behave as they do.

The study of evolutionary biology is extremely important in attaining an understanding of the governance of principles of "origin" and "extinction" of species. There are no "fixed" elements in biological species as they experience constant changes, adaptations, shifts and even emergency and extinction.

Conclusion:

It has been said that after Darwin wrote "Origin of Species" in 1959 that biology has never again been the same. Because of the ever-changing environment of the species, and the ever-changing adaptations to those changes Psychology and other behavioral sciences will be studying those changes in the species to try and understand the behavior of species.

Evolution What Is Evolutionary Theory Term Paper

… It causes the evolution of a population as a whole and not the evolution of an individual. The natural selection process is supposed to gradually shift the average characteristics of the group over time. However, why most populations demonstrate relatively stable dynamics is a question yet to be answered, and biologists are largely uncertain regarding the processes by which population stability may evolve through natural selection (Mueller et al., 2000: p 1284)

Evidence of Evolution

Evolutionary changes are obviously not observable directly as such changes involve decades and centuries. However, there are other evidential facts that explain and demonstrate the occurrence of evolution. The main sources that evidence evolution includes: fossil records, the geographic distribution of species, embryology, vestigial organs and artificial selection. The fossil record offers the most substantial evidence for evolution. Fossils are the remains of organisms turned into rocks after years of buried preservation under layers of mud. The fossil record illustrates a definite progression from the earliest and original species of single-celled organisms to the first multi-celled organism and from those orgasms to many simple and complex organisms inhabiting the earth today. However, fossil record presents many gaps, as it is probable that only a few species were preserved. Even so, palaeontologists have collected enough fossils to present a comprehensive record of the history and development of life on earth.

Geographic distribution of species, generally called biogeography, is the second main source of evidence supporting the occurrence of evolution. The limited and peculiar nature of species of organisms present in specific geographical areas suggests that organisms, which have migrated from other regions, have evolved into new species, adapting to the new environmental conditions. Embryology is the study of the way in which organisms develop during the early stages of life present another source of evidence for evolution. The embryonic development of many organisms involves very specific events that can be explained only by the evolution of the organism from other species. The repeated occurrence of embryonic features of evolutionary ancestors during the early development of an organism is called recapitulation.

The presence of vestigial organs is also suggestive of the occurrence of evolution. Vestigial organs are the remains of organs, which are generally purposeless to the current species, but were once useful to the evolutionary ancestor. The best example of vestigial organ is the human appendix, a narrow tube attached to the large intestine, which serves no purpose to human beings but are useful to apes, considered the ancestors of humans, for digesting plant material.

Artificial selection, which is essentially the process, used by breeders to produce new varieties, also evidence the occurrence of evolution. Breeders select only those organisms in a species that demonstrate the desired qualities. It is a very evident fact that such selections eventually lead to substantial changes in the species. Artificial selection differs from natural selection in only that in artificial selection it is human beings that determine the characteristics that give an advantage in reproduction, whereas in natural selection it… [read more]


Pearl Jam's Do the Evolution Term Paper

… " Venter argues that we have not evolved enough to think independently, and free ourselves from this herd instinct.

The next verses continue to attack human society, and our need for status and admiration. He notes that we are irresponsible in our actions "I'll do what I want, yet irresponsibly." Further Venter attacks human racism, in the line "Cause we know an appetite for nightly feasts. Those ignorant Indians got nothing on me." Here he suggests that what we see as evolved modern civilization is not much difference from what we would consider to be barbarian civilizations.

The final verse is probably Venter's greatest condemnation of modern society. He says, I am ahead...I am advanced, I am the first mammal to make plans. I crawled the earth, but now I'm higher. 2010 watch it go to fire. It's evolution baby!" Here, Venter suggests that humans, despite being so "highly" evolved, will ultimately destroy each other.

It's interesting that Venter chooses to focus on the social aspects of humans as an attack on humans and the idea of evolution. The idea of social evolution has been a terribly controversial issue in human history, and has shown its head in such ugly ways as the Nazi attitudes and the eugenics controversy.

In conclusion, Pearl Jam's "Do the Evolution" is a modern take on the evolution of mankind. The song critiques the idea that humans are somehow "superior" because they are considered to be the most highly evolved organism on Earth. Venter argues that our herd mentality, and our racism will ultimately destroy us all.

Effects of the Theory of Evolution and Natural Selection Essay

… Charles Darwin's Path To Evolution

Darwin is denoted as father of evolution. In perspective, Darwin developed his evolution theory during the same time as Alfred Russell Wallace, another scientist conducting similar research. However, Darwin accrued respect in science prior writing his article on 'On the Origin of Species'. The article was received with much success where the initial printing was immediately sold out although with wider readership and criticism. Darwin's ideas were accommodated within the scientific world into the business and social worlds (Bortz, 2013). In most cases, Darwin's theories developed into societal transformations.

In his research, Darwin rose to a naturalist status, which gave him an opportunity of studying wildlife from Galapagos Islands. The islands amazed him due to great lifestyle diversity (Workman, 2013). Particularly, he had an interest in diversifying the island's various finches and appreciation of beaks that had high adaptation to particular lifestyles. Darwin hypothesized that nature required some form of processes leading to adaptation and diversity (Workman, 2013). Charles Darwin spent most of his time puzzling out the nature and content of the processes. After the return from his island voyage, he brought with him dead finches that were killed and stuffed on behest. Darwin put his notion in writing one an abstract of 490 pages titled 'On the Origin of Species' in 1859.

Darwin's interpretation of Origin offers a diversified perception to the public. The theory of evolution was well accepted as a content of evolution occurring within the concepts of Darwin's human development steps. However, natural selection mechanisms were solicited as reminders of accepted lifelines (Bortz, 2013). This is because of the points that Darwin admittedly explained. For instance, there were issues of trait management in which parents passed onto children while the process remained unclear. The early 1900's marked the period when the focus and scope of genetics advanced into the intense focus study in which Darwin's natural selection mechanism received deeper scientific support and intense scrutiny. The discoveries from genetics enabled Darwin's theories to gain scientific grounds for observation, as well as the consequences of accepted plausible mechanisms in evolutionary change. Prior genetics reached the scene, the perception of survival for fittest were captured the public's imagination. The ideology also applied to elements of the business world that the structures within the society managed to develop (Frame, 2012).

Darwin observed that all forms of diversity of life across the world emerged from the evolution of common ancestors. The theory went further the deliberations of Lamarck's observation in explaining that the complex creatures had a probable evolution of simpler ones. Ideas of social importunate are implications of fewer important roles among humans with mere relevance of branches of the animal world as compared to separate and privileged lineages (Workman, 2013). The Darwin's theory illustrates that in any population,…… [read more]


Did Darwin Develop the Theory of Evolution? Essay

… DARWIN

What was Wallace really talking about in his 1858 paper and was he convincing?

Darwin and Wallace 1858 papers:

Wallace's role in forming the evolutionary hypothesis

Alfred Wallace has often been credited as a critical influence upon Charles Darwin in encouraging the naturalist to publish his theories on evolution: Wallace was working on his own theory of natural selection at the same time as Darwin, and had not Darwin feared being pre-empted by Wallace, he may not have been willing to share his twenty years' research with the world at the time that he did. Wallace's 1858 letters to Darwin, in which Wallace discussed his work are often cited as evidence that Wallace deserves credit as a 'co-founder' of the theory. However, there are certain critical differences between the two men's lines of thought. Wallace's different emphases and some of his errors in reasoning regarding evolution ultimately support the hypothesis that it is Darwin, not Wallace, who deserves the solitary credit for developing the concept of evolutionary theory. "In 1858, in Halmahera, Wallace wrote his essay on natural selection and posted it to Darwin…Darwin had been working on a similar theory for several years and now faced the prospect of being robbed of glory. [Darwin's friends] Lyell and Hooker arranged a reading for Wallace's paper and for a hastily written one by Darwin at the same meeting of the Linnean Society" (McKae 2013). But even had there not been that inspired 'save' by Lyell and Hooker, the lion's share of the credit must still belong to Wallace.

First and foremost is Darwin's emphasis that evolution is a mechanism that begins with the individual, although over time the effects of individual character are eventually felt in the larger population. In contrast, "Wallace apparently thought selection acted on groups or species" (Montgomery 2009). There is less emphasis between competitions between individuals (even individuals from the same species) for the same resources in Wallace. "Whether selection acted for 'the good of the group' or on individuals was debated for a long time" but today the widespread consensus is that Darwin was right and evolution begins as an individual process through mechanisms particular to the animal such as mutations and competition for mates (Montgomery 2009). Darwin did not believe that evolution supported a higher social purpose for 'the good' of a social organization, even though it might unintentionally have that result, for example, allowing moths with a particular type of coloring to survive in greater number because they could camouflage themselves from predators is beneficial for the species and thus results in a change in the dominant colors of moths in the area. But ultimately, this gives advantage to certain individuals that pass on their traits to their progeny, not 'for the good' of that species of moth.

The two men differed as well in their emphasis on sexual vs. natural selection. Darwin viewed sexual selection as the primary means of enacting changes on a generation by generation basis: most species reproduce sexually,… [read more]

Evolution the General Assumption Essay

… Thus, according to the theoretical underpinnings of the mechanism of biological evolution there is no predetermined biological mechanism or pathway that directs the process of evolution from simple to complex organisms (Carroll, 2001). Random mutations are just that; nondirectional and not predictable changes in the alleles of the population. Natural selection is simply a method which results in the genetic mutations that allows for the adaptation and survival of the population in specific environmental conditions to continue to survive (Carroll, 2001; Gould, 2002). While this process often includes a movement of a population towards more structural complexity, this is not always the case.

An example of such an instance where the process of biological evolution did not result in a more complex organism is that of the hypothesized evolution of snakes. Although no one has ever observed the evolution of any particular animal, snakes are hypothesized to have adapted to specific environments such as long, heavy, grassy, terrains or terrains where they needed to burrow for survival by losing their limbs and in the process of the development of an elongated body also lost the use of their left lung (it is typically rudimentary at best in snakes; Vida & Hedges, 2004). As a result, the theoretical evolution of snakes as a biological population assumes a movement from a more complex to a less complex organism. Accordingly, the concept of biological evolution does not necessarily include a predetermined pathway from simple to complex organisms.

Human Evolution Heading? Research Paper

… Indeed, all students in medical schools must be up-to-date to what the research specialists are undergoing. However, spending time on this kinds of subjects does not improve their every day practice and is not crucial for the treatments that are conducted on a day by day basis.

3. The case of the Blue Fugates

The case of the Blue Fugates in Kentucky is representative for the way in which science can, to a certain extent, improve the lives of people. More precisely, it is rather known the fact that people have a tendency to be scared or at best avoid things or other people they do not know. The Blue Fugates is one such case in which people with a rare disease were in fact stigmatized by the fact that they had a bluish color on their skin. After research conducted on this issue, it turned out that in fact there was nothing special about these people and in fact suffered from medical conditions that in time would be cured. Even so, this community was left outside of the social norm particularly because of a change from the ordinary conditions of men. From this point-of-view, medicine and the evolution of research not only saved those people's lives but also contributed to an improvement of their social and community lives.

An important aspect from the article relates to the fact that race can be seen as a social construction, rather than an acclaimed and proven developmental difference. As per the article, at the beginning of the 20th century the European race was said to comprise of different other races which in fact makes it impossible to establish so many categorical differences between human beings that in effect do not differ to such an extend as to assume they are part of different evolutionary groups. The assumption that people are different cannot be determined by using biology especially given that there is no clear distinction between people around the world. However, the constant attempts to differentiate have motivated racism along history, an aspect which at this point seems no longer appropriate. Race is not a criteria for…… [read more]

Comparative Analysis Cultural Evolution vs. Biological Essay

… Cultural vs. Biological Evolution

Cultural Evolution vs. Biological Evolution

Biological and cultural evolution have many similarities. For instance, they both take place slowly over time. They both result in an organism that is substantially different from its predecessors. We, as humans, have another means aside from biology to use to evolve. In all other species, biology is the sole mean by which they evolve. However, with humans, it has been suggested that cultural evolution does not stand alone from biological evolution. This research will examine the fundamental similarities and differences between cultural and biological evolution. It will support the thesis that cultural evolution has a significant impact on biological evolution, even though they are actually two separate concepts.

It has been suggested that biological changes are a result of cultural changes, for instance the movement from hunter gathers to an agrarian society (Richerson, Boyd, and Henrich, 2010). This forced humans to do different activities during their day. Over time, it has been suggested that this forced a biological adaptation in their digestive tract, their musculature and many other biological features. Others suggest that cultural changes were a result of biological evolutionary changes. This conundrum has plagued anthropologists for many years and at present, there is support for both sides.

One of the key differences between biological and cultural evolution is that biological evolution is slow and happens over many generations. However, and idea can spread rapidly through a society. Many times, it does not even take a day, given the speed of the Internet. Today, cultural changes occur quite rapidly. Even if you go back 10,000 years, learning spread quickly from one generation to another, as a parent learned new skills and taught their children. Biological evolution could never keep up with cultural evolution in higher order creatures.

Support tends to lean towards culture, rather than biology, to account for the wide range of large-scale social behaviors in humans. This study suggests that studying the dynamics of how variations are maintained in large groups explains diversity in human behavior. Bell and McElreath (2009) suggest that cumulative cultural changes resulted in rapid human divergence. They also suggest that these cultural divergences had an effect on biology, as they determined which groups would interbreed with whom. Those who were neighbors were more likely to interbreed than those who were distant. Neighbors were also in direct competition for resources.

Boyd and Richerson (2008) suggested that repeated interactions allow a vast range of stable social equilibrium to occur. Primarily, punishment serves as a stabilizing force, as it attempts to eliminate behaviors that are not in alignment with the norms of the society. The authors provide another example, that of immigration. Immigrants are outside of the norm, they must adapt and normalize in order to fit into society and to be able to provide for their basic needs. This normalization process helps to stabilize society and the cultural norms within it.

It is clear that they do not understand what biological evolution means. By definition, biological evolution is the process in which a new species evolve from existing species over time. (Wikipedia). Biological evolution is the change in organisms over time, often in response to natural selection, such that the descendants are genotypically different from their ancestors. This means that evolution occurs over time as a result of a species adapting to its environment. So, if the human species is going to develop lungs that can detoxify air pollutants, then this is something that will evolve through biological evolution over a specific period of time.

It will be because of evolution and adaptation that the human lungs will develop into lungs that have the capability of detoxifying the air pollution that enters into the lungs. Humans and animals alike have the ability to adapt to their present environment, so over a period of time, the lungs will adapt to the air pollution and will eventually evolve into lungs that can handle the high levels of pollution.

Therefore, biological evolution can be proven by…… [read more]

Dancing to Evolution's Tune

The author discusses natural evolutionary design and the factors behind its success. The drive to feed oneself and appease hunger, and the very strong urge for finding a mate are qualities that are commonly shared by the innumerable species that exist in our world. The delicately balanced neurobiological machinery in man guides and governs all his instinctive behaviors. The essence of all human activities, the purpose of all human endeavors, is to satisfy the eternal quest for happiness. But the search for eternal happiness has been a will-o'-the-wisp. At the root of all this are the genes, the fundamental units of life which control the neurochemistry. The author elucidates the important role of motivation in evolution and how the genes are self programmed to achieve this.

Nature has used happiness as a bait to motivate living beings and to propel them into action. Happiness is thus a reward that man receives when he carries on the duties of maintaining his bodily functions- nourishing himself, procreating and extending his heritage. The genes control the neurochemistry behind the feelings of happiness. On cogitation it is revealed that our basic impulses are meant to serve the main purpose of gene proliferation rather than for our psychological well being as it appears at the outset. Over the last decade scientists have found out the significant role of the neurotransmitter dopamine in giving the feeling of happiness and satisfaction. [Bruno Dubuc] Experiments conducted on mice have confirmed that sustained stimulation of the pleasure centers of the brain makes them forget even the basic need for food. Selective neurons in our brain secrete this neurotransmitter (dopamine) as a reward for our indulgence in certain actions. Thus we are entangled in a vicious cycle of desire, action and satisfaction and develop addictive behaviors. These actions or reward seeking behaviors (eating, sex etc.) facilitate the proliferation of the genes. (Eating maintains the body while sex results in progeny).

However, there is a hidden secret behind this gene-based neurochemical and neurobiological interplay which has continued to drive all living species into actions conducive to their own sustenance, reproduction and the well being of their progeny. Since the want for pleasure, or the search for happiness, is the key factor in the sustenance of evolution and natural propagation, nature designed it in such a way that these wants are never fully satiated. This is one of the key points of the article, which the author emphasizes as the secret behind nature's success. If man derived perennial pleasure from any of his activities such as eating, drinking or copulation it would amount to a grinding halt on the evolutionary process, as there would be no further inclination to act.

Anthropology

Doctrine of Man

Man is still searching for answers to the fundamental questions concerning the why and how of his existence, the purpose of the journey of life and the ultimate destiny.

Different theories have been put forward in explaining the origin of man ranging from creationism to evolution. The evolutionary theory of creation attributes all this diversification and the countless species of living beings to the process of systematic natural evolution. The Christian faith offers a different explanation in the form of the genesis account of creation. Even within the creationism theory there are mildly different views of the creation process. A brief discussion of these differing perspectives of creation would shed more light on that one primeval question which has continued to intrigue all of mankind from time immemorial.

Evolution Theory

The theory of evolution is in total contrast to the creation theory. God is totally excluded from the whole picture and it explains that everything from the living to the inert matter originated naturally from gradual changes over millions of years. In other words there is an outright exclusion of the metaphysical or the supernatural realms of existence and everything is described in terms of natural evolution and as a pure chance factor. So man is not a special being but only a natural evolution product from the primitive beings. The one drawback however in this evolutionary theory of existence is that it does not offer explanation as to how the original material which is supposed to have undergone all this transmutation, transformation and gradual evolution came into existence. That is to say that the evolution theory may explain that the tree came from the seed and the bird came from the egg but has no clue for the existence of the seed or the egg. Something is assumed to be in existence before everything else and in this aspect this theory is found wanting in a basic aspect. [H.P. Blavatsky]

Theory of Creationism

This is directly in contradiction to the evolution theory and ascribes every species and every element of creation to have been directly created by god instantly (6 days). That is to say that there is no macro evolution but god created everything that exists during the six days. (though not necessarily 24-hour day) The entire cosmos with all its magnificence from the primitive bacteria to the final crown jewel of creation (man) is a direct creative work of god. The creationist theory is challenged by evolutionary scientists who claim the close relationship between species as a proof of evolution. Further modern astronomy has estimated the age of earth to be some millions of years older than the earliest civilizations on earth hence disputing the theory that all this creation evolved within the short frame of time as described in the bible. Branching out from the pure creationist theory are the deistic and theistic evolution theories.… [read more]


Agreement Between William Harris Research Paper

… It is clear to see how intelligent design theory coincides with the view of the author, who believes that a divinity was responsible for man's creation. Such a theory is largely disrepute by Dawkins in his text. Instead, Dawkins believes that evolution was responsible for mankind, combining various elements of chance and necessity, the latter of which is an integral component in evolutionary theory. The principle difference between Dawkins' conceptions and those of theology is that there is no intelligence responsible in the forces that created man, that instead these forces are mere physics and natural selection, which operated in a "blind" sense and in which their effects are not predetermined or designed (Dawkins 310), but merely combinations of chance and nature. Therefore, Dawkins believe there is no intention or intelligence associated with man's creation -- which is incongruous with the viewpoint of the author.

Kitcher's writing discusses some of the reasons why the author does not agree with evolutionary theory and Dawkins' viewpoint. The principle reason that creationist's disparage evolutionary theory is for the fact that it actually is not a science -- it is a mere theory (Kitcher 323). The lengths of time that it takes to demonstrate the validity of this theory are too long for it to be proven in any individual person's life time. Kitcher spends the duration of this article delineating the fact that creationists' are wrong to look for some sort of perfection in science, which still does very little to champion the cause of evolutionary theory. The whole aspect of evolutionary theory that the author disagrees with, and which is alluded to in Kitcher's work, is the fact that logic and reason -- especially that posited by man, a fallible creature at best -- can discern the causes of all things, including his creation.

In summarizing the author's viewpoint as related to the aforementioned arguments propounded by these various authors, it should be made clear that the author is not a creationist. Harris and Calvert's work proves that there can be a medium between science and faith alone. Their ideas about the nature of design, however, certainly make sense. Perfection cannot be merely stumbled upon. The human mind, especially when it is paired in conjunction with a healthy body and a willing, cognizant spirit, can perform acts of teleportation, time travel, telekinesis, telepathy -- and a host of other things that neither creationists nor evolutionary theorists validate or believe. The author, however, is no less convinced of these facts than he is that this capacity was bestowed upon man by a superior being for reasons that he (mankind that is) has yet to fathom with his current utilization of…… [read more]


Ted Talks Ideas Worth Spreading Essay

Bonnie Bassler: How bacteria "talk" (TED2009, 2009)

Bonnie Bassler gives an overview of the "boring" life that bacteria lead. Basically, a bacterium just grows and divides and then grows and divides again; a simple and steady process that most people would find rather dull. However, Bassler makes this topic far more interesting by relating the life of bacteria to the human body. Most interestingly, the DNA content in the bacteria that is on or in an average human body could be significantly greater than actual human DNA by a factor of one hundred to one. Thus bacteria are essential to human health in multitude of roles ranging from protection to food digestion.

Figure 3 - Bacterial Cells vs. Human Cells and Bacterial DNA vs. Human DNA

Bassler moves to talk about bioluminescence. She speaks about her research in which she realized that a bacterium that is able to produce light does not when it is in isolation. However, when these bacteria are combined in larger numbers, when the number reaches a point all of the bacteria begin to emit light at the same time. Thus the research question emerged regarding exactly how these bacteria can communicate with each other to make this phenomenon happen. Researchers realized that such behaviors were limited to light production and bacteria have a whole range of communication systems for different purposes.

The most interesting aspect of this lecture is that it points out the possibilities for future research and the next generation of antibiotics. Researchers are able to manipulate those bacteria in a way that shuts off their ability to communicate through their cell membranes. Furthermore, not only can bacteria be manipulated to be able to fight drug resistant strands, but the bacteria that are also in our bodies in a symbiotic role can have their signals amplified which could expand their effectiveness in certain roles. Since our bodies are so dependent on bacteria, this opens up a world of future possibilities.

Susan Savage-Rumbaugh: The gentle genius of bonobos (TED2004, April)

Susan Savage-Rumbaugh works with bonobos and refers them as the happiest species on the planet but does not get the coverage they deserve in the news. The reason she states that bonobos have sexual relations that are similar to humans. She makes the claims that the human species is not as special as most people would care to think. Savage-Rumbaugh compares the behaviors of certain indigent tribes to the behaviors of the bonobo and does not see many stark differences in the communities in regards to language and lifestyles.

Wild bonobos often walk upright; sometimes for long distances. The physical frames of the bonobos are not unlike many human ancestors such as the Australopithecus. A video is shown that shows bonobos learning very quickly and that they have advanced communication abilities.… [read more]


Liberalism and Conservatism in Contemporary Education Essay

… Liberalism and Conservatism in Contemporary Education

As with all beliefs, there is not one single way to define liberalism and conservatism, and, while at seemingly polar opposites on some things, they are in complete agreement on others. In general, the two views can be traced by to John Locke and Thomas Hobbes. Locke believed humans were born good, and through actualization of their minds could achieve great things for society. Hobbes believed humans were born flawed, and required strict control in order to behave properly. Locke pushed human views to the future with optimism, Hobbes to the past with what worked before. In policy, Conservatives tend to believe that traditional moral values and a strong national defense, coupled with personal responsibility, free markets, and individualism make an organization strong. Liberals emphasize the need for government to act on behalf of the people, with the protection of civil and human rights being the duty of the State to attempt to alleviate. For educators, a seminal difference is that conservatives tend to believe that it is up to the individual to be successful or not -- they know, in fact, not everyone has the same gifts, and assume there will be a hierarchy of sorts. Liberals tend to believe that everyone needs the same quality education, regardless of ability, and the government should step in and do all it can to help everyone improve their lives (See (Zafirovski, 2008).

The Dilemma of Darwinism - The National Science Teachers Association (NSTA) strongly supports the idea that evolution is a major concept in science education and a major unifying theory. To not teach evolution will mean that students are deficient and unable to achieve the basic level of needed scientific education. Further, the NSTA opposes Districts in which teachers are required to include non-scientific theory into the normal classroom format. For contemporary educators, the debate intensified in the late-1960s, with a shift in the higher Courts' views on more controversial subjects (National Science Association, 2010). In 1968 the Supreme Court rule that States may not ban the teaching of an evolutionary theory (Epperson v Arkansas), then again in 1987 with Edwards v. Aguillard, a Louisiana law making it a requirement to teach creationism as set scientific theory alongside evolution (Edwards v Aguillard, 1987, (Epperson v Arkansas, 1968). While the Courts seem to favor the separation of Church and State, there have been a number of challenges to the foundations of teaching science without using Darwinist theory. Current Justices debate the issue in the scholarly press, the media and scholarly press abound, and the conservative bloc is rife to change the curicculum in favor of their views. For an educator, this is a seminal topic, one that could have, depending on the direction of the Court, extreme rammifactions…… [read more]


Kluge by Gary Marcus Book Report

… ¶ … Kluge by Gary Marcus

In spite of the fact that scientists, and people in general, believe the human mind to represent what is the closest to perfection, it appears that, according to Gary Marcus's book "Kluge: The Haphazard Evolution of the Human Mind," matters are quite different. Throughout the history of evolution, nature has struggled to refine the human brain through various methods, bringing it to its present stage. The general public prefers to believe that humans and their achievements are proof that the human mind is on the verge of reaching perfection. However, as Marcus pictures it, the brain is a result of a series of accidents which happened across time and it is not as perfect as some might actually think.

Evolution has made it possible for the civilized world to exist and has lead to the creation of remarkable technologies. However, as clever as the human mind can be, it is also capable of performing great errors. Humanity has become an expert in improvising with whatever materials it came across. Marcus has even attributed a name to such improvisations, and, Kluge is the term.

Improvisations are not only performed by amateurs, as even scientists can resort to using cobbled together devices when the situation demands it. This is best proved through Marcus's example of the astronauts on Apollo 13, who worked together in making a filter to reduce the alarming levels of carbon dioxide on board the ship. The filter that they made consisted out of several simple materials on board, such as a sock, a bag, and some adhesive tape. Marcus calls the resulted device a Kluge. He claims that the human brain is somewhat similar to the improvised mechanism used by the people aboard the Apollo 13.

History influenced people in believing that the brain is a grand design which has most probably been predestined.…… [read more]

Nineteenth Century American Life Essay

… Charles Darwin

This year marked the 200th birthday of Charles Darwin, and hundreds of special activities were held around the world to commemorate the occasion. Although it has been 150 years since the concept of evolution and the publication of Origin of Species, controversy continues about this theory, especially in the realm of religious belief. Numerous people instead believe in what is called creationism rather than in evolutionary theory. Based on a couple of the newspaper articles from the 1880s when Darwin first wrote his book, it appears that this distinction between those who believe in evolution or those who believe in what is now called intelligent design, is much more an issue today than it was during Darwin's time. During the Victorian time, most leaders recognized that Darwin never said that evolution explained all of life development; there were still unknowns that could be attributed to a higher authority.

According to a study conducted this year, about 50% of the over 2,000 British adults questioned about evolution were either very against the theory or confused regarding it. At least 22% were more in favor of the concepts of creationism or intelligent design to explain the world's origins (Butt). A quarter of Britons say that Darwin's theory of evolution is "definitely true" and the same number says it is "probably true." Ten percent of individuals elected young Earth creationism, or the idea that the world was created by sometime during the previous 10,000 years, over evolution. Just over the same amount supported intelligent design, or the belief that evolution by itself does not provide an explanation about the structures of living organisms. Everyone else was confused, frequently getting creationism, intelligent design and evolution, mixed up.

This debate pro-or con evolution has been a major part of American history since the Scopes "Monkey Trial" in the 1920s, when a high school biology teacher was charged for covering evolution in his science curriculum. Clarence Darrow was the teacher's attorney, and William Jennings Bryan, who had run as the populist Democratic presidential candidate three times, supported the State of Tennessee. The anti-evolution movement won the case, and it took until 1967 for the law to be removed from the state's books. In a number of other states, today, creationism is very strong. In Kentucky, a creation museum just opened up a couple of years ago and has exhibits of humans and dinosaurs living together.

When reading a couple of articles from the late 1800s, it is interesting to see that there was not this black-or-white situation. People, including some clergy, recognized that Darwin was not saying it was either evolution or belief in God. He was instead arguing that evolution was one of the ways that explain living organisms. In an article from the English Church Quarterly, the writer demonstrates the reasons for the "triumph" of Darwin's ideas and "fearlessly argues in favor of the compatibility of the Darwinian theory with religious belief." He further states that Darwin never claimed that natural selection… [read more]


Anthropology - Bipedalism: Evolutionary Significance Term Paper

… Anthropology - Bipedalism

BIPEDALISM: EVOLUTIONARY SIGNIFICANCE and CONSEQUENCES Introduction:

Traditional anthropological theory emphasized the relative size of the human brain, as measured by cranial volume and capacity, as the primary evolutionary adaptation that accounts for the profound difference between homo sapiens and other hominid species. Recent studies contradict this conclusion and suggest that bipedalism was the most significant evolutionary adaptation rather than cranial capacity, and that the former may actually have played at least an equal role in the evolution of human intelligence.

As a student of anthropology, I was fascinated by this revelation in three different levels: first, it represents a dramatic shift in our understanding of an area of human evolution that is described in contemporary textbooks as established fact; second, it suggests that many other conclusions in the field may be less certain than I had previously considered them to be by virtue of their inclusion in academic texts; and finally, it highlights the fascinating trade-off, in principle, between long-term evolutionary benefits of particular adaptations and the negative short-term consequences in terms of the lives of the individual.

Behavior-Driven Adaptation:

Bipedalism in humans is one example of an anatomical evolutionary transition resulting as a consequence of behavior, rather then the reverse. It is believed that early hominids began standing upright and walking on two legs instead of four first, and that this behavior triggered a very gradual evolutionary adaptation of bipedalism to take advantage of the profound benefits of the behavior. Specifically, bipedalism is a much more mechanically efficient mode of locomotion compared to quadruped locomotion. It conserves significant amounts of energy, primarily through recapturing as much as 65% of the kinetic energy required to swing the legs by virtue of the upside-down pendulum motion that accurately describes the act of walking in engineering terms.

Since bipedal locomotion requires a more efficient cooling system to maintain a physiologically optimal internal temperature, this single adaptation is thought to have triggered many others, including the evolution of sweat glands, the disappearance of significant body hair, and numerous anatomical structures that distinguish modern human anatomy from all of our simian relatives. For example, only humans have flexible tendons, complex shock-absorbent heel bones, and comparatively straight legs, all of which are considered to have been directly related to the natural transition from bipedal walking to running. In fact, running on two legs is much faster and more efficient than the fastest sustained quadruped…… [read more]


Charles Darwin the Descent of Man Term Paper

… Descent of Man

Since their earliest history, humans have been intrigued with their origins. Prehistoric cultures developed creation myths that tell of a separate creation of man and of the domination of man over the rest of the animal world. The Roman statesman Cicero wrote of gods, universe and the creation of life on earth for humans. It was not until the late 1700s and early 1800s that human development was studied from a scientific perspective, especially by Jean-Baptiste Chevalier de Lamarck. However, it was Charles Darwin who revolutionized thought about evolution, first with the book Origin of Species and, more closely connected with humans, the Descent of Man and Selection in Relation to Sex. This second book, published in 1871, specifically looked at how humans evolved from the same ancestors as apes in terms of society and morality. It completely altered the concept of human nature and started a controversial debate that continues to this day.

According to the biography the Life of a Tormented Evolutionist: Darwin (1991), Charles Robert Darwin was born and raised in Shrewsbury, England, in a family that was already interested in the sciences. His grandfather Erasmus Darwin, a physician and scientist, theorized the first ideas on evolution, and his father was also doctor. Although Darwin started medical school, he and his family both realized that this was not the field for him. He went instead to ministry school and began to learn about zoology and geography and became very interested in the topic. It was in 1831, however, that his life completely changed. He was asked to share the captain's responsibility aboard the ship H.M.S. Beagle, which was taking a two-year survey of the coast of South America.

It was on this voyage that Darwin first conceived of the theory of evolution. He said in his first book Origin of Species (1859): "When on board H.M.S. Beagle as naturalist, I was much struck with certain facts in the distribution of the organic beings inhabiting South America, and in the geological relations of the present to the past inhabitants of that continent." He conceived that life, evolves by a process called "natural selection," or the process where favorable genetic traits become more common in successive…… [read more]

Trial Term Paper

… ¶ … Trial

In the start of the current century we find a new way of thinking called 'intelligent design' the summer of 2005 saw President of United States endorsing this new idea which others call a euphemism for creationism. Public opinion also seemed to be heavily divided on the issue showing that a majority of Americans today reject Darwin's theory of evolution. All this debate in the current century reminds us of the famous Scopes Trial almost 80 years ago.

Even though the famous trial settled a burning issue and many considered it a triumph of science but the echoes of debate in fact never ceased in the years the ensued after the trial till date. Many events tried to capture the trial and its essence in different events like a 1960 movie 'Inherit the Wind'. "As an icon of the triumph of science over religion, the Scopes trial would enter into the American imagination primarily through the trenchant, if selective, cynicism of that proto-curmudgeon, H.L. Mencken, who covered the trial for the Baltimore Sun, and later through the gross distortions of historical reality in Inherit the Wind, the 1955 play by Jerome Lawrence and Robert Edwin Lee, which became a hit film in 1960" (Gaffney Jr., 1998).

The decade of 1920s can be considered a decade when a clash of cultural ideas took place and revivalism took roots in society. Intellectual experimentation prospered as young and the old and traditionalist and modernists started confronting each other on many issues. 18th Amendment was passed and people started looking at prohibition as a curb on their freedom. The debates on topics ranging from art to Freudian theories finally became a battle of tradition and modernism in the famous Scopes Trial which debated on the evolution theory in a Dayton, Tennessee courtroom in the summer of 1925.

When Darwin proposed his theory of evolution, it met fierce opposition and criticism but with time the theory became acceptable in academic circles. Still, many opposed the teaching of the theory in high schools of the country. Places like Tennessee, Oklahoma, and Mississippi even passed laws forbidding the topic of theory of evolution in the curriculum. John T. Scopes at Central High School in Dayton became the center of all debate when as a part of a movement to challenge such laws supported by American Civil Liberties Union got arrested on charges of going against the laws.

The lawyers that fought the case became famous names for fighting for the two diametrically opposite views. Clarence Darrow was one lawyer who was famous for his anti-evolution views and thrice-failed Democratic presidential candidate and former Secretary of State William Jennings Bryan was another one.

Since this trial debated a hot issue, it attracted a lot of attention of the people from all…… [read more]

Darwin and Lamarck Term Paper

… Darwin vs. Lamarck

To begin with a brief overview of the scientists, let's begin by considering Mr. Darwin. According to Wikipedia (2005), after years of studying a variety of organisms, Charles Darwin, in 1859, wrote The Origin of Species. This was a very popular book, which held the famous and widely-studied Darwinian theory known as "survival of the fittest." The initial printing sold out on the first day of publication, but Darwin's theory eventually lost some of its original popularity. Although many field naturalists preserved Darwin's emphasis on the role of geographical factors on evolution, many were later tempted by the theory of Lamarckism, which has stemmed much discussion on the Darwin vs. Lamarck controversy. Lamarckism is a theory named after Jean Baptist de Lamarck, who was a French naturalist that published Zoological Philosophy in 1809 (Wikipedia 2005). In his view, organic beings constituted a ladder of life from simplest to complex animals, with humans at the top rung. Lamarck did little in the way of explaining the origin of this ladder, but he did offer an explanation for how organisms change over time, thus turning the ladder into what we might call an escalator of being.

It is important to examine the differences between scientific theories, as scientists and science educators are in agreement as to the importance of an understanding of evolutionary principles as the unifying theme for acquisition and internalization of information about the origin, history, and diversity of life on earth. However, despite this agreement, evidence from various sources suggests that indicates that many students leave their courses still significantly confused with the differences between various theories. According to Richard Firenze (1997), "It appears these misconceptions can be divided into two major categories: 1) epistemological misconceptions - those dealing with the nature of science, that is, evolution is only a theory, evolution has never been…… [read more]

Heritable Variation in a Population Term Paper

… Those who did not develop these variations tended to be "less fit" in the "survival of the fittest," and thus they were less likely to mate and ultimately pass down their weakness in the given environment. Those who were lucky enough to have this variation in their genetic makeup were more likely to survive and pass on their strength to the next generation through heritable variation.

As the environments of the planet are not fixed it is incredibly important that a population's genetic makeup is not fixed either. Variations within a population's makeup allow the population to adapt to their ever changing environment. Without a constant flux in variations between generations many species would have a very difficult time maintaining their population's survival in an ecosystem that thrives on variation.

Variations within any species are incredibly important. Without heritable variations many species would lose their ability to evolve. Variation and natural selection are the basis for evolution as it is understood today.

Evolution of Man Term Paper

… 6 and 2.3 million years ago. Their brain size was very small some parts of the skull resemble the ones of Australopithecus afarensis (Anonymous, PG).

Followed by Australopithecus boisei (sometimes known as Zinjanthropus boisei) dated to around 1.75 mya, A. boisei was also a heavily built australopithecine, was in all likely hood a vegetarian, and possessed thick jaws with large black teeth, it seems that boisei and robustus were related to that of africanus as they are very much alike apart from africanus being more gracile (McKie, 46).

Looking at the second branch of the phylogeny there is Homo Habilis (Handy Man or Person) dated to around 2 mya features larger brains, was more gracile than the Australopithecines, faces were more delicate and less prognathous, smaller jaws with less specialized teeth (Fagan, 49)

These are followed by Homo erectus dated to around 1.9 mya to 40, 000 ya the brain size increased. H. erectus had a larger skeleton overall and was much like modern humans as compared to the Australopithecines. He was powerfully built had massive brow ridges and a large face which had a long skull.

It is again here that the phylogeny tree diverges into two, on one side there is the branch that many scholars argue is either a dead end branch (Stringer and Gamble) or is a continuation of the normal branch. For the purpose of this study I have placed Homo neanderthalensis as a dead end branch.

The other path of the tree consists of early Archaic Homo Sapiens and Homo Sapiens (Modern man), from this simple sequence of how man evolved from the earliest hominid Ardipithecus ramidus to the Anatomically modern Human we can see there has been a slow and also quick succession in human abilities and structural changes in the skeletal frame. These changes are the evolutionary changes that have evolved to make modern man what he is today.
