The thought of evolution is filled with theories, ideas and beliefs. The definition of evolution is rather simple. According to Jerry A. Coyle, evolution is “the change in the inherited characteristics of biological populations over successive generations (2). Evolution gives rise to diversity when it comes to the hierarchy of life otherwise known as biological organization. Many people find the topic of evolution to be troubling and very confusing. Throughout history churches have preached that evolution is atheistic and a sin if even thought about. Famous scientist, Charles Darwin, is said to really be the first to formulate debated theory of evolution by the means of natural selection. Eventually in the 20th century genetics was compounded with Charles Darwin’s theories of evolution. Even today scientists continue to study different aspects of the theory of evolution.
There is a long line of history surrounding evolution. Theories really stated with creationism. According to Donald R. Prothero, leading paleontologist, creationism is the belief that living organisms in the unive...
What is evolution? Evolution in modern terms is fairly easy to understand. Evolution is the theory that life on earth began with a single celled organism that lived more that 3.5 billion years ago that slowly evolved into many diverse creatures over time. When you break down this theory into sections you get 6 factors: evolution, gradualism, speciation, common ancestry, natural selection and nonselective mechanisms of evolutionary change.
Keith Henson a writer in evolutionary psychology once said that “Evolution acts slowly. Our psychological characteristics today are those that promoted reproductive success in the ancestral environment.” Evolution was first introduced by a naturalist by the name of Charles Darwin. Darwin had written an autobiography, at the age of 50, On the Origin of Species (1859) explaining how species evolve through time by natural selection; this theory became known as Darwinism. “Verlyn Klinkenborg, who writes editorials and vignettes on science and nature for the “New York Times”” (Muller 706) questions Darwin’s theory in one of his essays he wrote called Darwin at 200: The Ongoing Force of His Unconventional Idea. Both articles talk about the theory of Darwinism, but the authors’ use different writing techniques and were written in different time periods. Darwin himself writes to inform us on what the theory is, where as Klinkenborg goes on to explain why Darwinism is just a theory. Today, evolution is still a very controversial topic among many. It comes up in several topics that are discussed everyday such as in politics, religion and education.
The theory of origin of species by Darwin came out in 1859, and how our world really began has been a controversial topic throughout time. Darwin hypothesized that all species originated from one or more original beings. For example, Darwin claimed humans have evolved from apes. This theory challenged the prevailing view at that time, and was questioned by the fields of science and religion. Nevertheless, in the 156 years after the theory was published, the debate continues on how the world has been created. People from different fields tried to use scientific, biblical and theoretical evidence to prove their viewpoint. Based on different viewpoints, people have provided different reasons for the origin of life.
What is a scientific theory? How does the scientific use of theory differ from common uses of the word theory? What effect does this have on public discussion about Darwinian Evolution?
In the history of science vs. religion there have been no issues more intensely debated than evolution vs. creationism. The issue is passionately debated since the majority of evidence is in favor of evolution, but the creation point of view can never be proved wrong because of religious belief. Human creation breaks down into three simple beliefs; creation theory, naturalistic evolution theory, and theistic evolution theory. The complexities of all three sides create a dilemma for what theory to support among all people, religious and non-religious.
Talking on both sides of the debate, each side feels as though the other has no scientific reasoning come up with their theory. In reading the article written by Shipman, the evolutionists believe that intelligent design has no concrete evidence on how the world was crea...
Have you ever sat down and wondered where the heck did we come from? Well if you did this is the paper for you. In this paper the amazing Darshan Aidasani will be explaining everything about evolution, so sit down, relax, and get a bowl of popcorn because this is going to be interesting. What is evolution? Evolution is the process that all living things developed from primitive organisms over billions of years ago. Up to this day know one knows exactly how evolution occurs, but there are many theories. Including, the Carolus Linnaeus theory, the Erasmus Darwin theory, the Jean-Baptiste Lamarck theory, and last but certainly not least the Charles Darwin theory. Many people are skeptic which mean they think that evolution is fake and don’t want to even hear the facts behind it, these people usually believe in creationism. In this essay I will be doing an over view of evolution.
What is evolution and how does it work? Evolution is the theory of how one form of life changes into another form. Evolution also is the change in a population’s inherited traits from generation to generation. Evolution helps to explain why an animal, human, and plant looks the way it does and acts the way it does; it gives an explanation of the history of life. Genes come in many varieties, and the evolution helps to make it happen.
Evolution views life to be a process by which organisms diversified from earlier forms, whereas creation illustrates that life was created by a supernatural being. Creation and evolution both agree on the existence of microevolution and the resemblance of apes and humans but vary in terms of interpreting the origins of the life from a historical standpoint. A concept known as Faith Vs Fact comprehensively summarizes the tone of this debate, which leads to the question of how life began. While creation represents a religious understanding of life, evolution acknowledges a scientific interpretation of the origins of life. The theory is illustrated as the process by which organisms change species over time.

The evolution theory, one of the most significant theories, laid groundwork for the study of modern biological science. This theory has lead scientists into unending debates due to lack of empirical supports. Until the mid-eighteenth century, when Charles Darwin came up with an explanation to evolution, scientists, then, began to endorse this hypothesis. In “Natural Selection,” Darwin explains the natural selection, a plausible mechanism that causes evolution, to gain approval of his cynical audience for his evolution theory. He supports his claim with numerous examples of animals and plants that have developed traits beneficial for survival. A century later, Stephen Jay Gould, influenced by Darwin’s work, supports the evolution theory with a different method. In “Evolution as Fact and Theory,” Gould, in contrast to Darwin, criticizes his detractors, the creationists who believe that every life form is the creation of a supernatural being, to reinforce the validity of the evolution theory. Gould undermines creationism by emphasizing its misused concepts of theory and popular philosophy, proving that it is not science. Besides denouncing creationism, Gould also provides theoretical examples as evidence to prove evolution is a theory. Despite their different approaches, both Darwin and Gould effectively prove the existence of evolution.
Evolution has become a controversial topic over the years and with dominant evidence, we know that it takes place even today. Evolution is a slow and time consuming process which is why we do not observe it instantaneously. To observe evolutionary patterns, you must take it in large amounts of time. Charles Darwin is known as the “Father of Evolution” and discovered much of the evolutionary concepts that we have an understanding. Evolution has branches that include change with humans, animals, sex, behaviors, survival, and extinction. Summed up, evolution is a scientific theory that states that change over time in the biotic population. The controversy of evolution has always come from opposing religious viewpoints of creationism. Natural Selection
One of the greatest questions of all time is: "Where the heck did we come from?" One of the most popular answers to this question is creationism, the idea that everything was created by a higher being. Another idea is evolution, the idea that all living organisms descended from a less complex organism. Up and coming in the last century, evolution possesses a new way of thinking that is being greatly accepted by the scientific community. Despite this fact many people argue that evolution has no facts to support it and there are several reasons why evolution can't happen.
Without evolution, and the constant ever changing environment, the complexity of living organisms would not be as it is. Evolution is defined as a process that results in heritable changes in a population spread over many generations (8).Scientists believe in the theory of evolution. This belief is based on scientific evidence that corroborates the theory of evolution. In Figure 1 the pictures of the skulls depict the sequence of the evolution of Homo-sapiens. As the figure shows, man has evolved from our common ancestor that is shared by homo-sapiens. The change of diet of homo-sapiens over time has thought to contribute to the change in jaw structure and overall skull shape.
