In this lab report it will evaluate a modern-day understanding of evolution using a link to analyze some data. The evolution website link will use numerical data to develop parameters that may influence a natural selection for researching and formulating a hypothesis. The data describes the results on Wallace Island and Darwin Island, testing one of the population mean, creating original parameters, and reproduction evolution. The formulating process uses both verbal and numerical hypothesis using the five-step hypothesis test on information pertaining to the selection per island. Finally, the outcome of the test will explain the how each result from this hypothesis testing is answer for Darwin Island and Wallace Island. The diversity and capacity of influence on the beak size and inhabitants number available data obligated to center on a matter discuss daily. A scientific theory necessitates that each theory be analysis under various conditions and meticulously. Any theory that continues to exist testing and may have led to a rejection is a well-built theory. Sometimes scientific evolution consists of classifying the circumstances under which a theory fails or holds like the size of beaks will influence inhabitant’s statistics. The beak size affects the diversity of the living organisms in a population with multiple numbers. After looking at the statistics over time the two islands speculates what may happen to beak sizes on Wallace Island and Darwin Island. The inhabitants of the finches on Darwin Island were significantly superior for the first two hundred years. In an attempt to narrow down the beak sizes, the report will focus more on Darwin Island even though the beak sizes were significantly diverse. The oral or verbal theory is equal to Wallace Island and the numerical theory is 20 millimeters to…...

...The theory of evolution, formalized by Charles Darwin, is as much theory as is the theory of gravity, or the theory of relativity. Unlike theories of physics, biological theories, and especially evolution, have been argued long and hard in socio-political arenas. Even today, evolution is not often taught in primary schools. However, evolution is the binding force of all biological research. It is the unifying theme. In paleontology, evolution gives workers a powerful way to organize the remains of past life and better understand the one history of life. The history of thought about evolution in general and paleontological contributions specifically are often useful to the workers of today. Science, like any iterative process, draws heavily from its history. It is a FACT that the earth with liquid water, is more than 3.6 billion years old. It is a FACT that cellular life has been around for at least half of that period and that organized multicellular life is at least 800 million years old. It is a FACT that major life forms now on earth were not at all represented in the past. There were no birds or mammals 250 million years ago. It is a FACT that major life forms of the past are no longer living. There used to be dinosaurs and Pithecanthropus, and there are none now. It is a FACT that all living forms come from previous living forms. Therefore, all present forms of life arose from ancestral forms that were different. Birds arose from nonbirds and humans from nonhumans. No......

...Evolution Lab BIO/101 Pooja Thakur 7-23-12 Evolution Resulting From Natural Selection INTRODUCTION The Evolution Lab simulates environmental situations to determine effects on evolution over periods of time. This lab experiments with the evolution of finches on two different islands over 100, 200, and 300 years. By manipulating parameters that influence natural selection, the effects that natural selection have on the evolution process can be studied. HYPOTHESES • The size of the island will influence the population. • The amount of precipitation will influence beak size. • Variances in beak size will influence beak size. MATERIALS The materials needed for this experiment consist of a computer and access to the Evolution Lab on the University of Phoenix student website. In the Evolution Lab there are two islands, Darwin Island and Wallace Island. There are seven variables that can be changed to run many different experiments on both islands. The variables are beak size, variance of beak size, heritability, clutch size, island size, population, and precipitation. METHODS In all of the experiments Darwin Island was used as the control group and Wallace Island was the experimental group. So, in each test, the variables for Wallace Island were altered and the variables for Darwin Island were left alone. The first experiment was to determine whether or not the size of the island affected the population. To do this, the only variable......

...Search for Evolutionary Proof Arjumand Parham Sci 115 7/24/12 Dr. Freeman Search for Evolutionary Proof “Our ability to grasp, to build, and make out thoughts real lie inside this complex system of bones, nerves and vessels.” –Neil Shubin These things would only be possible through evolution. Evolution is any process of formation or growth and development, without it we wouldn’t be here today. Evolution though only an theory has an massive backing within the science community; many fossils, scientist and scientific studies have all but proved evolution indefinitely. The proof for evolution is massive and profound; fossils and carbon dating are absolute proof that creatures very similar to us not only lived but were evolving and walking around. African hominids such as the bipedal Australopithecus afarensis or “Lucy” are some of the most profound examples of evolutionary history. Unlike a common monkey Lucy was a bipedal specimen which meant she walked upright much like an human. What makes her such an amazing discovery is the fact that she was about three-million to almost four-million years old. Scientist from every side of the spectrum have gathered to try to make this theory fact. Neil Shubin paleontologist and archeologist said” We were not designed rationally, but are products of a convoluted history”. The history of the human body is convoluted in every sense of the word; there are approximately three-billion-five-hundred-million years of history in the......

...The beginning of the earth has been a mystery, boggling the minds of the erudite and the simple minded alike for years. The topic of creation vs. evolution has become increasingly controversial. In biology, Darwin’s Theory of Evolution is a change in the genetic material of a population of organisms from one generation to the next. Though changes produced in any one generation are normally small, differences accumulate with each generation and can, over time, become substantial changes in the population. Such similarities among species suggest that all known species are descended from a common ancestor (or ancestral gene pools process of gradual divergence). Evolution is supported in many different ways, but one major category pointing to its validity is fossils. Through fossil dating, hominoid fossils, and, evolution has become the theory accepted by the majority of those in the scientific forefront. Evolution is supported through fossil records. The study of the sequence of occurrence in rocks reveals the relative time in which organisms lived. This technique shows that one layer of rock is older or younger than another. Later through the discovery of radioactivity, scientists were given the opportunity to learn the age of fossils and rocks . Through these records, a vague timeline is illustrated of the evolutionary change that has been occurring over the past four billion years. This proves that the earth is much older then creationist would like to argue. A popular......

...The Evolution of Finches on Darwin and Wallace Islands Angela Vaughn BIO/110 December 9, 2013 Heather Browning The Evolution of Finches on Darwin and Wallace Islands In the 1800s, Charles Darwin, a brilliant scientist and naturalist, observed that an organism’s traits allowed it to adapt to an environment. These organisms would produce offspring that possessed abilities to survive in their environment. Those that did not possess these traits were less fit and were unable to survive the environment. This was the beginning of the study of evolution and natural selection. “Evolution is the study of how modern organisms have descended from the earliest life-forms and of the genetic, structural, and functional modifications of a population that occur from generation to generation. The ability of a population of organisms to respond to change in their environment and survive and reproduce by developing the characteristics or modifications necessary for survival is known as adaptation.” (University of Phoenix, 2013) House Finches live in dry desert, grasslands, stream sides and open coniferous forests at elevations below 6,000 feet. They eat seeds, buds and fruits. (House Finch, n.d.) The purpose of the experiment is to test my hypothesis, “Precipitation does not cause natural selection to act upon beak size.” Materials To complete the experiment, I will need access to a computer and the Evolution Lab simulation at the University of Phoenix website.

...Evolution within the field of Physical Anthropology is the Idea that “species change over time and have a common ancestry”(Park 2009, p36). With this in mind, the field of Physical Anthropology, also known as Biological Anthropology, can be used to explore and investigate the evidence of the human evolution. Within Biological Anthropology, evolution is observed as the change of humans and human ancestors over time. These changes that occur do not take place over night, nor do they happen over a decade. It takes thousands of years to produce changes in an organism to the effect that it would be classified as evolution. Physical Anthropologists study the remains of Hominins and other ancestors of humans to discover the link that connects us all. They also study other creatures to compare them to humans in an effort to understand where humans come from and what makes us human (Gonder, 2013). One way that Physical Anthropologists have found links of evolution from early Humans and Neanderthals is through dental evidence found and investigated by Professor Alan Mann. He concluded that modern humans did in fact evolve from Neanderthals by finding links in the dental history of each species. Though his evidence is disputed by some, like any other scientific evidence, there have been some that support him and have come to the same conclusion of the relationship between Humans and Neanderthals. One piece of evidence that supports his theory is from a group of researchers from......

...Evolution Abstract One paragraph… The discussion on the origin and fate of the universe continues to revolve around creationists and evolutionary ideas, though creationism positions arise mainly of religion and philosophy, while the evolution is postulated mainly from science. One wonders if possible convergence in these fields in the discussion, that is, if you can address both creationism and evolutionism from science, philosophy and religion. Theory of Evolution In science the theory of evolution explains the huge variety of life arising by postulating a process of transformation through changes in genes that lead to new adaptations to the environment. By studying the genetic structure of living beings is a verifiable fact that they are related to each other and, therefore, aims to have a common origin as the emergence of new species due to the accumulation of changes that do diverge and take different paths to adaptation to the environment. In the scientific world, biological evolution represents the interpretative key of the living world. Life began about 3500 makes 4000 million years in the form of single-celled organisms without nuclei and took about two billion years to produce the first eukaryotes (unicellular organisms with nuclei), so the start was given very slowly. However, in evolutionary history there are times with a high evolutionary rate as the Cambrian period (540 to 520 million years, they were many forms of multicellular life). They also......

...being taught in schools. Although we are known as a Christian country, religious ideas in public places are frowned upon or replaced. Now, scientific theories- evolution and the big bang- are being taught as fact to students across the nation. This is a growing problem because evolution is not a fact, only a weak theory based on misinterpreted evidence. There are two types of evolution being taught. One type, also known as natural selection or species adaptation, is when specific changes occur in one species. According to Roger Patterson, author of Evolution Exposed, natural selection is how a species changes, or evolves, in short periods of time. For example, one breed of dog evolved slightly to create the many different breeds of dogs we have now. This makes sense. Why? All dogs are similar to each other. You could say the same for birds, fish, cats, or any other animal. However, the theory of evolution says every living thing on the earth- plants, humans, animals and microscopic organisms- originated from only one organism. This is unrealistic. Natural selection can be tested and observed. On the other hand, the theory of evolution should not be taught as logical, evident factual information because it has not been scientifically proven as most of the non-Christian scientific world would tell you. Along with evolution, a theory for the origin of life, we have the Big Bang Theory, a theory for the origin of our universe. According to Dr. Jason Lisle, author of The......

...Evolution is what has allowed humans beings to become the complex organisms that we are today. This long and interesting process has taken millions of years to occur. There is a significant amount of evidence found in living and non living species that the first human ancestors lived approximately 6 million years ago. There is still a few holes in the theory of evolution that can’t quite be explained yet, but scientist have a pretty clear understanding of where, why and how humans evolved. The family Hominidae or hominids, is defined as including humans and the great apes. Scientists further split up this family into two sub-families, one of which is the hominins, which includes humans and their ancestors since the time of divergence from the common ancestors of humans, chimpanzees, and bonobos. The oldest known human ancestor is A. tchadensis. The first evidence of this species was named Toumai and was found in Chad, Africa. It is believed that A. tchadensis inhabited the part of Africa that we now call Chad about seven to six million years ago. Based on Toumai’s cranial characteristics it is believed that this species was bipedal. Fossils have also been found from a different species in Ethiopia. According to the fossil records this species called A. ramidus lived about 4.4 million years ago and were definitely bipedal. The famous fossil of “Lucy” unveiled yet another species that is a common ancestor of humans called A. afarensis. A. afarensis live approximately 3.3......

It’s what has shaped and define all living organisms on this planet. Evolution has helped all population and organisms respond to change in their habitat. The way they have survived is by passing on certain traits that have worked on keeping them alive it is known as adaptation. I wanted to see what would happen if you changed the eating habits of finches. What effect this will have on the evolution of life on this island? Materials All of the materials that you will need for this experiment are: a computer, pencil, paper for notes, and access to the Evolution Lab on the student website for the University of Phoenix. Introduction First, I went to the student web site and used the Evolution Lab website for the University of Phoenix. What I wanted to do is run two different scenarios to determine how much effect food sources have on finches. The test has seven different variables that you can change and those are beak size, variance, heritability, clutch size, island size, population, and precipitation. The test is simulated on two different islands one is named Darwin’s Island and the other is named Wallace’s Island. Experiments The first experiment that I ran I chose to set my parameters for Darwin’s and Wallace’s island the same. The parameters are: initial beak size 12.0 mm, heritability 0.7, variance 1.0, clutch size 10.0 eggs...

...Online counseling is also filling the unmet need for clients located in areas traditionally under-served by traditional counselors. Rural residents and expats along with under-served minorities often have an easier time finding a suitable therapist online than in their local communities.[2] These access issues are solved with online counseling resources and result in clients receiving culturally or linguistically relevant treatment that they would not have otherwise been able to receive. African Americans tend to have an elevated rate of stress-related diseases and have lower access to traditional face-to-face treatments.[5] Online counseling has also been shown to be effective for clients who may have difficulty reaching appointments during normal business hours. [6] Additionally, research is demonstrating that online counseling may be useful for disabled and rural people that traditionally under-utilize clinical services. [2] Effectiveness Some in the psychology community have argued that online therapy can never replace traditional face-to-face therapy.[7] Research from G.S. Stofle and J. suggests that online counseling would benefit people functioning at a moderately high level.[8][9] Severe situations such as suicidal ideation or a psychotic episode might be better served by traditional face-to-face methods.

...ION * PART A. Examine the mechanisms of evolution. * Evolution is the process by which modern organisms have descended from ancient ancestors (Evolution, N.D.) The four mechanisms that allow evolution to take place are genetic drift, gene flow, mutations, and natural selection. All of these mechanisms happen naturally and are necessary for evolution to take place. Genetic drift is the random change in gene or allele frequency with which an allele variation occurs in a small population. Genetic drift is simple change. Two different genetic drifts that can change the size of a population are the bottleneck effect and the founder effect (Campbell, Reece and Simon, 2004). The bottleneck effect occurs during drastic changes in an alleles population causing the population to have some alleles that may be underrepresented or eliminated completely (Campbell, Reece and Simon, 2004). Chance may affect the alleles population for generations until the population will become large enough to allow sampling errors to be considered insignificant (Campbell, Reece and Simon, 2004). Genetic drift in a new colony is called the founder effect (Campbell, Reece and Simon, 2004). It is likely to occur when a few individuals colonize an isolated area (Campbell, Reece and Simon, 2004). When a colony migrates away from a larger population its gene pool becomes least representative of the larger colony it migrated from (Campbell, Reece and Simon, 2004). Gene flow is the genetic exchange of......

...desirable traits that were once only prevalent in a few individual animals became common traits for entire species (Winston, 2009). There are countless amounts of evidence that suggest that humans owe their existence to evolution, however, many people are skeptical as to whether or not it is still occurring, and whether or not it is happening in the same way. Some scientists hold that the human race has reached “its biological pinnacle and is no longer capable of changing” (McKie, 2005, ¶1). Alternatively, some experts believe that humans are evolving faster than ever (Sample, 2007), and others believe it is still happening, just on different terms. There has not been any deciding evidence as to whether or not humans are still evolving, however, saying it isn’t happening is a very difficult position to defend. Gene mutations happen at random so saying that humans will never undergo any more evolutionary changes seems very unlikely (Douglas, 2006). Many scientists and evolutionists believe that the complexion of modern society is changing the means by which natural selection and, consequentially, evolution is occurring. The evolutionary trait of an advanced brain is what defines us as humans; ironically that same brain is what is allowing us to change the rules of evolution. As a result of a number of medical advancements, doctors are able to sustain life that would not have lasted back in Darwin’s time. This means that humans with genetic advantages are not the only ones......
