...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 Lab Sherrie Hamby BIO/101 January 18, 2012 James Marlowe Evolution Lab Evolution is a necessary stage and part of life. 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...

...Evolution Lab BIO101 December 4, 2012 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...

...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 that...

...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. [10] Although further research may prove otherwise.[2] Cohen and Kerr conducted a study on the effectiveness of online therapy for treatment of anxiety disorders...

...Electronics rely heavily on electronic switching and amplification to generate and capture the various signals which allow them to operate. A controllable valve that allows a small signal to control a much larger signal does this, and could be related to a controllable valve used in the control of water flow. This was once done by a device known as vacuum tube but was later brought down to a much lower production scale for a variety of industrial, economical and business related reasons. Bell Laboratories, the research arm of telecommunications company American Telephone and Telegraph’s (AT&T) director Mervin Kelly put together the first team of researchers and scientists placed on the task of research and development of a solid state-semiconductor later called a transistor that would supersede vacuum tubes and provide numerous advantages. The success of this development would prove to change the computing, electronics and telecommunications systems altogether. Up until the invention of the transistor a vacuum tube was used in the control, amplification and generation of electrical signals. Vacuum tubes are tubes usually made from glass and designed in an airtight manner as to keep the flow of “cathode rays” from external disturbance as they pass from each terminal and laid the foundation for numerous technical innovations, such as the light bulb discovered by Thomas Edison (fig. 1). Joseph John Thomson further made a vacuum tube and placed a third terminal to attain a grasp...

...The Natural Selection Process of Evolution “Darwin Island” and “Wallace Island” finches have survived many years on these isolated islands without much help from the human population. They are able to survive by adapting to their surroundings by a process called evolution. The evolution process begins with a process called natural selection. At this time, both islands are around the same size and the finches have similar populations and beak sizes. What would happen in 200 years if the “Wallace Island” shrank 0.2km and “Darwin Island” grew 0.2km and the clutch sizes for the finches increased by 4 eggs in size? Would the finches still have similar populations and beak sizes? Materials The material used for this experiment was my home computer and the Evolution Lab web link on the University of Phoenix Student Website. Methods and Procedures The first step in my methods and procedures was to login to the University of Phoenix Student Website. Next, I went into the materials link of my classroom and clicked on the web link for the Evolution Lab. Finally, once I am on the Evolution Lab website, I clicked “start lab.” After clicking start, the first step in understanding the natural selection and evolution process was to read the background information. Next, was to run a control experiment to see where the finches on “Darwin Island” and “Wallace Island” would be if nothing out of the ordinary happened. Once the control experiment was completed and the data recorded...

...Kelsey Williams Professor Reiner March 29, 2016 BIOL-108 Island Biogeography Lab Write-Up Purpose of lab: Calculating how many species were migrating to different islands Hypotheses: The main factors are island size and distance from the island. We hypothesized that islands close to a source area should have a higher number of species than islands further from the source area for islands of equivalent areas. Larger islands should have more species than smaller islands for islands located at similar distances from the source area. Data table—compiled with other groups* Table 1: Island Biogeography Lab Data (fill this in) | Close (2m) | Middle (3m) | Far (4m) | Small (0.25 m2) | 1 | 3 | NA | Medium (.5m2) | 10 | 10 | 6 | Large (1.0 m2) | 15 | 16 | 16 | Graph for ONE simulation—for YOUR GROUPDATA---include title, label axes, write legend (i.e.-medium island at 3M supports 12 species) Legend: The linear trend lines did not intersect.

After all the data was collected, the results showed 2 homozygous dominant, 3 heterozygous, and 32 homozygous recessive. Lab sections D, G, E1, and E2 all experienced problems during the lab causing the data to be skewed and no results were collected. Figure 3 shows the calculated allele frequencies, chi square analysis, and Hearty Weinberg done for the Alu data collected during lab. In order to calculate the observed frequency, the amount of a genotype (+/+, +/-, or -/-) is divided by the total amount of all genotypes collected in lab.
