The Future of Tracking Devices

the incessant brutality of racism in the 1920s. Rolf de Heer’s 2002 art house feature film The Tracker, represents one of the most “unspeakable aspects of Australian history” (Smaill, 2002, 31), explicitly depicting the extreme racism, violence and inhumanity the egotistical European invaders inflicted on Aboriginals, whilst at the same time glorifies and treasures aboriginal culture and intelligence through film.

The different perspectives create interest and draw us into the experiences of others. The two texts, ‘The Tracker’ composed by Rolf De Heer and ‘Bran Nue Dae’ composed by Rachel Perkins explores this notion. Both films are evident to the racial discrimination of Aborigines in Australia. ‘The Tracker’ is a 2002 art house film set in 1922. It is clear that there were no Aboriginal rights and which white settlement had the greatest control. ‘Bran Nue Dae’ is a 2009 musical/comedy/drama film set in 1969 about the beginning of Aboriginal rights.The different perspectives are from Colonial/Indigenous people. The voices were through the role of the characters, the genre, the music and the cinematography.

Personal sensing devices are becoming more commonplace in everyday life. Unfortunately, radio transmissions from these devices can create unexpected privacy concerns if not carefully designed. We demonstrate these issues with a widely-available commercial product, the Nike+iPod Sport Kit, which contains a sensor that users put in one of their shoes and a receiver that users attach to their iPod Nanos. Students and researchers from the University of Washington found out that the transmitter in a sneaker can be read up to 60 feet away. Through the use of a prototype surveillance system, the researchers could track someone wearing Nike+iPod sensors, plot their location on a GoogleMaps-based website and emai and

The purpose of this lab is to better understand the process of natural selection and its effects on a population by conducting a stimulation. The stimulation consist of predators (students with either a spoon, fork or a knife) and prey (different types of beans). Furthermore, students will be able to determine how phenotype (bean color and utensil used by the predators) influences natural selection. Students will also demonstrate their quantitative skills by determining the predator survival and reproduction, bean survival and reproduction, and by calculating the total percent of the population. Additionally, students will be able to identify the occurrence of evolution by natural selection after the end of generation three. Moreover, students

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.

Darwin’s Theory of Natural Selection, a scientific theory that supported the belief of evolution, was manipulated and applied to different areas of life, and thus it became the shaping force in European thought in the last half of the nineteenth century. Darwin, through observation of organisms, determined that a system of natural selection controlled the evolution of species. He found that the organisms that were most fit and assimilated to the environment would survive. They would also reproduce so that over time they would eventually dominate in numbers over the organisms with weaker characteristics. This new theory was radical and interesting to the scientific world but its effects reach far beyond this small institution of

Charles Darwin first suggested how evolution occurs in the natural selection process. Natural selection is the survival and reproduction of individuals with different phenotypes resulting in interactions with the environment. Genetic drift and gene flow can contribute to evolution too. Genetic drift is a random change in allele frequencies of a population. Gene flow is the movement of alleles between two or more populations. This is how populations evolve. In this lab, I completed an activity about Darwinian snails. A biologist named Robin Seeley suspected that New England’s periwinkle snail population was evolving due to predation by green crabs and she compared the old shells of these snails to the new ones. Robin Seeley recorded her results from the shell measurements to find the difference. It turned out that the range in shell thickness was different from 1980 and 1871. We completed a simulation online about the Darwinian snail population and the green crab population. This lab taught me the roles of mutations in introducing new genetic variation within a population! Populations evolve by the means of natural selection. I now understand the role of genetic variation, inheritance, and selection the evolution of a population. Being aware of the great diversity of living things on earth is just as important as knowing the long process of evolution. This lab was more than worth

1. There are many ecological and biological factors that affect evolution. In EvolutionLab, two populations of finches are tracked over the course of 300 years on two different islands to see how changing the traits of the birds and their environment affect their long term viability as a sustainable population. Let’s begin by doing a “null experiment” where conditions are identical on the two islands.

The main purpose of this lab was to utilize the infamous Hardy-Weinberg equilibrium equation to predict the evolutionary modifications a certain species (Drosophila melanogaster) displayed throughout different generations. For this experiment to be carried out, Drosophila melanogaster, also known as fruit flies, were used to visually represent evolutionary conceptions such as Hardy-Weinberg equilibrium equation. At the beginning of the experiment, the parent generation was observed first. Throughout the course of seven weeks, the vial was analyzed for certain changes between the two populations of Drosophila melanogaster; wild type and ebony. Although the genotypes could not be figured out, the flies were evaluated and observed based on

The Peppered moth is an example of modern-day natural selections since due to the environmental changes that occurred in the nineteenth century, the black wing moths were more suited to the new environment changes. Due to this, the black wing trait became more common in succeeding generations while the white with black speckles trait became less and less common among the population. This is a clear example of natural selection or the survival of the fittest.

This lab is a fundamental example of Darwin’s theory of Natural Selection because it clearly shows the changes in population that were created because of traits that were considered to be the most advantageous in certain environments. These desired traits were then passed down to subsequent generations leading to a change in the overall genotype and phenotype frequencies of the population. This lab investigation also demonstrated the importance of environment in the role of natural selection. If the brown snails that lived in the grassy field had moved to a different location or had the environment changed, such as the grass in the habitat dying and turning brown, then their survival rates would have been much different.

“If no such variations exist, the population rapidly goes extinct because it cannot adapt to a changing environment” (O’Neil, 1998-2013). Scientists call this reproductive success. “Within a specific environment context, one genotype will be better than another genotype in survival or reproduction for certain reasons having to do with the way its particular features relate to the environment or relate to other organisms within the population” (Futuyma, 2000-2014). The theory of evolution is explicable through various kinds of scientific research.

The simulation accurately demonstrates the variation in traits and the ability of the best adapted to survive easier when simulating the process of natural selection. However, the simulation doesn’t accurately demonstrate natural selection due to the lack of heredity. In the game, the light and dark moths flew across the screen in the same numbers throughout the simulation, not showing how there would be less and less of the moths that weren’t the same color as the forest, which is how heredity works in the real world. In the Light Tree Forest, the average percentage of dark moths that remained was 49.3%, and the average percentage of light moths that remained was 50.6%. Since there wasn’t a dwindling of the population of black moths, for many

Melanin has played a significant role in human evolution. In this paper I will discuss the importance of melanin in its role in the human biological system and how it relates to the natural selection of suitable human life according to geography and environment.

This means they were eaten by predators more often and thus could not produce as often. The black moths on the other hand could blend in easier and survive to reproduce more often. Overtime, the majority of the black moths had turned black. This is evidence to Darwin’s theory because it shows how species constantly change and adapt to meet the needs of their environment (Reece, 2011).
