    Hazing is an issue that has attracted much attention over the last few decades. College fraternities, high school programs, professional sports, and the military have all had their fair share of attention. The military is frequently held to a higher standard than these other organizations and has developed a bit of a black eye since the 1991 “Tailhook” scandal. Motion picture portrayals like that in the 1992 film “A Few Good Men” showed the public, not inaccurately, the dark side of command sponsored hazing. Hazing is not in keeping with the high standards of conduct that the U.S. Military aims to uphold and the ethical implications of these behaviors are diverse.…

    Mutations

    • 282 Words
    • 2 Pages

    Mutations can lead to genetic variations by producing random changes in an organism’s genetic coding. This causes a different protein to be produced, or none at all. Mutation usually has a negative effect due to an important protein and enzyme not being produced, so the organism cannot preform its original function.…

    What is albinism? Albinism is a genetic disorder that can affect all organisms with vertebrae. What does it do? Simple, Albinism causes a partial or complete lack of pigmentation in an organism. Or in layman terms, people affected with albinism lack the chemical that makes their body a certain color, be it black, yellow, or red. They’re also characterized by their glowing red eyes, making them often accused of being possessed by the devil. Albino’s are also unnaturally pale and also lack color in their hair, giving them a very ghost like appearance. Here we look into what Albinism really is.…

    Genes

    • 2227 Words
    • 9 Pages

    A gene is a sequence on DNA that has a specific region on the chromosome, which determines a particular characteristic in an organism. For many years it has been thought that there are specific genes responsible for certain behaviour and so there is a gene for criminal behaviour. In the first half of the twentieth century psychologists studied the heritability differences of people and had an aim to improve the gene pool within humans (Kevles, 1985; Duster, 1990 & Paul 1995). There research did not lead to much good for the human race but rather restrictive immigration policies and sterilisation laws in western countries. Also, Nazi Germany who always had an idea of ‘improving’ humanity had mass sterilisation and euthanasia within their country. Following World War two the study of genes improved compared to past years, techniques came available which could isolate and manipulate genetic material. To this day these techniques are being used to assess patterns of inheritance. Although it is not certain which genes cause criminal behaviour there are ongoing studies which may provide the answers. In recent years research has concentrated on the genetic influences on criminal behaviour, the emphasis has been moved from environmentalist approach. Environmentalists argue that that genetic explanation of criminal behaviour involves medicalization of social behaviour and diverts thoughts away from social and economic conditions (Wasserman & Wachbroit, 2001).…

    Evolution

    • 295 Words
    • 2 Pages

    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 person who pretends to any understanding of the natural world can deny these facts any more than she or he can deny that the earth is round, rotates on its axis, and revolves around the…
