  • Biston Betularia

    Industrial Melanism of Biston Betularia or the Peppered Moth in England has been a textbook example of natural selection since it was first noticed. Before the industrial revolution the peppered moth was most commonly found in the light colored Typica variety. During the industrial revolution there was a significant rise in the dark Carbonaria form and a slight rise in the intermediate Insularia form. Beginning in 1970 the Typica variety has been rising in frequency again. Carbonaria went from an estimated 95% of the population down to 5%.(Cook et al 1986) This change has been assumed to be caused by increased predation on moths that did not blend into the bark of trees (Cook et al 2012). Before the industrial revolution the trees were light…

  • Natural Selection And Descent With Modification: Theories Of Evolution

    Evolution has always been a subject of questioning discussion ever since Charles Darwin established the theories of Natural Selection and Descent with Modification. According to Darwin, some animals were born with certain characteristics that became advantageous for their particular environment. As time passed, however these organisms modified some of these physical characteristics that they were born with in order to survive in their particular environment. This modification allowed the…

  • Natural Selection Evolution

    force, and evolution as a result. Natural selection can be broken down into three concepts that require it to operate. The first is the constant struggle a species face for survival, which results in the continuation of the successful branches of the species, as the others become extinct. The second requirement is a varying population, these more successful branches only stem from mutated groups or individuals whose features become beneficial when faced with such struggles. The third concept is…

  • Natural Selection And Variation: Polar Bear, Peppered Moth

    mutation are always taking place together. They are the basic process of evolution. Natural selection means those organisms that fit in theirs living environment will be survive. There are three kinds of mutations: positive, negative or neutral. Natural selection is always going to decide a mutation. Ether it is positive, negative or neutral. Here are three examples of positive mutation: Polar bear, peppered moth, and giraffe. Polar bears live at the North Pole. A lot of people think that…

  • Evolution As A Lesson

    Evolution as a Lesson According to Dennis O’Neill, biological evolution can be defined as, “genetic change in a population from one generation to another” (“Early theories…”, n.d.). Contrary to what some may believe or have been taught, biological evolution and evolutionary theory do not suggest that humans come from monkeys. Rather, they suggest that organisms share a common ancestor somewhere down the line, and that that common ancestor can be held accountable for similar traits among…

  • Misconceptions About Biological Evolution

    The theory of biological evolution through natural selection is widely accepted and taught in most western education systems. However, there are many misconceptions regarding evolution, held both by proponents of evolution and by those opposing it. Generally, these misconceptions occur due to a misunderstanding or ignorance of how evolution functions, due to an over simplistic version of it being taught (Scott, 2004). The four misconception that will be discussed in this essay however, will be:…

  • The Everlasting Argument Of Evolution Vs. Creationism

    The everlasting argument of Evolution and science vs. Creationism and religion has been stumping mankind for ages. There really is no right answer but there is a more realistic argument. Which is the idea of Evolution and the continuous adaptation of species to their Environments. We have retrieved evidence supporting Evolution and the paths it’s taken to reach the stage it 's at now. Many scientist devoted their lives to research evolution. These Scientist were able to determine that we all…

  • Evolutionism Vs Creationism

    to explain the nature of organismal evolution, they are two very different theories. Creationism states that God does exists and he does interfere in the universe. Creationist believe in the design arguments and believe all that all complexities in our universe are products of intelligent design. While the two different interpretation of evolutionism, atheistic and theistic, both state that evolution happened and makes a biological argument towards evolution, they do contradict on the existence…

  • Nature Of Evolution: Selection, Inheritance And History

    The Nature of Evolution: Selection, Inheritance and History Name Institution The Nature of Evolution: Selection, Inheritance and History Many of us often relate the term evolution with the famous naturalist and man of science, Charles Darwin. As right as we may think we are, we are wrong and misinformed to think that Darwin came up with the evolution concept. Evolution had existed and occurred way before he was even born (O’Neil, 2012). Christ’s College (2009) gives examples of other…

  • Peppered Moth In London

    before reading Chapter 3 and 4 of our textbook, I never would have linked biodiversity with biological evolution and definitely not with natural selection or what I always thought of as survival of the fittest. However, it does make sense. Biological evolution is the genetic change in a given species over time that leads to modifications in appearance, functioning, or behavior that enable the species to thrive in its natural ecosystem. Such evolution is usually brought on through natural…
