Evolution: Fact or Fiction? :: Exploratory Essays Research Papers
Evolution Fact or Fiction? One of the greatest questions of each time is Where the heck did we bed from? One of the most popular answers to this question is creationism, the idea that everything was created by a higher being. Another idea is phylogenesis, the idea that all living organisms descended from a less(prenominal) complex organism. Up and coming in the last century, evolution possesses a new focal point of thinking that is being greatly accepted by the scientific community. Despite this fact many people argue that evolution has no facts to support it and there are several reasons why evolution cant happen. Evolution is the sluggish change in an organisms gene pool over time, basically evolution is described in any change in the genetic makeup of an organism. The easiest way to show this is by stating examples of low level evolution as it has been observed. The best know case of this kind happened in England during the industrial evolution. There were two varieties of the slope Peppered moth before the revolution, a slack and a dark colored moth. The dark moth was almost nonexistent, as it was easy for predators to catch on the light colored trees. As the industrial revolution progressed, the amount of pollution in the air turned the trees a soot color, and as a result the light moths were easy for predators to spot. The light colored peppered moth all but died out, and was on the verge of extinction while the dark colored moth was thriving. In the last several decades the pollution in England has dropped and neat moth is making a come back, and the dark moth is heading back towards oblivion. (Harter) The moth example is considered by many to demonstrate evolution, but people against the idea of evolution range it isnt. The only thing that it showed was that nature uses natural selection to weed out the weaker of the stocks. The moth case is a clear example of natural selection not evolution because no change in the gene pool of the moth happen ed. Saying that the peppered moth example doesnt show evolution is preposterous. Natural selection is one of the greatest tools of evolution, as express by Charles Darwin in his book, Origin of Species. It may be said that natural selection is daily and hourly scrutinizing, throughout the world, every variation, even the slightest rejecting that which is bad, preserving and adding up all that is good wrote Charles Darwin in chapter 4Natural Selection.
