The Role Of White Furs In A Snowy Environment
Given a population of rabbits of which 50% are white and 50% are black. If this population resided in a snowy environment, the black ones would be spotted quite readily by predators which would cause a decline in the black-rabbit population. The white-rabbits population however would thrive in such an environment and be more inclined to pass on genes through sexual reproduction. Over the course of time only white rabbits would remain. Thus the gene which causes black fur would “edited out”. *** I would imagine the only manner in which natural selection could be described as a “creative process” is if there was some kind of BENEFICIAL genetic mutation that enabled an organism to survive within an environment.*** The wings of a bat and a bird

    The basic idea of natural selection is that a population of organisms can change over the generations if individuals having certain heritable traits leave more offspring than other individuals. The result of natural selection is evolutionary adaptation, a prevalence of inherited characteristics that enhance organisms’ survival and reproduction in specific environments.…

    Both the Pocket Mouse and the Peppered Moth’s environment changed in color from light to dark from a major environmental impact, causing both species to adapt. The best fit organism for the environment at the time continued to reproduce until their color changed over time, and adapted to become better camouflaged from predators. The Peppered Moth and the Pocket Mouse both carry the genetic mutations of a dark color allele in the gene pool as opposed to only a light colored allele, which is the reason natural selection was able to occur and this adaptation affected the population in that specific…

    As a result of natural selection, a population—a group of individuals of the same species living in the same place at the same time—can change over generations. Natural selection leads to evolutionary adaptation, a population’s increase in the frequency of traits suited to the environment (Simon, Reece, Dickey, 2010).…

    In general, you should understand how evolution is operating on the population level. The individual organisms carry the genes that natural selection acts upon, but it is the genes of the population (gene pools) that evolve.…

    This hands-on laboratory exercise is a highly simplified model that attempts to simulate evolution by means of natural selection. Predators will act as agents of selection on their prey, a species whose members vary in color. We will assume that color is an inherited trait. Small squares of paper will represent the prey, which will be spread out of a piece of printed colored fabric that will serve as the habitat. The predators (you) will prey upon the population, with the surviving members reproducing and passing along the genes for color.…

    The way organisms evolve is a very delicate process, and a number of factors can influence this. A prime example would be the recent evolution of the wild Soay sheep residing on the Scottish island of Hirta. First of all, this changing environment is producing variations to this species in ways that evolutionists would not expect. In addition, the impact of these changes is widespread throughout this population, and will lead to many differences from previous populations of these sheep. Finally, the way the environment is affecting natural evolution of this species is different than many people would suspect. Overall, the changing environment of the wild Soay sheep is giving rise to altered natural selection forces and thereby causing evolutionary processes.…

    Hunters in the snow is a short story about three unique men on a hunting trip. This story takes place in the winter outside of Spokane. The mode of transportation is an old truck with a hole in the windshield, making it a very cold journey. Each of the characters has a secret they are concealing from the others. Tub hides food and blames his obesity on overactive glands. Frank conceals the fact that he is in love with his 15 year old babysitter. And Kenny, the comedian, doesn't tell the others that a farmer asked him to shoot his dog.…

    Evolution is defined as a slow and steady change in the same species to help their survival. There were two theories on this type of evolution: Lamarck’s theory of acquired characteristics and Darwin theory on natural selection. Both scientists agree that evolution is caused by the need of survival. Natural selection is the process by which biological traits of an organism become less in common in a population over time. This process can even result in a different species. Polar bears have gone under a series of evolutionary changes over time to help them survive in conditions on the planet some such adaptations include larger paws, thicker white fur, extra fat to keep them warm and more recently they have developed polar bear type teeth. These…

    The peppered is a very good example of natural selection because there is already black moths in the population, but the peppered survived better before the industrial revolution.Though when the industrial revolution comes in the lichens on the trees die and the peppered moth begins to be eaten more by birds and black moths survive and become more common. This shows that the variation in the population helps because if the moths didn't have variation and were all peppered they would have all eventually died out. Natural selection made the colors of moths change to black during the industrial revolution.…

    Darwin's theory resides on the presence of Natural Selection in the animal kingdom. This means that favorable genetic mutations are "selected" for in nature, thus accounting for complex and highly specific organisms. The selection of favorable genetics is driven through competition for resources and the production of progeny. However, natural selection is a process dependent on random mutations of an organism’s genetic material. It hinges upon the fact that organisms obtaining randomly generated mutations, that provide a selective advantage in their environment, are more likely to form progeny and pass on their…

    The natural selection operates in base of the difference between de reproductive successes of the individuals. The genes of the most successful individuals (the ones that reproduces more) appears more in the next generation. If an individual cannot survive it will not be able to reproduce. Because of that natural selection is NOT RANDOM and can act really quickly. (Charlat et al., 2007)…

    The theory that members of a species each have slight variations from each other, and that these variations have the ability to enable some members of a species a survival advantage in certain environments. As a result of having a variation that increases their likelihood to survive, they are allowed to propagate, and their offspring have an increased likelihood of survival with the passage of the variation. Other members of the species who lack the variation die, and over time the only surviving members of the species are the ones who possessed the variation that gave them the survival advantage.…
