Natural Selection-Evolution Natural selection is the evolutionary process through which factors in the environment exert pressure, favoring some individuals over others to produce the next generation. Charles Darwin (1809-1882) formulated this theory that has stood the test of time. Natural selection is important to anthropology for understanding how species change. Anthropologists emphasize the complexity of evolution and how natural selection is much more than â€Å"survival of the fittest.† Charles Darwin began the observing diversity of living creatures as well as fossils and extinct animals. Darwin noted that species varied according to the environments they inhabited. Darwin’s most famous book, On the Origin of Species, was published in 1859 and talked about a theory of evolution accounting for change within species and for the emergence of new species in purely naturalistic terms. Darwin noted in his autobiography that â€Å"It at once struck me that under these circumstances favorable variations would tend to be preserved, and unfavorable ones to be destroyed. The results of this would be for the formation of a new species. Here, then I had at last got a theory by which to work†. Natural selection theory and observations noted that all species display a range of variation, and all have the ability to expand beyond their means of subsistence. Organisms with variations that help them survive in a particular environment will reproduce with greater success than those without suchShow MoreRelatedEvolution Of Evolution And Natural Selection967 Words   |  4 PagesEvolution and Revolution What do a sponge and bird have in common? Believe it or not, they share a common origin. In the film, Darwin s Tree of Life, the narrator, David Attenborough, presents the audience with the theory of evolution as documented by Charles Darwin in the 1800 s. The video is based on Darwin s perspective of evolution and natural selection. Darwin s findings were revolutionary and caused out-rage among the religious who believed in the story of creation beginning with AdamRead MoreEvolution And Evolution By Natural Selection1222 Words   |  5 PagesIntroduction Arguing for evolution by natural selection to be stated as a fact is a wholly misplaced argument. Evolution by natural selection is a theory and theory is just a five letter word for an idea that cannot yet be proven. Such is the case in the arguments for and against evolution by natural selection. Looking at the weakness of the theory of Darwinian evolution is the perfect place to start to argue against evolution by natural selection.

Evolution refers to change over time due to natural selection as organisms adapt and diverge to produce multiple descendant species (Huxley L., Walter M., 2005, p. 698). Two pillars which form the basis of all current knowledge of evolution originate from the historical record of evolutionary change, fossil record and the study of the process of evolutionary change, specifically the effect of natural selection.

There is estimated to be between 6 million and 100 million different species in the world, with more species undiscovered than those discovered; this is all owing to the concept of evolution (Borenstein, S. 2014). Evolution is defined as the â€Å"change in the characteristics of a species over many generations (Linstead, 2012).† The most widely accepted theory of evolution is natural selection, whichRead MoreThe Theory Of Evolution By Natural Selection965 Words   |  4 Pages The beginning of life on earth was always thought out as Gods creation and evolution was just a mystery in itself. Many people have always been interested in their origins and have found explanations using evidence that validates the story, bu t where is the proof? In 1859 a man by the name of Charles Darwin wrote a novel called the Origin of Species basically expressing the theory of evolution by natural selection.

Changes that allow an organism to better adapt to its environment will help it survive and that have more offspring.

Evolution is the changed caused by natural selection. The effect of the inheritable elements on their own frequency in succeeding generations. (Inheritable elements replaced the words generations). The variation within species and reproductive success are the basis of natural selection.

Darwin was born on February 12, 1809, in Shrewsbury, England. While Darwin was still in high school, his main interest was nature, he was especially interested in beetles. Darwin’s father, Robert Darwin, who was best known as the father of the naturalist Charles Darwin, wanted Charles to become a doctor.

It is responsible for the unusual carnivorous plants (species such as Dionaea muscipula), the beautiful coloured plume of the male peacock, even the possibility of cells adapting to protect against continual low exposure to radiation (Russo, GL. et al 2012).

In school we are often taught that natural selection is survival of the fittest or the strongest wins. What seems to be a simple topic is actually one of the leading theories on the side of evolution in the highly controversial debate on Darwinism vs. Creationism. Darwinism states that certain genes in a population change through individuals. These â€Å"strong† genes are then produced more
