When it comes to Darwin’s theory of evolution there are a lot of misunderstandings of what the meaning behind natural selection is. Now days, college students who have the opportunity to take an introduction to anthropology course are able to have any of their misconceptions about evolution confronted and, ultimately, walk out with a better understanding of how one’s environment works. When it comes to understanding how natural selection works one must understand the theory of evolution. This paper will describe what natural selection is, and demonstrate through the example of the Grant’s finches how supportive the process of natural selection is to the evolutionary theory. Darwin’s evolutionary theory is made up of four forces which are mutation, gene flow, gene drift, and finally natural selection. In the example of the Grant’s finches, the founder effect, a.k.a. genetic drift, is clearly described in the Natural Selection in Action: Galapagos Finches handout when it said, “This small founder population to survived and reproduced, and through genetic drift and natural selection accumulated sufficient variations over time to establish a variety of new species.” It is important to understand that the process of natural selection is closely linked to the environment a particular species inhabits. In the case of the Grant’s finches, there was described to be fourteen species of Galapagos finches, which evolved from a common ancestor. The Galapagos finches is a prime example of adaptive radiation because the Grant’s study displayed how the shapes of the finches beaks varied in order to best equip them for the differing habitats and diets they had. When learning about how the natural selection process works it is critical for one understands the three key points in which natural selection consists of. For natural selection to take place there first must be
