    Genetic Drift as an Evolutionary Force Becky Gonzalez Genetics 2450 Lab Section 1262 March 2‚ 2011 Genetic Drift as an Evolutionary Force Genetic drift‚ along with natural selection‚ mutation‚ and gene flow‚ is one of the basic evolutionary forces of evolution. Evolution is the method by which allele frequencies in a population change over time. This process can be random‚ where the changes occur through genetic drift (Hahn and Bentley 2003)

L.‚ & Underwood‚ L. S. (2006). His theory contains two parts‚ the first part states that species change over generations. The second part states that what causes this change is natural selection. Inheritance: This is another theory by Gregor Mendel. He

    variation exists‚ and if there are differences in reproductive success or survival rates. Therefore‚ in response to environmental pressures‚ the frequency of heritable characteristics will change from one generation to the next‚ and evolution by natural selection will take place. …humans display greater genetic unity than most other species‚ which has led many to assume that human evolution ended with the origin of modern humans The modern theory of evolution—built on a vast array of supporting

    In “Selection Does Primarily Operate on Genes”‚ Carmen Sapienza argues that selection primarily acts upon genes. Sapienza supports this notion by defining Natural Selection as a process that allow one to distinguish between “biological entities”‚ and this process confers a reproductive advantage upon one of the “biological entities”. For Sapienza‚ this biological entity is defined primarily as the gene. Sapienza argues that genes are directly the main targets of selection. For direct selection‚ Sapienza
