Anth. 105 Human Species – Lab 2 ReportShahlo HaydarovaMarch 15 2018IntroductionEvolution is a change in the genetic structure of a population and change in allele frequencies in a population through time. There are four forces of evolution: mutation, gene flow,genetic drift and natural selection. Mutation is a change in DNA, that results a new variations of the alleles, and has an effect to increase allele diversity within population.Gene flow is exchange of genes between populations and increases allele diversity among the groups. Genetic drift is change in allele frequencies produced by random factors, and it decreases allele diversity. Natural selection changes in allele frequencies in a population due to differential reproductive success and it works on the fit between an organism and its environment.In this lab we will be using a simulation that displays an environment of bunnies. In this project, we investigated the effects of environment and other selectional factors such as predatorsand competition for food on a given population. Using an interactive simulation program from the University of Colorado Boulder, we are able to see the changes of allele frequencies through natural selection. In the simulation, we are allowed to change the environment from the equator
