Forces of Evolution Discussion In previous chapters we have studied how one of the forces of evolution (natural selection) acts to create changes in species along many generations. • For this discussion choose one of the OTHER forces of evolution: genetic drift/ founder's effect, mutation, non-random mating, or gene flow. 1. Chose and define your force of evolution. 2. Research and find an example of this force in action. 3. Describe this example to the class. 4. Explain why you chose this example and how it illustrates your chosen force. 5. Comment on two other people's posts.

Step 1
Chose and define your force of evolution: I choose **genetic drift** as my force of evolution. Genetic drift is a random change in allele frequencies within a population due to chance events, such as the survival and reproduction of individuals. This process can Show more…

1.) What are the four forces of evolution? 2.) Which of the four forces of evolution is NOT a factor in macroevolution (speciation)? (Hint: how do we define a species?) 3.) Is genetic drift more influential in small or large populations? Explain why.

LA 4 - Part 2: Evolutionary Forces There are four evolutionary forces that shape which traits are present within a population, and which get passed to future generations. These forces include mutation, gene flow, genetic drift, and natural selection. Instructions You recently reviewed a video called "The Five Fingers of Evolution" that described the different forces that act on populations to cause genetic change over time. Use information provided in the video to answer the following questions. 7. Which finger(s) in "The Five Fingers of Evolution" do you think represent genetic drift? Be sure to explain your answer. 8. What is gene flow, and what effects can it have on a population's gene pool? 9. What specific advantage(s) must a genetic trait provide in order to be "favored" by natural selection?

First, clearly explain the impact that the five evolutionary forces (mutation, migration, random mating, genetic drift, and selection) have on allelic frequencies in a population (5 pts). Second, choose one of the evolutionary forces and in clearly written paragraphs describe how it impacts a population over multiple generations by creating your own fictional population of an organism of your choice. Carefully describe how your population changes over time when the chosen evolutionary force is applied to the population (10 pts).
