Evolution Lab

Associate Level Material Appendix O EvolutionLab Report |Ful | | |Date | | Use this document to report your findings from the EvolutionLab Exploration Experiment. The lab report consists of three sections: Data, Exploration, and Lab Summary. Data: copy any data, graphs, charts, or notes that you have saved in your EvolutionLab online notebook into this section. Exploration: Answer the questions.
The questions in the Exploration section are the same questions in your EvolutionLab instructions. Lab Summary: Write a 100- to 200-word summary. Data To copy your data from your online notebook into this section, click on Export Graph and then copy and paste your data into this section. You must disable your pop-up blocker before exporting. Identify each set of data with a title. Exploration Answer the following questions in fewer than 100 words: Activity 1: Modes of Natural Selection What type of selection is taking place on Wallace Island? Explain.
Directional Selection is taking place. The beak size is increasing on Wallace Island from 11. 85 to 19. 13, and the population is increasing as well. This is because there are more seeds available that the birds can eat. What type of selection is taking place on Darwin Island? Explain. Directional selection is taking place. The beak size increases slowly, from 12. 47 to 26. 95. The population decreased because of the lack of seeds available for the birds to eat. Explain the reason for any differences in population numbers between the two islands.

The population increased on Wallace island because there were more seeds for the birds to eat, meaning there was more of a chance for them to survive and reproduce. The population decreased on Darwin island because there were no seeds for the birds to eat and without an abundant food supply they can not reproduce. Activity 2: Extinction Develop a hypothesis to predict what conditions would lead to extinction of a finch population. If there was no participation on a small island the Finch would become extinct.
Which of the parameters is most important in determining whether a population goes extinct? Variance is most important What are at least two different sets of conditions that may lead to extinction? Small Island, no precipitation Small Island, No variance Summarize the steps you took to complete the experiment you designed. I set the parameters on precipitation to 0, and the island size to . 3km. I then ran the experiment for 300 years. Summarize the result of the experiment you designed. The Finch was extinct by 2033.
The beak size stayed the same until extinction. Lab Summary Address the following points in a 100-to 200-word summary: Summarize the general principles and purpose of the lab. This lab is designed to help understand how precipitation, variance, and area have a role in the evolution of a species, in this case, Finches. It also explains the different types of selection. Explain how this lab helped you better understand the topics and concepts addressed this week. This lab really helped explain the concept of evolution.
Not only did it cover population grown/ decrease but it also covered the changes that animals go through to adapt to their ever changing environments. Describe what you found challenging about this lab. I did not really find anything challenging about this lab. The information was very easy to understand and the set up was easy to work with after completing previous labs. Describe what you found interesting about this lab. I found it interesting to see how one parameter can have such a large effect on a species, even over a relatively small (300 year) amount of time.
