Natural Selection Project |
|
|
|
|
|
|
| Objective |
|
Given access to the CPH wireless network and a background in the use of laptop computers, students will be able to access a Hotlist of Web sites, review the details of the process of natural selection as set forth by Charles Darwin, and produce a detailed summary of this process including the factors involved and a specific example. |
|
|
|
|
| Standards |
|
10.1 - Explain that evolution is the result of genetic changes that occur in constantly changing environments. (CS 8)
10.2 - Demonstrate how new mutations and sexual reproduction lead to genetic variation in a population and diversity in its gene pool. (CS 7c)
10.3 - Show how natural selection acts on the phenotype rather than the genotype of an organism. (CS 7a)
10.4 - Explain how genetic drift affects the diversity of organisms in a population. (CS 8c)
10.5 - Explain that reproductive isolation, which results from behavioral, geographic, and/or temporal isolation, leads to speciation. (CS 8d)
10.6 - Give examples of how natural selection determines the differential survival of groups of organisms and how great diversity of species increase the chance that some organisms will survive major changes in the environment. (CS 8a, 8b)
10.7 - Identify and categorize the evidence of evolution, including comparative embryology, DNA or protein sequence comparisons, fossil comparisons (including episodic speciation and mass extinctions), comparative anatomy, and how this evidence is used to show probable evolutionary relationships. (CS 8e, 8f) |

| Assignment |
|
You are going to review a set of Websites concerning the details of natural selection. After your group has reviewed all of the sites, produce a typewritten summary of the process of natural selection. Be sure that your response includes each of the items listed within the guidelines found at the bottom of this page. |

| Guidelines |
|
As you complete your natural selection paper, use the list below as a template for your responses. For a word document of these guidelines, click HERE. |
|
|
|
1. Outline the relationship between biological evolution and the process of natural
selection.
2. Identify the factors that function within the process of natural selection.
3. Discuss how these factors interact to allow organisms with the highest fitness
within a population to survive and reproduce.
4. Examine the concept that natural selection acts upon the phenotype rather
than the genotype of an organism.
5. Provide a specific example of how natural selection alters the allele frequencies
within a population.
6. Predict the outcome of a population that is reproductively isolated and placed
under the pressures of natural selection. |
