Name___________________ WebQuest Activity: Evolution Resources / Text References: Biology Textbook: Chapters 15 – 16 WebSite: Evolution Click on Definition & Answer the Following Definition: How is evolution defined? Patterns: What patterns in diversity over time are produced by evolution? Mechanisms: How does evolution work? Microevolution: How does evolution work on a small scale? Speciation: What is a species and how do new ones evolve? Macroevolution: How does evolution work on a large scale? Big Issues: What are the interesting questions about evolution that are currently being investigated?

Click on Mechanisms then Descent & Answer the Following Which example of changes in a Beetle population is an example of evolution. Explain how this demonstrates descent with modification. Diagram how this example of beetle evolution could occur. Why are pink flamingoes pink? Explain whether or not the coloration of flamingoes is a result of evolution. Click on Mechanisms then Mechanism of Change & Answer the Following Describe and explain four mechanisms of change of evolution. Click on Mechanisms then Genetic Drift & Answer the Following Give an example of genetic drift. Diagram to enhance your explanation.

Click on Mechanisms then Genetic Variation & Answer the Following What are three sources of genetic variation in a population? Explain each one. What does the Lederberg Experiment conclude? What are two causes of genetic mutations? What effects do gene flow have of the evolution of a population? How does sexual reproduction cause genetic shuffling? Explain how ontogeny supports the idea that living things share common ancestors.

Click on Mechanisms then Natural Selection & Answer the Following Explain in detail how natural selection works. Give an example. Explain how artificial selection differs from natural selection. What is fitness? What are adaptations? Give three examples of adaptations. Click on Micro-evolution and Macroevolution & Answer the Following Explain how micro-evolution differs from macro-evolution. Click on Speciation & Answer the Following What is a species? What causes speciation to occur.
