Introduction

      In the 1800's, there were two major theories presented on evolution.  One was described by Charles Darwin and the other by Jean Baptiste Lamarck.  Some questions that could be answered by the theories might sound like this, "Did giraffes get their long necks by stretching and then passing that trait to offsrping?  Did giraffes get their long necks through a series of small changes that took place over thousands of years?  If I lift weights and get big mucles, will my children have big muscles?  Why are humans and chimpanzees so similar?"
                                                                                                               Darwin                                                           Lamarck

The Process

    1. Each student will work on this webquest individually.
    2. You will answer the questions by going to the websites that I have picked out.
    3. You will answer the question on the attached answer sheet and then print it out.
    4. Use the webpage called Darwin and Natural Selection to answer the following questions.
       
             a. What county was Charles Darwin from?

             b. Which islands did Darwin visit and make many observations?

             c. Describe Darwin's theory of Natural Selection.

    5. Look under the heading "Lamarck's Scientific Thought"from the webpage called Jean-Baptiste Lamarck to answer the following questions.

                d. What did Lamarck mean by "use and disuse"?

             e. Could these acquired traits be passed on to offspring?

             f. How many generations did it take to see a change?

    6. Use the webpage called Adaptation: Mimicry and Protective Coloration to answer the following questions.

             g. What is mimicry?

             h.  What are some other ways that organisms tryo to avoid predators?

    7. On the webpage The Arts of Deception: Mimicry and Camouflage , look under the heading "Camouflage" to answer the folowwing questions.

             i. Why might an organism want to be camouflaged?

    The next section deals with some of the evidence for evolution.

    8. Based on the picture and its caption, from the website on Homologous Structures ,

            j. what do you think homologous structures are?

    9. Whales have pelvic bones.  Pelvic bones allow legs to atach to the body.  Use the webpage on Vestgial Structures to

            k. decide why whales may have needed pelvic bones in the past.

    10. Once you have completed these questions, create an image, animation, cartoon strip, etc. that explains and shows the main ideas of natural slection.  Create this document using Powerpoint.  When you have completed it, e-mail to me at mouimet@gw.neric.org.
