  • Whale Evolution and Classification

    Let's dissect this cartoon a little bit.  What's accurate?  What's inaccurate?  Why is the whale walking?  And why is it walking back into the water?

    With that as a backdrop, let's do a little classifying of whales.  Create a traditional classification diagram for the following organisms.  Use these IMAGES to help you with the classification.

    Go to the UNIPROT website.  Do an HBA ALPHA search for the following animals:


    Align the 12 organisms and study the family tree that is produced.  What is closely related to the whales?  What does that mean for the evolution of the whales?  What evidence would we see if this relationship is true?

  • Using Anatomy to Understand Evolution
    Go to UNDERSTANDING EVOLUTION, and complete the module over Homologies and Analogies.
    1. When we discuss analogies in evolution, we are really talking about convergent evolution.  Explain.
    2. What are homologous structures?  Give two examples from the module.
    3. What are analogous structures?  Give two examples from the module.
    4. Why are homologies solid evidence for evolution?
    Check out the link on HUMAN VESTIGES.
    1. What are vestiges, or vestigial structures?
    2. What are two examples of vestiges in humans?
    3. Why are vestigial structures solid evidence for evolution?
