Each lesson consists of 10 activities.   We suggest that you proceed through the lesson in the order that the activities are presented.  Should you NOT complete a particular activity, remember to go back to it as soon as you can.

Send Dr. Cauthen an E-mail as soon as you know you have a question... or you may put a message on the Bulletin Board on WebCT.  If you need help with WebCT, you can get a tour at:

I. Introduction to Lesson 8

  to Lesson 8!!

In previous lessons, we have been working at the cellular level of organisms and in Lesson 6 we moved to the organismal level.  In the last lesson, your survey of living organisms took you to the invertebrates.  In this lesson you will leave the world of the invertebrates and visit the diverse groups of the vertebrates that populate our world.  Lesson 7 dealt with the major invertebrate phyla and classes and Lesson 8 will deal with the major subphyla and classes of vertebrates.

In Lesson 8 you'll find the diversity among invertebrates matched by that of vertebrates, the branch of the Animal kingdom where our closest ancestors made their first appearance. From the early chordates and jawless fishes, you'll follow our phylogenetic tree through the more familiar branches—amphibians, reptiles, birds, and mammals—ultimately leading you to the place Homo sapiens occupies in the vast scheme of life.

II. Objectives

Click here to review the objectives for Lesson 8. This is a VERY important step, as we let you know in the objectives exactly what you need to know.

III. Key Terms

Familiarize yourself with the key terms below.  They are used in the text, the tutorial, the Interactive Study Partner, and the Cycles of Life Video.
 

IV. Text Pages 

Read Chapter 18, The Evolution of Animal Diversity pp. 385-394.

V. Interactive Concepts in Biology CD-Rom 

Put your Interactive Study Partner CD-Rom into the CD player on your computer. This is VERY important for this lesson!!

• Proceed to Activities
• Choose Chapter 18
• Choose 18A, Characteristics of Chordates
• Complete the entire exercise
• Choose 18B, Animal Phylogenetic Tree
• Complete the entire exercise
• This exercise allows you to review vertebrates and invertebrates.
• Take the quiz listed as separate from the activities.

 

Watch Video Lesson 13 - Part Three, Fungi, Plants, and Animals.  The video is about 28 minutes in length but we are only focusing on part three for this lesson.

Click here for a viewing guide for the video. Answer the questions in the viewing guide before proceeding.

VII. Tutorials 

Click on the tutorial button to guide you with the concepts.  I wrote the tutorials for you, and it will hopefully reinforce important points and clarify some of the concepts.

  Lesson 8 Tutorial for Animal: The Vertebrates

You may open the tutorial with Internet Explorer or you may save the tutorial to your hard drive.  You can then view the file in PowerPoint and print it out if you wish.  You must use all links, and make notes as you go through the tutorial.  Please have your CD in the drive while you work on the tutorial.  You might decide to review from it.

Warning:  Downloading the tutorials using a modem may be slow.

VIII. Web Links 

To refine your studies you will need to go to the Internet (WWW), and work with more sources.  Proceed to the following.

1. Read the summary of Chapter 18 from the Campbell Web Site.
2. University of Ohio Animal Diversity labs containing various images by Phylum.
3. Introduction to the Chordata: From sea otters to sea squirts
4. Click on the button below to go to the Biology Place on the Internet. 

• Go to Biology News
• Check out any topics of interest, but most especially
•   New Evidence for the Emergence of Modern Mammals and Birds
•   Researchers Muscle in on Bird Evolution Theory

A well-preserved dinosaur fossil suggests that meat-eaters called theropods could have been cold-blooded and still able to catch swift prey. The findings also have cast doubt on a theory that birds evolved from theropods.

• Frogs are disappearing.... read some theories about why this is happening!!
• Go to the Web links ... these are great.  

  Coelacanth, a 400 million year old "living fossil" fish

  • You can go to Sea World!!
  • The lobed-fin fish ("dinofish").... a living fossil.  Look to the right!

Study Guides and Practice Tests enable you to assess yourself and your progress.

• Review Chapter 18 questions that pertain to vertebrates in the Study Guide
• Review the quiz from the CD-Rom, Interactive Study Partner.
• Take the practice quiz on the Campbell Web site
