I.    List and describe the three domains of living things and list some major organisms belonging to each domain.

II.   Explain why the following domain classification scheme is often used instead of 
       the traditional classification scheme starting with the kingdom which preceded it.



III.    State several characteristics of the universal ancestor indicated by the letter X.

IV.   Complete the following chart

V.  Describe the differences between the terms in each of the following pairs.

(a.) Coelomate versus psuedocoelomate versus acoelomate body plan
(b.) Protostome versus deuterostome development
(c.) Radial versus bilateral symmetry

VI.   Discuss how the characteristics listed in parts a and b of question number V were involved in the construction
        of the phylogenetic tree of the animal kingdom below.   Also discuss the significance of the hardly
        visible letter at the bottom of the phylogenetic tree. 

VII. Classify each of the following phyla of the Animal Kingdom according to the characteristics listed in part one above. Record your information in a chart like fashion. The phyla to be assessed are as follows; Porifera, Cnidaria, Echinodermata, Platyhelminthes, Nematoda, Annelida, Arthropoda, Mollusca, and Chordata. (Note: A phylum which is acoelomate or psuedocoelomate is obviously not either protostome or deuterostome.)
