Animal Phylogeny

Cladistics is a method of biological classification where organisms are classified based on their ancestors and their relationship with them. It is defined as the concepts and methods for determining the branching patterns of evolution and evolutionary history. Some scientists, however, have preferred the term phylogenetic systematics or phylogenetic taxonomy to emphasize the reliance on a phylogeny for classification. It is the most common and accepted method for classifying organisms.

Create a body plan table (Insert → Add Table) for the following animal phyla: Porifera, Cnidaria, Platyhelminthes, Mollusca, Annelida, Nematoda, Arthropoda, Echinodermata, and Chordata. Describe each phylum by identifying the following body plan features. Use Lesson 12 (Chapter 32) and Lesson 13 (Chapter 33) as a guide. 1) Symmetry: Asymmetrical, Radial, or Bilateral 2) Tissue type: Parazoa, Eumetazoa (diploblastic), or Eumetazoa (triploblastic) 3) Body cavity (if triploblastic): Acoelomate, Psuedocoelomate, or Coelomate 4) Developmental mode (if Coelomate): Protostome or Dueuterostome Note: Depending on the body plan, features 3 & 4 may not apply to specific phyla. * Please answer 3) and 4) ONLY.

Using the examples from the animals you have studied in this lab, give the differences between the following phyla: Echinodermata and planaria Cnidaria and Porifera Annelida and Nematoda Cnidaria and Mollusca Echinodermata and Chordata 2. Charles a Biology student in California has found at the beach an animal he cannot name. What are some of the questions that he should ask to help determine the phylum of the animal? Based on the data that you recorded during this lab do you see a relationship between symmetry, cephalization, and number of germ layers? Can you tell what germ layer appears last? Name three characteristics or features in the phyla studied that you could tell are ancestral or primitive and three that you may call advance? Explain further?
