Question
Chapter 30.4, Problem 3C
Summary Introduction
To draw: A cladogram illustrating the evolutionary relationships among three main clades of bilateral animals and the way in which they differ from one another.
Concept introduction: Animal phylogeny is the rapidly changing field. Biologists associate the variations in body symmetry, types of body cavity, number of tissue layers, and pattern of development. To interfere with the evolutionary relationships among the animal groups, biologists nowadays compare the embryonic developments and the molecular level of variations.

Answer according to phylogenetic tree for animal phyla
1. Which phyla are radically symmetrical?
2. Which phyla are coelomates?
3. Which phyla are triploblastic? Explain what triplobastic means.
4. Which phyla have segmented bodies and a closed blood system?
5. a) Differentiate between an exoskeleton and endoskeleton.
b) Which phyla have these skeletons?
c) Give one advantage and disadvantage of each of this skeletons
6. Which phylum did not hive rise to any other group of animals?
7. Name one feature of the chordates that make them different from the other phyla
8. What was the common ancestor of all animals?
A) Draw a phylogenetic tree for the major phyla of the animal kingdom. Label the appropriate branch points on the tree with the following features: Tissue, radial symmetry, bilateral symmetry, body cavity, deuterostomes, and protostomes.
B). Draw a diagram of a hydra. On the hydra, label the mouth (hypostome), tentacles, basal disk, ovary, budding polyp, gastrovascular cavity. State the function of each structure you labeled next to or under your diagram.

- Differentiate analogous structures from homologous types. Identify which is which among the shark, pigeon and cat when you transition from each of the classes. For this, create a 4-column table with the following headings: (1) Structure, (2) Specimen a vs b, (3) Specimen b vs c, and (4) Specimen c vs a. For each cell, write either AS for analogous structures, or HS for homologous types. Note (not all structures encountered need to be here).arrow_forwardDownload a phylogenetic tree of Bilateria that includes the ten phyla of bilaterian discussed in this module. From the tree, be able to identify whether members of the phylum are coelomates (C), pseudocoelomates (P), or acoelomates (A). Use your labeled tree to answer the following questions: a) For each of the three major clades of bilaterian, what can be inferred about whether the common ancestor of the clade had a true coelom? b) To what extent has the presence of a true coelom in animals changed over the course of evolution?arrow_forward1 which two organisms are most closely related? 2.
