Chapter 33, Problem 7TYU
Evolution connection • Interpret thf data Draw a phylogenetic tree of Bilateria that includes the ten phyla of bilaterians discussed in detail in this chapter. Label eath brauch that leads to a phylum with a C, P, ur A, depending on whether members of thc phylum are coelomates (C), pseudocoelomutes (P), or acoelomatos (A). Use your labeled tree to answer the following questions:
- (a) For each of the threc major clades of bilaterians, what (if anything) 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?

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?
The phylogenetic tree in Exercise 1 above shows an outdated relationship between Brachiopoda, Bryozoa, and Mollusca. We now know that: (1) Brachiopoda is more closely related to Mollusca; and (2) Bryozoa forms the sister-group to the clade formed by Brachiopoda+Mollusca. In the space below draw a phylogenetic tree showing the correct interrelationships among the 5 clades listed:
Bryozoa:
Brachiopoda:
Linguliformea:
Craniiformea: Rhynchonelliformea:
Please include mollusca. Should be 6 classes total
Redraw the phylogenetic tree for Cnidarians showing only the relationships between Scyphozoa, Rugosa, Tabulata, and Scleractinia. Circle the Anthozoa clade.

- While all members of the phyla we’re considering this week are in the bilateria (have bilateral symmetry and three tissue layers) – they also differ drastically. From your perspective: I) which groups considered in this unit are the most similar and what connects them? II) Which groups are most distinct and what separates them? **The phyla group mentioned in this question is circled in redarrow_forwardQ30: Match the all parts to this question, the answer choices are shown in the picturearrow_forwardCreate 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. 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 1) and 2) only.

Note that some descriptions may not apply to any of the 4 species (in which case just write “none") and some descriptions may apply to multiple worms species (in which case write the letters of all applicable species). (A) Dirofilaria (heartworms) (B) Dracunculus (Guinea worm) (C) Ascaris (D) Hookworms 1. Life cycle includes only a single host 2. The infective stage is a free-living larva that can enter the skin directly 3. On target to become the first parasite-caused human disease to be eradicated 4. Has an arthropod intermediate host 5. Traditional treatment involves winding the female worm around a matchstick 6. Infections can be prevented by not defecating on soill improving sanitation of soil 7.

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_forward

There are many phyla within the animal Kingdom, and in this activity, you will explore these phyla by building a dichotomous key that will allow you to consider almost any animal and determine which phylum it belongs to. Part 1: Organizing information for the dichotomous key 1) List the 9 animal phyla of macroscopic (visible) animals: Porifera, Cnidaria, Platyhelminthes, Nemotoda, Annelida, Arthropoda, Mollusca, Echinodermata, and Chordata. 2) Use on-line or library resources of your choice, to gather information about these 9 phyla. a. Start by finding two example species per phylum to help tie into your previous knowledge about animal types. Write down these examples. b. Make a list of characteristics that you could use that would help you tell these 9 phyla apart. The final goal is to build a…arrow_forward
