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?
See attached. 1. Which pair of animals in numbers 1-3 belongs to a common ancestral group? Explain your answer.2. Fossils and anatomical records both provide pieces of evidence of evolution. How do you determine the age of fossils of an Aurorazhdarcho micronyx and an Archeopterix?
The phylogenetic tree in Exercise 1 above shows an outdated relationship between Brachiopoda, Bryozoa, and Mollusca.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

- Lab 10: Kingdom Animalia Introduction Animals all share some characteristics: 1) Multicellular 2) Heterotrophic 3) Their cells have no cell wall 4) At some time in their life they are motile. 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_forwardWhy are simpler structures considered ancestral when we study phylogeny? * 1 point Complex structures often evolve from simpler ones. Time element is a major consideration. The presence of a character state among some members of a lineage and an outgroup indicates that the character is ancestral.

- You have now studied three different types of anatomical structures. Homologous structures show individual variations on a common anatomical theme. These are seen in organisms that are closely related. 1. Give an example of a homologous structure from this activity: Analogous structures have very different anatomies but similar functions. These are seen in organismsthat are not necessarily closely related but live in similar environments and have similar adaptations. 2. Give an example of an analogous structure from this activity: Vestigial structures are anatomical remnants that were important in the organism's ancestors but are nolonger used in the same way. 3. Give an example of a vestigial structure from this activity:arrow_forwardL Gymnospermae 100 200 100 200 300 Amphibia 0 50 100 150 200 0 25 50 75 100 Aranea Diptera 50 100 150 50 100 150 200 250 50 100 150 200 250 050 100 150 200 Clade age (my) Clade age (my) Clade age (my) Clade age (my) Figure 3.
