Textbook Question
Chapter 33, Problem 1SYK
Use the following evolutionary tree (which is based on molecular evidence) to help you review the diversity of animal phyla. Label clades a. through e. Then identify each phylum and list some key characteristics and common examples of each. The small sketches should help you identify the phyla. (Note that a sketch of a brachiopod represents the two lophophorate phyla.)

Make a table separating the animals based on the physical properties such as:
I. Presence or absence of a backbone II. Ability to breathe in air or water III. Cold or warm blooded IV. Carnivore, herbivore, or omnivore V. Presence or absence of hair/fur VI. Any other external structure such as horns
After that, construct a phylogenetic tree (example is on the picture I uploaded)
Draw a phylogenetic tree depicting our current understanding of the animal phylogeny. Include the major groups of animals at the tips of your tree: Deuterostomia, Protostomia, Lophotrochozoa, Ecdysozoa, Porifera, and Cnidaria. Additionally, label the common ancestor of all animals, indicate which groups are considered invertebrates, and indicate where the vertebrates fit within the phylogeny. Write on your tree where the following characteristics arose as evolutionary innovations: multicellularity, true tissues, radial and bilateral symmetry, animals with 2 germ layers and animals with 3 germ layers.
You are a scientist trying to determine the relationship between the organisms below. On a
separate sheet of paper create a cladogram that represents how these animals are related.
the words below in bold, must be used on your cladogram
1. Divide the animals into two groups depending on if they possess vertebrae.
2. Divide the vertebrates into groups according whether they have an amniotic egg or not.
(Hint: keep the animals who give live birth with the amniotic egg animals.)
3. Divide those who have amniotic eggs according to the presence of an exoskeleton.
4. Divide those with endoskeleton according to whether or not they give live birth.
5. Divide those with live birth depending on if they possess opposable thumbs.
6. Return to your invertebrates. Divide them according to the presence of an exoskeleton.
7. Divide those with exoskeletons according to whether they possess wings.
