Through the phylogenetic tree of major groups of vertebrates provided below, answer the given table by numbering and naming each node in the diagram. Then list the names of each group and write down the shared characteristic(s) of it. You may add more rows if needed. Node Number (e.g. 1 - Gnasthostomata) Animal Group 1 Animal Group 2 Shared Characteristics of Animal Group 1 & 2
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)
In the phylogeny to the right, draw a box around the clade Sarcopterygii (lobe-finned fishes). Label it “A”. b. Draw a box around the sister group to Echinodermata. Label it “B”. c. Circle the node that corresponds to the most recent common ancestor of Actinopterygii and Chodrichthyes. Label it “C.”
Imagine that you are a marine biologist. As part of your exploration, you dredge up an unknown animal from the seafloor. Describe some of the characteristics you should look at to determine the phylum to which the creature should be assigned.
In the frog embryo, convergent extension elongates the notochord. Explain how the words convergent and extension apply to this process.
The __________ is the receiving chamber of the heart, which pumps blood to the __________, the pumping chamber of the heart. The optic nerves criss-cross the brain, connecting to each eye via the __________. Mammals are a member of the eutherian clade, indicating they have true __________.

Through the phylogenetic tree of major groups of vertebrates provided below, answer the given table by numbering each node (the point where branches intersect) in the diagram. Then list the names of each group and write down the shared characteristic(s) of it. You may add more rows if needed. Node Number Animal Group 1 Animal Group 2 Animal Group 1&2 Shared Characteristics
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.
Cnidarians (and ctenophores) are diploblastic animals. What is the fate of the ectodermal and endodermal cells in cnidarians? Answer this by keeping track of structures /Nssues /cells of “organs” that are derived from the ectoderm or from the endoderm or both and by which group/taxa. Is there a common pattern for all or are there variations?
Draw a phylogenythat accurately portrays the evolutionary relationships among the organisms listed. Each organism listed should be at the tip of a branch on the tree. Use the internet to discover what type of organisms they are, and refer to the textbook and course notes as you determine the relationships among these organisms. Label the phylogeny with each of the 6 species listed and write on the tree where the following derived traits evolved: specialized tissues, radial symmetry, bilateral symmetry, deuterostomy, protostomy, and ecdysozoan cuticle (the need for an animal to molt in order to grow).
