Textbook Question
Chapter 27, Problem 8TYU
FOCUS ON EVOLUTION
In Figure 27.29, circle the smallest monophyletic group that includes dinosaurs. Explain your answer and list the taxa that are in this clade. Knowing that birds are endothermic and crocodiles are ectothermic, can you use phylogenetic bracketing (see Concept 20.3) to predict whether dinosaurs other than birds are ectothermic or endothermic? Explain.

Your age-dating put the age of the rocks you are examining in the early Devonian period. Because of this, you suspect that the vertebrate remains you found might belong to some of the
earliest tetrapods (four-legged animals including land vertebrates) to walk the Earth. Examine the cladogram below. What is the sister group to the land vertebrates?
Lampreys
Sharks
Lungfish
Land vertebrates
Tetrapoda
Choanata
Fingers and toes
Osteichthyes
Choanae
Gnathostomata
Bony ribs and shoulder girdie
Vertobrata
Jaws

The following four line drawings are reconstructions of invertebrate fossil. Using your knowledge of the extant invertebrate phyla, please indicate which phylum this species mostly likely belongs to. Support your conclusion by connecting the morphological characteristics of the fossil species with the distinguishing characteristics of the phylum.
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.

- 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.arrow_forwardThe taxon Crocodilia includes crocodiles, Aves includes birds, and Squamata includes snakes and lizards. If we think of Crocodilia and Squamata as reptiles, what kind of phylogenetic group do they form?
