Step by step
Solved in 2 steps
- Draw a phylogeny of deuterostomes, indicating the mostlikely relationships among chordates, hemichordates, andechinoderms, with common examples of each groupGive the 5 synapomorphies of the organisms under Phylum Chordata.Order these groups in order of diversity : Phylum Porifera Phylum Cnidaria Phylum Platyhelmenthes Phylum Annelida Phylum Mollusca
- Make a cladogram that includes the following groups of fishes: chon-drosteans, elasmobranchs, hagfishes, holocephalans, lampreys, lung-fishes, teleosts. Add the following synapomorphies to the diagram: claspers, cranium, endochondral bone, fins with stout bones, jaws, keratinized teeth.Develop a KEY to the CLASSES of Phylum ECHINODERMATA: Asteroidea, Ophiuroidea,Echinoidea, Holothuroidea.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.”
