The phylogenetic tree in Exercise 1 above shows an outdated relationship between Brachiopoda, Bryozoa, and Mollusca.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
1. Where do Loricifera fit into a phylogeny? Explain with an image. 2. What is a body plan of Loricifera (ex: deuterostomate? acoelomate?) 3. What is the support of Loricifera?
Which of the following most accurately reflects current understanding of phylogenetic relationships in the clade, Ecdysozoa? O Insects are more closely related to barnacles than to scorpions. Nematode worms are more closely related to annelid worms than to millipedes and centipedes. Decapods and myriapods are each other's closest relatives. Pancrustacea includes beetles, crabs, and horseshoe crabs.
While collecting specimens, a marine biologist finds a sessile Cnidarian. The medusas that bud from it swim by contracting a ring of muscle in their bells. To which class does this specimen belong? Class Hydrozoa Class Cubozoa Class Scyphozoa Class Anthozoa

Please complete the following (abbreviated) cladogram of Metazoa, labeling tips, nodes and synapomorphies by using the following word bank: Choanoflagellates multicellularity triploblasty Arthropoda Lepidosauria Cnidaria Bilateria Deuterostomia Ecdysozoa radial cleavage Porifera Mammalia Nematoda 2. Use the tree above to answer the following questions: Name the monophyletic group that is most closely related to Deuterostomia. b. Circle the monophyletic group Animalia (Metazoa). Circle the MRCA of Nematoda and Choanoflagellates. d. Write another name (many possibilities, not listed in the word bank) for the MRCA of Mammalia and Lepidosauria, a. C. 工
