In the Mollusca phylogenetic tree below, circle the node that corresponds to the latest common ancestor of Scaphopoda and Gastropoda. Label it “A” In the same tree, circle the clade that includes Bivalvia and Cephalopoda. Label it “B”.
Imagine you come across a small worm. How can you determine whether it is a class Hirudinida or a turbellarian? Give two distinct differences between the two without naming the same structure/invisible features of each animal (e.g animal x has 2 wings, animal y has 4 wings are not distinct differences)
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.
Sponges (Phylum Porifera) are the basal taxon to animals and were once thought to belong to plants. 1) Identify three characteristics that distinguish sponges from plants. 2) Identify three characteristics (present or absent) that distinguish sponges from other animal taxa.
There is current controversy about which group is sister to the rest of the animals. Which two of the following groups are the potential sister groups to all the other animals? a. Ctenophores b. Cnidarians c. Porifera d. Both a. and b. e. Both a. and c.
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 phylogenetic diagram showing only the interrelationships among the following clades: Tetrapoda, Lissamphibia, Amniota, Diapsida, Synapsida, Turtles, Archosauria
Molecular techniques like DNA sequencing led to a restructuring of morphologically-based taxonomy and phylogeny such that A)annelids and arthropods were designated as closely related. B)echinoderms and chordates were placed in entirely different clades. C)Bilateria was designated as a monophyletic group. D)Ecdysozoa and Lophotrochozoa were designated as clades. E)rotifers and nematodes were designated as closely related.
Consider clades Bilateria, Lophotrochozoa, Metazoa, Chordata,Ecdysozoa, Eumetazoa, and Deuterostomia. List the clades to whichhumans belong in order from the most to the least inclusive clade.
Give at least (3) body structures that are salient among these groups of animals: Protozoans Poriferan Cnidarians
Construct a character matrix by making observations on the different features of the following group of invertebrates. On the table, write 1 if the character is present in (or exhibited by) the group; 0 if absent (or is not exhibited). Group of organisms Segmentation Coelom Jointed appendages Cephalization Tissues Radial symmetry Porifera Arthropods Cnidarians Nematodes Annelids Input the characters in the pre-made cladogramthat is provided for you. Also, write in the empty boxes the correct group of organisms to show relationships. One character and one group of organism is done for you.
Suppose you discover a new species of animal that does not have body segments, but is triploblastic, coelomate, and cephalized. Under the molecular phylogenetic scheme, you would allocate it to which phylum? A)Platyhelminthes. B)Arthropoda. C)Nematoda. D)Mollusca. E)Echinodermata.
