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.
Create a body plan table (Insert → Add Table) for the following animal phyla: Porifera, Cnidaria, Platyhelminthes, Mollusca, Annelida, Nematoda, Arthropoda, Echinodermata, and Chordata. Describe each phylum by identifying the following body plan features.
1) Symmetry: Asymmetrical, Radial, or Bilateral
2) Tissue type: Parazoa, Eumetazoa (diploblastic), or Eumetazoa (triploblastic)
3) Body cavity (if triploblastic): Acoelomate, Psuedocoelomate, or Coelomate
4) Developmental mode (if Coelomate): Protostome or Dueuterostome
Note: Depending on the body plan, features 3 & 4 may not apply to specific phyla.
* Please answer 1) and 2) only. Reposting question for other two to be answered.
. In the space below draw a phylogenetic tree showing the inter-relationships among the following clades: Protostomia, Arthropoda, Mollusca, Cnidaria, Echinodermata, Crinoidea, Blastoidea, Asteroidea, Ophiuroidea, and Echinoidea.

- Squirrel Monkey and Human Skeletons Examine the skeletons of both the squirrel monkey and human that are located in the classroom. Humans and squirrel monkeys are closely related as is apparent if we compare the classification of humans to squirrel monkeys.

At what category does the classification between the two first differ?arrow_forwardAs we have discussed in class, phylogenies are hypotheses, and can therefore change over time with new evidence. Relatively recent and strong molecular evidence (that we did not discuss in class) suggests that all members of the Subphylum Hexapoda are derived from a common ancestor within the Subphylum Crustacea, as in the cladogram shown below. Given this new information, answer the question below. Note: Don't panic. Some of the names of these groups are new to you (Copepoda, Malacostraca, and Remipedia are all classes or subclasses within the Subphylum Crustacea), but this will not affect your ability to answer this question. Myriapoda Copepoda (Crustacea) Malacostraca (Crustacea) Hexapoda Remipedia (Crustacea) If we insisted that all groups must be categorized and named so that taxonomic ranks/names always include a single common ancestor and all of its descendants, how would this new evidence change our definition of a hexapod?

What does this finding suggest? Group of answer choices The lophotrochozoans are monophyletic. The protostomes are a paraphyletic group. Division of these two groups occurred after the protostome developmental sequence appeared. These two subgroups have a common ancestor that was a deuterostome.arrow_forwardConstruct a character matrix by making observations on the different features of the following group of invertebrates.
