Tree Thinking Review
Draw a bracketed phylogenetic tree of the following groups on the next blank page:
• Peat Moss
• Capybara
•
Ostrich Fern
• Blobfish
• White Pine Tree
• Protists
• Escheria coli
•
Mexico Whiptail Lizard
•
Sunflower Sea Star
• Bold Jumping Spider
• T. Rex
•
Flatworm

After you draw your tree, label where the following traits would have evolved. Consider
that traits may have evolved more than one time.
• Chloroplasts
• Seeds
• Endosperm
• Flowers
• Vascular Tissue
• Mitochondria
Segmentation
• Central Nervous System
• Notochord
• Vertebrae
• Nucleus
• Membrane Bound Organelles
• Peptidoglycans

There are many phyla within the animal Kingdom, and in this activity, you will explore these phyla by building a dichotomous key that will allow you to consider almost any animal and determine which phylum it belongs to. Part 1: Organizing information for the dichotomous key 1) List the 9 animal phyla of macroscopic (visible) animals: Porifera, Cnidaria, Platyhelminthes, Nemotoda, Annelida, Arthropoda, Mollusca, Echinodermata, and Chordata. 2) Use on-line or library resources of your choice, to gather information about these 9 phyla. a. Start by finding two example species per phylum to help tie into your previous knowledge about animal types. Write down these examples. b. Make a list of characteristics that you could use that would help you tell these 9 phyla apart. The final goal is to build a…arrow_forward
- Hello, I need help with number 3 a, b, & c using the diagram below. Pls & thank you! 3. a) What features does the organism shown above have that indicate that it is our direct ancestor among the Cambrian fauna? 3. b) When the organism shown above was swimming in the Cambrian seas, it was very small compared to the apex predator (Anomalocaris), which was several feet long. What adaptations might the organism shown above have to evade predation by Anomalocaris? 3. c) A famous evolutionary biologist says that “everything in evolution is contingent”, which he explains means that events could always have turned out differently. Do you think that the survival of our direct ancestor is an example of a lucky accident that allowed the later evolution of vertebrates, including us? Why or why not? Photos reference: Futuyma, D.

Time element is a major consideration. The presence of a character state among some members of a lineage and an outgroup indicates that the character is ancestral.

- You have now studied three different types of anatomical structures. Homologous structures show individual variations on a common anatomical theme. These are seen in organisms that are closely related. 1. Give an example of a homologous structure from this activity: Analogous structures have very different anatomies but similar functions. These are seen in organismsthat are not necessarily closely related but live in similar environments and have similar adaptations. 2. Give an example of an analogous structure from this activity: Vestigial structures are anatomical remnants that were important in the organism's ancestors but are nolonger used in the same way. 3. Give an example of a vestigial structure from this activity:arrow_forwardMAKE CONNECTIONS Historically, annelids and arthropods were viewed as closely related because both havebody segmentation. Yet DNA sequence data indicatethat annelids belong to one clade (Lophotrochozoa) andarthropods to another (Ecdysozoa). Could traditionaland molecular hypotheses be tested by studyingthe Hox genes that control body segmentation (seeConcept 21.6)?

If a term appears in parentheses below the pair, both your answers must be related to that term (e.g. if the term says "structure" your answer must relate to anatomy). • Pseudocoelomate animal & coelomate animal Similarity Differencearrow_forward
- 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_forwardUse the image to answer the question.
