Worm-like animals 4. Arthropods 5. Chordates and the vertebrates M3 Animals | 1/5 Zoology 1. Current eukaryote phylogeny with Animals Animals are nested in Opisthokonta with Fungi includes plants includes (a Kingdom) animals, fungi (2 Kingdoms) Molecular phylogeny from Burki et al. (2020) M3 Animals | 1/5 Zoology 2. Defining animals All animals Are multicellular Do not have chloroplasts Must consume organic material for nutrients All have one common origin "Protist"-like Formed colonies Cell specialization into tissues M3 Animals | 1/5 Zoology 3. Classifying animals Lineages vary in: body symmetry tissues presence of a body cavity (coelom) body segmentation M3 Animals | 1/5 Zoology 4. Lineages vary in body symmetry Asymmetry Radial Symmetry Bilateral Symmetry M3 Animals | 1/5 Zoology M3 Animals | 1/5 Zoology M3 Animals | 1/5 Zoology M3 Animals | 1/5 Zoology M3 Animals | 1/5 Zoology 5. Lineages vary in tissue specialization M3 Animals | 1/5 Zoology 6. Lineages vary in tissue specialization Tissues have specialized functions: Nervous: transmit nerve impulses Muscle: locomotion to movements within the body itself Connective: transport and structural support (blood and bone) Epithelial: covers internal and external surfaces of organs and external surface of the body M3 Animals | 1/5 Zoology 7. Lineages vary in having a body cavity (coelom) Some linages have an internal body cavity called a coelom Lines between the digestive system and body wall Filled with fluid and houses organs and circulatory system M3 Animals | 1/5 Zoology 8.
