- View the preserved arthropod specimens available. There will be at least one example of each lineage group discussed on the website but not all of the specimens may be available. Use the table on the next page to organize your observations. Specialized segments Name of Lineage Exoskeleton? Jointed specimen Formica rufa appendages? Pandinus imperatur Rhinotia hemistictus Eurytides marcellus Ranina raninaillustrates four key characters ofchordates: a notochord; a dorsal, hollow nerve cord; pharyngeal slits or clefts; and a muscular, post-anal tail.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.
- Use the cladogram below to answer the question that follows. Arachnata Trilobita Chelicerata Arthropoda Crustacea Mandibulata Myriapoda Insecta The closest common ancestor of Trilobita and Chelicerata is O Mandibulata O Insecta O ARthropoda O ArachnataWhich organism is most related to the amphibians on this cladogram?Make a cladogram that includes the following groups of fishes: chon-drosteans, elasmobranchs, hagfishes, holocephalans, lampreys, lung-fishes, teleosts. Add the following synapomorphies to the diagram: claspers, cranium, endochondral bone, fins with stout bones, jaws, keratinized teeth.
- which characteristics would describe Collembola? check all that apply Abdominal appendage present No abdominal appendage Mouthparts hidden within head Mandibulate mouthparts Antennae with more than 8 segments Antennae with less than 8 segments No prolegs on the abdomen No visible evidence of wings Wings present 6 legsIn the phylogeny to the right, draw a box around the clade Sarcopterygii (lobe-finned fishes). Label it “A”. b. Draw a box around the sister group to Echinodermata. Label it “B”. c. Circle the node that corresponds to the most recent common ancestor of Actinopterygii and Chodrichthyes. Label it “C.”Draw a cladogram of the 2 Classes of Annelida, including the 2 Families under Order Clittelata and add 1 outlier from another Phylum. Make sure to add the derived traits/characteristics in your cladogram (give at least 1 trait).
- Fill out the accompanying table and submit on Caxpas, contrasting the key features of each class of echinoderms. Qphuraidea Holothuroidea Classs Shape of body Asteroidea Echinoidea Ambulacral groovesDraw a cladogram for the animals: Amphioxus; Lamprey; an osteostracan( derived ostracoderm); Reef shark;African lungfish and cichlid ( teleost fish) and label the cladogram with the following clades and characters Clade:Chordata; Vertebrata; Gnathostomata; Chondrichthyes 5. Osteichthyes (bony fishes); Sarcopterygii (lobe-finned fishes) and Actinopterygii (ray-finned fishes) Characters: Notochord; Muscular pharynx; Dermal bone; Pectoral fins • Jaw; Pelvic fins; Endochondral bone; Lobed fins and 7 clusters of Hox genesHemichordates are a sister group to the chordates. This group contains organisms called acorn worms. They don’t have all of the chordate characteristics - just some. Question: Which ones are synapomorphies of the chordates and which ones are symplesiomorphies based on this cladogram?
