Respond to the questions and prompts in the orange boxes. Vocabulary: adaptation, amino acid, amnion, artiodactyla, bipedal, clade, cladistics, cladogram, convergent evolution, evolution, flower, mammary glands, molecular, morphological, multicellular, parsimony, sagittal crest, phloem, selenodont teeth, SNP, xylem Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. Look at the images below. Which two organisms do you think are most closely related? 2. Why do you think so? Gizmo Warm-up Cladistics is a method of hypothesizing the evolutionary relationships between species. A cladogram is a branching diagram that illustrates these relationships. For example, the cladogram on the right shows that deer are more closely related to turtles than to worms. In the Cladograms Gizmo, you will use morphological (physical characteristics) and molecular data to create cladograms. To begin, make sure Plants is selected for the Organism group and Morphological is selected for the Data type. Click on one of the characteristics to the left of the table on the TABLE tab. Information about the characteristic will be shown on the ORGANISM tab. Using the information on the ORGANISM tab, describe each of the characteristics below. ● Xylem and phloem: Xylem and phloem are tissues in plants that transport water and solutes up the plant (xylem) and food down the plant (phloem). ● Flowers: A flower is the part of a plant containing The deer and the turtle are most closely related. Worm Deer Turtle They are both quadrupeds and have tails. They are also both vertebrates while the worm is an invertebrate. They share similar morphological features that were most likely derived from a common ancestor.
