Look at the images below. Which two organisms do you think are most closely related? I think that the Deer and the Turtle are more closely related. Worm Deer Turtle 2. Why do you think so? I think that they are more closely related because they are both vertebrates compared to the worm which is an invertebrate. 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.
