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 Biologists typically show these same relationships in a simple branching tree diagram called a cladogram. The cladogram summarizes the sequence in which selected traits first appeared, and indicates when particular combinations of traits gave rise to groups we recognize today as major groups, with those traits as their definitive hallmark. Start studying Cladogram - practice. Learn vocabulary, terms, and more with flashcards, games, and other study tools. The lancelet and lamprey does not have this trait. Location. Term. Amniotic egg. Definition. What feature separates a salamander from a turtle? Location. Term. Hair. Definition. The leopard is the only organism with this lancelet. Which group on the cladogram evolved first? salamander, turtle, leopard. List all the organisms shown in the diagram that have four walking legs. turtle and leopard. Which two organisms are closely related? (for this one you are going to want the question to be the definition and the term your answer) Learn with flashcards, games, and Cladistics compares ingroups and outgroups. An ingroup (lizard, rabbit and human in our example) is the group of taxa being analyzed in Figure 4.4.2.10 4.4.2. 10. An outgroup (lancelet, lamprey and fish in our example) is a species or group of species that diverged before the lineage containing the group (s) of interest. Lab: Creating a Cladogram Background: Cladistics is one of the newest trends in the modern classification of organisms. This method Materials: Pictures of lamprey, trout, caecilian, turtle, cat, gorilla, and human Procedure: 1. Make careful observations of the animals in the pictures you have been given.
