2. Chordate evolution The diagram shown here is sometimes referred to as a cladogram. It shows the relationship between different groups of organisms with the same s of characteristics, called clades, and it shows how these groups evolved from shared ancestors over time. The label "Ancestral Chordate" at the bot of the cladogram indicates an organism that no longer exists today but that all living chordates evolved from. The movement of the branches from t bottom of the diagram to the top of the diagram represents the passage of time moving forward. A split in the tree occurs each time a new trait developed that separated one group from another. Select the correct label to complete the diagram.
