You may find it useful to complete a data matrix to help you see patterns in the traits. Remember to indicate what your traits are and add more rows as needed for additional objects. Trait 1: Circular Trait 2: Two Dots Trait 3: Four Dots Trait 4: Dark Blue Trait 5: Medium Blue Trait 6: Light Blue Trait 7: Large Object 1 Yes Yes No No No Yes No Object 2 Yes No Yes Yes No No Yes Object 3 Yes Yes No No Yes No No Object 4 Yes No Yes No Yes No No Object 5 Yes Yes No Yes No No Yes Object 1: Object 2:Object 3:Object 4:Object 5:Exercise 4 Work with a small group or alone to complete this exercise. The second step of classification is using homologous traits to determine the relationships between organisms. Based on the traits you identified in Exercise 3, it should now be possible to group some of the objects together. Objects that share a derived trait are related to each other, and they should be grouped together. Objects that share multiple shared derived traits are really closely related and should be subgroups within larger, related groups. Draw your groups here:
Exercise 5Work with a small group or alone to complete this exercise. The final step in classification is to diagram the relationships you have identified. Using the groups you made in Exercise 4, identify the nested relationships between the objects. Consider which objects are most closely related, and what object or objects are the next most closely related. Draw the cladogram of these relationships in the space below. Show which objects possess which traits by labeling your cladogram with the traits you used (as in Figure 9.8).
Chapter 10 Exercise 1 Work with a small group or alone to complete this exercise. Use the mystery mammals provided by your instructor (or depicted in the lab Appendix) to complete the chart below. Identify whether the mystery mammal is a primate and list one trait that helped you make this identification. Primate (Yes or No?)
