In Figure 2 a diagram shows how traits are shared (or not shared) in different generations. Based on the diagram: a. A, represents a plesiomorph trait. In how many generations is A shared (symplesiomorph)? b. C represents an apomorphictrait. What generations share C (synapomorphy)? c. E is considered an autapomorphic trait. Why do you think? d. What about B and D? How do we classify them?

a. A, represents a plesiomorph trait. In how many generations is A shared (symplesiomorph)?

b. C represents an apomorphictrait. What generations share C (synapomorphy)?

c. E is considered an autapomorphic trait. Why do you think?

d. What about B and D? How do we classify them?
