Reading a Cladogram

A cladogram is a diagram used in cladistics which shows ancestral relations between organisms, to represent the evolutionary tree of life.

Use the diagram to the right to answer questions 1-4.

1. Which organism is most closely related to sponges? 2. Which organisms are the most closely related to flatworms, mollusks and annelids? 3. Which organism is the most distantly related to sponges? 4. Which organism would be the most closely related to roundworms?

Use the diagram to the left to answer questions 5-7. 5. Who is the closest human ancestor? 6. Which Primate is the most distantly related to humans? 7. Which primate branched off from chimpanzees?
