Mark Yourself Question
  1. Grab a piece of paper and try this problem yourself.
  2. When you're done, check the "I have answered this question" box below.
  3. View the solution and report whether you got it right or wrong.

The tree above is one possible phylogeny of the Homo clade. Use this diagram to answer the following questions

1. What does Australopithecus africanus do for this tree?

2. What is happening on the tree where the blue circle is located?

3. There are 2 character state changes on this tree. What are the apomorphic and plesiomorphic states for each of these characters?

4. Identify all the monophyletic groups on this tree that are held together by synapomorphies, name the synapomorphy.
