We take a pair of metaphorical scissors to the tree below cutting it at the branch where the "X" is. We conclude that:
A) A, B, C, D, plus E is a monophyletic group because they have a common ancestor shared by all 5 taxa.
B) F plus G does not form a monophyletic group because A, B, C, D, and E are left behind
C) A,B,C, D, and E are a monophyletic group nested within ABCDEFG.
D) None of these answers are correct.
