A) Fossil evidence showing that the common ancestor of species A,B,and C had short wings and evidence that species A and B are sister species
B) Fossil evidence showing that the common ancestor of species A,B,and C had long wings and evidence that species A and B are sister species
C) DNA evidence showing that species A and C are sister species
D) DNA evidence showing that species B and C are sister species
E) Evidence showing that species A and B live in an environment that favors long wings,whereas species C lives in an environment that favors short wings
