Question

Species A and species B are shown on the same branch of a branching tree. Species C is shown on a separate branch. All three species came from a common ancestor. What can you state about the similarities of the DNA of species A, B, and C?

Answer 1

That would mean that species A, B, and C all came from one tree. Species A and B would be closer related, and also resembling more of each other. While species C would be also related to species A and B but just not as close to either one. 

So the answer would be: Species A and B would be most similar, while species C would be related to both species A and B but will have less similarities. <span />
