Homework Answers
3rd option
Species C is equally related to Z and T because C is sharing same ancestor with Z and T. So first statement is incorrect.
Second statement is incorrect because species X is more closely related to species E as compared to species Z.
Third statement is correct because species B and species Z that share a more recent common ancestor as compared to species B and species X.
Fourth option is incorrect because species B is not an ancestor. It is a living species.
Fifth statement is incorrect because species A is equally related to species X and species B.
Please rate high.
