Answer:
Which of these is the extant (that is, living) species most closely related to species X? c. V
Explanation:
These refers to the following evolutionary tree. The species that are most closely related to species X, are species V because they shared a common ancestor with X most recently. In the evolutionary tree whose horizontal axis represents time (present time is on the far right) and whose vertical axis represents morphological change, a single clade (i.e., a group of species that share a common ancestor) can exhibit both gradualism and punctuated equilibrium.
