90 million years ago (mya), a single bat species existed on a landmass. That species served as a common ancestor of the four bat species now found in the region. The image below shows how the landmasses have changed over time and the current distribution of the bat species.
Based on the geographical distribution of the bats over time, which of the following is most likely true about the evolutionary relationship of these species?
A.
Species X shares a more recent common ancestor with species Z than with species W.
B.
Species W shares a more recent common ancestor with species Y than with species X.
C.
Species Z shares a more recent common ancestor with species X than with species W.
D.
Species Y shares a more recent common ancestor with species W than with species Z.
