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
Time
Based on the geographical distribution of the bats over time, which of the following is mostly true about the evolutionary
relationship of these species?
A.
Species 2 shares a more recent common ancestor with species X than with species w.
B. Species W shares a more recent common ancestor with species Y than with species X
C. Species X shares a more recent common ancestor with species Z than with species W

1. seamount a raised footwall block between normal fault creates this 2. syncline break between rocks where a hanging wall rises relative to a footwall 3. hot spring on rolling hills, this a dip between hills 4. volcanic neck created when a block with hanging walls slips down between normal faults 5. caldera underwater volcano that never reaches above sea level 6. horst natural hot water on earth's surface containing many minerals 7. graben underwater volcano whose top is eroded flat by waves 8. crater less than a mile in diameter; looks like a bowl at the top of a volcano 9. guyot magma that filled the central vent that remains after the volcano has eroded 10. reverse fault over 1 mile in diameter; looks like a bowl over a volcano
