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?
It is likely that the four bat species evolved from a common ancestor on the original landmass and diverged into different species as the landmass separated into different regions.
