Before the 1700s, the white-footed mouse, permyscus leucopus, lived in
the rural woodlands that once covered the area now known as new york
city. as the city expanded, mouse populations have remained in these
urban areas. other mouse populations have also continued to live in the
rural areas around new york city. recent studies show that mice from
rural populations have longer teeth than mice from urban populations.
which statement best explains the observation that rural mouse
populations have longer teeth than urban mouse populations?
o urban mouse populations need much more food than rural mouse populations
food in rural areas requires more chewing, so mice with longer teeth are better
suited for rural areas.
o food in rural areas requires less chewing, so mice with longer teeth are better
suited for rural areas.
o urban mouse populations need much less food than rural mouse populations
