If wolves will not cross a highway what type of isolating me

Solution

Answer:

If wolves do not cross a highway, the highway may be considered as a geographical barrier and favour conditions for the formation of allopatric species (when populations of the same species get isolated due to geographical separation that prevents interbreeding).

Example: Formation of new squirrel species after the formation of grand canyon. Due to this geographical isolation, the north and south species cannot interbreed.
