Adventure World and Fun Park are 30 miles apart. Both amusement parks have thriving pigeon populations. People drop food throughout both parks, providing the main food source for the pigeons.
Adventure World has the more exciting rides, and Fun Park is forced to close when it is unable to bring in enough people to cover operating costs. Upon closing, wildlife from the surrounding areas begins to take over.
In terms of evolutionary change, what is likely to happen to the two pigeon populations in the future?
