adapt to a variety of habitats and food sources
fill niches usually occupied by mammals
occupy habitats that have no other life-forms
Two populations of mice living in the same forest are separated by a large water-filled ditch. After a rainstorm, flooding brings several mice from one population to the other population.

The offspring will be forced to leave the second population.
The offspring will be genetically identical to their parent from the first population.
