Town Mouse, Country Mouse: adaptation and adaptability in Mus domesticus (M. musculus domesticus)
Abstract The generally accepted idea that the house mouse is a single, world‐wide species which owes its success largely to commensalism with man is wrong. There are at least five European and two Asian species lumped together under the name Mus musculus , plus another fourteen Asian species in the...
