The House Mouse is a non-native commensal rodent originating in Central Asia that has spread globally alongside human civilizations. It is one of the world's most studied mammals, serving as the primary model organism in genetics and biomedical research. House mice reproduce explosively—up to ten litters per year—and populations can reach extraordinary densities in grain-storage facilities.
