What do mice have that no other animal has?

Mice possess a unique combination of genetic traits and physiological characteristics that allow them to serve as model organisms in scientific research. Notably, the mouse genome shares a significant degree of similarity with the human genome, making them invaluable for studying genetics, disease, and drug development. Additionally, mice have specific behavioral and social traits that are distinct, such as their ability to adapt to a variety of environments and their complex social structures. While many animals may share some traits, the combination and application of these traits in research contexts are particularly unique to mice.
