The mouse is a small rodent with a pointed nose, small ears, and a long, naked tail. It is one of the most common and widespread rodents in the world and is found in nearly every habitat, including urban areas. The mouse is an important model organism in biology and is used in research into genetics, physiology, and medicine.
The first mouse was invented in 1968 by Douglas Engelbart. The mouse was originally designed to be used with a computer. The first mouse was made out of wood and had one button.
