Living things that are well adapted to their environment survive and reproduce. Those that are not well adapted don’t survive an
d reproduce. An adaptation is any characteristic that increases fitness, which is defined as the ability to survive and reproduce. What characteristic of the mice is an adaptation that increased their fitness?
Mice are able to reproduce monthly once they reach the age of maturity. This adaptation increased their fitness because it allows for many chances to pass on genetics from one generation to the next. Some studies have also shown that mice developed a tan fur which probably helps with camouflage, contributing to their longevity as opposed to black fur.
