Imagine this scenario: One hundred rock pocket mice, 99 with dark fur and one with light fur, are transported to a beach in Florida and released to reproduce and survive. Light fur gives a survival advantage of 50 percent. Approximately how many years would it take for the vast majority of the population to end up with light fur?
It is difficult to give an exact answer to this question, as it depends on a variety of factors such as the rate of reproduction, the rate of mutation, and the environmental conditions. However, it is likely that the process would take several generations, and it is estimated that it could take anywhere from 10 to 20 years for the majority of the population to end up with light fur.
