The process described in the scenario is genetic drift. Genetic drift refers to the random changes in allele frequencies in a population due to chance events, especially in smaller populations. In this case, the shorter tail trait was passed down due to luck, rather than being favored by natural selection.
Consider the following scenario:
An animal is born with a shorter tail. This makes no difference to its ability to survive or reproduce, but as a result of pure luck, the animal survives, reproduces, and passes its shorter tail down to its offspring. Over time, the species develops a shorter tail.
