Mutations occur randomly as a result of errors during DNA replication or the effects of external agents such as chemicals or radiation. While certain mutations may provide an advantage in certain environments, they do not occur to fulfill a specific need or purpose. The frequency of mutations varies depending on a number of factors, but it is not limited to occurring in only one out of 100 people.
