1. Spontaneous mutation
A mutation which occurs by itself without first being affected by a mutagen , for example during the process of DNA replication . Spontaneous mutations arise at a remarkably constant rate. The rate that spontaneous mutations arise has been used as an evolutionary clock to estimate how closely related two (or more) separate species are to each other.
