Spontaneous mutation is a term used to describe a sudden genetic change without an external cause. It is a common phenomenon in biology and genetics that can create genetic diversity over time, but it is also associated with various health issues. There are many different synonyms for spontaneous mutation, including random mutation, natural mutation, non-induced mutation, or genetic drift. Each of these terms implies a similar notion of a genetic change occurring without direct manipulation. These synonyms help scientists to better understand and investigate the impacts of spontaneous mutation on organisms and ecosystems.
