Mutation
From Wikipedia, a free encyclopedia written in simple English for easy reading.
In biology, a mutation is a change in the genetic material (usually DNA or RNA) of a living being.
Mutations can happen for a lot of different reasons. It can happen because of errors during cell division, because of radiation, chemicals or all on its own.
Mutation, together with natural selection, is an important part of the theory of evolution.
Some mutations can be passed on to the being's offspring, and other mutations cannot.
