A mutation is any change in the DNA.
Mutations provide the genetic variation that evolution by natural selection needs to select from.
No, a beneficial mutation may not always be considered beneficial in the context of evolution because its effects can change over time or in different environments.
For a mutation to affect evolution, it must occur in the DNA of reproductive cells (sperm or egg cells) so that it can be passed on to offspring. Mutations that occur in somatic cells (non-reproductive cells) do not directly impact evolution as they are not inherited by future generations.

Hugo de Vries is the one who proposed theory of mutation . He said 'Mutation are discontinuous variations. These are due to changes in chromosomes, genes and DNA and may or may not be inherited.'.
Any change in the sequence of DNA nucleotides is called mutation.
Without mutation there can be no evolution. Without evolution there can be no speciation.
The mutation theory is basically stating that mutation is one of the major factors that cause evolution. The mutation has to be a beneficial mutation, meaning that it has to help the survival of the organism that got the mutation. The mutation causes knew genes and diversity which can spread quickly throughout a population and eventually change the frequency of alleles (causes mutation) Remember the mutation has to be beneficial to the survival of the organism.

A mutation is any change in the DNA. Mutations provide the genetic variation that evolution by natural selection needs to select from.
mutation brings about variation which is the basis of evolution and the two types of variation are heritable and non-heritable
Cell mutation
Mutation and natural selection.
Together, genetic mutation and natural selection determine in what 'direction' evolution proceeds.
