Mutation can serve up the raw variation that natural selection selects from, thus alleles are changed over time in populations of organisms; evolution.
Mutation, genetic drift and gene flow can all drive evolution to a degree and the last two, drift and flow, are especially powerful in small populations. But, the driver of adaptive change in all populations of organisms is natural selection.
Mutation is the cause of evolution. Mutation is what creates differences in individuals within a species, leading to diversion. Then "survival of the fittest" can occur.
A mutation is any change in the DNA. Mutations provide the genetic variation that evolution by natural selection needs to select from.
Mutation and Natural Selection

Together, genetic mutation and natural selection determine in what 'direction' evolution proceeds.

Mutation and Natural Selection
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.
No. One still selects individuals while populations evolve. Punctuate equilibrium is a theory at the taxa level and does not have anything to do with mutation, variation and selection at the individual level.
genetic drift, gene flow, mutation, natural selection and nonrandom mating ( sexual selection ).
Single individuals are naturally selected, but populations ( can be whole species ) evolve. Any mutation happening in the germ line of an individual will die with him. Only his progeny can inherit said mutation and evolve. Evolution is the change in allele frequency over time in a population of organisms.
