Can the genetic mutations from older fathers accelerate physical and intelligence increase consistent with genetic mutations and evolution of the human species?

Doubtful. Aside from a fluke copying error the mutations in germ line cells of the older father are, statistically, much more likely to be deleterious in nature, swamping any beneficial mutations along for the ride.

How does chance play a role in evolution?
Evolution is caused by adaptations (favorable traits) that sometimes come from mutations. Mutations happen by chance, and this is how chance plays a role in evolution.
Why do mutations that occur in the skin or nervous system tend to have little effect on the evolution of a species?
Most mutations that occur have a neutral effect, or none at all, so they would not affect evolution. Organisms with mutations that cause detrimental impact typically will not survive; therefore, they will not reproduce, and the mutation will not be passed on, so the species will not be affected overall. Beneficial mutations are typically the only mutations that will affect an organism's posterity and the evolution of its species, but good mutations are very rare. This is why most mutations have little effect on the evolution of a species.

Is 'mutations are beneficial to organisms' a true statement about mutations?
Usually mutations have deleterious effects to the organism, but occasionally there are beneficial mutations. Such mutations drive evolution.
Are all mutation harmful?
Mutations that succeed [are beneficial] provide Evolution, so not at all.
Why are mutations are important for evolution?
Mutations serve up the variations in organisms to natural selection. The reproductively successful variations pass on these successful traits to progeny and allele frequencies change because of this and this is evolution.
Mutations such as polyploidy and crossing over provide the genetic basis for?

Is evolution good or bad?
Genetic mutations can be good or bad, but evolution refers specifically to those mutations that make an organism better able to survive and to perpetuate their species, which makes them generally a good thing.
What are the mechanisms of evolution?
There are several mechanisms for evolution. The first (and most important) being natural selection, which plays off random mutations. Genetic drift is also another important aspect of evolution. EDIT: It depends on what you mean by "mechanism." Mutations are thought to be the mechanism that causes the change in DNA, then natural selection and Gentic drift take over. Unfortunately, mutations do not hold up and evolution is ultimately left without a mechanism.

How can genetic mutations support macro-evolution?
Mutations in an individuals germ line can be passed into progeny and if these mutations are beneficial then the allele frequency in the individuals population can change which is evolution. Over time and with many beneficial mutations against a favorable environment a population, or populations, most often geographically isolated, can change alleles so much that the two split populations can no longer interbreed and you have a new species; macro-evolution.
