Are there beneficial mutations?, I think so but my friend doesn't, I'd like to see hear examples if there are any.

I think melanism in leopards is but my friend denies it.

There are some beneficial mutations:

It depends of course what we consider to be beneficial, but if it is to increase chances of survival, as generally accepted, these would apply.

I'm also told schizophrenics don't suffer from allergies, but we don't remember where we heard that from.

People who are heterozygous for sickle-cell anemia cannot suffer from malaria. A person resistent to the bubonic plague cannot contract HIV (this is only seen in about 9% of Europeans, however).

mutations are mutations. the only thing that makes them beneficial is if it helps the organism survive so that it can reproduce and the gene can be passed on. a mutation in an organism could be beneficial in one environment and detrimental in another.
