My use of the term mutation was vague. I was referring to spontaneous random mutations in the parent that are passed on the offspring. I was making the point that this is not some kind of totally new organism. It's a flu virus that has different genetic traits and geometry than its predecessor. It has picked up some virulent traits, changing it into a more harmful variant.
Flu viruses change every year, primarily in Southeast Asia where pigs, ducks, and people live in very close quarters. This may be a form of mutation, but it has not resulted in a new species. I think that puts it in the camp of slight variant, and not of evolved species.
