I see. Kinda curious though, why would it have to be a certain extent to be considered evolution? Isn't that just stacked mutations? It seems silly to label it differently based on degree of change, if the change in itself is the process. I can see why some wouldn't want to call it mass mutation (leaves a less then desirable mental image I am sure) so why not call it simply evolution regardless of degree of change? That would also help stress that evolution doesn't work towards to higher goal end development, simply occurs, be it good or bad, with only the passing of the traits as markers if the trait was effective or not at helping the species adapt.
Well, since it isn't 3 a.m right now, I'll be able to explain it more effectively.
Genetic mutations in animals is passed on through reproduction, which theoretically increases the chances of more mutation, esp. if it's with another mutated animal. This results in physical changes that are passed on via that most enjoyable act.
A virus reproduces asexually through mitosis, thus the genetic change would have to occur on a much smaller level.
Alternately, if you have 10 monkeys and 10 HIV cells: 3 monkeys have the mutation, but that's all throughout their genes. 3 of the HIV cells have it, but they just divide. So it really just comes down to names and numbers.
