I think that what Phreak is trying to point out is that Flu is continually evolving and changing, visually, and within a short time frame. These are not different Bacteria, these are the same Bacteria changing, not conciously I might add, it is merely the axiom of 'survival of the fittest'. That does not mean things evolve to be 'fit to survive' it just means that millions of tiny mutations take place and the ones that are lucky enough to change in the right way at the time are the ones that survive.
This could be defined as 'Micro Evolution' which is only one of the 6 points mentioned, but what the writer of the website fails to understand is that the bigger the change, the longer it takes. And also fails to understand that we do NOT take the other 5 for granted and that it is HE who is conciously dividing the types of evolution up, to me they are just several levels of the same thing. The cells in our own bodies are mutating constantly, when it goes wrong you get such things as Cancer. So to ask someone for 'Hard evidence' makes me wonder what he wants, a film of a frog evolving into an elephant perhaps?
I have stated this before, but as an evolutionist, I can say that man was once far more primitive millions of years ago, until his brain evolved, my evidence is primitive cave drawings, stone tools etc. Carbon dating etc helps back up my claim.
A creationist will believe otherwise, and they are perfectly entitled to, but when I ask about the stone tools and cave drawings, they were apparently put there to test my faith.
Well.... it's tested

We may not be 100% right about how evolution works, but in my own opinion, we have a lot more evidence for evolution than creation
