The bird flu virus is not evolving.
It's mutating. It's a virus that has been around for a long time and is changing slightly.
There are plenty of examples of mutation in biology which ARE observable.
Evolution is a separate matter. It is a theory.
Despite Darwin's title "Origin of the Species", no new species has been shown to originate from another.

I don't think you know the first thing about evolution. Evolution occurs through a series of mutations. If a mutation is beneficial to the survival of the species, it is more likely to be passed on and propagate.
And do you know the difference between a hypothesis and a theory? A hypothesis is basically a guess that's waiting to be tested thoroughly. It becomes a theory when it's been tested numerous times and there's wide scientific acceptance of its validity. In this context, "It's just a theory" is layman's talk for "I have no idea what I'm talking about."
Mutation - any change in the DNA of an organism...beneficial mutations may increase in the population due to natural selection...
Evolution - the gradual process of genetic change that occurs in populations of organisms...

Natural Selection = Evolution
