I've never disagreed that life changes. My understanding is that when the changes occur, it is loss (or corruption) of information in the Gene pool. Some times this might have a
temporary benefit - but in the end the information passed on has decayed / deteoriated - instead of being enhanced.

This is simply incorrect. Many of the articles I pointed you to demonstrated mutations which lead to new function, hence INCREASED (enhanced) genetic content of that species. Plus, you have to understand that many mutations will dramatically increase the amount of DNA in an organism - insertional mutation and duplication mutations being examples of that.

This once again goes with my understanding. You make call them new species of flies. Ok - as discussed above, what someone calls a species may be different from another. They're still flies.
But they are a different species. If what you think is needed to prove evolution actually occurred (i.e. a fly giving birth to a cat) it would actually be a
direct disproof of evolution. Evolutionary theory states, quite explicitly, that evolution occurs via descent my modification. What you are suggesting would have to happen to "prove" evolution would actually disprove the theory - a rapid and immediate changes in the overall form of the organism would disprove, rather then prove, the theory.

Further more - they have lost ability - not gained it. This agrees with the bible interpertation of a 'curse' on the universe - that things will contine to decay, and not the other way around.
And what exactly have they lost? They still have all of the characteristics of flys; they simply cannot breed with each other. But everything else works as it did before.

Seriously though - here's another example of mutation (as described by the webpages I found). The ant in this case has legs growing out of its head where the antenna were. This does not show new information being inserted into the structure of the ant - instead it's a corruption of information (double up of the 'leg' information being placed where the antenna are).
That is not entirely true. The information for the antenna is still there; what has happened is that where those genes (and the genes for legs) gets turned on has been changed. The original information is still there.
This is actually how most major structural changes occur. For example, the biggest difference between humans and chimps is how long the genes which regulate brain growth are active - in humans the brain continues to grow long after the brain of the chimp has. So we get bigger brains, and hence are smarter. But the genes behind that are pretty much the same.
