comment Have proteins been observed to come into existence through mutations and natural selection?
These are fascinating modifications of proteins. I was hoping for something more drastic than modified binding specificity and catalytic efficiency. Has there been a change in function from one reaction to a completely unrelated one?

@James I apologize for the poor quality of the original question. I was fresh off a heated debate when I asked this question. I have modified it to better reflect my ignorance seeking understanding.

Oncofusion is very similar to homologues, especially when there is not modification of function. Your link on "EWS-FLI1" explains that a virus causes a cancer by modifying gene regulation, which is a change in DNA sequence not Protein amino acid sequence. I don't see how your answer addresses a change in reaction catalyzed.

comment How do plant galls form?
I recently aquired, "“Britain’s Plant Galls, a Photographic Guide.” It expanded upon what you said about insects injecting growth hormones: Sawflies belong with the gall wasps in the order Hymenoptera. The female has a tiny saw-like ovipositor with which she cuts slits in plants prior to laying her eggs. She injects a stimulant when laying her eggs and the galls start to grow before the eggs hatch. Most sawfly galls are solid at first and usually contain a single larva that gradually hollows them out. Mature larvae of most species leave their galls before pupating – often in the soil.

This is an exciting field. I am very interested in the potential to avoid the immune system.

Any idea how far along the animal model viruses are?

@canadianer Any information will be appreciated. A category or specific type is what I had in mind.
