But they have to occur at the right time in combination with a lightening strike, etc.

But in all cases, it is STILL HIV, right?? I.e. no evolution occurred - adaptation, variability of a species yes - but not evolution. No new "creature" was created.

Yes - punctuated equilibrium says it happened in spurts

Or just assert that it DOES fit when some get frustrated - instead of considering all the evidence.
