"If it does mutate it is nearly always a bad thing."

Not nearly but always a bad thing for the organism. When my wife was doing graduate work in geneitcs at the U of I, we visited Argon National Laboratory. This was in the 70's. At that time Argon Labs in corporation with many other labs had been trying to produce a beneficial mutation for amost 20 years and had completely failed. We have many examples of harmful mutations but no beneficial mutations.
This further confirms that DNA material is fixed as far as developing greater complexity. The only change that is observed in the DNA is a degeneration or harmful mutations. This is in agreement with the 2nd. Law of Thermodynamics--a tendency towards less complexity and less energy.

<< The fact that a found species is extinct does not lead to the conclusion it came before another similar species. They both could as easily have started at the same time >>

All you need to show the world is one example of a pre-Cambrian large mammal fossil to make history. If your statement is correct they should be all over the place. Happy hunting.
