I think I understood what you mean. Perhaps then the original
question can be : Is there species which where placed in such
ecological niche in such selection pressure condition so that
not much mutation can be fixed?
Do you have any idea of an ecological niche or organism
that will fit this question?
Well, if I could ask the question, I can't answer ;-).
