The proof you are talking about is keep on changing.Still it is theory not a fact or Law of evolution. Dont exaggerate as exaggeration while explaining a theory would not make it a fact.
If you have read the science journals , last week they were talking about "New Physical Laws" which will again change the whole scientific explanations so far we have.
