Oh yes, I certainly know that DISEASES are caused by mutations. Diseases and deformities and miseries galore are caused by mutations. This is one of the reasons why mutations hardly seem like an engine that could power life at all.
How can you know that for sure? How do you know that you not really seeing allelic shuffling or evidence of design? Seems to me like you are trying to eat your cake and have it.
Well, I know this because God wouldn't DESIGN in disease and death; It is the deterioration or disintegration of the design, the result of sin.
I've agreed that it's possible that beneficial mutations may play a part in the processes of life, but the evidence so far is not very convincing. Variations are merely CALLED mutations without any evidence whatever that they are in fact mutations. Whatever it would take to prove that they are truly novel, never existing before in the population, is what is needed.
Like I said. You're eating your cake and having it. Thanks for proving my point.
