It would appear that the questioner is under the mistaken impression that beneficial mutations are a problem for creationists. Some creationists make this unfortunate error. The mutations Q&A section of our Web site clearly teaches that the issue is not whether the mutation is beneficial but if it adds new genetic information (specified complexity). So it would have been clear that the A-I Milano mutation is not evidence for microbe-to-man evolution
No point reading after this. This is what's known as "squirreling the subject." Increased complexity is not a requirement of evolution, except in the minds of creationists.
