Not according to my son's public high school Biology teacher. As of last month, science teachers in PUBLIC high schools are STILL (after the 30+ years it's been since I was in high school) teaching that most mutations are harmful.
This statement, which is virtually always labeled as a *creationist lie* was taught , and still is being taught as science. If this has indeed changed, then the responsibility for getting the correct information out rests squarely on the shoulders of the scientific community, and they have apparently dropped the ball. Creationists can't be the ones blamed for perpetuating this one.
I may be incorrect in my assessment regarding the general trend of mutations. However, to counter the theory of evolution it must be demonstrated that mutations can never be beneficial.
