Hello doseofreality,
If you will, "micro-evolution" is the exercise of an adaptation mechanism already built-in and operational in the life-from, so no, that is not a violation of physics, but no sequence of allowable changes can be construed into an unallowable change. A bird has built-in adaptation mechanism which allow it some amount of adaptation to its environment, but these adaptation mechanism do not allow the bird to change into a horse, worm, or tree; it will always remain the kind of bird it is.
As far as the scientific community in general, they are people, and most people do not want to admit there is a God, for this then means that there are moral absolutes and there is One to whom all must give account. So, as Paul discusses in Romans chapter one, they suppress their knowledge of God, even though He has declared His existence through the things that are made. So a student of science is without excuse for not coming to some kind of knowledge/understanding of creation. This is why, during the debate between ken Ham and Bill Nye, that Ken Ham said that this is really a clash of world views: those who see a Creator revealed through His creation, and those who refuse to see a Creator revealed through His creation. Believe me, scientists can be just as "political" as any lawyer, dancing around truth and twisting it as far as they can get away with.
