Your little example about the skin of a baby has nothing to do with evolution. You need to learn the difference between micro and macro evolution. Macro evolution is the biggie that causes all the debate. What you described is not that.
The other stuff about the bacteria is just ridiculous to bring up in an evolution forum. I don't see the correlation at all. This bacteria obviously has some sort of immune system that has a built-in ability to dodge obsticles and a desire to survive...just like we humans do. Our bodies similarly adapt, change and overcome illnesses and diseases all the time. This is not evolution. You're seeing things that simply aren't there.
