It's a common misconception that evolution is a matter of faith, because it happens too slowly to observe. Here's the way one reader sees it: "I don't see any fish walking around, nor do I see any other creature in mid-evolving mode. . . . Simply stated, both creationism and evolution should be taught as competing theories; both are not provable, and both cannot be duplicated in a lab."
But evolution does happen in the lab, in real time, and it's bad news for us because such rapid evolution allows organisms that can kill us by evading drugs, vaccines, and our own immune systems.
