Without going into all the complex biochemistry of diversity, the important thing for us to remember is that microbes were here before us, have coevolved with us while we humans occupy the earth, and will be here after we are gone. In our superior human mind-set, we think of our species as being largely in control. But to understand the true biologic sense of the power of microbes, we must never forget that we are the ones trying to anticipate and respond to their evolution, not the other way around.
