A quiet scientific revolution has been taking place over the last few years as a consequence of strides in genomic science and molecular techniques. These advances have transformed the way humans view themselves as biological organisms. This revolution is the discovery of the human microbiome and with it, the realization that the human body is not simply composed of innate cells and the matrices they produce; i.e., collagen, bone minerals, etc. The body is also composed of a plethora of microbes, in numbers many times that of one’s “own” cells. This idea has been addressed by the popular press, and appears to be reaching the general public now.
