This world belongs to microbes (Johnson)

By any rational measure, this world belongs to microbes. They were mastering the subtleties of evolution three billion years before the first multicellular organism appeared. They continue to evolve and adapt in a tiny fraction of the time it takes us to reproduce once. They flourish in polar ice caps, in boiling water, and amid radioactive waste. We exist only because some of them find us useful. Ninety percent of the cells in our bodies are bacteria. The entirety of human evolution has taken place in an environment saturated with microbes, and humans are so firmly adapted to the routine of sheltering allies and rebuffing enemies that the removal of either can devastate our defense systems.
