"Disease gets a bad rap, doncha think? For being filthy, chaotic... eehh, but that actually describes people who get sick. Disease itself is very pure. Single-minded. Bacteria have one purpose: Divide and conquer. That's why, in the end, it always wins."
"Early on, evolution branched into two distinct paths: independent organisms—those that exist on their own in the natural world—and parasites—organisms that live on other organisms. And it was, by far, the parasites that proved the more successful of the two branches... These two strains of evolution have been locked in a primordial arms race, constantly evolving to best each other for supremacy of this planet. As parasites evolve to perfect their systems against a species of host, the host evolves to evade their attack. Scientists call this theory of an eternal genetic struggle the Red Queen Hypothesis—a name taken from Lewis Carroll's Through the Looking Glass."
