Physiological mechanisms: humans and other animals use to defend their bodies from invasion by other organisms (but without harming yourself) Observing survivors of epidemic disease that were untouched (immune) when face to the same infection at a later time. Advantage of reproducing and evolving much more rapidly than their human hosts. Ie; ebola can reproduce every 20 minutes.
