Innate immune system: The innate immune system recognizes patterns so as to respond quickly to challenge. Coding for pattern recognition is hard wired into our DNA, thought to be through selective pressures through time (e.g., if unable to identify a threat such as a lethal virus, extinction could occur, leaving individuals with the ability to respond, the ability to survive).
