Evolutionary arms races are well known. Predator and prey (or pathogen and host) adapt to each other’s respective defenses and offenses, sharpening their skills to survive. That pertinent adaptations transpire is beyond doubt. How the information required is acquired for evolutionary adaptations is an enigma.
From viruses on up, many parasitic organisms manipulate host behaviors to their whims, so that they may better propagate. While hundreds of such instances have been seen in a wide variety of species, how parasites manage to acquire the fine-tuned acuity to effect host manipulation is inexplicable.
