Species such as the Protomognathus americanus, a notorious slavemaker in North America that relies on its subjects to survive, have driven neighbouring populations to devise counter measures that ensure their own survival. No longer could the common worker ant idly sit by and allow the slavemaker to reduce it to a species of day care providers -- what is referred to as "brood parasitism", where slaves are forced to tend to their captors' young.
"Parasite pressure has led to the development of defensive strategies in hosts," says the study, "which, in turn, resulted in the evolution of counter-adaptations in parasites, a process which may lock both species in a coevolutionary dynamic, potentially escalating in an evolutionary arms race."

I have only one thing to do and that's
Be the wave that I am and then
