Predator–prey relationships provide clear examples of arms races, with predators having a range of general adaptations to capture prey, which have evolved varied defences. But there is little evidence for genuine coevolutionary responses in the sensory systems of the predators to better overcome prey defences.The CFRs revealed the outcome of this arms race was strongly dependent on whether there was a shared evolutionary history in the parasite–final host system, with contrasting outcomes for experienced and naive hosts. For naive hosts, the CFR curves revealed similar consumption rates of infected and non-infected prey.Biologists have often used simple analogies to help them think about complex processes in evolution. The mutual evolution of predator and prey has often been conceived of as an arms race.
