First proposed in 1973 by Leigh Van Valen, this part of the ...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.Abstract Evolutionary conflict and arms races are important drivers of evolution in nature.

The interaction between bats and their insect prey, in particular moths, is one of the most cited examples of such an evolutionary arms race. It comes with a twist – the weaponry used by each is largely based on sound and hearing. Evolving attacks and defensive systems, Under some ecological conditions (such as in some predator-prey interactions or between competitors for a resource), an antagonistic interaction between two species can coevolve to enhance the antagonism; the species “build up” methods of defense and attack, much like an evolutionary arms race.
