An adaptation in one lineage (e. g. predators) may change the selection pressure on another lineage (e. g. prey), giving rise to a counter-adaptation. If this occurs reciprocally, an unstable runaway escalation or ‘arms race’ may result. We discuss various factors which might give one side an advantage in an arms race. For example, a lineage under strong selection may out-evolve a weakly selected one (‘the life-dinner principle’). We then classify arms races in two independent ways. They may be… 

Host-Parasite Arms Races and Rapid Changes in Bird Egg Appearance

Coevolutionary arms races are a powerful force driving evolution, adaptation, and diversification. They can generate phenotypic polymorphisms that render it harder for a coevolving parasite or

Genetic structure of prey populations underlies the geographic mosaic of arms race coevolution

It is found that landscape-wide variation in the newt toxin is best predicted by neutral population divergence rather than the resistance of local predators, implying that neutral processes including gene flow—rather than reciprocal adaptation—comprise the greatest source of variation across the coevolutionary mosaic.

The geographic mosaic of arms race coevolution is closely matched to prey population structure

It is found that predator resistance and prey toxin levels are functionally matched in co‐occurring populations, suggesting that mosaic variation in the armaments of both species results from the local pressures of reciprocal selection, and supports the role of "trait remixing" in the geographic mosaic theory.

Family quarrels in seeds and rapid adaptive evolution in Arabidopsis

The results suggest that kin selection and conflict are important in plants, that the conflict includes not just the mother and offspring but also the triploid endosperm, and that, despite the conflict-reducing role of kinship, family members can engage in slow but steady tortoise-like arms races.

Host Specificity in Subarctic Aphids

Testing different levels of specificity in the most predominant species–species interactions on the planet will allow us to elucidate these patterns accurately and gives insight into where to direct future research.


The ability to reject mimetic eggs has most likely evolved as an adaptation against interspecific brood parasitism and may be the reason why the Yellowhammer is parasitized only occasionally.

The escalatory Red Queen

This study used a 25-year temporal sampling to decipher the demographic history of a plant pathogen: the poplar rust fungus, Melampsora larici-populina, and illustrates how antagonistic co-evolution can lead to population extinction and replacement.

It is demonstrated that two species with substantially different size may undergo parallel coevolution towards a smaller size under the same ecological conditions where a single species would exhibit an evolutionary arms race.

Habitat-dependent call divergence in the common cuckoo: is it a potential signal for assortative mating?

It is suggested that cuckoo calls differ sufficiently to allow recognition of habitat-specific individuals in the context of host-specific populations.

The Red Queen and King in finite populations

The effects of the various determinants of evolutionary rate: generation time, mutation rate, population size, and the intensity of natural selection are analyzed to provide insight into the demographic evolution of symbionts.



Selection, Spatial Distribution, and the Coexistence of Competing Fly Species

A genetic check on the blowfly population when it started its comeback showed that it had evolved into a more effective competitor than the housefly, and a multi-cell cage with increased space-time structure is now under investigation to see if these two species can evolve, coexist and occupy the same niche.

The Coevolution and Stability of Competing Species

For the cases considered, the co-evolved divergence of the consumers leads to greater global stability of the consumer community even though it has negligible effect on the local Lyapunov stability.

Resource partitioning among competing species--a coevolutionary approach.

Haploidploidy and the evolution of the social insect.

Evidence is presented from 20 species that the ratio of investment in monogynous ants is, indeed, about 1 : 3, and this discovery is subject to a series of tests, which provide quantitative evidence in support of kinship theory, sex ratio theory, and the assumption that the offspring is capable of acting counter to its parents' best interests.

How rare is phyletic gradualism and what is its evolutionary significance? Evidence from Jurassic bivalves

The favoured interpretation of phyletic size increase is a gradual delay in maturation time consequent upon a change in the organisms' adaptive strategy from the r-selected to the K-selected mode and is backed up by evidence on changing population numbers and distribution.

Defense of a Predator's Young by a Herbivorous Fish: An Unusual Strategy

One species of cichlid fish Cichlasoma nicaroguense was observed defending the young of the largest cichLid in the lake, the predator C. dovii, with added help from nonrelated individuals.

Were workers of eusocial hymenoptera initially altruistic or oppressed?

Studies of a primitively eusocial halictid bee, Lasioglossum zephyrum, strongly suggest that a major factor in originating a worker caste is selection at the individual level for queens that control
