Abstract: Antagonistic coevolution between hosts and parasites is believed to play a pivotal role in host and parasite population dynamics, the evolutionary maintenance of sex and the evolution of parasite virulence. Furthermore, antagonistic coevolution is believed to be responsible for rapid differentiation of both hosts and parasites between geographically structured populations. Yet empirical evidence for host-parasite antagonistic coevolution, and its impact on between-population genetic divergence, is limited. Here we demonstrate a long-term arms race between the infectivity of a viral parasite (bacteriophage; phage) and the resistance of its bacterial host. Coevolution was largely driven by directional selection, with hosts becoming resistant to a wider range of parasite genotypes and parasites infective to a wider range of host genotypes. Coevolution followed divergent trajectories between replicate communities despite establishment with isogenic bacteria and phage, and resulted in bacteria adapted to their own, compared with other, phage populations.

Bacteria–phage coevolution as a driver of ecological and evolutionary processes in microbial communities
TL;DR: This review sums up the current understanding of bacteria–phage coevolution both in the laboratory and in nature, and discusses recent findings on both thecoevolutionary process itself and the impact of coev evolution on bacterial phenotype, diversity and interactions with other species (particularly their eukaryotic hosts).

The arms race between bacteria and their phage foes.
TL;DR: The spectrum of anti-phage systems is reviewed and their evasion by bacteriophages is highlighted to enable the development of phage-based therapies and biotechnological tools and provide insights into the ecology and evolution of these microorganisms.

TL;DR: The results demonstrate, at both the genomic and phenotypic level, that antagonistic coevolution is a cause of rapid and divergent evolution, and is likely to be a major driver of evolutionary change within species.
Bacteria-phage antagonistic coevolution in soil.
TL;DR: It is suggested that rapid coevolution between bacteria and phage is likely to play a key role in structuring natural microbial communities and can be explained by fitness costs constraining the evolution of high levels of resistance in soil.

TL;DR: Recent studies that use laboratory-based microbial model systems to address ecological questions have significantly advanced the authors' understanding of processes that have proven difficult to study in field systems, including the genetic and biochemical underpinnings of traits involved in ecological interactions, and the ecological differences driving evolutionary change.

The Coevolutionary Process

- 15 Nov 1994
TL;DR: The geographic mosaic theory of coevolution was proposed by Thompson as discussed by the authors to understand the development of reciprocal adaptations and specializations in interdependent species, using examples of species interaction from a range of taxa.

Adaptive radiation in a heterogeneous environment

TL;DR: It is demonstrated that the elementary processes of mutation and selection alone are suifficient to promote rapid proliferation of new designs and support the theory that trade-offs in competitive ability drive adaptive radiation.

Sexual reproduction as an adaptation to resist parasites (a review)
TL;DR: P parasite coevolution is superior to previous models of the evolution of sex by supporting the stability of sex under the following challenging conditions: very low fecundity, realistic patterns of genotype fitness and changing environment, and frequent mutation to parthenogenesis, even while sex pays the full 2-fold cost.
