Parasites are ubiquitous in biological systems and antagonistic coevolution between hosts and parasites is thought be a major ecological and evolutionary force. Recent experiments using laboratory populations of bacteria and their parasitic viruses, phage, have provided the first direct empirical evidence of antagonistic coevolution in action. In this article we describe this model system and synthesise recent findings that address the causes and consequences of antagonistic coevolution.

Drosophila seminal fluid proteins (SFPs) are often cited as an example of interlocus sexual conflict, wherein the proteins increase male fitness while decreasing female fitness, spurring recurring female counter adaptations and rapid molecular evolution. This model predicts that male-expressed genetic variation in the accessory gland, which produces seminal fluid, should generate counter-evolving genetic pathways in females, resulting in sexual coevolution. Using a trio of D.

Local adaptation is a central evolutionary process for creating/maintaining variation of traits mediating antagonistic interactions. However, few studies have evaluated the local adaptation of plants to their biological counterparts such as herbivores across the plants' distribution. Most studies evaluating local adaptation to herbivores have focused on specialist systems, where local adaptation is likely to occur.

The Red Queen model of antagonistic coevolution has been the preferred explanation for certain biological phenomena, such as extreme genetic diversity and -species polymorphisms in disease genes. This model has been studied on diverse timescales using direct observations (covering days to a few years), archived material (several decades), postglacial processes (about 10,000 years), and phylogeographic and phylogenetic methods (millions of years). Here, I review the evidence for specific antagonistic coevolution in the host-parasite - model system, paying particular attention to the timescales addressed by different approaches.

This model predicts that male-expressed genetic variation in the accessory gland, which produces seminal fluid, should generate counter-evolving genetic pathways in females, resulting in sexual coevolution. Using a trio of populations exhibiting substantial SFP expression divergence due to recent selection, we test for coevolution in the female post-mating transcriptome in the lower reproductive tract and head.

The tendency for the genital morphology of animals to diverge more rapidly than other traits is one of the most pervasive evolutionary patterns in animal form. Current controversy regarding explanations of this pattern stems in part from the difficulty of observing the behavior of male genitalia during copulation. This limitation is reduced in tipuloid crane flies, because most of the male's elaborate, divergent genital structures remain outside the female during copulation.
