In the image above, all the eggs in the top row are laid by ...Coevolution (reciprocal evolutionary change in interacting species) is posited as a major mechanism that creates new species. A challenge has been to understand how coevolution has shaped the patterns of relatedness of interacting species and the traits involved in the interaction. Ongoing advances in the field of molecular phylogenetics …

Arms race analogies have also been applied to explain coevolution in interactions that are closely related to predator-prey relationships, such as parasite-host and plant-herbivore interactions. Evidence from the fossil record The popularity of 'arms race reasoning' in thinking about predator-prey evolution does not appear to be based on …Common parasites and their hosts are thought to be engaged in co-evolutionary arms races, wherein adaptations by parasites to better infect host species and extract host resources are countered by ...In evolutionary biology, an evolutionary arms race is an ongoing struggle between competing sets of co-evolving genes, phenotypic and behavioral traits that develop escalating adaptations and counter-adaptations against each other, resembling an arms race. These are often described as examples of positive feedback. The co-evolving gene sets may be in different species, as in an evolutionary ...

While numerous examples have been observed of the evolution of traits via the predator prey relationship, some of the most interesting examples occur when the relationship is suspended. Evolutionary arms races. Predators and prey may often show an evolutionary pattern called escalation. ...

Example where a microbe is ...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. Under other ecological conditions (such as in ...

To keep up with the evolutionary arms race between drugs and bacteria, antibiotic discovery should occur at least as quickly as resistance mechanisms emerge, and policy should reflect this urgency. In 2012, Congress passed GAIN, the Generating Antibiotic Incentives Now Act.One example of an evolutionary arms race is in sexual conflict between the sexes, often described with the term Fisherian runaway. Thierry Lodé emphasized the role of such antagonistic interactions in evolution leading to character displacements and antagonistic coevolution.

We suggest that the ability of phages to support extensive engineering may have evolutionary origins in the billions-year-old ‘arms race’ between bacteria and phages, which selects for sequences and structures that are robust in the face of rapid evolutionary change. jacob stutzmanlawrence museumrs3 curses A military artificial intelligence arms race is an arms race between two or more states to develop and deploy lethal autonomous weapons systems (LAWS). Since the mid-2010s, many analysts have noted the emergence of such an arms race between global superpowers for better military AI, [8] [9] driven by increasing geopolitical and military tensions.
