Apr 15, 2019 · Author summary Exaggerated traits involved in species interactions, such as extreme running speeds in predator and prey, have long captivated the imagination of evolutionary biologists and inspired the durable metaphor of the coevolutionary arms race. Despite decades of research, however, we have only a handful of examples where coevolution has been rigorously established as the cause of trait ... An arms race occurs when two or more countries increase the size and quality of military resources to gain military and political superiority over one another. The Cold War between the United ...An evolutionary arms race is an evolutionary competition between predator/prey species. As sets of co-evolving genes develop adaptations and counter-adaptations against each other, predators and prey may often show an evolutionary pattern called escalation: as predators evolve more powerful weapons prey develop more powerful defenses against ... More evidence of an evolutionary ‘arms race’ between genes and selfish genetic elements November 11, 2021 University of Rochester biologists Daven Presgraves and Christina Muirhead studied the genomes of three closely related species of Drosophila (fruit flies) and found further evidence of an evolutionary arms race at play.Originally described by the late evolutionary biologist Leigh Van Valen, the Red Queen hypothesis posits that the evolutionary arms race between hosts and their pathogens selects for discrete, genetically encoded events that lead to competitive advantages over the other species. Examples of immune e …Oct 1, 1986 · Biologists have often used simple analogies to help them think about complex processes in evolution. The mutual evolution of predator and prey has often been conceived of as an arms race. An increase in the armaments of one contestant in the race simply causes the other contestant to increase armaments in response. Understanding the sequence of evolutionary events will be useful to understand that putative arms race. For example, the colours and scents of flowers probably evolved long after the pollinator sensory systems that perceive them, and not vice versa 102, 103, but how does this apply to other traits, such as reward quality versus …21.11.2019 г. ... For example, we know that Darwin was aware of it. 1:38. Perhaps, the best known arms race, and the contemporary event for which the phrase is ...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 …The result of such sexual conflict is, in theory, an "arms race" between the sexes whereby male persistence is matched by female resistance. Such arms races are, however, very difficult to study ...The cheetah’s explosive sprint and gazelle’s nimble leap were shaped by a coevolutionary arms race over millennia. Unlike the evolutionary footrace between cheetahs and gazelles, yucca moths and Joshua trees have a special type of coevolutionary relationship known as an obligate mutualism. Each partner depends on the other for survival.The idea that, in order for a species to maintain a particular niche in an ecosystem and its fitness relative to other species, that species must be constantly undergoing adaptive evolution because the organisms with which it is coevolving are themselves undergoing adaptive evolution. When species evolve in accordance with the Red Queen ...Jan 7, 2010 · 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 have opened exciting avenues to examine both ancient and ... Consideration of complex geographic patterns of reciprocal adaptation has provided insight into new features of the coevolutionary process. In this paper, we provide ecological, historical, and geographical evidence for coevolution under complex temporal and spatial scenarios that include intermittent selection, species turnover across localities, and a range of trait match/mismatch across ...In one estimate, for example, ... Both cheetah and gazelle are in an arms race: where evolutionary change of the predator drives either compensatory change in the prey—or extinction. Any increase in gazelle speed or maneuverability exerts evolutionary pressure on the cheetah to notch up its own speed.Toxic Newts: Evolutionary history is filled with "arms race" relationships between organisms locked in struggles of adaptation and escalation. This is an example of coevolution.A molecular arms race is progressively being unveiled between prokaryotes and viruses. Prokaryotes utilize CRISPR-mediated adaptive immune systems to kill the invading phages and mobile genetic elements, and in turn, the viruses evolve diverse anti-CRISPR proteins to fight back. The structures of several anti-CRISPR proteins have now …Toxic Newts: Evolutionary history is filled with "arms race" relationships between organisms locked in struggles of adaptation and escalation. This is an example of coevolution.While Skype seemed to have a horse in both races — professional workplace chat services and social video chatting — other services emerged, carving out specific niches. For example, FaceTime became the go-to social video chat service.We review some examples, including for controlled phage therapy. 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.
Jun 26, 2015 · One particular example of this is the arms race between bats and moths. The interaction between bats and their insect prey, in particular moths, is one of the most cited examples of... In a classic example of the evolutionary arms race between a host and a pathogen, the myxoma virus -- introduced to control the rabbit population in Australia in 1950 -- has developed a novel and ...... evolutionary arms race ... Such changes in the ways moths and bats try to get the better of each other is an example ...Coevolution is undisputed as one of the most important processes shaping biodiversity. The importance of coevolution goes far beyond the classic examples, such as predator–prey …“Other examples of tense relationships that drive evolution, counterevolutionary responses and one-upmanship include parasites and their hosts, seeds and seed-eating bugs, hunters and prey.” According to Chaboo, such arms races influence the mechanics of evolution, as traits developed for defense over time result in entirely new species.

The arms race concept may help to reduce the mystery of why cuckoo hosts are so good at detecting cuckoo eggs, but so bad at detecting cuckoo nestlings. The evolutionary contest between queen and worker ants over relative parental investment is a good example of an intraspecific asymmetric arms race. Ex. Consider one of his first examples – a narrative on the relationship between bears and seals. Many years ago, brown bears may have found it ...
Alternatively, the arms race may be between members of the same species, as in the manipulation/sales resistance model of communication (Dawkins & Krebs, 1979) or as in runaway evolution or Red Queen effects.
