Coevolution refers to the phenomenon of reciprocal evolutionary change between groups of animals. Essentially, it’s a tit-for-tat situation. Take, for example, a group of impalas in the savannah. They are agile and can elude their main predators, cheetahs.

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.

Predator-Prey Arms Races. The constant competition between pred­ators and prey animals is a major stimulus to evolution, sometimes called an evolutionary arms race. Predators adapt to prey populations, and prey populations adapt to innovations of a predator. Bats have a very effective system for locating insects, using high-frequency sonar ... Evolutionary arms races are common to a range of genetic conflicts, including host–pathogen interactions (see the figure, part a). For example, if a host immunity factor recognizes some feature ...often incur a reduction in fitness and are thought to engage in an evolutionary arms race with the rest of the genome as the genome evolves mechanisms to suppress the drive [2,4–8]. However, it is important to note that while the pro-cess of drive is a selfish one, loci that experience drive can also be neutral, orThis arms race triggers rapid evolution towards a new genomic balance.

By 2014, some 90 percent of planted U.S. corn, soybean and cotton crops were genetically modified to withstand glyphosate. Unfortunately, as the evolutionary arms race progresses, many weeds have figured out how to evolve resistance to glyphosate, making the chemical increasingly ineffective and forcing farmers to look for other or new …A moment arm is the distance between the joint axis and the line of force acting on the joint; an example is using a wrench to loosen a nut, the wrench acts as a moment arm and produces more force than trying to free the nut by hand.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 ...

We begin by attempting to answer these two questions for one example of an arms race, namely birds as predators of cryptic prey. Alexandra Pietrewicz and ...

Nature 516 , 242–245 (2014) Article CAS Google ScholarThis sexual antagonism between the sexes within the majority of mating patterns therefore generates an evolutionary ‘arms race’ in which males evolve adaptations that benefit their own reproductive interests, ... A good example might be selection on males to evolve genitalia that deposit spermatozoa closer and closer to the …A competing evolutionary idea is the court jester hypothesis, which indicates that an arms race is not the driving force of evolution on a large scale, but rather it is abiotic factors. [27] [28] The Black Queen hypothesis is a theory of reductive evolution that suggests natural selection can drive organisms to reduce their genome size. [29]

Jul 1, 1999 · Natural enemies seem to behave in much the same way; improved abilities in one species demand compensatory improvements by its enemies if they are to continue to be successful. However, the use of the arms race analogy to describe an evolutionary phenomenon invokes specific criteria. In an evolutionary race, the players are lineages, not ...

Arms Race. Sexual conflict occurs when the two members of a pair have conflicting optimal fitness strategies concerning reproduction, leading to an evolutionary arms race between males and females (Arnqvist and Rowe, 2005).

Pathogens are subjected to several evolutionary selective pressures that are intrinsically dependent on their mode of transmission and dispersal ability (Ewald, Reference Ewald 1995; Frank, Reference Frank 1996; Powell, Reference Powell 2019).For example, pathogens transmitted by mobile vectors might evolve towards phenotypes of higher …The P. syringae effector protein AvrPtoB provides a good example of the evolutionary arms race occurring between pathogen and host (Fig. 1). As mentioned previously, AvrPtoB contains an N-terminal domain between residues 1 and 307 that is involved in inhibiting several components of PTI, including FLS2, BAK1 and CERK1, which are involved in the ...Butch’s original quest to figure out what killed the hunters in their campsite started him on a serious journey into evolutionary biology. After discovering that the newts were indeed toxic, he began investigations into why they had evolved such extreme toxicity, and, in the process, uncovered a raging battle — an evolutionary arms race. 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 ...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.Predator–prey relationships provide clear examples of arms races, with predators having a range of general adaptations to capture prey, which have evolved varied defences. But there is little evidence for genuine coevolutionary responses in the sensory systems of the predators to better overcome prey defences.A competing evolutionary idea is the court jester hypothesis, which indicates that an arms race is not the driving force of evolution on a large scale, but rather it is abiotic factors. [27] [28] The Black Queen hypothesis is a theory of reductive evolution that suggests natural selection can drive organisms to reduce their genome size.
