Evolutionary arms race example. This 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, and females then evolve counter-adaptations [7]. A good example might be selection on males to evolve genitalia that deposit ...

universal importance of arms races in all evolutionary change. Ours is the more modest aim to suggest that the arms race metaphor leads to new and productive habits of thought about old and familiar material. We shall organize our discussion around a two-way classification of arms races. An arms race may be interspecific or intraspecific.

Evolutionary arms race example. This arms race is known as co-evolution, the process by which the interactions between two species affect the evolutionary development of both. It's been going on since the Cambrian explosion more than half a billion years ago, and it will continue spawning new bursts of diversity long after we humans have eaten ourselves into extinction.

The Red Queen Hypothesis. The Red Queen hypothesis was first proposed by Leigh Van Valen in 1973, and is a coevolutionary hypothesis describing how reciprocal evolutionary effects among species can lead to some particularly interesting outcomes. While Van Valen specifically addressed macroevolutionary extinction probabilities, the hypothesis ...

For nearly 400 million years, the cephalopods remained some of the most dominant creatures in the sea, competing in an endless evolutionary arms race with jawed fish and large marine reptiles.This 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, and females then evolve counter-adaptations [7].

We must recognize that these pathogens (such as the flu virus shown at right) are continuously evolving entities in order to develop better ways to fight them and control their evolution.The arms race - Understanding Evolution Predator/prey coevolution can lead to an evolutionary arms race. Consider a system of plant-eating insects. Any plant that happens to evolve a chemical that is repellent or harmful to insects will be favored. The most dramatic examples of avian coevolution are probably those involving brood parasites, such as cuckoos and cowbirds, and their hosts. The parasites have often evolved eggs that closely mimic those of the host, and young with characteristics that encourage the hosts to feed them.
