Red Queen hypothesis - Wikipedia

Red Queen Hypothesis: Proposed by Leigh Van Valen in 1973, the hypothesis argues that competing organisms must continually adapt to the changing ecosystem in order to survive (continue to participate in the ecosystem). This is the “running in place just to keep up” hypothesis.

The scientists in Plön have therefore tested the Red King’s Hypothesis in a multiplayer model. According to this, it was confirmed that the Red King’s Hypothesis is only valid in pairwise mutualistic relationships. As soon as several parties are involved, it becomes considerably more complicated. “Then more rapid evolution can be favoured for a party as well,” explains Chaitanya Gokhale from the Max Planck Institute for Evolutionary Biology.

The continual battle between Google and link spammers, for example, is well-depicted by the Red Queen Scenario; there are no clear winners in this relationship and I doubt there will be until the Searchable Web Ecosystem loses its ability to generate sufficient revenue to inspire one side or the other (or both).

You can certainly find examples in the natural Terro-ecosystem to support all three hypotheses: the interaction between humans and flu viruses is a pretty good illustration of the Red Queen Principle; the diversification of species across differentiated landscapes as evidenced by divergent evolution in the Galapagos Islands is a good illustration of the Court Jester Hypothesis; and the Coelacanth, a prehistoric fish that has survived to this day — outliving many of its contemporaries and their descendants without changing — illustrates the Red King Principle.

The Red Queen hypothesis is well-accepted in evolutionary biology.

Michael You’re committing one of the classic SEO community blunders by looking for fault in the algorithm. What is the point of posing a hypothetical question if the question is predicated upon a flawed argument, which is that the algorithm is imperfect and therefore Google is morally wrong to prevent us from accepting helpful links we did not seek?

The Red Queen Hypothesis has been described as an arms race of coevolution, and much like Alice on the chessboard, the direction a species will take is unpredictable, sometimes zigging when it seems like it should have zagged. In the game of evolution, much like Carroll’s looking-glass world, tracing the life history of species is anything but linear.

Red Queen Hypthesis – 358381 – Социальная сеть Overa

Van Valen developed the Red Queen Hypothesis to support his theory that the probability of was independent of time. In other words, the likelihood that an organism would undergo or defy extinction had little to do with how long that organism had been in existence. He also used the hypothesis to explain the advantage of sexual reproduction over asexual reproduction. Because sexual reproduction involves —the combining of maternal and paternal —genetic diversity is safeguarded. Genetic variability is imperative for survival, because it enables new generations to readily adapt to environmental and coevolutionary demands.

Through the Looking Glass: The Red Queen Hypothesis …

Van Valen named the idea "the Red Queen hypothesis,"because, under this view, species had to "run" (evolve)in order to stay in the same place (extant).

This race is known as the Red Queen hypothesis

Van Valen introduced his hypothesis in 1973 in a paper titled “A New Evolutionary Law.” His idea was then considered so obscure that the paper was rejected by multiple journals. To get it published, Van Valen started his own journal, Evolutionary Theory. Despite the initial widespread skepticism surrounding the Red Queen Hypothesis, the idea that coevolutionary interactions exert a strong influence on adaptation and natural selection is today generally accepted.

In ‘s Through the Looking Glass (1871), a sequel to his Alice’s Adventures in Wonderland (1865), Alice learns from the Red Queen that, in Carroll’s surreal land of the chessboard, bordered by hedges and brooks, running is all she can do—she must run simply to stay in place. The feeling of constant movement but little progress is something we can all relate to, but evolutionary biologist Leigh Van Valen took it a step further, developing the Red Queen Hypothesis, in which he claimed that organisms are constantly adapting and undergoing because they are competing with coevolving species, trying to maintain an advantage in a world constrained by finite energy and space.

The Red Queen is a metaphor for evolutionary change

What is required, however, is an integrated, systematic approach that will guide us towards those systems in which the Hamilton-Zuk hypothesis is most likely to be important and which will allow us to place this model in its proper place (with respect to relative importance) among the other mechanisms that have been suggested.
