Red Queen hypothesis

This has elsewhere been described by the Red Queen Hypothesis.

The high dynamics associated with these interactions are summarized in the Red Queen hypothesis.

This paradox, of two or more species changing yet staying in the same co-evolutionary relationship, is what gave rise to the Red Queen hypothesis.

The Red Queen Hypothesis captures the idea that there is a constant 'arms race' between co-evolving species.

Parker reviewed numerous genetic studies on plant disease resistance and failed to uncover a single example consistent with the assumptions of the Red Queen hypothesis.

This result is consistent with the Red Queen hypothesis that sexual reproduction is favoured during host-parasite coevolution.

The second is that there is selection that undergoes a frequency-dependent cycle - and is called the Red Queen hypothesis.

"Where Have All the Species Gone - Nature of Extinction and the Red Queen Hypothesis."

The second hypothesis for the maintenance of MHC diversity by parasites is the Red Queen Hypothesis.

Barnosky acknowledges in the 2001 paper that the Court Jester hypothesis is not necessarily inconsistent with the Red Queen hypothesis:

The original idea of the Red Queen hypothesis (macroevolutionary) was given by Leigh Van Valen in order to explain the "Law of Extinction".

The term "Court Jester hypothesis" was coined by Anthony Barnosky in 1999 in reference to the Red Queen hypothesis.

The microevolutionary version of the Red Queen hypothesis was proposed by Bell (1982), also citing Lewis Carroll, but not citing Van Valen.

Further evidence for the Red Queen hypothesis were provided by observing long-term dynamics and parasite coevolution in a "mixed" (sexual and asexual) population of snails (Potamopyrgus antipodarum).

The Inbreeding Avoidance Hypothesis has less to do with host-parasite relationships than does the Heterozygote Advantage Hypothesis or the Red Queen Hypothesis.

If this is the case, either through the Heterozygote Advantage Hypothesis or the Red Queen Hypothesis, then selection will also favor mating practices that are MHC-dependent.

Ecologists have the Red Queen Hypothesis, which suggests that sometimes organisms have to evolve just in order to hang on in a changing environment - running as fast as they can to stay in place.

Generally, the extreme polymorphism of MHC genes is believed to be selected for by host-parasite arms races (the Red Queen hypothesis), however disassortative mate choice may maintain genetic diversity in some species.
