A New Evolutionary Law.

Van Valen, L. (1973). A New Evolutionary Law. Evolutionary Theory, 1(1), 1-30.

Retired. This entry was not a citation. Our extractor stored an inline prose definition from the article as though it were a bibliographic record, so its title is the name of a concept rather than of a published work. The page is kept because links to it still resolve, but it is withdrawn from the reference list. This entry is kept so the citations that pointed at it still resolve, and so the correction is visible rather than silent.

Primes

• Coevolution
  • The concept answers a recurring problem across domains: why do strategies that work brilliantly against a fixed opponent decay so reliably against a responsive one, and why does effort so often buy only the preservation of the status quo rather than genuine gain?

    This sourceIntroduces the Red Queen hypothesis: the observation of an approximately constant extinction probability within taxa, explained as a biotic environment that degrades each species' adaptive advantage as fast as it is won, so continual adaptation buys only the maintenance of relative position.

• Non-Stationary Objective
  • In evolutionary biology, Red Queen dynamics — coevolving species each forming a moving fitness target for the other — is the canonical biological case.

    This sourceIntroduces the Red Queen hypothesis: coevolving species each form a continuously moving fitness target for the other, the canonical biological non-stationary objective.

Domain-specific

• Red Queen Hypothesis
  • The characteristic result is a treadmill—substantial evolutionary activity without a durable improvement in position relative to the evolving biotic environment.

Mechanisms

• Adaptive Mix Review
  • This is the cyclic field's version of the Red Queen problem: you have to keep adapting merely to hold your position, but adapting to the last move leaves you a step behind the counter to it.

    This sourceProposes that continuing evolutionary change is required merely to maintain relative fitness in a coevolving environment.

• Red Queen Dynamics Review
  • The review classifies the regime as a Red Queen treadmill

    This sourceDefines Red Queen dynamics as continual adaptation needed merely to maintain relative fitness.

Verification

Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.

Does it back the claim? Not recorded. Neither this nor any other of the 5 citations of this work carries a recorded support check.

Was it audited? Yes. A second, independent pass read the citation against the article text and recorded a verdict.

Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
