The Red Queen hypothesis, proposed by [[entity-leigh-van-valen|Leigh Van Valen]] in 1973, is named for
the Red Queen in Lewis Carroll's *Through the Looking-Glass*, who tells Alice
that in her country "it takes all the running you can do, to keep in the same
place." Van Valen used the image to explain his "Law of Extinction": the
observation that a taxon's probability of extinction appears roughly constant
over time, independent of how long the taxon has already survived. The
underlying idea is that species exist in a continual coevolutionary
struggle — as one lineage adapts, the competitors, predators, and parasites
it faces adapt in turn, so that relative fitness is eroded as fast as it is
gained. Continuous adaptation is therefore required merely to maintain a
constant probability of survival, not to improve it.

The hypothesis is one of two distinct evolutionary ideas the vault tracks as
donors of metaphors to other fields; the other is [[entity-punctuated-equilibrium|punctuated equilibrium]]
([[claim-punctuated-equilibrium-derives-from-mayr-peripatric-speciation]]).
The two make different claims — Red Queen is about constant coevolutionary
pressure, punctuated equilibrium about long stasis broken by rapid change —
and should not be conflated.

The definitional content here clears the sourcing floor at Tier 4 (Wikipedia
is acceptable for settled definitions), but the specific "constant extinction
probability" formulation is Van Valen's own theoretical claim and traces to
his 1973 paper "A New Evolutionary Law," which the capture did not open. The
model was later carried out of biology and into organizational strategy by
William Barnett —
[[claim-barnett-applied-red-queen-to-organizational-competition]] — and the
capture used it as a lens on semiconductor capital arms-races
([[claim-rocks-law-is-moores-laws-economic-inverse]]).
