Primes¶
- Coevolution
- The structural insight is robust across substrates: a predator and its prey, a firm and its rivals, an exploit and its patch, a pathogen and an immune system, and a language and the minds that learn it all exhibit the same loop in which each move reshapes the conditions of the next, a generality Dawkins and Krebs (1979) developed in their arms-races treatment showing that asymmetries in the stakes of the contest (the "life-dinner principle") shape which side leads the escalation.
This sourceDevelops reciprocal-counteradaptation arms races and the "life-dinner principle," showing that asymmetric stakes (a lineage under strong selection out-evolving a weakly selected one) shape which side leads the escalation and that a best response must anticipate the provoked counter-response.
Supported in partVerified against the publisher's abstract
The abstract states the arms-race loop and life-dinner principle for asymmetric stakes, but not the cross-substrate list (firms, exploits, language) the claim asserts.
“For example, a lineage under strong selection may out-evolve a weakly selected one (‘the life-dinner principle’).”

- Competition
- It licenses reasoning about Selection (the relatively fit are differentially retained), about escalation and arms-race dynamics (rivals invest ever more to maintain relative position, often dissipating the very surplus they compete for), about niche differentiation as an escape from head-to-head rivalry (move to where the payoffs are no longer coupled), and about when adding competitors helps versus harms a system.
This sourceDevelops reciprocal-counteradaptation arms races and the "life-dinner principle," showing that asymmetric stakes shape which side leads the escalation and how a best response must anticipate the provoked counter-response — the canonical treatment of escalation as ever-increasing investment to hold relative position.
Supported in partVerified against the publisher's abstract
The abstract supports reciprocal counter-adaptation producing runaway escalation or an ‘arms race’, but not the claim’s dissipating-surplus or competitor-addition clauses, and only weakly its niche-differentiation strand.
“If this occurs reciprocally, an unstable runaway escalation or ‘arms race’ may result.”

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 2 of 2 citations: 2 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
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.
