Primes

• Selection Vs Transmission Decomposition
  • The Price equation is the canonical formal statement of this decomposition.

    This sourceStates the Price equation: the change in a population's mean trait splits exactly into a covariance-of-trait-with-fitness (selection) term and a fitness-weighted within-unit (transmission) term.

• Variance Bounds Selection Response
  • The Price equation, in its most general form, is the formal apparatus that makes the cross-domain identity rigorous — but the intuition (variance bounds response) is portable without the formalism, and the formal version is available when precision is needed.

Mechanisms

• Covariance Selection-Term Calculation
  • The identity that licenses reading this covariance as "selection" is the Robertson–Price form, in which the covariance of value with relative fitness is exactly the selection differential.

    This sourceExpresses selection as the covariance between character value and relative fitness, equivalent to the selection differential.

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? Not recorded. Neither this nor any other of the 3 citations of this work carries a recorded support check.

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.
