Background: Forty years ago, G.C. Williams predicted that reproductive effort should be inversely related to the average adult life span across species.

Aim: Use allometric life-history theory to refine that prediction.

Result: Reproductive effort should be inversely proportional to average adult life span, a −1 scaling rule.

Keywords: allometry, life history, optimization, trade-offs, Williams’ hypothesis.
