The possibility that iteroparity may be an evolutionary response to uncertain survival from zygote to first maturity is examined in a competition model and a genetic model. The competition model used is an alternative to the logistic model and is based on the Ricker formulation of population growth. The genetic model is a straightforward two-allele system. Both models show clear advantage in iteroparity if there is uncertainty from zygote to first maturity. Illustrative material on marine plankton-feeding fishes suggests the modeling is realistic. Consideration of other evidence suggests the approach may contribute to understanding the dynamics of evolution.
