We measured age-specific fecundity and survival in recombinant inbred lines ofDrosophila melanogasterthat were derived from an artificial selection experiment for delayed reproduction. Age at peak oviposition is highly heritable (h2B= 0.55). We find three qualitative categories of peak oviposition: early-, midlife-, and bimodal. Genetic correlations between life span and early fecundity are not significantly different from zero, but correlations with midlife fecundity are positive and statistically significant. Long-lived genotypes exhibit a midlife fecundity peak. There is no evidence for a shift of reproductive effort from early to later stages. The existence of qualitatively recombinant phenotypes, including “superflies” that exhibit both enhanced survival and high levels of early fecundity, argues against the widespread idea that life history evolution inDrosophilais dominated by negative pleiotropy. There is clear evidence of age-specific adaptation in the timing of oviposition.
