The developmental history of organisms is critical in determining phenotypic outcomes. Shifts in environmental factors can constrain or redirect ontogeny in ways that traditional models of plasticity have failed to predict. In this study we examined the impact of shifting between high and low thermal regimes during the embryonic stage in Drosophila melanogaster . We found that extreme temperatures (both high and low) resulted in larger flies at enclosure than the temperature during subsequent development would have predicted. Thus, embryonic temperature poses a critical factor that can have lasting effects on morphology and fitness.
