By demonstrating the evolution of significant premating isolation, previous laboratory experiments have provided some evidence for the founder‐flush model of speciation. However, these experiments are subject to a number of criticisms, including the use of hybrid populations recently collected from the wild and the use of multiple bottlenecks. Here we present the results of a test of founder‐flush speciation using a single, well‐adapted laboratory stock of Drosophila melanogaster subjected to one founder‐flush event. The experiment was replicated at larger scale than previous studies, and results indicate that none of 50 independent founder‐flush lines evolved significant assortative mating relative to the control (base) population. This suggests a diminished emphasis on population bottlenecks in speciation of D. melanogaster and perhaps in general.
