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.
