Although not a new idea, recent studies suggest that differences in the composition of symbiotic microbes between hosts can lead to reproductive isolation, and as a consequence also to speciation. Despite the fact that microbes are universally present in eukaryotes, they are rarely considered as a driving force of speciation, and chances are their contribution to speciation is overlooked. Symbiotic bacteria of the genus Wolbachia are known to affect their hosts’ reproduction in adaptive manners to improve the propagation of the maternally transmitted endosymbiont throughout populations. These reproductive alterations that can result in postmating isolation via cytoplasmic incompatibilities, have recently been shown to foster also premating isolation in some host symbiont associations such as the Drosophila paulistorum species complex, giving even more reason to assume that Wolbachia can play a significant role in host speciation.
