Genetic surveys are uncovering the diversity of bacteria, and are causing the species concepts used to categorize these to be questioned. One difficulty in defining bacterial species arises from the high rates of recombination that results in the transfer of DNA between relatively distantly related bacteria. Barriers to this process, which could be used to define species naturally, are not apparent. Here, we have reviewed conceptual models of bacterial speciation and simulate speciation in silico. Our findings suggest that the rate of recombination and its relation to genetic divergence, have a strong influence on outcomes: we propose that a distinction be made between clonal divergence and sexual speciation. Hence, to make sense of bacterial diversity we need data not only from genetic surveys, but also from experimental determination of selection pressures and recombination rates, and from theoretical models.
