Until complete reproductive isolation is achieved, the extent of differentiation between two
diverging lineages is the result of a dynamic equilibrium between genetic isolation and …

The two “rules of speciation”—the Large X-effect and Haldane's rule—hold throughout the
animal kingdom, but the underlying genetic mechanisms that cause them are still unclear …

Statistical analysis of aligned DNA sequences, both among and within species, has proven
to be a valuable tool for inferring the evolutionary history of genetic loci. Of particular interest …

Low levels of allozyme heterozygosity in populations are often attributed to previous
population bottlenecks; however, few experiments have examined the relationship between …

With the advent of next‐generation sequencing technologies, large data sets of several
thousand loci from multiple conspecific individuals are available. Such data sets should …
