AbstractThe allopatric model of speciation has dominated our understanding of speciation biology and biogeography since the Modern Synthesis. It is uncontroversial because the cessation of gene flow during allopatry will allow reproductive isolation to readily emerge as a by-product of evolutionary divergence. However, whether allopatric speciation is common has rarely been systematically tested across a continuum of closely-related species.
