  • A long-standing model illustrating how new species can arise through ‘circular overlap’, without interruption of gene flow through intervening populations, has now been confirmed among passerine birds (Irwin et al, 2005). The new study of the Eurasian greenish warbler (Phylloscopus trochiloides) complex shows that reproductive isolation, the hallmark of biological species, can arise through ‘isolation-by-distance’ (Slatkin, 1993), such that large distances themselves restrict gene flow.
