How genome divergence eventually leads to speciation is a topic of prime evolutionary *** islands of elevated divergence are frequently reported between diverging lineages,and their size is expected to increase with time and gene flow under the speciation-with-gene-flow ***,such islands can also result from divergent sorting of ancient polymorphisms,recent ecological selection regardless of gene flow,and/orrecurrent background selection and selective sweeps in lower combination *** is challenging to disentangle these nonexclusive alternatives,but here we attempt to do this in an analysis of what drove genomic divergence between four lineages comprising a species complex of desert poplar *** this complex we found that two morphologically delimited species,Populus euphratica and Populus pruinosa,were paraphyletic while the four lineages exhibited contrasting levels of gene flow and divergence times,providing a good system for testing hypotheses on the origin of divergence *** show that the size and number of genomic islands that distinguish lineages are not associated with either rate of recent gene flow or time of ***,they are most likely derived from divergent sorting of ancient polymorphisms and divergence *** found that highly diverged genes under lineage-specific selection and putatively involved in ecological and morphological divergence occur both within and outside these *** results highlight the need to incorporate demography,absolute divergence measurement,and gene flow rate to explain the formation of genomic islands and to identify potential genomic regions involved in speciation.
