TL;DR: A perspective on the context and evolutionary significance of hybridization during speciation is offered, highlighting issues of current interest and debate and suggesting that the Dobzhansky–Muller model of hybrid incompatibilities requires a broader interpretation.

TL;DR: This study provides a roadmap to the emerging field of speciation genomics by showing that the genomic landscape of species differentiation is highly heterogeneous with approximately 50 ‘divergence islands’ showing up to 50-fold higher sequence divergence than the genomic background.

TL;DR: Characterization of genomic differentiation in a classic example of hybridization between all-black carrion crows and gray-coated hooded crows identified genome-wide introgression extending far beyond the morphological hybrid zone, indicating localized genomic selection can cause marked heterogeneity in introgressive landscapes while maintaining phenotypic divergence.

TL;DR: Before the real-world conservation potential of genomic research can be realized, current infrastructures need to be modified, methods must mature, analytical pipelines need to been developed, and successful case studies must be disseminated to practitioners.

TL;DR: This Review explores methodological trends in speciation genomic studies, highlights the difficulty in separating processes related to speciation from those emerging from genome-wide properties that are not related to reproductive isolation, and provides a set of suggestions for future work in this area.
