Genomics and the origin of species
TLDR
Emergent trends and gaps in understanding are identified, new approaches to more fully integrate genomics into speciation research are proposed, and an integrative definition of the field of speciation genomics is provided.
The genomics of speciation-with-gene-flow.
Sympatric speciation in phytophagous insects: moving beyond controversy?
TLDR
The evidence for sympatric speciation via host shifting for phytophagous insects is reviewed and a set of testable predictions for distinguishing geographic mode (allopatric versus sympatrics) of divergence are proposed.
Host fidelity is an effective premating barrier between sympatric races of the apple maggot fly.
TLDR
The results verify that host-associated adaptation can produce reproductive isolation as a correlated character (a key premise of sympatric speciation) and represents one of the few or perhaps only example in animals where the intra-specific isolating effects of specific phenotypes have been quantified in nature.
Widespread genomic divergence during sympatric speciation
TLDR
Results highlight how the individual genes driving speciation can be embedded within an actively diverging genome, and illustrate how these continents can exhibit variable topography, depending on selection strength, availability of preexisting genetic variation, linkage relationships, and genomic features that reduce recombination.
Establishment of new mutations under divergence and genome hitchhiking
TLDR
It is found that the strength of selection acting directly on a new mutation is generally the most important predictor for establishment, with divergence and genomic hitchhiking having smaller effects.
Allopatric genetic origins for sympatric host-plant shifts and race formation in Rhagoletis
TLDR
Evidence is reported suggesting a surprising source of genetic variation contributing to sympatric host shifts forephritid fruit flies belonging to the Rhagoletis pomonella sibling species complex, which originated in a different time and place than the proximate ecological host shifts triggering sympatrics divergence.

TLDR
The results show that divergence hitchhiking can generate large regions of differentiation, but that the conditions under which this occurs are limited, and that speciation may often require multifarious selection acting on many, isolated and physically unlinked genes.

TLDR
This issue draws upon empirical studies in plants and animals, and theoretical work, to review and further document patterns of genomic divergence, and points to how experimental work is now required to move the field from descriptive studies of patterns of divergence towards a predictive framework that tackles the causes and consequences of genome-wide patterns.
THE EFFICACY OF DIVERGENCE HITCHHIKING IN GENERATING GENOMIC ISLANDS DURING ECOLOGICAL SPECIATION
TLDR
The results show that divergence hitchhiking can generate large regions of differentiation, but that the conditions under which this occurs are limited, suggesting that speciation may often require multifarious selection acting on many, isolated and physically unlinked genes.
