Hybridization has many and varied impacts on the process of speciation. Hybridization may
slow or reverse differentiation by allowing gene flow and recombination. It may accelerate …

As Abbott et al.(2013) emphasize, hybridization occurs almost inevitably during speciation.
Moreover, studying patterns of introgression across the genome, and the spatial structure of …

Theoretical studies of speciation have been dominated by numerical simulations aiming to
demonstrate that speciation in a certain scenario may occur. What is needed now is a shift in …

Sexual selection has been widely implicated as a driver of speciation. However, allopatric
forms are often defined as species based on divergence in sexually selected traits and it is …

The pattern of greater species mating discrimination between sympatric taxa than between
allopatric taxa has been attributed to the strengthening of mate discrimination to avoid …

We examined causes of speciation in asexual populations in both sympatry and parapatry,
providing an alternative explanation for the speciation patterns reported by Dieckmann and …

A remarkable suite of forms of genomic conflict has recently been implicated in speciation.
We propose that these diverse roles of genomic conflict in speciation processes can be …

Theoretical studies have suggested that the evolution of habitat (host) races, regarded as a
prelude to sympatric speciation, requires strong trade‐offs in adaptation to different habitats …

Hybrid zones have been promoted as windows on the evolutionary process and as
laboratories for studying divergence and speciation. Patterns of divergence between …

Coupling has emerged as a concept to describe the transition from differentiated
populations to newly evolved species through the strengthening of reproductive isolation …
