Since Darwin first proposed that new species could arise without geographic separation, biologists have debated whether or not divergence occurs in the presence of gene exchange. Today we understand that new species can diverge while exchanging genes, depending on the strength of disruptive natural selection and the factors that affect the linkage relationships of genes under disruptive selection. This mode of diversification—divergence with gene flow—includes sympatric speciation, in which…

Both speciation and population-genetic models that make explicit predictions about how the rate of recombination influences patterns of genetic variation within and between species are reviewed and empirical data of DNA sequence variation in rabbits and mice is compared.

Genomic heterogeneity of historical gene flow between two species of newts inferred from transcriptome data

This study demonstrates the complexity of long‐term gene flow between distinct but incompletely reproductively isolated taxa which divergence was initiated millions of years ago and found evidence for genomic heterogeneity of interspecific gene flow.

This work proposes combining two types of genetic analysis focused on this key early stage of the speciation process to identify the selective agents directly responsible for population divergence.

Speciation with Gene Flow in North American Myotis Bats

PHRAPL, a new tool for phylogeographic model selection, is utilized to compare the fit of a broad set of demographic models that include divergence, migration, or both among Myotis evotis, M. thysanodes and M. keenii, providing a striking example of speciation‐with‐gene‐flow in an evolutionary lineage.

Can genomic data alone tell us whether speciation happened with gene flow?

To resolve the central issue of speciation, other forms of observations such as the sequencing of reproductive isolation genes or the identification of geographical barrier(s) will be necessary.

Modeling the multiple facets of speciation-with-gene-flow towards improving divergence history inference of a recent fish adaptive radiation.

This study provides a new retrospective insight into the historical demographic and selective processes that shaped a continuum of divergence associated with ecological speciation and illustrates the efficiency of the newly developed models towards improving the understanding of historical events in the process of adaptive evolution and speciation in any other species complex.

Ten years of demographic modelling of divergence and speciation in the sea

These studies show that geographical barriers to gene flow do exist in the sea but that divergence can also occur without strict isolation, implying that gene flow between diverging taxa is possible at higher levels of divergence than previously thought.

Defining Species When There is Gene Flow.

It is suggested that contrasting long-term migration rate and short-term hybridization rate, both of which can be estimated using genetic data, may be a powerful approach to detecting the presence of reproductive barriers and to define species boundaries.

Shallow evolutionary divergence between two Andean hummingbirds: Speciation with gene flow?

It is hypothesized that speciation likely occurred in the face of gene flow, driven by other ecological pressures or by sexual selection, and makes C. helianthea and C. bonapartei an appropriate system in which to search for the genetic basis of species differences employing genomics.

On the relative ease of speciation with periodic gene flow

A simple model of speciation through Bateson-Dobzhansky-Muller incompatibilities in the face of periodic gene flow is developed and it is found speciation occurs much faster under periodic than constant gene flow with equivalent effective migration rates.



A new approach to estimate parameters of speciation models with application to apes.

A new Markov chain Monte Carlo method is developed to estimate parameters of an isolation-migration model that suggests that the two chimpanzee species became reproductively isolated in allopatry while Western and Central chimpanzee populations split approximately 440 Kya but continued to exchange migrants.

Gene flow and natural selection in the origin of Drosophila pseudoobscura and close relatives.

The principal finding is that the three loci present very different histories, with Adh indicating large amounts of recent gene flow among the taxa, while little or no gene flow is apparent in the data from the other loci.


The role of geographical separation in generating allopatry has been overemphasized in the past and its role in generating diminished gene flow in combination with strong, discontinuous, and multifarious divergent selection, has been largely unappreciated.

Inferring the history of speciation from multilocus DNA sequence data: the case of Drosophila pseudoobscura and close relatives.

There is a good correspondence between the genomic regions associated with reproductive isolation and the regions that show little or no evidence of gene flow, and a model in which D. pseudoobscura and D. persimilis have exchanged genes at some loci is supported.

Sympatric Speciation: Models and Empirical Evidence

It is now generally accepted that sympatric speciation has occurred in at least a few instances, and is theoretically plausible, and progress is being made on evaluating the empirical validity of key theoretical conditions for sympatrics speciation.

Multilocus Methods for Estimating Population Sizes, Migration Rates and Divergence Time, With Applications to the Divergence of Drosophila pseudoobscura and D. persimilis

A Markov chain Monte Carlo method for estimating the posterior probability distribution of model parameters is applied to a large multilocus data set from Drosophila pseudoobscura and D. persimilis, with considerable variation in gene flow estimates among loci, in both directions between the species.

Recombination and speciation

It is argued that ideas about the role of recombinations in speciation should be considered in the context of the variability of recombination rates and patterns more generally and that genic as well as chromosomal causes of restricted recombination should be consideration.

Chromosomal inversions and the reproductive isolation of species

It is suggested that inversions create linkage groups that cause sterility to persist between hybridizing taxa, and natural selection will have a greater opportunity to decrease the frequency of interspecies matings.

Speciation by Natural and Sexual Selection: Models and Experiments

It is shown that the geographical context of speciation can be viewed as a form of assortative mating and this provides a framework for interpreting results from laboratory experiments, which are found to agree generally with theoretical predictions about conditions that are favorable to the evolution of prezygotic isolation.

Hybrid zones and the genetic architecture of a barrier to gene flow between two sunflower species.

The utility of hybrid zones for identifying factors contributing to isolation and the prediction of increased resolution relative to controlled crosses are demonstrated and verified.
