The tradition of classifying cases of speciation into discrete geographic categories (allopatric, parapatric and sympatric) fuelled decades of fruitful research and debate. Not surprisingly, as the science has become more sophisticated, this simplistic taxonomy has become increasingly obsolete. Geographic patterns are now reasonably well understood. Sister species are rarely sympatric, implying that sympatric speciation, it its most general sense, is rare. However, sympatric speciation, even in… Expand
Sympatric speciation without borders?
TLDR
The biogeography of speciation remains a controversial issue and the process of allopatric speciation reigns, so Crow et al. (2010) challenge us to expand the definition of sympatric Speciation by studying species of marine fishes that they propose have arisen by sympatrics speciation in a setting that does not appear to conform to the usual geographical criteria.

Searching for Sympatric Speciation in the Genomic Era.
TLDR
Tory differences among different types of sympatric speciation and speciation-with-gene-flow models are reviewed and summarized, and genomic analyses are proposed for distinguishing which models apply to case studies based on the timing and function of adaptive introgression. Expand
New criteria for sympatric speciation in the genomic era
TLDR
Criteria for demonstrating sympatric speciation in the face of widespread gene flow is revisited and monophyly is an insufficient criterion; it must take a locus-specific approach to investigate whether any introgression contributed to reproductive isolation. Expand
Are we analyzing speciation without prejudice?
  • K. Johannesson
  • Biology, Medicine
  • Annals of the New York Academy of Sciences
  • 2010
TLDR
A review of 73 recent empirical studies shows that when allopatric speciation is suggested, a nonallopatrics alternative is rarely considered, whereas the opposite is true in studies suggesting sympatric Speciation, indicating a biased treatment of different speciation models. Expand
Contemporary Philosophy and Methods for Studying Speciation and Delimiting Species
Species delimitation is a first step for realizing the extent of biodiversity and is relevant for all downstream applications in biology. The production of large genome-scale datasets for non-modelExpand
Sympatric Speciation in the Post “Modern Synthesis” Era of Evolutionary Biology
TLDR
The evolution of reproductive isolation solely due to natural selection is perhaps the most controversial manner by which sympatric speciation occurs, and it is that which is focused upon in this review. Expand
What do we need to know about speciation?
TLDR
A distillation of questions about the mechanisms of speciation, the genetic basis of speciating and the relationship between speciation and diversity are presented. Expand
Speciation with gene flow on Lord Howe Island
TLDR
It is demonstrated that speciation with gene flow may, in fact, be frequent in some instances and could account for one in five of the endemic plant species of LHI, which challenges current views on the origin of species diversity. Expand
THE LANGUAGE OF SPECIATION
  • R. Harrison
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 2012
TLDR
The origin and evolution of ideas about speciation are viewed through the lens of changing language use, where the introduction of new terminology has failed to recognize historical usage, leading to unnecessary ambiguity and redundancy. Expand
Multispecies Outcomes of Sympatric Speciation after Admixture with the Source Population in Two Radiations of Nicaraguan Crater Lake Cichlids
TLDR
The evolutionary history of two small-scale radiations of Midas cichlids inhabiting crater lakes Apoyo and Xiloá is reconstructed through a comprehensive genomic data set to support a scenario of speciation that was initiated in sympatry and does not result from secondary contact of already partly diverged populations.

Sympatric Speciation: Models and Empirical Evidence
TLDR
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. Expand
THE GEOGRAPHY OF MAMMALIAN SPECIATION: MIXED SIGNALS FROM PHYLOGENIES AND RANGE MAPS
TLDR
The results support skepticism about ARC's power for inferring the biogeography of speciation and propose methodological improvements including changes in the way overlap between clades is quantified and Monte Carlo methods to test the null hypothesis of no relationship between phylogenetic relatedness and geographic range overlap. Expand
Sympatric, parapatric or allopatric: the most important way to classify speciation?
TLDR
It is suggested that it is more productive to study the current balance between local adaptation and gene flow, the interaction between components of reproductive isolation and the genetic basis of differentiation, than the most common classification of modes of speciation, sympatric, parapatric or allopatric. Expand
What, if anything, is sympatric speciation?
TLDR
It is argued that testing whether a case fits a particular definition is less informative than evaluating the biological processes affecting divergence, and that this context can be better understood by modelling and measuring quantities, such as gene flow and selection, rather than assigning cases to discrete categories like sympatric and allopatric speciation. Expand
Space, sympatry and speciation
TLDR
A more precise spatial definition of sympatry is proposed by incorporating the population genetics of dispersal (or ‘cruising range’), which is considerably more likely under this spatial definition than under the demic definition, because distance itself has a powerful structuring effect, even over small spatial scales comparable to dispersal. Expand
Detecting the Geographical Pattern of Speciation from Species‐Level Phylogenies
TLDR
It is found that relatively recent speciation events are characterized by greater asymmetry in range size between sister clades than expected under the null models, providing potential support for the peripatric model of speciation. Expand
Geographic Variation, Speciation and Clines.
TLDR
Professor Endler shows how geographic differentiation and speciation may develop in spite of continuous gene flow, and considers the interpretation of natural clines and the associated geographic patterns of subspecies and species. Expand

TLDR
Comparative data on two endemic species of the palm genus Howea in Lord Howe Island are presented, from which it is inferred that speciation was sympatric — that is, divergence had occurred in the absence of geographic isolation. Expand
Non-Allopatric Speciation in Animals

The extent to which the theory and evidence amassed since 1963 warrant a major change in views of animal speciation is reviewed, and the theory of stasipatric speciation and purported cases of sympatrics associated with a shift to a new host are reviewed. Expand
