Speciation has a central place in evolution, linking genetic processes within populations to the generation of biological diversity. The formation of new species must involve the evolution of barriers to gene flow within existing species, but how these barriers arise remains a problem. In the case of prezygotic isolation it is possible that natural selection directly favours characters that decrease gene flow. Where two populations have diverged to such an extent that they produce unfit hybrids… Expand
Reinforcement as an initiator of population divergence and speciation
TLDR
How this process can occur, the conditions under which it is most likely to occur, and the empirical data needed to evaluate the hypothesis that reinforcement can initiate speciation are described are described. Expand
Speciation via species interactions: the divergence of mating traits within species.
TLDR
This work argues that RCD (and hence potentially speciation) among populations can be generated by a variety of fundamental species interactions beyond reinforcement, and unifies these interactions under one process of mating trait divergence and speciation ('RCD speciation'). Expand
Speciation driven by natural selection in Drosophila
TLDR
The results suggest that females of D. pseudoobscura evolved increased sexual isolation from their sibling species, D. persimilis, by natural selection against maladaptive hybridization. Expand
Recombination suppressors and the evolution of new species
TLDR
It is shown that in both the Felsenstein (1981) and Kirkpatrick (1982) models, a recombination suppressor is able to enhance the processes leading to speciation and increase its own frequency in the population. Expand
Temporal Separation and Speciation in Periodical Cicadas
TLDR
This natural experiment involves the periodical cicadas of eastern North America, a group in which populations have become isolated in time and space and appear to have evolved into distinct genetic lineages. Expand
Population genetic keys to speciation
TLDR
A general result on the joint evolution of underdominance in tness and positive assortative mating is used to evaluate the signicance of hybrid disadvantage and prezygotic incompatibility in speciation. Expand
Reproductive isolation driven by the combined effects of ecological adaptation and reinforcement
TLDR
These findings demonstrate the joint effects of reinforcement, ecological adaptation and gene flow on progress towards speciation in the wild in Timema cristinae walking-stick insects. Expand
Selfish genetic elements and speciation
TLDR
It is concluded that although some of the case studies are tantalizing, particularly those associated with Wolbachia, the role of selfish genetic elements in speciation remains unproven. Expand
A sexually selected character displacement in flycatchers reinforces premating isolation
TLDR
In populations where two species coexist, it is shown that female choice selects for a divergence in male plumage colour and that the resulting character displacement reduces the frequency of hybridization. Expand
Pervasive reinforcement and the role of sexual selection in biological speciation.
TLDR
It is shown that in birds, divergence in song and plumage in allopatry corresponds poorly with whether species mate assortatively in hybrid zones and argued that many other factors besides trait divergence affect propensity to hybridize, including rarity of conspecific mates and choice based on territory rather than male traits.

Genetic Revolutions, Founder Effects, and Speciation
TLDR
It is argued that, although founder effects may cause speciation under sufficiently stringent conditions, they are only one extreme of a continuous range of possibilities, and divergence may be driven in a variety of ways, without the need for drastic external changes. Expand
A Theoretical Investigation of Speciation by Reinforcement
TLDR
A closer examination of the reinforcement model of speciation using a computer simulation reveals that there are a number of implicit assumptions necessary for reinforcement to work, suggesting that speciation by reinforcement is not nearly as prevalent as much of the biological literature suggests.

Genetic Revolutions in Relation to Speciation Phenomena: The Founding of New Populations
As a dynamic process of genetic change, evolution manifests itself in two ways: It produces adaptive characters, and it produces species. To recognize that evolution has occurred by studying theseExpand
DISRUPTIVE SELECTION ON HABITAT PREFERENCE AND THE EVOLUTION OF REPRODUCTIVE ISOLATION: A SIMULATION STUDY
  • W. Rice
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 1984
TLDR
It is suggested that environmental conditions which produce disruptive selection on habitat preference represent a special case in which sympatric speciation is particularly likely to occur. Expand
Evolution in closely adjacent plant populations
TLDR
It is invalid to conclude that a monotonic cline for reproductive isolation gives a priori evidence of its evolution in allopatry, but the existence of inverse clines in isolating mechanisms strongly suggests the evolution of isolation in sympatry. Expand
Hybrid Zones and Homogamy in Australian Frogs
TLDR
In spite of much theoretical deliberation and conjecture, thoroughly worked natural examples, specifically directed at evolutionary aspects of homogamic mechanisms, remain inadequate. Expand
RAPID ORIGIN OF SEXUAL ISOLATION AND CHARACTER DIVERGENCE IN A CLINE
  • R. Lande
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 1982
TLDR
Mechanisms for clinal speciation first outlined in genetic terms by Fisher (1930) are reinvestigated and the latter mechanism is potentially much more powerful for initiating sexual isolation and character divergence along a cline than is selection against hybridization. Expand
Evolution in closely adjacent plant populations IV. Barriers to gene flow
TLDR
Since no evidence has been presented for the origin of breeding barriers under disruptive selection in natural populations, the occurrence of mechanisms reducing gene flow were investigated in closely adjacent plant populations at metal mine boundaries. Expand
Non-Allopatric Speciation in Animals
TLDR
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
STILL ANOTHER ATTEMPT TO ACHIEVE ASSORTATIVE MATING BY DISRUPTIVE SELECTION IN DROSOPHILA
  • E. Spiess, C. Wilke
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 1984
TLDR
It is postulated that selection of mated pairs for the sum of their joint bristle numbers would be more efficient than previous experiments in obtaining contributions of both sexes toward the morphological trait and thus toward any assortative preference, provided that genetic variation was available for preferential mating.
