A repetition of Thoday and Gibson's experiments with the modification that disruptive selection is applied to a trait, habitat preference, that produces positive assortative mating as a correlated character is described.

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.

Dualism and conflicts in understanding speciation.

New data, mainly from field ecology, molecular population genetics, laboratory studies with Drosophila and computer analysis, all suggest that the isolation theory may no longer be the most desirable vantage point from which to explore speciation.

Sympatric Differentiation and Speciation: Insights from Drosophila Studies

The results suggest that populations inhabiting opposite slopes exemplify ongoing divergence taking place regardless of high migration, and a precise image-bearing expression for the sympatric model: “The Ugly Duckling” is found.

A Dynamical Theory of Speciation on Holey Adaptive Landscapes

The results presented here, together with earlier numerical simulations, strongly suggest that rapid speciation, including simultaneous emergence of several new species, is a plausible outcome of the evolutionary dynamics of subdivided populations.

LABORATORY EXPERIMENTS ON SPECIATION: WHAT HAVE WE LEARNED IN 40 YEARS?

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.

A Century of Evolution : Ernst Mayr ( 1904 – 2005 ) Ernst Mayr and the integration of geographic and ecological factors in speciation

    P. Nosil
    Biology, Environmental Science
  • 2008
This work establishes that, in the absence of gene flow, divergent selection often promotes speciation, and explores the genetic and ecological circumstances that facilitate speciation in the face of gene flow.

Genetic Variation for Habitat Preference: Evidence and Explanations

It is shown theoretically that under hard selection, optimal habitat selection may often lower the probability of maintaining a polymorphism at a locus that affects adaptation to different habitats, and soft selection appears much more likely to promote variation for habitat preference.

Speciation in the sub‐Antarctic weevil genus Dusmoecetes Jeannel (Coleoptera: Curculionidae)

    S. Chown
    Biology, Environmental Science
  • 1990
This study presents a hypothetical speciation scenario, based on current observations, which seems to be consistent with the new model of sympatric speciation, and identifies two morphologically similar, though ecologically separated, species in the Dusmoecetes similis species complex on Marion Island.

MOLECULAR CORRELATES OF REPRODUCTIVE ISOLATION

A novel analysis of published data is presented, demonstrating that pre- and postmating isolation of Drosophila species are more tightly correlated with allozyme divergence than with silent DNA divergence, providing broad support for a model of selection-mediated allopatric speciation.

DISRUPTIVE SELECTION ON HABITAT PREFERENCE AND THE EVOLUTION OF REPRODUCTIVE ISOLATION: A SIMULATION STUDY

    W. Rice
    Biology, Environmental Science
  • 1984
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.

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.

PLEIOTROPY AND PARAPATRIC SPECIATION

    M. Slatkin
    Biology
  • 1982
The potential importance of pleiotropic effects at different loci tend to reinforce each other and can lead to speciation in parapatric populations is investigated by means of a simple model.

A Population Model of Sympatric Speciation

In this chapter, four genetic mechanisms, "habitat selection, pleiotropic genes, modifying genes, and assortative mating genes" which could result in sympatric speciation are presented.

SYMPATRIC HOST RACE FORMATION AND SPECIATION IN FRUGIVOROUS FLIES OF THE GENUS RHAGOLETIS (DIPTERA, TEPHRITIDAE)

    G. Bush
    Biology
  • 1969
The objective of this paper is to point out how the biological attributes of these flies may have permitted new forms to arise rapidly in the absence of geographical barriers to gene flow.

SKEPTICISM TOWARDS SANTA ROSALIA, OR WHY ARE THERE SO FEW KINDS OF ANIMALS?

    J. Felsenstein
    Environmental Science, Biology
  • 1981
In a classic paper, Hutchinson (1959) set the tone for much of the ecological work done during the past 20 years by suggesting that ecologists try to explain the numbers of species of animals by explaining how the species could coexist.

Theoretical Considerations of Sympatric Divergence

Results showed that a polymorphism could be maintained particularly with high levels of selection and/or low levels of gene flow, both in single-gene and polygenic cases.

SELECTION FOR REPRODUCTIVE ISOLATION BETWEEN TWO POPULATIONS OF MAIZE, ZEA MAYS L. ,

    E. Paterniani
    Agricultural and Food Sciences
  • 1969
The present paper deals with the results obtained after selecting for intraspecific reproductive isolation between two varieties of maize and considers the origin of reproductive isolation in plants.

MECHANISMS OF SPECIATION­ A POPULATION GENETIC APPROACH

The purpose of this review is to initiate the discussion absent in White's (234) book and much of the speciation literature and outline why it is important for population genetics and speciation theory to become integrated.

A single locus mass-action model of assortative mating, with comments on the process of speciation

In the hypothesis of speciation where premating isolating mechanisms are supposed to evolve as a response to selection against hybrids, there is some doubt as to whether genetic variation for assortative mating would exist, and whether it would always respond to selection.
