A set of experiments is described that tests the general hypothesis that sympatric speciation is genetically feasible whenever reproductive isolation evolves indirectly as a correlated character. We specifically test the hypothesis that disruptive selection on habitat preference can lead to sympatric speciation when individuals mate locally within their selected habitat. Drosophila melanogaster was used as a model system. A 35‐generation experiment using a complex habitat maze led to complete… Expand
MOLECULAR CORRELATES OF REPRODUCTIVE ISOLATION

TLDR
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. Expand
Conditions for sympatric speciation: A diploid model incorporating habitat fidelity and non-habitat assortative mating
TLDR
A multilocus model in which genes of all three types of genes of sympatric speciation are considered simultaneously is described, showing that speciation occurs in complete sympatry under a broad range of conditions. Expand
Rapid experimental evolution of reproductive isolation from a single natural population
TLDR
It is shown that experimental evolution of parasite body size over 4 y leads to reproductive isolation in natural populations of feather lice on birds, effectively demonstrating how natural selection can cause species to form. Expand
Sexual selection can constrain sympatric speciation
  • M. Kirkpatrick, S. Nuismer
  • Biology, Medicine

  • 2004
TLDR
This work shows that assortative mating may often generate stabilizing sexual selection, and it shows that this effect can substantially impede sympatric speciation. Expand
Does adaptation to different diets result in assortative mating? Ambiguous results from experiments on Drosophila
TLDR
The results imply that divergent adaptation can result in differences in mating propensity or competitive ability, which, in turn, may either facilitate or hamper speciation depending on the relative frequency of high‐ vs. low‐competition settings in natural habitats of the diverging populations. Expand
Assortative Mating in Drosophila Adapted to a Microsite Ecological Gradient
TLDR
Genetic heterogeneity in mate choice was found among the isofemale lines of D. melanogaster and D. simulans inhabiting Nahal Oren canyon, and significant assortative mating was found in both species. Expand
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
Speciation by Natural and Sexual Selection: Models and Experiments
TLDR
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. Expand
Trapped by habitat choice: Ecological trap emerging from adaptation in an evolutionary experiment
TLDR
The first experimental evidence of an emerging trap is provided: the initial choice of cucumber over tomato remained, however, this choice became maladaptive as tomato ensured a higher fitness at the end of the experiment. Expand
LABORATORY EXPERIMENTS ON SPECIATION: WHAT HAVE WE LEARNED IN 40 YEARS?
TLDR
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. Expand

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

TLDR
These findings caution against using a single component of the process of host selection as indicative of the probability that a particular resource will be utilized in the field, and they bear on the question of how speciation based on genetic variation for host selection may be accomplished.

ECOLOGICAL FACTORS IN SPECIATION
TLDR
It is more important to determine the respective roles of geographical and ecological factors in speciation, and to find out whether they operate consecutively or concomitantly, than to consider the role of sympatric speciation. Expand
PLEIOTROPY AND PARAPATRIC SPECIATION.

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. Expand
The Probability of Isolation by Disruptive Selection

Conditions are discussed that may affect the probability of reproductive isolation developing in laboratory disruptive-selection experiments, and only two stocks were suitable for assessing the capacity of natural populations to respond to disruptive selection by producing isolation. Expand

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
