Natural selection acts to build and reinforce barriers to gene exchange between populations whose hybridization results in reproductive wastage (Dobzhansky 1970). This has been demonstrated experimentally by Koopman (1950), Wallace (1954), Knight, Robertson, and Waddington (1956), Kessler (1966), and most recently, by Dobzhansky and Pavlovsky (1971). These last authors have shown that, by means of selection over a period of some 70 generations, ethological isolation can be constructed where… 

ALTERED COMPETITION BETWEEN TWO REPRODUCTIVELY ISOLATED STRAINS OF DROSOPHILA MELANOGASTER

To the knowledge, this research is the first study of simultaneous evolution of premating sexual isolation and altered competitive response of Drosophila melanogaster and competition between larvae of the two strains.

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.

Fourth Report on Natural Selection for the Origin of Reproductive Isolation

The outcome of enforced togetherness, within the limits of genetic variability contained among the strains, should be an enhanced reproductive isolation, a reluctance to mate with individuals of the opposite sex when the product of such mating is sterile offspring.

Critical tests of the origin of pre-zygotic isolation are indispensable in as large of array of taxa as possible to contribute to understanding the process of speciation and the evolutionary future of hybrid zones between parapatric species.

BEHAVIORAL REPRODUCTIVE ISOLATION AMONG POPULATIONS OF THE ROTIFER BRACHIONUS PLICATILIS

While there is still disagreement about the evolutionary dynamics of how reproductive isolation develops, the existence of reproductive isolation in many groups is well documented and it is generally agreed that behavioral reproductive isolation plays a premier role in animal speciation.

DISRUPTIVE SELECTION AND ASSORTATIVE MATING IN TRIBOLIUM CASTANEUM

Experimental studies of disruptive selection have shown that disruptive selection can increase phenotypic and genetic variability, and under what circumstances can disruptive selection lead to prezygotic reproductive isolation.

The failure to obtain sexual isolation by artificial selection

It is hypothesize that the number of genes controlling sexual selection or isolation is small and that polymorphism for these genes varies from one strain to another.

CHARACTER DISPLACEMENT FOR SEXUAL ISOLATION BETWEEN DROSOPHILA MOJAVENSIS AND DROSOPHILA ARIZONENSIS

Evidence for reproductive character displacement in natural populations is poor and controversial, and it is felt that many of these problems could be avoided if one could demonstrate character displacement for sexual isolation.

Review Lecture Disruptive selection

  • 1972
Disruptive selection has been shown to be capable of increasing phenotypic and genetic variance, of producing and maintaining polymorphisms, of causing divergence of sub-populations between which substantial gene exchange occurs, and of splitting a population into two which are genetically isolated from one another.

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.

NATURAL SELECTION FOR REPRODUCTIVE ISOLATION BETWEEN DROSOPHILA PSEUDOOBSCURA AND DROSOPHILA PERSIMILIS

One of the most imiportant problems in the study of speciation has been that of the origin of reproductive isolating mechanisms, for it is by the building up of intrinsic barriers which prevent gene

SELECTION FOR SEXUAL ISOLATION WITHIN A SPECIES

The mechanism proposed by Dobzhansky (1937) is that when sufficient divergence between two species has arisen so that the hybrids are less well adapted for any available habitat than either parental type, there will be selection for sexual isolation.

SELECTION FOR AND AGAINST ETHOLOGICAL ISOLATION BETWEEN DROSOPHILA PSEUDOOBSCURA AND DROSOPHILA PERSIMILIS

  • 1966
An attempt is made to weaken as well as to strengthen the ethological isolation between two closely related species; and progress in selection is measured in the two sexes of each species separately, so that differential effects become apparent.

A STUDY OF SEXUAL ISOLATION BETWEEN CERTAIN STRAINS OF DROSOPHILA PAULISTORUM

It appears to be a general rule that where two or more of the incipient species are sympatric in the same territory, no hybrids between them are formed spontaneously, and crosses can be made in laboratory experiments only with considerable difficulty, always yielding sterile hybrids.

DIRECT OBSERVATION OF SEXUAL ISOLATION BETWEEN ALLOPATRIC AND BETWEEN SYMPATRIC STRAINS OF THE DIFFERENT DROSOPHILA PAULISTORUM RACES

Drosophila paulistorum is indeed a superspecies composed of six races or subspecies or incipient species, and this situation is of interest precisely because these six may be considered about equally legitimately as very distinct races or as very closely related species.

Experimentally Created Incipient Species of Drosophila

By means of selection in many generations, ethological (sexual) isolation has been built between strains of Drosophila which were formerly not reproductively isolated.
