Species that do not interbreed because of behavioral differences are described as ethologically or sexually isolated (Dobzhansky, 1951). Ethological isolating mechanisms are well known in animals (Mayr, 1963), but knowledge of the way in which they have evolved is fragmentary. Two theories have been advanced for their origin: Muller (1939) suggested that they arise as by-products of genetic divergence in allopatric populations; Dobzhansky (1940) argued that they are developed and strengthened…

Selection for assortative mating between parapatric subspecies of grasshopper

Sexual isolation in Drosophila. II. Intraspecific variation in mate recognition systems

The results show that a classification of Drosophila species based on SMRS stability, as proposed by the “Recognition concept of species”, is virtually impossible.

SELECTION FOR SEXUAL ISOLATION BETWEEN GEOGRAPHIC FORMS OF DROSOPHILA MOJAVENSIS. II. EFFECTS OF SELECTION OF MATING PREFERENCE AND PROPENSITY

  • H. R. Koepfer
  • Biology
    Evolution; international journal of organic evolution
  • 1987
The study described here begins a "behavioral dissection" of the post-selection isolation between peninsular males and mainland females to elucidate the effects of the selective regimen on mating preference and propensity, or sex drive, and to evaluate the relative importance of these behavioral components for mate choice in the selected and control lines.

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.

Multifaceted, Cross-Generational Costs of Hybridization in Sibling Drosophila species

This work estimated multiple fitness components for F1 hybrids and backcross progeny and used these to compare the relative fitness of parental species and their hybrids across two generations to reveal intense postzygotic selection against hybridization and thus, an enhanced role for reinforcement in the evolution of populations and diversification of species.

Comparative studies of courtship behaviour in sympatric sibling species of Zaprionus (Diptera - Drosophilidae)

  • R. Lee
  • Biology, Environmental Science
  • 1983
The main objects of the project were to study the mechanisms by which members of these two species identify the sex of other individuals (sexual dimorphism being slight); and the isolating mechanisms operating between the two species.

SEXUAL SELECTION BY FEMALE CHOICE IN POLYGYNOUS ANIMALS

Over the last two decades a major resurgence of work on sexual selection has occurred and Evolutionists have reexamined Darwin's ideas and are now much more impressed by their cogency.

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.

Experimental Evolution of Mating Discrimination in Budding Yeast

A test of speciation via sexual selection on female preferences

It is suggested that the inability to achieve true reproductive isolation among some lines could have been due to low evolutionary potential in the ‘shape’ of courtship, as defined by the second principal component.

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

  • S. Kessler
  • Biology
    Evolution; international journal of organic evolution
  • 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.

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.

Mating Propensity and Its Genetic Basis in Drosophila

Three major phenomena may evolve: increasing fertility, or higher fitness for the population or the species, increasing sexual dimorphism owing to intrasexual competition (Darwin’s sexual selection) and to preferences for mates, and increasing assortative mating leading to sexual isolation and speciation.

A GENE MUTATION WHICH CHANGES A BEHAVIOR PATTERN

It is tempting to assume that behavior patterns have evolved in the same manner as other features of animal populations, by the selection of inheritable differences, but it is impossible to be certain, however strong the implication about the evolution of behavior, unless one can demonstrate the existence of 'genetic' variations in behavior upon which selection could act.

Hybrid Sterility as an Isolating Mechanism in the Genus Drosophila

  • L. Ehrman

  • 1962
Within the confines of the genus Drosophila there exists abundant hybrid material, even the crucial borderline cases between races and species, with which one may probe the problems of the bases of hybrid sterility.

MATING CALL AND STAGE OF SPECIATION IN THE MICROHYLA OLIVACEA—M. CAROLINENSIS COMPLEX

Variations in mating call in a species group of narrowmouthed frogs (genus Microhyla) 2 and with the possible evolutionary significance of these variations are dealt with.

Speciation as a Stage in Evolutionary Divergence

A theory is suggested according to which the development of isolating mechanisms follows, rather than accompanies, that of the adaptive complexes themselves, which suggests that speciation is meant the fixation of discontinuity among organisms.

Courtship Behaviour of some Drosophila melanogaster Mutants

A more detailed analysis of the mutants studied by Hotta and Benzer is of interest because some other body colour mutants, however, such as black, show normal ERGs, suggesting that body colour abnormality and defective ERG are unrelated.

REVERSIBILITY IN EVOLUTION CONSIDERED FROM THE STANDPOINT OF GENETICS 1

It is inferred that evolution proceeded contrary to the prevailing mutation pressure, and hence only by the aid of selection, and a certain reverse evolution would tend to occur, so far as individual loci were concerned.
