Two mechanisms have been advanced for the origin of reproductive isolation between species. Muller (1939), dealing in the main with barriers to crossing in the later stages of species divergence, such as hybrid inviability and infertility, suggests that these arise almost by chance as a product of change in the genetic background either by genetic drift or as adaptation to different biological situations. This would lead to accelerating divergences as the process continues. or, as Muller puts… 

SELECTION FOR SEXUAL ISOLATION IN DROSOPHILA MELANOGASTER BY A MODIFICATION OF KOOPMAN'S METHOD

A selection experiment for sexual isolation in Drosophila melanogaster using X-ray treatment as well as a device to modify the selection method originally used by Koopman (1950) is concerned.

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.

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.

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.

NATURAL SELECTION FOR REPRODUCTIVE ISOLATION IN PHLOX

The term "Wallace effect" has been applied to shifts in population structure whose primary adaptations are to strengthen reproductive isolating barriers and could permit the two species more efficiently to exploit their habitats.

SPECIATION IN BUTTERFLIES OF THE PAPILIO GLAUCUS GROUP. I. MORPHOLOGICAL RELATIONSHIPS AND HYBRIDIZATION

The ecological and phylogenetic relationships of the tiger swallowtail butterflies comprising the Papilio glaucus group, a morphologically compact group of closely related species limited to North America, are investigated.

CHANGES IN MATING BEHAVIOR PRODUCED BY SELECTION FOR ETHOLOGICAL ISOLATION BETWEEN EBONY AND VESTIGIAL MUTANTS OF DROSOPHILA MELANOGASTER

This study corrects this ommission by combining Dobzhansky's theory and Muller's 'reinforcement' on ethological isolating mechanisms in animals.

A two-sex polygenic model for the evolution of premating isolation. I. Deterministic theory for natural populations.

A specific model is put forward in which mating behavior is determined by additive gene contributions in both sexes, and the strength of mating attraction is maximized when mating "scores" in the two sexes are equalized.

Natural Selection for the Origin of Reproductive Isolation

It is shown that, by means of selection over a period of some 70 generations, ethological isolation can be constructed where none had existed previous to initiation of selection for it.

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

MATING OF EBONY VESTIGIAL AND WILD TYPE DROSOPHILA MELANOGASTER IN LIGHT AND DARK

The result of matings using males from ebony, vestigial and wild type stocks under different illuminations shows that the mating behavior of homozygous males depends on whether matings are carried out in the light or the dark, and that this affects th-eir fitness.

ENVIRONMENT SELECTION BY DROSOPHILA MUTANTS

In the development of the mathematical theory of evolution, the environment is normally treated as uniform and the behaviour of various mutants in respect to it is discussed simply in terms of a coefficient of selection by which each mutant is characterised.

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.

INTERSPECIFIC RELATIONSHIPS WITHIN THE GUARANI GROUP OF DROSOPHILA

The guarani group of Drosophila was first recognized as a species group by Dobzhansky and Pavan (1943). Three new species, guarani, quar« and guaramum' described in their paper, and a fourth species,

Sexual Isolation between Drosophila persimilis and Drosophila pseudoobscura

Results indicate that the high degree of sexual isolation between these two species is primarily due to the behavior of the females.
