The general applicability of two models used in predicting evolutionary directions from asymmetry in reproductive isolation was tested in the laboratory. In mate preference tests with strains of Drosophila melanogaster whose ancestral and derived relationships were known, no correspondence was found between sexual isolation and direction of evolution. 

Behavioral Phylogenies and the Direction of Evolution

A model for using mate preference data to deduce the direction of evolution between populations related by founder events or population bottlenecks is examined. Data from a wide range of organisms

Role of sexual behaviours in sexual isolation in Drosophila

The conclusion arrived at is that courtship behaviour is very stable from an evolutionary point of view, and it is difficult to accept that changes in this trait can propitiate speciation in Drosophila.

Founder effects and the evolution of asymmetrical sexual isolation in a rapidly-speciating clade

Kaneshiro's hypothesis suggests that divergence in sexual characters between populations may arise in allopatry when 'derived' founding populations are subject to severe population bottlenecks, accompanied by a relaxation of sexual selection relative to 'ancestral' source populations.

In an attempt to gain insight into the process of the development of reproductive isolation, eight populations of Drosophila pseudoobscura were studied

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.

EXPERIMENTAL SEARCH FOR SEXUAL ISOLATION IN FLIES

Incipient sexual isolation between two strains of D. metanogaster was tested by male choice experiments and there was an interaction between type of female and duration of time available for mating.

DISENTANGLING THE EFFECTS OF MATING PROPENSITY AND MATING CHOICE IN DROSOPHILA

It is shown that if competing individuals differ in mating propensities and tests are long enough to allow most matings to happen, a spurious sexual isolation can appear, and advises against the application of male and female choice tests to assess intraspecific isolation without a proper knowledge of the matingpropensities of competing individuals.

THE EVOLUTION OF ASYMMETRY IN SEXUAL ISOLATION: A MODEL AND A TEST CASE

A curvilinear relationship between isolation asymmetry and divergence was predicted by the model and was supported by statistical analysis of the salamander data.

Females preferred high-activity males in almost every case and temporary sexual isolation was found between flies of the high and low lines in one of the sets of selection lines.

Correlated responses to selection for a behavioral trait inDrosophila melanogaster

Investigation of other behavioral and structural changes indicated that courtship duration, locomotor activity, and aristal morphology also showed differences between the selected strains.

A genetic analysis of phototactic behavior in Drosophila melanogaster I. Selection in the presence of inversions.

The effectiveness of selection for positive and negative phototactic behavior in populations of Drosophila melanogaster heterozygous for various multiple inversions was compared using the method of realized heritability and the results are discussed in terms of the organization of genes influencing phototact behavior in this species.

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.

The objective of this study is to determine if females from geotactically divergent maze-selected strains of D. melanogaster differ in their utilization of oviposition sites given a choice between a lower and upper (inverted) egg-laying surface.

Sexual Isolation Studies in the Species Complex Drosophila Virilis.

The results of SPENCER and PATTERSON, STONE and GRIFFEN suggest the existence of sexual isolation in the virilis complex similar to that found by DOBZHANSKY and KOLLER in D. athabasca, and the success of the mating was not measured directly, but by the offspring obtained, so that many factors besides sexual isolation were involved.

The theory of speciation via the founder principle.

The genetic transilience model is used to explain several features of the evolution of the Hawaiian Drosophila, and experimental designs are outlined to test the major predictions of the theory.
