We initiated 17 laboratory populations of Drosophila simulans: a heterogeneous, chromosomally monomorphic base population (BASE) from which the other 16 were derived; four pairs of selection lines, each pair of which was selected for three different traits in three successive years; and eight genetic-drift lines, each of which experienced six flush-crash cycles after an initial founder event. Every 6 mo for 3 yr we performed tests for reproductive isolation among the selection lines and BASE… 

Forty years of solitude: life‐history divergence and behavioural isolation between laboratory lines of Drosophila melanogaster

Two lines of Drosophila melanogaster that were isolated more than 40 years ago have evolved differences in life‐history characters, or have begun to evolve behavioural or postzygotic isolation.

Drift and selection entwined: asymmetric reproductive isolation in an experimental niche shift

Strong selection in the derived (corn) population appears to have decreased population size to the extent that genetic drift led to the fixation of deleterious alleles that reduced corn-evolved male fitness, and asymmetric pre-mating isolation arose because of this drift-induced maladaptation.

FOUNDER‐FLUSH SPECIATION IN DROSOPHILA PSEUDOOBSCURA: A LARGE‐SCALE EXPERIMENT

The results do not support the claim that the founder‐flush‐crash model identifies conditions very likely to result in speciation events, and it is concluded that although founder events may occasionally lead to the evolution of assortative mating and hence to speciation, the claims are not supported.

Assortative Mating in Drosophila Adapted to a Microsite Ecological Gradient

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.

SINGLE FOUNDER‐FLUSH EVENTS AND THE EVOLUTION OF REPRODUCTIVE ISOLATION

Results indicate that none of 50 independent founder‐flush lines evolved significant assortative mating relative to the control population, which suggests a diminished emphasis on population bottlenecks in speciation of D. melanogaster and perhaps in general.

SERIALLY BOTTLENECKED LINES OF THE HOUSEFLY

This study documents nondebilitating differentiation in the courtship repertoire that can account for divergent mating propensities and premating isolation in houseflies.

Genetic drift promotes and recombination hinders speciation on a holey fitness landscape

The results suggest a novel mechanism by which genetic drift promotes and recombination hinders speciation, and two population genetic parameters that influence the rate of accumulation of genetic incompatibilities: recombination probability and population size.

Laboratory environments are not conducive for allopatric speciation

It is suggested that allopatric speciation experiments are more likely to yield conclusive results under divergent selection than under drift, and points to the benefits of large populations and many generations.

POSTMATING ISOLATION ANALYSIS IN FOUNDER‐FLUSH EXPERIMENTAL POPULATIONS OF DROSOPHILA PSEUDOOBSCURA

A detailed analysis intended to detect postmating barriers in experimental populations of Drosophila pseudoobscura obtained through nine founderflush cycles found that the evolution of premating barriers, as shown by two of these populations, is not necessarily accompanied by the Evolution of postmates ones.

Although rare, founder speciation can have a disproportionate importance in adaptive innovation and radiation, and examples are given to show that "rare" does not mean "unimportant" in evolution.

Mating Choice in Crosses between Geographic Populations of Drosophila pseudoobscura

The literature was reviewed to find tests of mating behavior in crosses between allopatric strains of Droso-phila species and crosses between subspecies were excluded, since in Drosophila, unlike many other animal groups, named subspecies are likely to be well advanced toward full speciation.

GENETIC STUDIES ON SEXUAL ISOLATION AND HYBRID STERILITY IN LONG‐TERM CAGE POPULATIONS OF DROSOPHILA MELANOGASTER

The authors' earlier paper dealt with multifactorial tests on pre-and post-mating isolating mechanisms in Drosophila melanogaster, and experimental evidence that sexual isolation among the subspecies of Dosophila paulistorum is controlled by factors distributed over all the chromosomes.

A computer model of speciation by founder effects

A computer model of a two-locus genetic system with epistatic selection was used to investigate factors influencing the probability of the origin of reproductive isolation, and it was concluded that it is unlikely to be a major cause of rapid speciation, although it could be a contributory factor.

The Genetics of Speciation at the Diploid Level

It is advanced that a diploid species has two differing systems of genetic variability, and speciation may occur as selection operates on the perturbed genetic system to organize new coadapted closed systems which come to characterize the new species.

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.

Effects of population size and selection intensity on responses to disruptive selection in Drosophila melangaster.

The overall isolation index was significant, indicating a real tendency to assortative mating, and one of the replicates showed, in contrast with expectation and the high number, high selection intensity treatment, a significant tendency to disassortive mating.

Breeding Structure of Populations in Relation to Speciation

There is no one rule either with respect to cross-sterility or to other characters in the process of speciation, and in some cases the most significant differences seem to be in chromosome number and organization.

Pupation site selection inDrosophila simulans

Pupation height may have been refractory to artificial selection because of an adaptation of this species to pupate on the larval food source.

Variation in the mating rates of different female genotypes would seem to play as important a role in intersexual selection as sexual responsiveness to particular male traits (e.g., sexual preferences).
