A laboratory stock ofD. silvestris has become partially sexually isolated since its origin from 1 natural population of this species. Evolution of reproductive isolation is probably incidental to reorganization of the genome, particularly the genetics of sexual behavior, following random drift in a small population. 
Sequential Differentiation of Sexual Behavior in Populations of Drosophila silvestris
TLDR
The data obtained from this study provide a basis for inferring the direction of evolution among the six populations of silvestris and suggest that the population on Hualalai is the oldest population, and from there, two separate lineages gave rise to the remaining five populations.
The mating behavior of individuals ofDrosophila pseudoobscura from New Zealand
TLDR
Recently discovered individuals in New Zealand of the North American speciesDrosophila pseudoobscura were analyzed for any divergence in mating behavior and showed no development of sterility between recently caught New Zealand and North American flies.

TLDR
The present results clearly indicate that the laboratory strains of D. ananassae have developed behavioural reproductive isolation as a result of genetic divergence.
The origin of reproductive isolating mechanisms is an important event in the process of speciation: Evidences from Drosophila
TLDR
The origin of reproductive isolating mechanisms is an important event in the process of cladogenesis (speciation), which prevents exchange of genes between Mendelian populations by genetically conditioned mechanisms which are intrinsic to the organisms themselves.
Dynamics of Sexual Selection in the Hawaiian Drosophilidae: A Paradigm for Evolutionary Change
TLDR
The dynamics of sexual selection, i.e. changes within the sexual environment of a population, are reviewed as an important driver of evolutionary change especially during the initial stages of species formation.
An Experiment Testing Two Hypotheses of Speciation
TLDR
The results of this experiment and previous, related ones support the view that either genetic drift or selection is by itself sufficient to produce reproductive isolation as a pleiotropic by-product and help establish sexual isolation in Drosophila simulans.
Sexual selection and incipient speciation in Hawaiian Drosophila
TLDR
Sexual selection experiments to produce strains with high and low mating discrimination in females of laboratory strains of Hawaiian Drosophila indicated that mating discrimination has affected secondary sexual traits of the low-line strain significantly: Cilia number on the foretibia of low- line males is significantly different from that of the standard line, which perhaps was the indication of incipient speciation in Hawaiian Dosophila.
Incipient sexual isolation in thenasuta-albomicans complex ofDrosophila: mating preference in male-, female- and multiple-choice mating experiments
TLDR
This study of evolutionary experimentation on raciation under laboratory conditions has documented the initiation of preference for con-specific matings among closely related and independently evolving members of thenasuta-albomicans complex of Drosophila.
Peripatric speciation
Peripatric speciation is a mode of speciation in which a new species is formed from an isolated peripheral population.[1]:105 Since peripatric speciation resembles allopatric speciation, in that
Speciation processes within the Korean Peninsula based on the mites from the family Zerconidae (Acari: Mesostigmata)
TLDR
A very high level of endemism (over 60%) proves the intensity of the speciation processes within the Zerconidae family on the Korean Peninsula.

Ethological isolation among three species of the planitibia subgroup of Hawaiian Drosophila.
TLDR
The ethological isolation and the hybrid sterility are uncorrelated, expected if premating isolation between closely related species is an ad hoc product of natural selection, while postmating isolation is an incidental result of genetic divergence.

TLDR
The data presented in this paper, measuring the amount of premating reproductive isolation among the four species in "malechoice" experiments, provide basis for the interpretation of phylogenetic relationships of these species.

TLDR
The ethological isolation among six allopatric populations, comprised of two closely related species of Hawaiian Drosophila, was measured and used to analyze the phylogenetic relationships among these populations and found no consistent morphological or cytological differences were detected.
