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

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

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.

The origin of reproductive isolating mechanisms is an important event in the process of speciation: Evidences from Drosophila

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

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.

Sexual selection and incipient speciation in Hawaiian Drosophila

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

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

The existence of peripatric speciation is supported by observational evidence and laboratory experiments, and scientists observing the patterns of a species biogeographic distribution and its phylogenetic relationships are able to reconstruct the historical process by which they diverged.

Indirect thermal selection in Drosophila melanogaster and adaptive consequences

Responses associated with temperature selection in Drosophila melanogaster resulted in two strains, one heat sensitive and another heat resistant, and correlated responses were found for the rate of heat shock protein synthesis, behavioral patterns and fitness components.

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.

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.

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 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.

Ethological isolation among three species of the planitibia subgroup of Hawaiian Drosophila.

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.
