In a paper published seven years ago in this journal (Coyne and Orr 1989a), we analyzed the time course of speciation in Drosophila by correlating electrophoretic genetic distance between pairs of species (a number roughly proportional to their divergence time) with the strength of reproductive isolation between them. That analysis yielded five conclusions. First, both prezygotic and postzygotic reproductive isolation increase with divergence time between taxa. Second, prezygotic (sexual… 

How Often Does Sympatry Affect Sexual Isolation in Drosophila?

The Coyne and Orr (1989, 1997) data sets clearly show that sympatry influences prezygotic isolation, the frequency with which interactions among sympatric taxa cause increases in prezyGotic isolation is not clear and the comparative method may be used to estimate more accurately the frequency of increases.

Rapid sexual and genomic isolation in sympatric Drosophila without reproductive character displacement

Speciation in the Drosophila athabasca species complex is at least an order of magnitude older than previously assumed, and it is suggested that these semispecies should be given full species status and adopted new nomenclature.

A BIOGEOGRAPHIC GENETIC APPROACH FOR TESTING THE ROLE OF REINFORCEMENT: THE CASE OF DROSOPHILA PSEUDOOBSCURA AND D. PERSIMILIS

More parsimonious explanations such as reinforcement without genetic exchange (model II) and ecological differentiation, which require high levels of preexisting reproductive isolation between populations, are suggested.

The molecular basis of speciation: from patterns to processes, rules to mechanisms

A new ‘hierarchical faster-sex’ theory is proposed: the rapid evolution of sex and reproduction-related genes (SRR) genes in combination with the preferential involvement of the X-chromosome (hemizygous X-effects) and sexually selected male traits (faster-male evolution).

Divergence and Reproductive Isolation in the Early Stages of Speciation

A study of patterns of phenotypic divergence and premating and postmating isolation between populations of the grasshopper Chorthippus parallelus suggests that the potential of a taxon to exercise mate choice may affect the types of factor that promote speciation in that group.

Reproductive isolation among allopatric Drosophila montana populations

Investigation of barriers among allopatric populations of Drosophila montana found premating (sexual) isolation was particularly strong in crosses involving males from one of the study populations, and it was experimentally demonstrated that the majority of eggs produced were unfertilized.

THE ACCUMULATION OF REPRODUCTIVE INCOMPATIBILITIES IN AFRICAN CICHLID FISH

The results suggest divergent ecological adaptations may prevent populations from interbreeding and help maintain cichlid species diversity, which may be vulnerable to environmental degradation.

MOLECULAR CORRELATES OF REPRODUCTIVE ISOLATION

A novel analysis of published data is presented, demonstrating that pre- and postmating isolation of Drosophila species are more tightly correlated with allozyme divergence than with silent DNA divergence, providing broad support for a model of selection-mediated allopatric speciation.

ON THE COYNE AND ORR‐IGIN OF SPECIES: EFFECTS OF INTRINSIC POSTZYGOTIC ISOLATION, ECOLOGICAL DIFFERENTIATION, X CHROMOSOME SIZE, AND SYMPATRY ON DROSOPHILA SPECIATION

The pervasiveness of the reinforcement pattern and the commonness of range overlap for close relatives indicate that speciation in Drosophila is often not purely allopatric, and no statistically significant effects are found associated with X chromosome size or coarse quantifications of intrinsic postzygotic isolation or ecological differentiation.

THE RATE TEST OF SPECIATION: ESTIMATING THE LIKELIHOOD OF NON‐ALLOPATRIC SPECIATION FROM REPRODUCTIVE ISOLATION RATES IN DROSOPHILA

  • 2014
A new “rate test of speciation” is developed that estimates the likelihood of non‐allopatric speciation given the distribution of RI rates in allopatry versus sympatry, and shows how using RI measures can greatly inform us about the geographical mode of Speciation in nature.

FURTHER EVIDENCE ON SEXUAL ISOLATION WITHIN DROSOPHILA ATHABASCA

This paper presents additional evidence that the widely distributed North American species Drosophila athabasca is divided by sexual isolation.

SPECIATION BY REINFORCEMENT OF PREMATING ISOLATION

  • L. LiouT. Price
  • Biology

Computer simulations and a multilocus genetic model are used to reevaluate the theory of reinforcement and consider the evolution of female preferences for a male secondary sexual trait and the likelihood of extinction is lowered.

GENETIC DIFFERENTIATION DURING THE SPECIATION PROCESS IN DROSOPHILA

The question, "how much genetic differentiation occurs in the process of speciation," must be unfolded into two separate questions concerning the two stages of the process, and the genetic differentiation occurring between allopatric populations that are likely to give rise to different species if and when they become, at least partially, sympatric.

Mitochondrial DNA variation among the Drosophila athabasca semispecies and Drosophila affinis.

Morphology, allozymes, and levels of postreproductive isolation indicate that the semispecies of Drosophila athabasca are as recently diverged as typical populations within a Drosophila species.

Speciation driven by natural selection in Drosophila

The results suggest that females of D. pseudoobscura evolved increased sexual isolation from their sibling species, D. persimilis, by natural selection against maladaptive hybridization.

Speciation by reinforcement: a model derived from studies of Drosophila.

It is suggested that an increase in the level of female mating discrimination can yield reinforcement without further divergence of either male characters or female preferences, and selection on mating discrimination is a viable mechanism for reinforcement and may allow speciation under less stringent conditions than selection on female preference.

A Theoretical Investigation of Speciation by Reinforcement

A closer examination of the reinforcement model of speciation using a computer simulation reveals that there are a number of implicit assumptions necessary for reinforcement to work, suggesting that speciation by reinforcement is not nearly as prevalent as much of the biological literature suggests.

CYTOGENETIC RELATIONSHIPS OF THREE SIBLING SPECIES OF THE DROSOPHILA KIKKAWAI COMPLEX

The data suggest that D. bocki is the most genetically isolated, although all are morphologically indistinguishable, in D. kikkawai and D. leontia, indicating that they have diverged recently from a common ancestor.

PATTERNS OF SPECIATION IN DROSOPHILA

To investigate the time course of speciation, literature data is gathered on 119 pairs of closely related Drosophila species with known genetic distances, mating discrimination, strength of hybrid sterility and inviability, and geographic ranges to provide a cross‐section of taxa at different stages ofSpeciation.

EVOLUTIONARY IMPLICATIONS OF DNA DIVERGENCE IN THE DROSOPHILA OBSCURA GROUP

Using DNA–DNA hybridization, the degree of single‐copy DNA (scDNA) divergence among eight species of the Drosophila obscura group is determined and there is some indication that scDNA in the obscURA group may be evolving considerably slower than in the melanogaster subgroup.
