We have used two paralogous genes (Amyrel and Amy) of the amylase multigene family to reconstruct the phylogeny of the nine Drosophila melanogaster subgroup sister species, including D. santomea, the newly discovered endemic from São Tomé island. The evolutionary divergence of these genes is of special interest as it is suspected to result from physiological evolution via gene duplication. This paper describes the relationship between the geographical origin of the various strains and the… 
Multilocus Analysis of Introgression Between Two Sympatric Sister Species of Drosophila: Drosophila yakuba and D. santomea
TLDR
These two species do not form a “hybrid swarm” in which much of the genome shows substantial introgression while disruptive selection maintains distinctness for only a few traits (e.g., pigmentation and male genitalia).
Multilocus analysis of introgression between two sympatric sister species of Drosophila: D. yakuba and D. santomea
3 Drosophila yakuba is widely distributed in sub-Saharan Africa, while D. santomea is endemic to the volcanic island of São Tomé in the Atlantic Ocean, 280 km west of Gabon. On São Tomé, D. yakuba is
EXTENSIVE INTROGRESSION OF MITOCHONDRIAL DNA RELATIVE TO NUCLEAR GENES IN THE DROSOPHILA YAKUBA SPECIES GROUP
Studies of gene flow between recently diverged species can illuminate the role of natural selection in the formation of new species. Drosophila santomea and D. yakuba are recently diverged, partially
EXTENSIVE INTROGRESSION OF MITOCHONDRIAL DNA RELATIVE TO NUCLEAR GENES IN THE DROSOPHILA YAKUBA SPECIES GROUP
TLDR
It is shown that the mtDNA must have recently introgressed across species boundaries in the D. yakuba subgroup and that its fixation was driven by either selection on the mitochondria itself or other cytoplasmic factors.
Inter‐island divergence within Drosophila mauritiana, a species of the D. simulans complex: Past history and/or speciation in progress?
TLDR
The discovery of pronounced geographic structure within D. mauritiana combined to genetic structuring and low gene flow between the two island populations illuminates the evolutionary history of the species and clearly merits further attention in the broad context of speciation.
Fine scale mapping of genomic introgressions within the Drosophila yakuba clade
TLDR
The genomic extent of introgression between the three species of the Drosophila yakuba clade is quantified and a new statistical framework, using a hidden Markov approach, is developed and applied to identify introgressed segments.
Fine scale mapping of genomic introgressions within the Drosophila yakuba clade
TLDR
The magnitude and genomic distribution of introgression among three species of Drosophila that encompass the two known stable hybrid zones in this genetic model genus is quantified and it is found that nuclear introgressive is rare between both species pairs.
Sequential adaptive introgression of the mitochondrial genome in Drosophila yakuba and Drosophila santomea
TLDR
At least two independent events of mtDNA introgression are uncovered in this study, including an early invasion of the D. yakuba mitochondrial genome that fully replaced the D .
SEXUAL ISOLATION BETWEEN TWO SIBLING SPECIES WITH OVERLAPPING RANGES: DROSOPHILA SANTOMEA AND DROSOPHILA YAKUBA
TLDR
Despite the fact that these species meet many of the conditions required for the evolution of reinforcement (the elevation of sexual isolation by natural selection to avoid maladaptive interspecific hybridization), there is no evidence that sexual isolation between the species is highest in the zone of overlap.
SEXUAL ISOLATION BETWEEN TWO SIBLING SPECIES WITH OVERLAPPING RANGES: DROSOPHILA SANTOMEA AND DROSOPHILA YAKUBA
Abstract.— .Drosophila yakuba is widespread in Africa, whereas D. santomea, its newly discovered sister species, is endemic to the volcanic island of São Tomé in the Gulf of Guinea. Drosophila

Evolutionary novelties in islands: Drosophila santomea, a new melanogaster sister species from São Tomé
TLDR
Drosophila santomea is reported on, which is the first melanogaster sibling found off West–equatorial Africa, on São Tomé, one of the Gulf of Guinea islands, and has a pure yellow body coloration of both sexes without the normal black abdominal banding.
Amylase gene duplication: an ancestral trait in the Drosophila melanogaster species subgroup
TLDR
Electrophoretic polymorphism of amylases was studied in 45 geographic populations of the two cosmopolitan sibling species and it is suggested that the duplication occurred in a common ancestor and the phylogenetic implications of these observations are discussed.
Molecular phylogeny and divergence times of drosophilid species.
TLDR
The phylogenetic relationships and divergence times of 39 drosophilid species were studied by using the coding region of the Adh gene to show that Scaptomyza experienced a rapid morphological evolution and many of the D. repleta group species studied here have two functional Adh genes, and these duplicated genes can be explained by two duplication events.

TLDR
Inferences of the times of species divergence from allozyme data are made and their agreement to other estimates is discussed and the yakuba-teissieri pair appears to be closer to the melanogaster lineage than to the erecta-orena one.
Amyrel, a paralogous gene of the amylase gene family in Drosophila melanogaster and the Sophophora subgenus.
TLDR
A gene from Drosophila melanogaster related to the alpha-amylase gene Amy, which exists as a single copy, was named Amyrel and it is suggested that this gene could result from a duplication of Amy followed by accelerated and selected divergence toward a new adaptation.
DNA sequence evolution of the amylase multigene family in Drosophila pseudoobscura.
TLDR
The nucleotide sequences of the three Amylase genes from a single chromosome of D. pseudoobscura are presented and it is inferred that Amy2 and Amy3 are more closely related to each other than either is to Amy1, and that Amy3 is nonfunctional and subject to random genetic drift.
Evidence for gene conversion in the amylase multigene family of Drosophila pseudoobscura.
TLDR
The homogenization effect of gene conversion has been strongest in SC, whose copies differ by only two nucleotides, less noticeable in ST, and negligible in the CH, which concur with the findings of other workers for the duplicated Amy genes in the Drosophila melanogaster group.

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.
Molecular evolution of the duplicated Amy locus in the Drosophila melanogaster species subgroup: concerted evolution only in the coding region and an excess of nonsynonymous substitutions in speciation.
TLDR
It is concluded that adaptive protein evolution occurred in the lineage of D. erecta that is a "specialist" species for host plants and probably also occurs in the process of speciation in general.
Fragmented forests, evolving flies: molecular variation in African populations of Drosophila teissieri
TLDR
It seems probable that the Drosophila teissieri species has undergone abrupt changes involving isolation, merging and migration of populations, as a consequence of repeated waves of forest fragmentation and coalescence.
