Divergent selection and heterogeneous genomic divergence
TLDR
It is concluded that divergent selection makes diverse contributions to heterogeneous genomic divergence, and the number, size, and distribution of genomic regions affected by selection varied substantially among studies, leading us to discuss the potential role of Divergent selection in the growth of regions of differentiation (i.e. genomic islands of divergence), a topic in need of future investigation.

Comparative genome sequencing of Drosophila pseudoobscura: chromosomal, gene, and cis-element evolution.
TLDR
A pattern of repeat-mediated chromosomal rearrangement, and high coadaptation of both male genes and cis-regulatory sequences emerges as important themes of genome divergence between these species of Drosophila. Expand
The origins of reproductive isolation in plants.
TLDR
Important questions for the next decade include identifying the evolutionary forces responsible for chromosomal rearrangements, determining how often prezygotic barriers arise due to selection against hybrids, and establishing the relative importance of genomic conflicts in speciation. Expand
Strong Amerind/white sex bias and a possible Sephardic contribution among the founders of a population in northwest Colombia.
TLDR
A highly asymmetric pattern of mating in early Antioquia, involving mostly immigrant men and local native women is indicated, with the frequency of the four Amerind founder lineages being closest to Native Americans currently living in the area. Expand
Autosomal, mtDNA, and Y-chromosome diversity in Amerinds: pre- and post-Columbian patterns of gene flow in South America.
TLDR
Admixture analysis of the Colombian populations suggests an asymmetric pattern of mating involving mostly immigrant men and native women, and the concordance of these estimates does not support an important difference in migration rates between the sexes throughout the history of South Amerinds.

Genomic evidence for the parallel evolution of coastal forms in the Senecio lautus complex
TLDR
Phylogenetic analysis of a broad selection of Senecio species showed that members of the S. lautus complex form a distinct lineage that has diversified recently in Australasia, consistent with a process of parallel ecotypic divergence in face of gene flow. Expand
The Genetics and Ecology of Reinforcement
TLDR
Reinforcement, the evolution of prezygotic reproductive barriers by natural selection in response to maladaptive hybridization, is one of the most debated processes in speciation and recent theoretical and empirical work on genetics and ecology of reinforcement suggests it can be overcome. Expand
USING COMPARATIVE GENOMIC DATA TO TEST FOR FAST-X EVOLUTION
TLDR
Paired comparisons are more powerful for examining rates of evolution of genes when X-linked over autosomal, and are concluded to be consistent with fast-X evolution. Expand
Microsatellites provide evidence for Y chromosome diversity among the founders of the New World.
TLDR
The hypothesis of a single-founder Y haplotype for Amerinds is evaluated by using 11 Y-specific markers in five Colombian Amerind populations to demonstrate the existence of at least two Amerind founder haplotypes, one of them largely restricted to Native Americans. Expand
Gene expression divergence and the origin of hybrid dysfunctions
TLDR
This review discusses recent studies that may contribute to the understanding of the genetic disruptions leading to hybrid dysfunctions and describes three systems that have been analyzed recently with respect to global patterns of gene expression in hybrids versus pure species, each in Drosophila.
