Speciation, the evolution of reproductive isolation among populations, is continuous,
complex, and involves multiple, interacting barriers. Until it is complete, the effects of this …

Hybridization among diverging lineages is common in nature. Genomic data provide a
special opportunity to characterize the history of hybridization and the genetic basis of …

Genome-scale sequence data have invigorated the study of hybridization and introgression,
particularly in animals. However, outside of a few notable cases, we lack systematic tests for …

Species can be defined as populations that are diagnosably distinct, reproductively isolated,
cohesive, or exclusive groups of organisms. Boundaries between species in sympatry are …

The metaphor of 'genomic islands of speciation'was first used to describe heterogeneous
differentiation among loci between the genomes of closely related species. The biological …

Speciation is a fundamental evolutionary process, the knowledge of which is crucial for
understanding the origins of biodiversity. Genomic approaches are an increasingly …

Speciation events often occur in rapid bursts of diversification, but the ecological and genetic
factors that promote these radiations are still much debated. Using whole transcriptomes …

Hybridisation and introgression can dramatically alter the relationships among groups of
species, leading to phylogenetic discordance across the genome and between populations …

Fruit flies of the genus Drosophila have been an attractive and effective genetic model
organism since Thomas Hunt Morgan and colleagues made seminal discoveries with them …

Several methods have been proposed to test for introgression across genomes. One method
tests for a genome-wide excess of shared derived alleles between taxa using Patterson's D …
