Alleles that introgress between species can influence the evolutionary and ecological fate of
species exposed to novel environments. Hybrid offspring of different species are often unfit …

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

In recent years, scientists have realized that evolution can occur on timescales much shorter
than the" long lapse of ages" emphasized by Darwin—in fact, evolutionary change is …

As populations diverge, genetic differences accumulate across the genome. Spurred by
rapid developments in sequencing technology, genome-wide population surveys of natural …

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

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

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 …

Speciation is a continuous process during which genetic changes gradually accumulate in
the genomes of diverging species. Recent studies have documented highly heterogeneous …

Abstract The European sea bass (Dicentrarchus labrax) is a temperate-zone euryhaline
teleost of prime importance for aquaculture and fisheries. This species is subdivided into two …

The emerging field of speciation genomics is advancing our understanding of the evolution
of reproductive isolation from the individual gene to a whole-genome perspective. In this …
