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 …

Levels of genetic differentiation between populations can be highly variable across the
genome, with divergent selection contributing to such heterogeneous genomic divergence …

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 origin of biological diversity, via the formation of new species, can be inextricably linked
to adaptation to the ecological environment. Specifically, ecological processes are central to …

The suggestion that chromosomal rearrangements play a role in speciation resulted from the
observation that heterokaryotypes are often infertile. However, the first chromosomal …

There is a growing appreciation that chromosome inversions affect rates of adaptation,
speciation, and the evolution of sex chromosomes. Comparative genomic studies have …

The role of natural selection in speciation, first described by Darwin, has finally been widely
accepted. Yet, the nature and time course of the genetic changes that result in speciation …

How common is speciation‐with‐gene‐flow? How much does gene flow impact on
speciation? To answer questions like these requires understanding of the common …

Since Darwin first proposed that new species could arise without geographic separation,
biologists have debated whether or not divergence occurs in the presence of gene …

Hybridization has a major role in evolution—from the introgression of important phenotypic
traits between species, to the creation of new species through hybrid speciation. Molecular …
