Empirical data suggest that inversions in many species contain genes important for
intraspecific divergence and speciation, yet mechanisms of evolution remain unclear. While …

Speciation is a key evolutionary process that is not yet fully understood. Combining
population genomic and ecological data from multiple diverging pairs of marine snails …

Genomic scans of multiple populations often reveal marker loci with greatly increased
differentiation between populations. Often this differentiation coincides in space with …

Understanding what determines range expansion or extinction is crucial to predict the
success of biological invaders. We tackled this long-standing question from an unparalleled …

Hybrid zones have been promoted as windows on the evolutionary process and as
laboratories for studying divergence and speciation. Patterns of divergence between …

Chromosomal inversions have long been recognized for their role in local adaptation. By
suppressing recombination in heterozygous individuals, they can maintain coadapted gene …

Adaptive divergence and speciation may happen despite opposition by gene flow.
Identifying the genomic basis underlying divergence with gene flow is a major task in …

Chromosomal rearrangements can lead to the coupling of reproductive barriers, but whether
and how they contribute to the completion of speciation remains unclear. Marine snails of …

Parallel evolution of similar phenotypes provides strong evidence for the operation of natural
selection. Where these phenotypes contribute to reproductive isolation, they further support …

The genetic basis of parallel evolution of similar species is of great interest in evolutionary
biology. In the adaptive radiation of Lake Victoria cichlid fishes, sister species with either …
