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

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 …

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 …

Ecological speciation is the process by which reproductively isolated populations emerge as
a consequence of divergent natural or ecologically-mediated sexual selection. Most …

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 …

Divergent natural selection has been shown to promote speciation in a wide range of taxa.
For example, adaptation to different ecological environments, via divergent selection, can …

Speciation with gene flow is expected to generate a heterogeneous pattern of genomic
differentiation. The few genes under or physically linked to loci experiencing strong …

Genes under divergent selection flow less readily between populations than other loci. This
observation has led to verbal “divergence hitchhiking” models of speciation in which …

Population genomic studies are beginning to provide a more comprehensive view of
dynamic genome-scale processes in evolution. Patterns of genomic architecture, such as …

Adaptive introgression can provide novel genetic variation to fuel rapid evolutionary
responses, though it may be counterbalanced by potential for detrimental disruption of the …
